How do I preserve evidence, like a defective product or damaged vehicle, for my California injury claim?

To preserve crucial evidence for a California injury claim, you must immediately secure and document the item and formally notify all parties that the evidence must be saved. Failing to do so can severely harm your case. Here is how to properly preserve evidence like a defective product or a damaged vehicle: Step 1: Document Everything Immediately Before the evidence is moved or altered, take extensive photos and videos from every possible angle. For a vehicle, photograph the exterior damage, the interior, the point of impact, and any tire marks. For a product, capture images of the defect, warning labels, and any serial or model numbers. Step 2: Take Secure Possession Gain physical control of the evidence to prevent its loss or alteration. For a vehicle, this means instructing the tow yard or body shop not to repair, sell, or destroy it. You may need to pay storage fees to prevent it from being auctioned. For a smaller product, place it in a sealed, labeled bag or box and store it in a secure location where it will not be disturbed. Step 3: Send a Preservation of Evidence Letter This is a critical step. You or your attorney must send a formal letter, often called a "spoliation letter," to all potential defendants (e.g., the other driver, the product manufacturer, their insurance companies). This letter legally notifies them of their duty to preserve the evidence for inspection. Step 4: Maintain a Chain of Custody Keep a simple, written log of where the evidence is stored and who has access to it. This record helps prove that the item has not been tampered with since the incident. Important Details: Do not attempt to repair, alter, or even clean the evidence. Changes to the item, however well-intentioned, can compromise your claim. Insurance companies may act quickly to take possession of a totaled vehicle and sell it for scrap, so you must act fast to put a hold on it. Warnings and Limitations: Under California law (including CACI 204 and Evidence Code 413), if you or the opposing party willfully destroys or conceals evidence, a court can impose serious sanctions. These may include financial penalties or an instruction to the jury that they should assume the lost evidence was unfavorable to the party who destroyed it. This can destroy a case. This is general information and does not constitute legal advice. For complex situations, and especially for sending formal legal notices like a preservation letter, you should consult with a qualified California attorney.
