Comparative Negligence in California: How Being Partly at Fault Affects Your Claim
California follows a pure comparative negligence rule, established by the California Supreme Court in Li v. Yellow Cab Co. (1975). That means you can recover damages even if you were mostly at fault—your award is simply reduced by your percentage of responsibility. If you are found 30% at fault on a $100,000 claim, you recover $70,000. Insurers use this rule to shift blame, which is why fault percentages are worth fighting over.
What is pure comparative negligence?
Under pure comparative negligence, each party’s fault is assigned a percentage and each pays for the share of harm they caused. Unlike “modified” states that bar recovery once you cross 50% fault, California lets an injured person recover even at 99% fault—the recovery is just reduced accordingly. This makes California one of the more plaintiff-protective states in the country.
How is fault decided?
Fault is decided by the evidence: the police report, physical evidence, witness statements, traffic laws that were violated, and sometimes expert reconstruction. Insurance adjusters propose a fault split, but it is a negotiation—and ultimately a jury question if the case goes to trial. Because every percentage point comes straight out of your recovery, documenting the other driver’s negligence early matters.
Why do insurers push comparative fault?
Every share of fault they can pin on you lowers what they pay. Adjusters routinely argue you were speeding, distracted, or could have avoided the crash. You are not required to accept their number, and you should be careful about recorded statements that can be used to build a comparative-fault argument against you.

Frequently Asked Questions
Can I still recover if I was partly at fault for my accident?
Yes. California’s pure comparative negligence rule lets you recover even if you were mostly at fault. Your damages are reduced by your percentage of fault—so at 30% fault you recover 70% of your damages.
What is the difference between pure and modified comparative negligence?
In pure comparative negligence (California), you can recover no matter how high your fault percentage, reduced accordingly. In modified comparative negligence states, you recover nothing once your fault reaches 50% or 51%.
Who decides my percentage of fault?
Insurers propose a split during negotiations, but if the case goes to trial a jury decides. Fault is based on the evidence—police reports, witnesses, physical evidence, and traffic-law violations.
