California Pure Comparative Fault Law CCP 1431.2
No Win No Fee Guarantee. Always Free Initial Consultations.
California’s pure comparative fault law gives every injured person the right to recover compensation, even if they’re partially responsible. Under Civil Code 1431.2, also known as Proposition 51, your payout is reduced by your percentage of fault but never cut off completely.
If you are dealing with medical bills, missed work, and an insurance adjuster who keeps pushing back, understanding how this law works is one of the most important things you can do to protect your claim.
Insurance companies are not neutral in this process. They assign fault percentages strategically, knowing that every point they add to your side of the ledger directly reduces what they owe you. The first number an adjuster gives you is not objective math, it is an opening negotiating position designed to cost you money.
In this legal guide covering California law, you will discover how pure comparative fault works, how Civil Code 1431.2 splits responsibility between multiple at-fault parties, and what steps you can take to protect your claim in California.
What Is Pure Comparative Fault in California?
California is a pure comparative fault state. This means that even if you were partly to blame for an accident, you can still recover money for your injuries.
Most states cut off your right to compensation once your share of the fault reaches a certain percentage. California does not. Here, your payout is reduced by whatever percentage of fault is attributed to you, even if that figure is as high as 99 percent.
This rule came from the 1975 California Supreme Court case Li v. Yellow Cab Co., which replaced the old “contributory negligence” system. Under the former contributory negligence system, any degree of fault could bar a person from recovering damages.
What Does Civil Code 1431.2 Say?
Civil Code 1431.2 is the statute voters passed as Proposition 51 in 1986, also called the Fair Responsibility Act. Many people search for “CCP 1431.2,” but the law actually lives in the California Civil Code, not the Code of Civil Procedure.
This statute governs how multiple at-fault parties pay for your injuries. It splits your compensation into two categories and treats each one differently:
- Economic damages: Every at-fault party is jointly and severally liable. This means you can collect the full economic amount from any one of them, regardless of their individual fault percentage.
- Non-economic damages: Each at-fault party only pays their own share. If a defendant is 30 percent at fault, they are responsible for 30 percent of your non-economic damages and no more.
“Joint and several” simply means that for economic damages, all at-fault parties are responsible together. If one cannot pay, the others must cover the full amount.
How Fault Reduces Your Recovery?
Your fault percentage comes directly off the top of your total award. Here is how the math works on a $100,000 case:
| Your Fault | Total Damages | What You Recover |
| 0% | $100,000 | $100,000 |
| 25% | $100,000 | $75,000 |
| 50% | $100,000 | $50,000 |
| 99% | $100,000 | $1,000 |
The “pure” part of the rule is exactly why even a 99 percent at-fault person still recovers something. No other rule in the country is this protective of injured people.
One important thing to understand: the first fault number an insurance adjuster gives you is not the final one. We fight to lower your fault percentage because every point we remove puts more money in your pocket.
What we consistently see in Northern California personal injury cases is that the fault percentage the insurance company assigns to our client on the first call bears almost no relationship to the evidence-supported percentage that survives contested negotiation.
Adjusters apply the maximum number they can defend with the available information, which in the early stages of a claim is often limited to a police report and the at-fault driver’s statement. Once we introduce signal phase data, surveillance footage, and vehicle event recorder data, the initial fault assignment routinely changes significantly in our client’s favor.
What Are Economic and Non-Economic Damages?
Economic damages are the direct financial losses you can calculate with a receipt or a pay stub. These are the bills and lost paychecks that pile up while you are unable to work.
Examples of economic damages include:
- Medical bills, both past and future
- Lost wages during recovery
- Future medical care and rehabilitation
- Property damage to your vehicle
- Lost earning capacity if your injury limits your ability to work long-term
Non-economic damages are the personal costs of your injury that do not come with a price tag. These cover how the injury has changed your daily experience of life.
Examples of non-economic damages include:
- Physical pain and suffering
- Emotional distress
- Loss of enjoyment of activities you used to do
- Loss of companionship or support for a spouse or family member
These two categories are treated very differently when more than one person caused your injuries, which is where Civil Code 1431.2 becomes especially important.
How Multiple Defendants Change Your Payout?
When more than one party is at fault, the numbers get more complicated. Here is a real example to show you exactly how it works.
A rideshare driver and a delivery truck both contribute to your crash. Your total damages are $200,000, with $120,000 in economic damages and $80,000 in non-economic damages. The jury finds the rideshare driver 60 percent at fault, the truck driver 30 percent at fault, and you 10 percent at fault.
Here is how the court applies the law:
- Step one: Reduce the full $200,000 by your 10 percent fault, which leaves a total of $180,000.
- Step two: The $108,000 in economic damages can be collected in full from either the rideshare company or the truck company, whichever has the money to pay.
- Step three: The $72,000 in non-economic damages is divided by fault. The rideshare driver pays $43,200 and the truck driver pays $21,600.
This split matters a great deal when one defendant has no insurance or no money to pay. You can still recover all of your economic damages from the solvent defendant to cover your hospital bills and lost wages. However, you cannot shift the uninsured defendant’s share of non-economic damages onto the other party.
How Is Fault Decided in California?
Fault is not permanently fixed by the police report. It moves through three stages as your case develops.
- Stage one: Insurance adjusters set an early fault number, usually one that benefits their company.
- Stage two: Lawyers negotiate that number using evidence and legal arguments.
- Stage three: If no agreement is reached, a jury makes the final call at trial using jury instructions called CACI 405 and 406.
The evidence used to move that fault number includes police reports, dashcam and surveillance footage, cell phone records, vehicle data, witness statements, and medical records that document the timing of your injuries.
Surveillance footage can be overwritten shortly after it is recorded. This is why taking action immediately after an accident is so important.
What to Do After an Accident to Protect Your Fault Percentage
The actions you take immediately after an accident can influence how fault is determined in your case.
Get medical care immediately. Seek treatment right away, even if you feel fine. Gaps in care give the defense room to argue your injuries were not serious or were caused by something other than the accident.
Save evidence and get witness information. Photograph the scene, the vehicles, and any visible injuries before anything changes. Write down the names and phone numbers of every witness before anyone leaves.
Do not give a recorded statement. You are not required to give a recorded statement to the other driver’s insurance company. We handle all communication with insurance adjusters so you do not say something that gets used to raise your fault percentage.
Common Tactics Insurance Companies Use to Raise Your Fault Percentage
The defense has a financial reason to push your fault number as high as possible. Every point they add to your side of the ledger directly reduces what they have to pay you.
Watch for these common tactics:
- Pre-existing condition claim: They argue your pain came from an old injury, not the accident, so they should not have to pay.
- Delayed treatment argument: They say you waited too long to see a doctor, which means your injuries must not have been serious.
- Speed or distraction claim: They argue you were speeding or distracted, even when their driver caused the crash.
- Comparative conduct claim: They argue your own choices in the moments before impact made the outcome worse than it needed to be.
We build a case from day one to counter each of these arguments before the defense has a chance to set the story.
In our experience litigating comparative fault disputes in Butte County and Sutter County Superior Courts, the pre-existing condition defense is the most commonly used tactic to increase the plaintiff’s effective fault percentage.
When an insurer successfully argues that your injuries were present before the accident, the economic damages portion of your case shrinks substantially, and the non-economic damages become harder to sustain before a jury.
We respond with the treating physician’s comparative analysis, which demonstrates that while some baseline condition may have existed, the accident caused a specific and documentable worsening that required treatment the client had never needed before.
Do Seatbelts, Helmets, and Assumption of Risk Affect Your Claim?
The seatbelt defense and the motorcycle helmet defense only reduce the portion of your damages that the device would have actually prevented. They do not eliminate your entire claim. A broken arm caused by a side impact, for example, is not affected by whether you wore a seatbelt.
Assumption of risk works differently depending on the situation. Primary assumption of risk applies in narrow situations like recreational sports where the other party owed you no duty of care at all, and it can fully bar your recovery. Secondary assumption of risk applies when you knowingly faced a danger created by someone else’s negligence. Courts treat this as a comparative fault issue, which simply reduces your compensation rather than ending your case entirely.
How Long Do You Have to File in California?
Most personal injury claims in California must be filed within two years of the date of the injury under California Code of Civil Procedure section 335.1. If a city, county, or state government agency was involved in your accident, you have only six months to file a government claim. Waiting also costs you evidence, since video footage disappears and witness memories fade quickly.

FAQs on California Pure Comparative Fault Law CCP 1431.2
Can I Recover Compensation if I Was Mostly at Fault for the Accident?
Yes. Under California’s pure comparative fault rule, you can recover compensation even if you were 99 percent at fault, though your award is reduced by your fault percentage.
How Does Prop 51 Affect My Payout When One Defendant Cannot Pay?
You can collect all of your economic damages from any solvent at-fault defendant, but each defendant only pays their own share of non-economic damages, so an uninsured party’s portion of pain and suffering cannot be transferred to anyone else.
Does Settling With One Defendant Reduce What I Can Collect From Another?
A settlement with one defendant can offset the economic portion of your award against the remaining defendant, but the non-settling party still owes their own share of non-economic damages based on their individual fault percentage.
Does Not Wearing a Seatbelt or Helmet Eliminate My Personal Injury Claim?
No. The defense can only reduce the portion of your damages that the seatbelt or helmet would have actually prevented, and the burden of proving that falls on them.
Am I Required to Give a Recorded Statement to the Other Driver’s Insurance Company?
No, you are not required to give a recorded statement to the other party’s insurer, and doing so often gives adjusters the material they need to increase your fault percentage.
Is CCP 1431.2 the Same Law as Civil Code 1431.2?
Yes. People commonly search for “CCP 1431.2,” but the statute is actually found in the California Civil Code section 1431.2, passed by voters as Proposition 51 in 1986.
