"They said I was partly at fault, so I don't have a case." I hear that sentence at least once a month, and it is almost always wrong.

California is a pure comparative fault state. That is one of the most important facts about California injury law, and one of the most misunderstood by the public. Let me explain what it actually means.

The basic rule

In California, if you are injured by someone else's negligence, you can recover damages even if you were partly at fault. Your recovery is reduced by your percentage of fault, but it is not eliminated. The leading case is Li v. Yellow Cab Co., decided by the California Supreme Court in 1975, which abandoned the older "all or nothing" contributory negligence rule.

Pure means there is no threshold. In some states, if you are 51 percent at fault you lose everything. Not in California. Even if a jury finds you 99 percent at fault, you can still recover 1 percent of your damages. As a practical matter, juries rarely assign extreme percentages to plaintiffs, but the rule is what it is.

How it actually plays out

Take a real example. A driver is hit broadside by another car that ran a red light. The plaintiff was going 5 mph over the speed limit. The jury finds the other driver 90 percent at fault for running the light and the plaintiff 10 percent at fault for speeding. Total damages are $500,000. The plaintiff recovers $450,000.

The same logic applies in slip and fall cases (was the hazard partly hidden? was the plaintiff looking at their phone?), bicycle cases (did the rider have lights at night?), and motorcycle cases (was the rider lane splitting safely?). It almost never reduces a case to zero, but it does affect the dollars.

What the defense does with it

Defense lawyers love comparative fault, because it gives them something to argue even when their client clearly caused the crash. Their goal is to push the plaintiff's percentage up. 10 percent becomes 20 percent. 20 becomes 35. Every increment costs the plaintiff money.

This is one of the main reasons evidence preservation matters so much. Scene photos, witness statements, surveillance footage, and accident reconstruction analysis all push back against comparative fault arguments. We discuss the broader role of evidence in how evidence impacts personal injury cases.

Comparative fault and insurance

Insurance adjusters use comparative fault aggressively in early negotiations. They will tell you, "Our investigation shows you were 30 percent at fault, so we are reducing our offer by 30 percent." Sometimes that is a legitimate assessment. Often it is an opening move designed to anchor the number lower. A good lawyer will push back, and if necessary, take the case to a jury and let the jury decide. The patterns of how insurers approach these arguments are covered in insurance company tactics.

Multiple defendants

Pure comparative fault also applies between defendants. If you are hurt in a multi vehicle crash, the jury allocates a percentage to each at fault driver and to you. Each defendant pays their share of economic damages joint and severally for the most part, but their share of non economic damages is several only, meaning each pays only their assigned percentage. This rule, from Proposition 51 in 1986, is one of the trickier corners of California injury law.

What this means for you

If you have been told you have no case because you were partly at fault, get a second opinion. Lawyers worth their fee will look at the actual evidence, not just the police officer's initial impression. Police reports are admissible in some contexts and not in others, and they are not the final word on fault.

The broader question of what separates a winning case from a marginal one comes up in what makes a strong personal injury case, and the full lifecycle of how a claim moves from accident to recovery is covered in how personal injury claims work.
