A premises liability case is built or lost in the first 72 hours after the incident. A working-attorney guide to evidence preservation, notice, and CCP §2031.060 spoliation positioning.
Premises liability cases are won and lost on documentation. The legal standard under Rowland v. Christian (1968) 69 Cal.2d 108 is well-settled. A property owner owes a duty of reasonable care to those lawfully on the premises, the breach of which gives rise to liability for foreseeable harm. The doctrine is straightforward; the proof is not. By the time most plaintiffs walk into a lawyer's office, the surveillance footage has been overwritten, the wet-floor sign has reappeared, the broken handrail has been replaced, and the maintenance log has been redacted.
Most commercial surveillance systems overwrite on a 72-hour to 14-day cycle. Major retail chains run shorter loops than independent operators. Hotel and parking-structure systems vary widely. The single most important act in the first three days after a premises incident is a written preservation demand to the property owner, the operator, and any third-party security or maintenance vendor identified on-site.
The preservation letter should identify the date and time of the incident, the precise location (aisle, suite, entrance, parking row), the systems whose data should be preserved (CCTV, point-of-sale records, sweep logs, maintenance logs, incident reports, work orders), and the time window for each. Send it by a method that creates a paper trail: certified mail, return receipt, with an email copy to a verifiable address.
California recognizes evidentiary and instructional remedies for spoliation. The defining authority is Cedars-Sinai Medical Center v. Superior Court (1998) 18 Cal.4th 1, which rejected a separate tort cause of action for spoliation but preserved the trial court's authority to issue evidentiary, instructional, and discovery sanctions. CACI 204 (Willful Suppression of Evidence) and the standard preservation-of-evidence jury instructions remain powerful trial-positioning tools, but only if the predicate preservation demand was made on time.
A preservation letter creates the record that establishes notice. Once the defendant has notice and fails to preserve, the destruction is no longer accidental; it is litigation-positioning. The argument at trial writes itself.
Photograph the hazard, the surroundings, and the scale. Photograph any sign, posted notice, or warning that was or was not present. Photograph the lighting, the floor surface, the immediate environment. Photograph any witness who is willing to be photographed. Take more photographs than you think you need; the cost is zero and the value at trial is significant.
Photograph the plaintiff's injuries: the day of, the week of, and at every meaningful interval through treatment. Bruising, swelling, and surgical wounds tell a story that medical records summarize but do not capture. Treating physicians cannot describe what a juror cannot see.
Get names, phone numbers, and email addresses on-site. A witness with contact information is a witness; a witness without contact information is a memory. The on-scene incident report frequently captures partial information that the property owner uses to negotiate, and then withholds the full information in discovery. Independent witness identification by the plaintiff or counsel is the only reliable path.
Most commercial premises generate an internal incident report. The plaintiff has a right to that report in discovery, but the operator has a habit of producing a sanitized version. Request the original (the contemporaneous report, with the original signatures and timestamps) and preserve any inconsistencies between versions. Those inconsistencies become impeachment material at deposition.
Premises liability cases reward the lawyer who moves first. The preservation letter on day one is worth more than the demand letter on day ninety. If you have been injured on someone else's property in California, the cost of an early call is zero. The cost of waiting is the evidence that wins the case.
