What diminished value means
Two cars of the same year, model and mileage can sell for different prices when one has been in a crash. Buyers and dealers see the accident on vehicle history reports and offer less, even when the repair was done well. That gap between what your car was worth before the crash and what it is worth after repairs is what people call diminished value.
Diminished value is separate from the repair bill and separate from a total loss payout. If your car was totaled, read what happens when your car is totaled. If it was repaired, the question is how much value it lost. Newer cars, low-mileage cars and higher-priced models often show the largest gap, because buyers look harder at their history.
Who you can ask to pay
Most diminished value requests go to the insurance company of the driver who caused the crash. Your own policy may or may not cover it. The answer depends on the policy and the facts, and a lawyer can check. If the other driver had no insurance at all, read what to do when an uninsured driver hits you.
Fault matters. California uses pure comparative fault, so if you were partly to blame, what you can recover goes down by your share but does not disappear. The other driver’s limits matter too. For California policies issued or renewed since January 1, 2025, the minimum property damage coverage is $15,000. If repairs and lost value together go past the limit, the rest has to come from another source.

Evidence that supports a diminished value claim
Insurers rarely offer diminished value on their own. You usually have to ask in writing and back up the number. An independent appraisal from someone who values cars after repairs is often the starting point. Keep the full repair invoice, the parts list and photos of the damage before repairs. Write down whether the shop used new factory parts or other parts.
Dealer quotes help too. Ask two or three dealers what they would pay for your car today and mention the accident history, since they will see it anyway. Save the vehicle history report once the crash shows up on it. If the adjuster uses a formula, ask for a written copy of how they reached their number so you can compare it with your appraisal.
What to do now
Start with your health. If you were hurt at all, see a doctor, because an injury claim usually carries more weight than a claim for the car, and it has a shorter deadline. In California, an injury lawsuit must generally be filed within two years. Take photos of every car, the scene and any visible injuries, and get the names and phone numbers of witnesses.
Write down every claim number and adjuster name. Do not sign a release or give a recorded statement to the other driver’s insurer before you talk with a lawyer, because a property damage release can be worded broadly. Keep receipts for towing, a rental car and anything else you paid. For the full checklist, see what to do after a car accident in California.

Common questions
Can I get diminished value if the accident was my fault?
A diminished value request usually goes to the other driver’s insurer, so if you caused the crash there may be no one to ask. Whether your own policy covers lost value depends on its terms. If fault was shared, California’s comparative fault rule reduces what you recover by your share. A lawyer can read the policy and tell you where you stand.
How is diminished value calculated?
There is no single method everyone uses. Insurers often apply their own formulas, while appraisers compare your car’s value before the crash with its value after repairs, using market data and dealer offers. Ask the adjuster to explain their number in writing. If the offer seems low, read how to respond to a lowball offer.
Is there a deadline for a diminished value claim in California?
A lawsuit for damage to property such as a car must generally be filed within three years in California. Open the insurance claim much sooner, ideally within days of the crash. If you were also hurt, the injury deadline is generally two years, so plan around the earlier date.
Do I need a lawyer for a diminished value claim?
Many people handle a car-only claim on their own. A lawyer makes more sense when you were also injured, when the insurer refuses to pay any lost value, or when the damage goes past the other driver’s limits. Call us at (310) 552-6959 or use the form, and we can tell you whether your situation needs help.
