Do I Have a Case if I Was Partly at Fault?
California comparative negligence — why partial fault rarely means no recovery
Short answer: Yes — in California you can recover even if you were partly, or even mostly, at fault. California uses pure comparative negligence: your compensation is reduced by your percentage of fault, but you are never completely barred. Don't let an insurance adjuster talk you out of a valid claim by overstating your share of blame.
California is a "pure comparative negligence" state
Since the California Supreme Court's decision in Li v. Yellow Cab Co. (1975), California has followed pure comparative negligence. Under this rule, an injured person's damages are reduced in proportion to their own fault — but there is no cutoff that bars recovery. Even a driver found 90% at fault can still recover 10% of their damages.
This is more generous than many states, which use "modified" comparative negligence and bar recovery entirely once the injured person is 50% or 51% at fault. California has no such bar.
A simple example
Suppose your total damages — medical bills, lost wages, and pain and suffering — are $100,000, and you are found 20% at fault (say, for going slightly over the speed limit) while the other driver is 80% at fault for running a red light. You can recover $80,000 — your full damages minus your 20% share. If you were 50% at fault, you could still recover $50,000.
Why insurers push the "it was your fault" narrative
Because every percentage point of fault they can pin on you directly reduces what they pay, insurance companies have a strong incentive to overstate your share of blame. Common tactics include:
- Getting you to admit fault or apologize in a recorded statement (see dealing with insurance adjusters).
- Arguing you could have "avoided" the crash even when the other driver clearly caused it.
- Blaming a seatbelt, your speed, or a momentary distraction to inflate your percentage.
An insurer's opinion about fault is not the final word. Fault is ultimately decided from the evidence — and, if a case is tried, by a jury.
How fault is actually determined
Apportioning fault is an evidence-driven exercise. Key sources include the police (traffic collision) report, scene and vehicle-damage photos, witness statements, traffic-camera or dashcam footage, and sometimes accident-reconstruction experts. Strong evidence and skilled advocacy can push an unfairly high fault assessment back down — which, under comparative negligence, directly increases your recovery.
Note that when multiple parties are at fault, California's Proposition 51 also affects how damages are shared among defendants — see joint and several liability.
Frequently Asked Questions
Can I recover if I was partly at fault for a car accident in California?
Yes. California follows a pure comparative negligence rule, so you can recover even if you were partly — or even mostly — at fault. Your recovery is reduced by your percentage of fault. If your damages are $100,000 and you were 20% at fault, you can recover $80,000.
What is pure comparative negligence?
Pure comparative negligence means your damages are reduced by your share of fault but you are never completely barred from recovering. Unlike states that block recovery at 50% or 51% fault, California allows recovery even if you were 90% at fault — you would still recover 10% of your damages.
How is fault decided after a California crash?
Fault is determined from the evidence — the police report, photos, witness statements, vehicle damage, and sometimes expert analysis — and, if a case goes to trial, ultimately by a jury. Insurers often try to assign more fault to the injured person to reduce what they pay, which is why evidence and advocacy matter.
The insurance company says the crash was my fault. Should I give up?
No. An insurer's opinion about fault is not the final word, and insurers have a financial incentive to overstate your share of blame. Even if you were partly responsible, you may still have a valuable claim. An attorney can challenge an inflated fault assessment with the evidence.
