How to Litigate a Costco Injury Case in Texas

Short answer: A Texas Costco injury case is built by identifying the responsible operator and the condition that caused the harm, proving actual or constructive knowledge where premises liability applies, preserving time-sensitive records, establishing causation and damages, and answering defenses about notice and the injured person’s conduct. The fact that an injury occurred inside a warehouse is not enough.

Begin with the right legal theory

A spill or stationary obstruction usually raises a premises-condition claim. An employee’s contemporaneous operation of equipment may present a different negligent-activity question, but the label follows the actual conduct and timing, not the complaint’s wording. A falling display, powered equipment incident, defective product, parking-lot condition, or third-party act can add separate control and causation questions. Identify who owned or controlled the area and which entity employed or directed the relevant people. A membership card or receipt helps place a person at the warehouse; it does not resolve the legal classification.

For a premises claim, a plaintiff generally must prove actual or constructive knowledge of an unreasonably dangerous condition, an unreasonable failure to reduce or warn of the risk, and proximate causation. Texas courts do not treat retailers as insurers of all injuries. See Wal-Mart Stores, Inc. v. Reece, 81 S.W.3d 812, 814–17 (Tex. 2002); Brookshire Bros., Ltd. v. Aldridge, 438 S.W.3d 9, 28–30 (Tex. 2014). The April 2026 decision in H-E-B, LP v. Peterson, No. 24-0310 (Tex. Apr. 10, 2026), reinforced that older leaks elsewhere and a general inspection practice did not substitute for evidence of the puddle’s duration at the time and place of the fall. Its reasoning must be applied to the precise facts, rather than used as a blanket rule against all circumstantial evidence.

Build a timeline, not a collection of impressions

The key question is often when the hazard first appeared. A video may show a shopper dropping an item, liquid spreading, an employee passing, a cart rolling through, or nothing at all. Ask for cameras showing the condition, approaches, nearby work, and the period before and after the event. Check whether camera clocks match other clocks. A clip that begins 30 seconds before a fall may omit the decisive period. Inspection entries need their original timestamps, user identity, edit history, and an explanation of what “completed” means in the actual system. Do not assume Costco uses one uniform system or retention period in every warehouse.

Size, dirt, or footprints can prompt investigation, but they do not automatically prove duration. Reece, Wal-Mart Stores, Inc. v. Gonzalez, 968 S.W.2d 934 (Tex. 1998), and Peterson require careful treatment of speculative timing. Employee creation or an actual report to staff can supply a different route to knowledge if proved. An employee’s mere proximity requires context: what the employee could see, when, and whether the condition was discernible.

Preserve the evidence immediately

Report the event accurately; seek needed medical care; identify witnesses; photograph the condition from multiple angles without altering it; retain shoes, clothing, receipts, and original photographs; and note which cameras face the area. Counsel can promptly send a targeted preservation request identifying the incident window, cameras, native footage, exports, inspection data, incident communications, maintenance records, and relevant third-party material. Preservation requests do not guarantee that every recording exists or must be produced. If evidence is lost, Texas spoliation remedies require a judicial analysis of duty, breach, prejudice, and proportional sanction. Brookshire Brothers rejects an automatic adverse inference from every missing clip.

Test warehouse-specific explanations

At a warehouse, examine stocked pallets, packaging, product displays, carts, floor cleaning, food sampling, refrigeration, loading activity, and pedestrian routes if one of them matters to the accident. A low pallet or protruding merchandise may be a condition; moving equipment may involve active conduct. A wet entrance after rain requires evidence about the precise floor, drainage, mat condition, response, and timing. Food samples can create residue, but a nearby sample station alone does not prove a particular spill came from it. The case must connect each proposed mechanism to admissible evidence.

Prepare the defense and the damages record together

Costco may contest whether a condition was dangerous, whether it knew about it, whether a warning was adequate, whether another customer created it shortly before the fall, whether the claimant saw or should have seen it, and whether the claimed medical problems arose from this event. An open and obvious condition can affect duty under Austin v. Kroger Texas, L.P., 465 S.W.3d 193 (Tex. 2015), subject to fact-specific exceptions; it is not a universal defense to every injury. Texas proportionate responsibility may reduce or bar recovery under Chapter 33 of the Civil Practice and Remedies Code. Medical expense recovery is constrained by section 41.0105. Get the actual bills, payment adjustments, prior records, treating opinions, and evidence of future needs before proposing a value.

Litigation path

After investigation, counsel identifies defendants and timely files if settlement is not reached. Texas generally provides a two-year limitations period for personal injury, but accrual, tolling, defendants, and special rules require individual review. Discovery should be organized by elements: notice, response, causation, and damages. Depositions of employees, managers, video custodians, contractors, and a designated corporate representative should address knowledge and the systems actually used. Summary judgment is a foreseeable test of the notice evidence. If the case proceeds, the trial presentation must show the timeline through authenticated records and credible witnesses. Mediation should use the same evidence map, including weaknesses, rather than a demand detached from trial risk.

1 The case starts with an event reconstruction, not a retailer label

A person may be injured in a Costco warehouse without a viable claim against Costco. A lawyer’s first task is to fix the event: the exact place, surface or product, activity in progress, people who controlled it, injury mechanism, and earliest reliable evidence. A spill case needs a location-specific notice record; a powered pallet jack collision may turn on an operator’s immediate conduct; a fall from a defective cart may implicate the unit’s condition and its maintenance; and a vehicle impact in a lot may primarily involve a third-party driver. The term “Costco injury” is a useful search phrase, but it is not a cause of action.

Create an initial event sheet with warehouse address and club identifier, date and time including time zone, specific aisle or service area, approach direction, witness names, contemporaneous statements and scene changes after the event. Attach original photographs and receipts without replacing them with compressed copies. Distinguish what the claimant felt, what the claimant saw before injury, what someone said afterward, and what a later investigator inferred. A client may sincerely believe a cooler leaked because water lay near it; the litigation record must test the source. Record what remains unknown in a separate column. The temptation to fill gaps with an appealing warehouse narrative is especially dangerous because Texas constructive-notice law requires evidence tied to the actual hazard at the actual time and place.

A useful early diagram marks the exact floor patch, approach paths, cameras, adjacent activities, warning devices and changes during cleanup. Annotate the diagram as a demonstrative created from identified measurements, not a supposed photograph of conditions. If witnesses disagree about the location, retain competing versions until the original source files resolve them. The first interview should include how the person knows the time; clocks in an incident report, phone photo, camera overlay and cash register may disagree. Preserve all of them, then reconcile. This disciplined reconstruction supplies the spine for preservation, pleading, discovery, mediation and trial. It also helps counsel decline a claim when there is harm but no legally supportable route to duty, notice or causation.

2 Identify the operator, possession and responsible actors

A warehouse name on a receipt does not determine the correct legal defendant or who controlled an ancillary area. Investigate the entity operating the club on the incident date, property possession, relevant leases, service contracts, and employment or agency of the actor. A food demonstrator may have a separate employer; a parking-lot maintenance contractor may have a defined scope; a tire-service event may involve another set of duties and records. The inquiry is concrete: who could inspect the place, correct the condition, direct the relevant worker or preserve the relevant source? Do not plead a manufacturer merely because a product fell, or a landowner merely because a vehicle collision occurred there. At the same time, avoid assuming that a contract shifts every duty away from an occupier.

Start with public property information, the incident report’s entity name, service-area materials and photographs of signage. Request the controlling agreements only where ownership, possession, maintenance or indemnity genuinely bears on a claim or defense. A limited organizational deposition can ask a corporation to identify the operator and record keepers for this warehouse and date; notice the topics with reasonable particularity. The legal relationship among entities must be established from admissible records, not a corporate website or a witness’s colloquial use of “Costco.” A late-discovered party creates limitations and relation-back questions that deserve immediate analysis.

A proof chart should place each defendant in a row and list its alleged control, duty theory, injury-producing conduct, supporting source and competing explanation. For example, a sample vendor’s worker may have distributed food, but video may show an unknown shopper carrying a cup into a separate aisle. Without evidence connecting the vendor to the floor condition, the mere presence of a sample table is weak. Conversely, if a worker actively dropped the substance while serving, the person’s employer, supervision and immediate response may matter more than the schedule for a general aisle sweep. Separate entities and mechanisms early enough to preserve discovery against those who hold the relevant records.

3 Choose premises liability or negligent activity with care

Texas courts look to the nature of the injury-producing act. A static condition left on the floor ordinarily presents a premises claim. An employee operating equipment at the moment of impact may present a negligent-activity issue if the injury arose from that ongoing conduct. The fact that an employee earlier placed a pallet or spilled liquid does not automatically convert a later encounter with the resulting condition into negligent activity. *United Scaffolding, Inc. v. Levine*, 537 S.W.3d 463 (Tex. 2017), illustrates why labels and alternative pleading must track the actual proof. A falling box likewise may result from contemporaneous handling, a stack left unstable, another customer’s interference or a manufacturing issue. The timing of the actor’s conduct is critical.

For each theory, chart conduct or condition, defendant’s control, legal duty, notice where required, breach, proximate cause and damages. Ask what video shows in the seconds before injury rather than allowing a report’s “slip and fall” category to settle the issue. If a pallet jack was moving, obtain operator route, speed and sight-line evidence. If a pallet was stationary, investigate placement, visibility and duration. If a cart wheel failed, preserve the actual cart, service history and user account. Pleading multiple theories can be legitimate when facts remain uncertain, but counsel should not use negligent activity as a device to avoid a genuinely missing premises-notice element.

The classification matters at summary judgment and charge conference. A motion may attack the notice element for a static condition while overlooking supported contemporaneous conduct, or a plaintiff may argue an active theory unsupported by any evidence that an employee was doing anything at the time of harm. Revisit the chart after each key deposition. Address the theory in the language of the proposed charge, so a trial presentation built around “unsafe warehouse practices” does not leave the jury without proof of the submitted element.

4 The four propositions in a condition case

For an invitee’s premises-condition claim, organize proof around the operator’s knowledge of a condition posing an unreasonable risk, failure to exercise reasonable care to reduce or eliminate that risk, and proximate causation of harm, together with control of the condition and proper relationship. *H-E-B, LP v. Peterson*, No. 24-0310 (Tex. Apr. 10, 2026), restates the framework and insists on evidence connecting knowledge to the particular puddle. Proof of an injury and a wet floor after the fact does not itself prove notice. Nor is notice a complete case: a jury may still dispute whether the condition was unreasonably risky, how the operator responded, or whether the accident caused the claimed medical loss.

Build a proposition-to-source ledger. Under “condition,” list original scene photographs and witnesses who saw the material. Under “risk,” identify surface texture, lighting, warning and foreseeable use without converting an internal policy into the legal standard. Under “knowledge,” separate actual report, creation and constructive time. Under “response,” record warnings, cleanup or barriers and the interval available for them. Under “cause,” describe contact with the condition, body movement, contemporaneous symptom and alternate mechanisms. Under “damages,” list medical and functional records, prior condition and legally recoverable categories. For every entry add foundation, opposing inference and responsible witness.

This structure prevents a common proof error: using a single exhibit for a proposition it does not establish. A photograph of a puddle can show location after injury, but not necessarily its source or age. A worker’s route can establish proximity, but not necessarily visibility or awareness. A service ticket can establish a complaint about a unit, but not necessarily that the unit caused this spill. The goal is a series of supported inferences rather than one broad claim that “Costco should have known.” In a close case, the most important item is often a narrow missing link, such as a witness’s exact report time or an unproduced camera covering the source.

5 Actual knowledge requires a recipient, content and time

Actual knowledge can arise when a worker observes the hazard, receives a sufficiently specific warning or participates in creating it. Treat these as distinct routes to prove. A customer may say she warned “an employee near produce.” Counsel needs the precise location, words, appearance or identity of the recipient, how long before the fall and whether the report referred to the same condition. A worker’s later statement, “we had water problems,” may concern another section or a later discovery. An incident report entered after a fall is not, without more, a pre-fall warning.

Develop a warning through the reporting witness’s first account, call or radio traffic, manager communications, worker assignment and camera footage. Ask the witness what independent event fixes the time: a purchase, phone call, meeting with a companion or distinctive action on a camera. Do not feed a precise timestamp into an uncertain recollection. If the recipient was an independent vendor, investigate whether the report reached the occupier or whether the vendor’s role and actual knowledge bear on the duty at issue. The meaning of a report can also matter: “water near the freezers” in a long aisle may be too indefinite to identify the injury patch without a map and follow-up.

Suppose a shopper told a worker about a spill at 1:05, video shows the worker pointing at the precise spot at 1:08, and the fall occurred at 1:16. That combination supports receipt, identification and response opportunity, provided camera times are validated. If the pointing occurred after the fall or at another puddle, the inference collapses. Defense counsel will test every link. Plaintiff’s counsel should do so first and give the corporate witness a fair chance to identify the response. A clear actual-notice record may make a contested inference about how long liquid existed unnecessary; a vague warning should not be advertised as conclusive actual knowledge.

6 Employee creation, proximity and encounters

If a Costco employee caused a dangerous condition, determine exactly what action produced it, where the material traveled and when the member encountered it. A worker moving a leaking case is a plausible source, but the case may be dry or another shopper may have spilled a drink. Original video, product condition, cleanup observations and testimony should connect the act to the same condition. Timing can distinguish immediate negligent activity from a condition left for someone to encounter later. Do not treat a nearby uniform as evidence that the employee caused or saw anything.

*Wal-Mart Stores, Inc. v. Spates*, 186 S.W.3d 566 (Tex. 2006), illustrates why proximity alone does not prove constructive knowledge. Investigate distance, line of sight, orientation, lighting, obstruction, hazard conspicuity and time spent in a position to discover it. A worker carrying a tall pallet may have passed inches from a clear spill without a usable view. A worker walking slowly toward a dark object in a well-lit aisle may present a different inference. Map what the employee could see from a moving perspective rather than freezing a postfall close-up.

An encounter ledger records each worker or customer passing the spot, time source, path and possible observation. A passage is not automatically an inspection. A worker tasked with checking floors may nonetheless miss a newly formed transparent spill; conversely, an inspection marked complete may be contradicted by an original camera that shows the worker never reached the patch. Ask what the task called for, whether the record was made later and what the employee remembers independently. The strongest examination distinguishes seeing the area from seeing the hazard and a general safety responsibility from an actual opportunity to act.

7 Constructive notice after Peterson

Constructive notice requires evidence that this condition persisted long enough, under circumstances of visibility and proximity, that the occupier should have discovered it. *Wal-Mart Stores, Inc. v. Reece*, 81 S.W.3d 812 (Tex. 2002), emphasizes the temporal component; *Spates* rejects proximity without duration; *Wal-Mart Stores, Inc. v. Gonzalez*, 968 S.W.2d 934 (Tex. 1998), cautions against speculative age estimates. *Peterson* rejects reliance on earlier roof leaks elsewhere and a two-hour inspection gap to establish when the particular puddle existed. The decision does not impose a universal minimum number of minutes, nor does it rule out competent circumstantial evidence anchored to the same place and time.

Separate “last proved absence” from “first proved presence.” A clean floor at 2:00 followed by a fall at 2:30 shows the spill arose sometime in that interval, but does not prove it existed for 30 minutes. A reliable source image of the same liquid at 2:08 and a fall at 2:30 establishes a minimum 22-minute interval, subject to camera foundation and continuity. An unknown shopper entering at 2:28 may challenge whether the material shown earlier was the same hazard. If a puddle grows, describe the evidence of continuity and source, not merely a similar patch. The time calculation should be presented with a clock-offset worksheet and identified file frames.

A practical notice table has columns for earliest visible hazard, validation method, employee opportunity, visibility and alternative source. Populate each from evidence. The response to a no-evidence motion should point to the exact frame, transcript and authenticated record for each necessary inference. “The warehouse was busy” or “the area had leaked before” does not supply a duration by itself. When first-presence evidence is unavailable, pursue an actual warning or employee-creation route if facts support it. A candid conclusion that notice cannot presently be proved is valuable case judgment, not a drafting failure.

8 Hazard source and recurring conditions

A recurring leak, defective drain, troublesome mat or repeatedly displaced pallet can make a record worth investigating. It does not excuse proving what happened this time. Request records for the specific asset or floor location and a reasonable interval. Record unit number, reported symptom, repair action and whether the problem was resolved. Compare earlier reports for physical similarity, same location, source and response. A complaint about a different refrigerated case a month earlier may explain why counsel looked for records, yet be weak evidence of this puddle under *Peterson* and Rules 401 and 403.

Source reconstruction may require an engineer or qualified maintenance professional when a claimed mechanism is beyond ordinary observation. Give the expert actual measurements, drainage path, operating conditions, service records and viable alternatives such as a customer’s drink. An expert who can say a clogged drain was capable of producing water has not necessarily proved it produced the accident puddle or established when that puddle appeared. Avoid using scientific vocabulary to camouflage a missing temporal fact. The expert’s job is to explain a supported mechanism and its limits; lay witnesses and source recordings often supply the timing.

The same principle governs a sample station or stocked display. A location that often creates debris may support sensible inspection practices, but a particular piece of food still needs a source or duration record. If a worker admits placing it at a verified time, that is different from a general claim that food was served all day. Keep a “source alternatives” page in the file. For every proposed source, write what observation would distinguish it from a rival. This discipline makes discovery proportional and protects credibility in mediation and at trial.

9 The first seventy two hours

Prompt medical care, a reliable scene account and source preservation should run together. The claimant should report the event accurately and retain original photographs, footwear, clothing and any item involved, without washing or repairing it. If safe, wide photos should show the actual approach and warning locations before cleanup; close photos should show texture or material and a scale. Obtain witness contact information and the exact first statements, not an interview scripted around a theory. Ask for the incident report or a way to identify it, but do not assume the operator must immediately hand over internal materials.

Counsel’s preservation letter should identify claimant, location, incident time and a reasoned window extending before hazard origin and through response. Request source video, camera coverage map, exports and logs; any electronic or paper inspection entries and audit information; incident communications; relevant maintenance and staffing records; and third-party sources genuinely tied to the event. Invite the recipient to identify an unavailable source or unusually short retention cycle. Do not demand all footage from every warehouse for months. A narrowly justified request may be more effective and easier to enforce.

Maintain original digital files read-only, with working copies, source identifiers and transfer history. Save the claimant’s first account and note later corrections explicitly. A receipt can corroborate approximate presence but generally cannot locate the claimant at a spill throughout the visit. Medical intake records can establish immediate complaints and mechanism but can also contain shorthand errors; address discrepancies transparently. Early preparation should ask what evidence the defense will seek: prior relevant medical history, footwear, approach video and alternate source. Preserving the record for both sides improves the final evaluation.

10 Native video, camera mapping and clock reconciliation

A short clip of the fall may be least informative on notice. Start with a camera map: which views see the floor patch, approach, adjacent stocking or cleaning activity, warnings and first response? Ask whether recording is continuous or motion triggered and whether the original files are still available. Request a proportionate lead-up and response window, native or forensic-quality exports, codecs or player, camera identifiers, recording and display timestamp definitions, time-zone settings, frame timing, export history and retention information. Texas Rule of Civil Procedure 196 governs production of relevant electronically stored information, subject to proportionality and orders.

Preserve differences between original file, adjuster extract, enhanced view and courtroom clip. A brightened frame can clarify an object but can also exaggerate a reflection; a crop can conceal a warning; slow motion can make a normal interaction seem deliberate. Log every operation and show the normal-speed source first where appropriate. A knowledgeable custodian must explain the recording process and export. Rule 901 authentication can be satisfied in different ways depending on source, but the lawyer must know which witness or evidence establishes that this exhibit fairly represents what it purports to show. Consider Rules 1001 through 1003 and 403 when duplicates, altered views or misleading presentations are contested.

Compare timestamps to independent events cautiously. A camera running four minutes fast can still establish a within-camera interval if the offset is stable, but a second camera may use another clock. A purchase time, dispatch log and phone photo may reflect different time zones or synchronization. Maintain original displayed time, validated real-world time, uncertainty range and method. Do not testify through a graphic that quietly converts an approximation into a second-precise fact. A strong trial timeline can acknowledge a two-minute uncertainty while still proving a material interval.

11 Inspection records and the meaning of a completed sweep

The word “completed” is not a factual finding that the precise hazard patch was inspected. Determine the system and practice actually used at the warehouse and date. It might be a paper log, an electronic task entry or another arrangement. Ask for route and zone maps, author and device identity, event and submission times, edits, exception fields, supervisor permissions and any offline synchronization. The custodian should explain a field’s operational meaning rather than let the lawyers assign it from a screenshot. An employee should explain what she actually did, what she could see and how a task was marked complete.

Compare the source entry to video, staffing and physical route. An apparent contradiction may result from a clock difference, delayed entry or scope that excludes the accident patch. Investigate before alleging falsification. An inspection that occurred shortly before injury can support a reasonable-response defense, but a newly formed spill remains possible. A long interval without inspection may raise a practice question but cannot by itself establish duration of a newly formed spill after *Peterson*. The two propositions belong in separate columns: adequacy of the procedure and notice of the particular condition.

Authentication under Rule 901 and the business-record exception under Rule 803(6) require a knowledgeable foundation or valid certification; a narrative typed from another person’s report may raise Rule 805. An internal checklist is not automatically the legal duty. A comparative exhibit can display camera event, inspection entry creation, server receipt, any edit and fall time in parallel, with footnotes explaining uncertainty. This makes the record useful for a summary-judgment response and accessible to jurors without implying a software function that the club never used.

12 Incident communications, maintenance and third parties

An incident file may include photographs, notes, emails, manager messages, insurance communications and statements generated at different times and for different purposes. Preserve and classify them. A postfall statement can be a party admission or credibility evidence under applicable rules but does not necessarily prove prefall notice. A manager’s notation “found water by cooler” may simply describe the scene after injury. Ask when the manager arrived, who supplied each fact and whether the underlying statement was recorded. Privilege and work-product objections may be raised; counsel should request nonprivileged facts and sources with appropriate precision.

Maintenance records should be tied to the exact unit, floor section, cart or mat when possible. Their dates and reported symptoms matter more than volume. A log reporting “case leaking” before the fall may support an investigation, while a technician’s later conclusion that a gasket failed may bear on source, not necessarily the operator’s earlier knowledge. If a vendor performed service, identify possession of the record and the actor’s scope. A contract can show responsibility for inspection or cleaning, but the actual practice and retained control require testimony and facts.

Outside witnesses can be decisive: a shopper who reported the hazard, cleaner who wiped it, demonstrator at a sample table or paramedic who saw the scene. Interview promptly with open questions; preserve exact words and uncertainty. A witness’s honest “I don’t remember when” should not be converted into a fabricated timeline. At deposition, locate the witness physically and temporally before asking for opinions about what an employee should have seen. A source ledger that separates personal knowledge from hearsay makes later evidentiary objections easier to anticipate.

13 Missing video and spoliation

A missing recording prompts a source investigation, not an automatic inference that it proved liability. Establish whether a camera covered the relevant area, whether it recorded at that time, how long it retained files, who viewed or exported any clip, when the incident became known and when deletion or overwrite occurred. A camera map, system event log and earliest export may answer different questions. An adjuster’s 20-second clip could have been selected from a longer source, yet the missing remainder may show neither origin nor notice. Identify what proposition the lost portion plausibly could have addressed.

*Brookshire Bros., Ltd. v. Aldridge*, 438 S.W.3d 9 (Tex. 2014), places spoliation determinations with the trial judge and requires an analysis of preservation duty, breach, culpability, prejudice and proportionate remedy. A spoliation instruction is severe and limited. An ordinary overwrite before a preservation duty arose differs from deliberate deletion after a focused request. A preservation letter’s date matters but is not the only possible source of a duty. The loss of a view that never showed the floor differs from losing the only source capable of fixing a hazard’s duration. Do not treat sanctions as a substitute for proving substantive elements.

If evidence is missing, seek technical source information first, then a focused custodian deposition. Prepare a comparison of missing source, expected coverage, notice and deletion chronology, available substitutes and the specific requested remedy. Lesser relief might include additional discovery or limited testimony, subject to the court’s findings. An attorney should resist using the fact of an incomplete production in a public article as proof of wrongdoing in any particular Costco case. The doctrine is fact-specific and designed to cure prejudice proportionately.

14 Warehouse mechanisms beyond liquid spills

Pallets, stacked merchandise, moving equipment, carts, refrigerating units, entrance mats, fuel areas, food service and parking routes are distinct evidence problems. For a stationary pallet, measure protrusion, lighting and available aisle width, then investigate placement and duration. For merchandise that falls, reconstruct the original stack, packaging, access and potential customer interference. For a powered machine, record the operator’s path, load, speed and visibility. An expert reconstruction should disclose measurements and alternatives, especially when the video misses initial motion. Never assume every Costco location provides every ancillary service.

A case about a product display can fail if the scene was restacked before reliable photographs were taken. Preserve packaging and site measurements promptly. A cart defect may require the actual unit, maintenance history and a causal explanation for a wheel failure. A parking event may implicate a third-party driver and property-control questions. Water near a refrigerated case may come from a unit, a cleaner or a shopper; obtain the precise asset record and route of travel. Food near a sample station does not prove a demonstrator dropped it. The question is always what specific evidence connects a plausible mechanism to the event.

Create a mechanism matrix with columns for condition or act, possible actor, source evidence, notice theory if relevant, foreseeable defense and necessary expert. This turns “warehouse injury” from a generic marketing term into an efficient litigation investigation. Do not deploy a costly expert merely to say a wet floor is slippery; use expertise where engineering, biomechanics or electronic-system operation genuinely exceeds ordinary observation. Rule 702 reliability and fit apply to the expert’s proposed conclusion, not to the impressive nature of a résumé.

15 Warnings, open hazards and alternative routes

A wet-floor cone has legal significance only in context. Determine when it was placed, who placed it, what it warned about, whether it was visible from the claimant’s actual approach, and whether there was a safe practical alternative. A cone photographed after injury may have been placed during response. A video freeze frame showing the sign may differ substantially from the moving shopper’s view behind a cart. Reconstruct both perspectives with original footage and measured site geometry. Do not concede warning adequacy from the mere presence of a caution symbol.

*Austin v. Kroger Texas, L.P.*, 465 S.W.3d 193 (Tex. 2015), informs the ordinary rule for open and obvious conditions and the limited necessary-use exception. The duty issue is distinct from Chapter 33 comparative responsibility, although evidence can bear on both. Ask whether the risk itself was apparent, not merely whether a puddle could later be identified by an analyst enlarging a frame. Ask whether the injured person could reasonably use a different route. A warning after injury may be evidence of response rather than prior prevention.

At trial, use a scene diagram with measured sign and hazard positions and the claimant’s approach. Establish time and location foundation before displaying a postfall image. If a cone was moved, label versions of the scene. An effective cross-examination asks the warning witness when and where the sign stood and what independent record corroborates it, rather than assuming dishonesty. The stronger the warning record, the more important candid risk assessment becomes at mediation.

16 Medical causation, damages and value

A good injury case can lose value through imprecise medical proof. Record first symptoms, emergency or initial care, imaging, treatment, restrictions and functional change against the person’s prior baseline. A preexisting condition can be aggravated; a new symptom after a fall can also have another cause. An expert addressing complex causation should review material prior records and explain mechanism and alternatives. Do not ask a billing witness to prove medical causation. Separate a patient’s report from the clinician’s opinion and objective finding on a trial timeline.

Past medical expenses are limited by Texas Civil Practice and Remedies Code § 41.0105 to amounts actually paid or incurred, with *Haygood v. De Escabedo*, 356 S.W.3d 390 (Tex. 2011), informing the presentation. Reconcile bills, adjustments and payment status. Future care requires a credible treatment plan and reasonable cost support; future earnings require occupational and functional evidence. Non-economic damages should be tied to concrete effects and careful proof rather than a formula detached from evidence; see *Gregory v. Chohan*, 670 S.W.3d 546 (Tex. 2023). Liens, attorney fees and litigation costs affect net client recovery and should be analyzed separately from gross claim value.

A mediation chart can show a range under several liability findings and damages outcomes, with the underlying assumptions made explicit. Do not multiply arbitrary probabilities into a precise settlement “value.” Identify summary-judgment risk, an expert-exclusion issue, a strong warning, a likely preexisting-condition dispute and the cost of continued litigation. The client’s priorities are relevant, but the attorney should present a factual record rather than a guarantee of what a jury will do.

17 Discovery and corporate testimony by contested element

Targeted discovery starts from the proof ledger. A request for every Costco video or safety record nationally will likely obscure the actual event and invite justified proportionality objections. Seek the incident location and reasonable neighboring views, a bounded lead-up and response window, relevant inspection and audit fields, the specific equipment or display, direct incident communications and a limited set of comparable prior reports when genuinely probative. Rule 196 addresses electronically stored information and form of production. Confer about native files, field definitions, redactions and protective terms where privacy or technical burdens are real.

Depose the scene witnesses before or alongside system custodians. A floor worker should identify the route, actual observation, warning receipt and response. A video custodian should identify camera coverage, clock source, export and retention. An inspection-system witness should explain the data dictionary, editing, offline sync and the meaning of a completed row. A properly noticed corporate representative should address specified matters known or reasonably available to the organization, without treating the witness as the sole person who knows every event. Divide subjects among designees where appropriate.

For each deposition prepare three columns: proposition, authenticated exhibit and open question. Commit the witness to what the source actually establishes before asking for inferences. If a video witness says the camera had a blind spot, mark it on the map. If a manager admits a prior report, locate the exact condition, recipient and time. Discovery should narrow questions, not merely increase the file size. When a record does not exist, get a knowledgeable explanation of retention or system capability rather than citing a vague absence as evidence of concealment.

18 The Rule 166a motion and response

Notice is often the dispositive issue. A no-evidence motion may identify an absence of proof that Costco actually knew or had a reasonable chance to discover the hazard. A traditional motion may offer a supported contrary account. The response should distinguish actual report, employee creation and constructive duration and identify the admissible source for each route. A plausible theory unsupported by evidence cannot create a fact issue. *Peterson* deserves a direct explanation where a plaintiff relies on earlier maintenance, an inspection gap or general risk; ask whether the submitted evidence proves the same condition at the same time and place.

For motions filed on or after March 1, 2026, the amended Texas Rule of Civil Procedure 166a generally requires a response within 21 days of the motion’s filing; a hearing or submission generally cannot be set within 35 days of filing, and the rule includes further deadlines, exceptions and procedures. Calendar the actual filing, leave, orders, response and reply dates. Use the current text rather than a remembered former notice period. If essential evidence cannot yet be presented, a compliant declaration should identify what is needed, why, diligence and requested relief; speculation that something might exist is inadequate.

Organize the response by challenged proposition, source citation and foundational evidence. A still image should be supported by a competent witness or process evidence; an inspection export needs meaning and authenticity. Cite transcript page and exhibit identifiers, address objections and distinguish assumptions from direct observation. A proposed order and hearing outline should be consistent with the record. If a case lacks competent duration evidence and no other notice route exists, candidly reassess it before filing a response that recites only warehouse scale or general safety policies.

19 Mediation as a trial proof exercise

The strongest mediation submission does not promise that a jury will punish a large retailer. It lays out the actual condition, earliest supported existence, notice route, warning and response, mechanism, medical causation and disputed facts. Include key authenticated stills with original-file references and a clock reconciliation rather than a dramatic clip stripped of context. Acknowledge an alternative source or genuine timing uncertainty. The mediator and defense can test the presentation against a likely summary-judgment motion and trial objections.

Prepare three liability scenarios tied to specific proof: a reliable prior warning; reliable constructive duration; or unresolved notice. Prepare damages scenarios with recoverable past medical expense, supported future care and functional loss. Model comparative responsibility with evidence, not a reflexive percentage. Separately calculate client net after contract fees, documented costs and verified or estimated reimbursement claims. A written settlement term sheet should identify parties, released claims, payment timing, lien allocation, confidentiality if any, dismissal and approvals. Confirm the client’s informed authority and document material changes.

Negotiation can occur before filing, after key depositions or near trial, but limitations and preservation cannot wait for an adjuster to finish reviewing a claim. If a critical camera source remains unavailable, disclose the uncertainty rather than announce that a spoliation sanction will force settlement. If medical prognosis is immature, distinguish an early compromise from a fully informed valuation. Mediation is most effective when the evidence map is the same one counsel would use in the courtroom.

20 Voir dire, witness order and trial presentation

Jury selection should explore attitudes that bear on the case without asking jurors to precommit. Open questions can address expectations about retail safety, skepticism of falls without a visible hazard, trust in surveillance, whether a preexisting condition can be aggravated and comfort with compensation for pain or impairment. Follow up on jurors’ own answers, request rehabilitation where appropriate and preserve rulings. Do not convert a normal dispute over evidence into a claim that a juror must dislike Costco or favor an injured person.

Opening should state the precise condition or activity and supported notice route, preview weaknesses accurately and identify what original video will show. A sensible witness order may establish scene and first observations, then video source and clocks, inspection meaning, prior report or creation, reasonable response, medical causation and damages. A business-record custodian may authenticate a document but may not know whether an employee actually saw the floor. An expert may explain a reconstruction but cannot convert a blind spot into a recorded fact. Use each witness for the proposition that witness can truly support.

For impeachment, preserve the exact prior statement, date, page or timestamp, witness identity and opportunity to explain under Rule 613 where applicable. If a manager says in deposition no worker entered the aisle, original footage showing a worker may impeach; it does not automatically show the worker saw the spill. For expert cross, test source data, measurements, omitted frames, assumed spill source, error or uncertainty and alternative mechanisms. A video demonstrative should preserve the master, label crops and speed, and be shown only under the court’s rulings. Closing should track the actual charge question by question with admitted evidence, not an inference described as a recorded event.

21 Jury charge, postverdict record and publication integrity

Prepare charge questions early enough to expose gaps in proof. Premises elements, negligent activity when supported, proximate cause, proportionate responsibility and damages must fit the evidence and applicable Texas pattern and case law. Request correct wording in writing, make specific objections and obtain rulings. If the defendant disputes an unidentified third party’s role, review Chapter 33 procedure and actual support. Do not let the charge introduce an actor or theory that no witness or exhibit can connect to the event.

Postverdict motions and appeal issues are shaped by trial preservation. Record evidentiary objections and offers of proof where necessary, including exclusions of video enhancements or expert opinions. Preserve the admitted exhibit version and the source-to-demonstrative comparison. A persuasive verdict does not repair a missing notice element or cure a severe spoliation instruction entered without adequate findings. Trial preparation should therefore begin with the dispositive element ledger, not with a closing slide deck.

The worked illustrations in this guide are hypothetical, not Aaron Herbert case histories. A page that analyzes Costco litigation can demonstrate attorney-level rigor; it cannot establish a ranking or expertise claim by self-description. The goal is a useful legal reference grounded in verifiable sources and candid limitations.

22 A complete worked case from intake through motion

Consider a hypothetical fall at 2:18 p.m. near a refrigerated display. The member photographs liquid at 2:25 after cleanup has begun. A native aisle camera appears to show a shiny patch at 2:04, but a reflection could explain it; a separate view shows an employee walking through a neighboring aisle at 2:11. A digital inspection task reads “complete” at 2:08 but does not identify the floor patch. A shopper recalls telling someone wearing a warehouse badge about “water by the coolers” before the fall. A service ticket from the previous week mentions condensation at a different case.

The liability chart must keep possible proof routes apart. For constructive notice, identify the original 2:04 frames, test whether the patch is the same liquid and validate within-camera time and continuity. If a qualified comparison cannot distinguish liquid from reflection, do not use that frame to claim a 14-minute minimum. The 2:08 task may have covered an adjacent zone or may have been entered later; obtain audit fields, zone map and the worker’s route. The employee’s 2:11 passage may be irrelevant if the floor was not visible. For actual notice, interview the shopper for recipient, location, independent time anchor and words; seek related communications. The service ticket for another unit cannot silently stand in for a same-source history.

The defense may argue a member spilled a drink seconds before the fall, the task was properly completed and the 2:04 image is a light artifact. An admissible response to a no-evidence motion should cite only routes supported by competent sources. If the shopper can reliably establish a pre-fall report to a worker about the same floor patch, actual notice may survive even if the shiny image fails. If the image is reliably liquid and the source clock is sound, the minimum interval and visibility may support constructive notice. If neither route can be established, photographs after the event and generalized maintenance history may not rescue the claim under *Peterson*. This is how a serious investigation turns a sympathetic injury into a testable legal case.

23 A source and objection matrix for the attorney file

For every proposed exhibit, record what it proves, what it does not prove, how it will be authenticated and which objection is likely. Original surveillance can establish the visible scene and sequence, but a custodian or other adequate foundation must explain its source and timing. An enhanced clip may clarify detail, but preserve the master and disclose adjustments; anticipate an objection that crop, brightness or speed misleads. An inspection row may show a system event, but its field meaning, origin and embedded narrative may require distinct foundations. A customer’s earlier report may establish that notice was given even where the statement’s truth is disputed; identify the nonhearsay purpose and the recipient’s knowledge. A maintenance ticket may show an earlier complaint, but similarity and connection to the incident matter before it supports notice.

A useful matrix includes columns for source, exact proposition, creator or custodian, Rule 901 method, hearsay and multiple-hearsay analysis, Rule 403 risk, original versus derivative version, defense inference and planned witness. It should be revised after depositions and motions in limine. This matrix prevents counsel from discovering at trial that the only person able to authenticate a crucial overlay has left the company, or that a prior leak record relates to a different unit. It also makes mediation more credible: the attorney can say which links are solid and which are contingent on a ruling.

Rules of evidence are not a box-checking exercise. The specific objection depends on purpose. A record admitted to prove a system’s routine creation may not make every statement within it true. A video may be authentic but too distant to identify a transparent substance. A reconstruction may be relevant but fail Rule 702 reliability if based on guessed measurements. When an exhibit can support only a narrower inference, use it for that inference. Doing so protects the central proof story from overstatement.

24 How the pillar and focused pages work together

The pillar should answer the broad question of how a Texas Costco injury claim is investigated and litigated. Its linked clusters should answer narrower questions in enough depth to stand alone: proving notice; measuring time on the floor; first-day preservation; source video; inspection records; missing footage; pallets and falling goods; carts and moving equipment; refrigeration; entrances and parking; food or samples; warnings; member fault; medical proof; and the path through trial.

A reader concerned about a spill should be able to move from an immediate answer to the evidence timeline and then to the deeper video and inspection pages. A lawyer investigating a falling box should reach the pallet page, then the classification and expert sections here. The same concepts can appear in both places when the depth and purpose differ; copied paragraphs that answer no new question create a weaker reference.

This publishing architecture can make careful legal analysis easier to find and use. It cannot guarantee rankings, AI citations, referrals or a judgment about Aaron Herbert’s professional standing. Quality rests on accurate law, a distinct purpose for each page, specific evidence guidance, an honest author record and regular updates.
