What Is Comparative Negligence in California?
One of the most important — and most misunderstood — aspects of California personal injury law is comparative negligence. Many injured people don't pursue claims because they believe they were partly at fault. In California, being partly at fault does not bar your recovery. Here's how it works.
California's Pure Comparative Fault Rule
California follows 'pure comparative fault' (Li v. Yellow Cab Co., 1975). Under this rule, your damages are reduced by your percentage of fault — but you can still recover even if you were 99% at fault. This is different from 'contributory negligence' states (where any fault bars recovery) and 'modified comparative fault' states (where being more than 50% at fault bars recovery). California's rule is the most plaintiff-friendly in the country.
How Fault Percentages Work
A jury (or insurance adjuster in a settlement) assigns a percentage of fault to each party. If your total damages are $100,000 and you were found 30% at fault, you recover $70,000. The at-fault defendant pays their percentage: 70% × $100,000 = $70,000. If there are multiple defendants, each pays their proportionate share.
How Insurance Companies Use Comparative Fault
Insurance adjusters routinely use comparative fault to reduce settlement offers. They will look for any evidence that you contributed to the accident — speeding slightly, not wearing a seatbelt, being distracted — and assign you a fault percentage to reduce what they owe. This is why documentation at the scene is so important, and why having an attorney negotiate on your behalf matters.
Seatbelt Defense
California allows the 'seatbelt defense': if you were not wearing a seatbelt and your injuries would have been less severe if you had been, the defendant can argue your damages should be reduced. However, not wearing a seatbelt cannot be used to show you were negligent in causing the accident — only in failing to mitigate your injuries.
Comparative Fault in Premises Liability
In slip and fall and premises liability cases, property owners often argue the victim was comparatively negligent — they weren't watching where they were going, were wearing inappropriate footwear, or ignored warning signs. California courts evaluate whether the hazard was 'open and obvious' and whether the plaintiff acted reasonably. An attorney can counter these arguments effectively.
Government Entities and Comparative Fault
When a government entity is a defendant, California Government Code § 895.2 applies modified joint and several liability rules. The government entity pays only its proportionate share of non-economic damages, but is jointly and severally liable for economic damages. This is complex — consult an attorney if a government entity is involved.
Key Takeaways
- California uses 'pure comparative fault' — you can recover even if 99% at fault
- Your damages are reduced by your percentage of fault
- Insurance adjusters use comparative fault to reduce settlement offers
- Not wearing a seatbelt can reduce your damages but not bar your claim
- Multiple defendants each pay their proportionate share
- An attorney can counter inflated fault percentages assigned by insurers
Frequently Asked Questions
What if I was jaywalking when I was hit by a car?
You can still recover. A jury would assign you a fault percentage for jaywalking and reduce your damages accordingly. But if the driver was speeding, distracted, or failed to yield, they bear significant fault too. Many jaywalking accident victims recover substantial compensation.
Can the insurance company just decide I was 50% at fault?
They can claim it, but they can't unilaterally determine it. Fault percentages in settlements are negotiated. If you disagree with the insurer's assessment, you can negotiate, demand arbitration, or file a lawsuit where a jury decides. An attorney is essential for these negotiations.
Does comparative fault apply in wrongful death cases?
Yes. If the deceased was partly at fault, the wrongful death damages are reduced proportionately. However, the surviving family's own conduct is generally not factored in — only the deceased's comparative fault.
