Preserving Evidence: Key Steps in a California Personal Injury Case

After an accident, your memory of what happened is not what wins your case — evidence is. Preserving evidence in a California personal injury case is one of the most consequential things an injured person can do in the first hours, days, and weeks after a crash, fall, or defective-product injury. The average plaintiff doesn’t always know what counts as evidence, so the working rule is simple: preserve anything that might matter, and let your attorney sort out what does.

The stakes are enormous. The National Highway Traffic Safety Administration reports that 40,990 people died in U.S. traffic crashes in 2023, and California’s SWITRS data compiled by the CHP records well over 150,000 people injured in traffic collisions statewide in a typical year. Behind every one of those numbers is a claim that will rise or fall on documentation.

Capture Ephemeral Evidence Before It Vanishes

One of the most important modern concepts in injury litigation is ephemeral evidence — digital content designed to disappear, often within 24 hours. Instagram stories, Snapchat posts, and “vanish mode” messages self-delete automatically, and users can also manually scrub content at any time.

Why does this matter to your case? Consider two examples:

• You were hit by a distracted driver who was texting moments before the crash. Distraction-affected crashes killed 3,275 people nationally in 2023, per NHTSA — but if those messages were sent in vanish mode, proving it becomes much harder once they’re gone.
• You slipped on a spill from a leaking water cooler, and the business now claims it never had a water cooler. What happens if every photo of it quietly disappears from their social media?

The most straightforward preservation method is the one in your pocket: screenshot the content immediately and forward copies to your lawyer. In higher-stakes cases, attorneys can also send litigation hold (spoliation) letters demanding that opposing parties preserve digital content — and there is even software that captures ephemeral posts automatically. The same urgency applies to surveillance and dashcam video, which many systems overwrite within days.

Make Copies of Everything

Photos of the crash scene live on your phone — until you lose the phone or the storage fails. Redundancy is cheap insurance:

• Back photos and videos up to cloud storage and an external drive
• Send your attorney copies of every file as you collect it
• Scan paper documents (medical bills, repair estimates, correspondence) rather than relying on a single original

Multiple layers of redundancy mean no single mishap can gut your case file.

Keep a Recovery Journal

Doctors’ notes are short, clinical, and sometimes barely legible. They rarely capture what your injuries actually cost you day to day. A journal fills that gap. Each day, record:

• Pain levels and symptoms
• How treatment and medications are going
• Emotional effects — anxiety, sleep loss, frustration, trauma
• Activities you could not do: work tasks, childcare, hobbies, household chores

Written or video entries both work. This record backs up your medical file and becomes powerful proof of non-economic damages — the pain-and-suffering component that insurance adjusters work hardest to minimize.

Keep Everything in Writing

A rule of thumb after any California accident: if it isn’t in writing, expect the insurer to dispute it.

• Route communications to paper or email. If an adjuster wants to discuss details by phone, politely ask for the request in writing — or direct them to your attorney. “Off-the-record” settlement conversations are a tactic, not a courtesy.
• File required reports promptly. Injured on public transit? Transit authority rules may require a written injury report. Hurt at work? Report it to your employer right away. Miss these filings and the insurer may later argue the incident never happened.
• Copy everything, both directions. Keep copies of every communication you send and receive. Email is ideal because it creates an automatic, timestamped archive.

Preserve Physical Evidence

In some cases, the physical object itself is the case. If a pressure cooker exploded, a ladder collapsed, or a vehicle component failed, do not throw it away and do not repair it. Collect every piece, store it safely, and let your attorney arrange proper chain-of-custody storage and expert inspection. In product liability claims, the defective product is often the single most important exhibit — and in car accident cases, the damaged vehicle itself should be photographed and inspected before it is repaired or salvaged.

Why Evidence Deadlines Are Shorter Than Legal Deadlines

California gives most injury victims two years to file suit under Code of Civil Procedure § 335.1, and only six months to present a claim against a government entity. But the practical deadlines are far shorter: surveillance systems overwrite footage in days, skid marks fade, vehicles get repaired, witnesses move, and ephemeral posts delete themselves on schedule. The clock that matters most starts the moment the accident ends.
