Quick answer
No set number of minutes answers this question. Start by finding out whether someone at Walmart knew about the spill before the fall. If so, examine what the store did after learning of it.
Constructive notice is the other possibility: the spill remained long enough that Walmart had a reasonable opportunity to discover it. To assess that opportunity, a court looks at duration, visibility and employee proximity together. The cases below explain why finding an employee nearby is not enough.
A search for “Walmart spill fifteen-minute rule” will not resolve a Texas claim. The law does not turn liability on a stopwatch alone. Nor does the absence of an exact start time necessarily end the investigation.
The Walmart injury guide explains the full claim. Here the question is time.
Why proximity does not supply the missing time
In Wal-Mart Stores, Inc. v. Spates, 186 S.W.3d 566 (Tex. 2006), an employee had stood a few feet from a clear plastic ring for thirty to forty-five seconds, facing away from it. The Supreme Court held the constructive-knowledge evidence insufficient. It applied the duration, proximity and conspicuity analysis from Reece.
Forty-five seconds is a fact from that case, not a deadline written into Texas law. The employee's view of the floor and the nature of the object were also part of the evidence.
What if the recording starts too late?
The puddle is there when the clip opens. You have a minimum interval, but no arrival time. Ask for the preceding footage and check whether a witness passed that spot earlier.

The gap since an inspection is a different interval
A two-hour gap in inspections does not mean the puddle was two hours old. It could have appeared at any point in that gap.
The Texas Supreme Court addressed this problem in H-E-B, LP v. Peterson, No. 24-0310 (Tex. Apr. 10, 2026). The record did not supply the necessary evidence of the particular puddle's duration. Earlier roof leaks elsewhere and the time since an inspection did not fill that evidentiary gap.
An inspection can still be valuable evidence. If a witness saw liquid before an inspection and footage shows what the employee did, the investigation has something more specific to work with. Obtain the inspection record and an explanation of it, then compare the claimed activity with the hazard's location.
What a witness can remember
People rarely time their shopping trips with litigation in mind. A witness may remember seeing a spill, going to another aisle and returning to find someone on the floor. Ask about the intervening events. A purchase, phone call or message might help locate the observation in time.
Find out what the witness used to estimate time. Photographs need interpretation too: footprints can show that someone crossed a spill without showing when it first appeared.
When duration is not the route to knowledge
If an employee saw the spill or received a sufficiently specific report before the fall, investigate actual knowledge. There is no reason to rely only on an argument that the store should have discovered something it already knew about.
Knowledge is only one element of the claim. A court must also consider reasonable care and causation. That includes the response to a report, not merely the fact that a report was made.
