California's pure comparative fault system allows injured parties to recover damages even when they were partly responsible for the accident. This is one of the most plaintiff-favorable fault systems in the United States.

What Is Pure Comparative Fault?

California Civil Code § 1714 establishes that everyone is responsible for injuries caused by their failure to exercise ordinary care. The California Supreme Court's landmark 1975 decision in Li v. Yellow Cab Co. (13 Cal.3d 804) established pure comparative fault as California's governing standard, replacing the prior contributory negligence rule that barred any recovery when the plaintiff was at fault.

Under pure comparative fault, fault is allocated among all parties as a percentage. Each party is responsible for their proportionate share of damages. Critically, there is no fault threshold — even a plaintiff who is 99% at fault may recover 1% of their damages.

How It Works in Practice

Example: A jury finds that the plaintiff's damages total $200,000. The jury also finds the plaintiff was 30% at fault (for example, for failing to maintain a proper lookout). The plaintiff's recovery is reduced by 30%: they receive $140,000.

In insurance claims, adjusters apply comparative fault informally during the claims process — assigning percentages before any jury is involved. These allocations are negotiable. An adjuster's initial fault allocation is not a court ruling and does not bind any subsequent litigation.

Joint and Several Liability

California Civil Code § 1431.2 (Proposition 51, 1986) modified joint and several liability in personal injury cases. Under § 1431.2, defendants are jointly and severally liable for economic damages (medical bills, lost wages) but are only severally (proportionately) liable for non-economic damages (pain and suffering). This means that in multi-defendant cases, each defendant pays their proportionate share of non-economic damages — the plaintiff cannot collect all non-economic damages from any single solvent defendant.

Impact on Insurance Claims

Comparative fault directly affects the settlement value of your claim. If you are found 20% at fault, a $100,000 damages case settles for approximately $80,000. Insurers routinely attempt to increase the plaintiff's comparative fault percentage during negotiations — each percentage point reduces their payment obligation. Understanding and rebutting inflated fault attributions is a core component of claims negotiation.

California Civil Code § 1714(a)

Everyone is responsible, not only for the result of his or her willful acts, but also for an injury occasioned to another by his or her want of ordinary care or skill in the management of his or her property or person.

California's pure comparative fault system (Civil Code § 1714) allows an injured party to recover damages even if they were partially at fault for the accident. Recovery is reduced by the plaintiff's percentage of fault — but there is no minimum fault threshold that bars recovery.

Each percentage point of comparative fault attributed to you reduces your recovery by that percentage. For example, 20% fault on a $100,000 claim yields $80,000. Insurance adjusters calculate comparative fault informally during negotiations — these allocations are not binding and are often negotiable.
