Being partly to blame does not end your claim in California. Here's how shared fault really works.
What Pure Comparative Negligence Means
California follows a 'pure comparative negligence' rule. Under it, you can recover compensation even if you were mostly at fault for your own injury — your award is simply reduced by your percentage of fault. If you are found 30% responsible, you recover 70% of your damages.
This is more generous than many states, which bar recovery once you cross 50% fault. In California, even someone who is 90% at fault can still recover 10%.
How Fault Percentages Are Decided
Fault is assigned by a jury (or by adjusters during settlement) based on the evidence: police reports, witness statements, physical evidence, traffic laws, and expert testimony. Each party involved can be assigned a share that adds up to 100%.
Insurance companies love to inflate the injured person's share to shrink what they pay. A well-documented case pushes back on those inflated numbers.
Common Ways Insurers Try to Shift Blame
Adjusters may argue you were speeding, distracted, jaywalking, not wearing a seatbelt, or that you 'assumed the risk.' Even when there is some truth to it, the percentage they assign is often exaggerated and negotiable.
This is why what you say after a crash matters so much. Admitting fault at the scene or to an adjuster can be used to drive your percentage up.
Seatbelts, Helmets, and the 'Mitigation' Argument
California allows defendants to argue that not wearing a seatbelt or motorcycle helmet increased your injuries. This does not erase your claim, but it can reduce certain damages. The defense must actually prove the gear would have changed the outcome.
An experienced attorney can often limit or defeat these arguments with medical and biomechanical evidence.
Multiple Defendants and Joint Liability
When more than one party is at fault, California splits responsibility. For economic damages like medical bills and lost wages, defendants can be held jointly responsible. For non-economic damages like pain and suffering, each defendant pays only its own share under Proposition 51.
Identifying every responsible party — and every insurance policy — is often the difference between partial and full compensation.
Protecting Your Share of the Recovery
The best protection is early, thorough documentation: scene photos, witness contact information, prompt medical care, and no recorded statements until you have advice. The goal is to keep your assigned fault as low as the facts allow.
