The jury instruction is the best tool for a diminished value claim in California. No appeals court has squarely ruled on lost value against an at-fault driver. Still, the instruction that judges read to juries covers it.
Jury Instruction CACI 3903J
California's civil jury instruction on property damage is CACI 3903J. It tells jurors that if a car can be repaired but will be worth less afterward, the owner gets two things. One is the gap between its value before the harm and its lower value after repairs. The other is the fair cost of the repairs.
The Matthiesen, Wickert & Lehrer chart of all 50 states calls the issue confusing in California. It says the instruction seems to allow a jury to award lost value. Bring that wording to the adjuster with a written appraisal.
Your Own Policy Turns on Its Wording
Claims against your own insurer depend on the policy. In Ray v. Farmers Insurance Exchange, from 1988, the court sided with the insurer. Making it pay lost value would gut its right to fix the car instead of paying cash value. Many policies now say outright that repair does not include lost value. Read yours before you ask.
Three Years for Property Damage
The California courts self-help site lists property damage as three years from the date the damage occurred. The rule sits in Code of Civil Procedure ยง 338, which covers injuring goods or chattels.
California also uses pure comparative fault. The state Supreme Court adopted it in Li v. Yellow Cab in 1975, so your share of blame lowers the award but does not end it.
New Minimums and Small Claims
Standard auto policies now carry higher floors. The California Department of Insurance says the property damage minimum rose to $15,000 per accident, up from $5,000. Older policies at the low limit may still be renewing, so ask the other driver's insurer for the real limit.
A person can sue for up to $12,500 in small claims court. Most lost value claims fit, and the court is built for people without counsel.
If the company stalls, use the department's consumer help page to file a complaint. Drivers who cross state lines can compare Arizona.
