Pure comparative negligence in California allows an injured person to recover damages even when that person shares fault for the accident. The recovery is reduced by the injured person’s percentage of fault.
For example, a person with $100,000 in damages who is 25% at fault may recover $75,000. If the person is 80% at fault, the recovery may drop to $20,000. The rule does not completely bar recovery just because the injured person was partly responsible.
What Is Pure Comparative Negligence?
Pure comparative negligence is a legal rule used to divide fault between the people or entities involved in an injury case. California adopted pure comparative negligence in the leading case Li v. Yellow Cab Co., which replaced the older contributory negligence rule.
Under contributory negligence, an injured person could lose the entire claim after sharing even a small amount of fault. California’s pure comparative negligence system works differently. A plaintiff may still recover damages, but the court reduces the award based on the plaintiff’s percentage of responsibility.
This rule can apply in many personal injury cases, including car crashes, bicycle accidents, pedestrian injuries, slip and falls, premises liability claims, dog bite disputes, and other negligence cases.
How Fault Percentages Affect Damages
In a comparative negligence case, the jury or parties may assign percentages of fault. Those percentages affect the final recovery.
A simple calculation may look like this:
- Total damages: $100,000
- Plaintiff fault: 30%
- Defendant fault: 70%
- Plaintiff recovery: $70,000
The same formula applies when the injured person holds most of the fault. A plaintiff who is 90% responsible may still recover 10% of proven damages. However, the lower recovery can affect settlement value, litigation strategy, and insurance negotiations.
California’s civil jury instruction on comparative fault explains how a jury may reduce a plaintiff’s damages when the plaintiff’s negligence contributes to the harm. That instruction reflects the practical role fault allocation plays at trial.
California Negligence Law
Most negligence cases start with the basic duty to use ordinary care. Civil Code Section 1714 states that everyone is responsible for injuries caused by a lack of ordinary care or skill in managing their property or person, except when the injured person’s own willful conduct or lack of ordinary care contributed to the injury.
That language fits comparative negligence. The injured person’s conduct does not always erase the claim. Instead, the court or jury may consider each side’s conduct and assign fault accordingly.
A defendant may argue the injured person acted carelessly. In a car crash, that argument may involve speeding, distraction, failure to yield, unsafe lane changes, or failure to wear a seat belt. In a slip and fall case, the argument may involve ignoring warning signs, walking in a restricted area, or failing to notice an obvious hazard.
Multiple Defendants and Shared Fault
Some cases involve more than one defendant. For example, a crash may involve two drivers, a defective road condition, and a vehicle maintenance issue. A premises liability case may involve a property owner, tenant, contractor, and security company.
California law may require the court or jury to divide fault among all responsible parties. Economic damages, such as medical bills and lost wages, may follow different responsibility rules than noneconomic damages, such as pain and suffering.
Under Civil Code Section 1431.2, each defendant is responsible only for that defendant’s percentage of noneconomic damages in personal injury, property damage, and wrongful death cases based on comparative fault. This rule can affect how much each defendant may owe after the court assigns fault.
Evidence That May Affect Fault
Comparative negligence cases often turn on evidence. The strongest evidence usually explains what happened, why it happened, and how each person’s conduct contributed to the injury.
Helpful evidence may include:
- Accident reports
- Photos or videos
- Witness statements
- Medical records
- Repair estimates
- Insurance communications
- Scene measurements
- Traffic citations
- Surveillance footage
- Expert analysis
- Text messages or phone records
- Weather or lighting information
Small details can matter. A photo of a broken stair, a traffic camera video, or a witness statement about speed may shift the fault percentage. Because percentages directly affect damages, evidence can strongly influence settlement discussions.
Comparative Negligence and Settlements
Insurance companies often use comparative negligence during settlement negotiations. An insurer may accept that an injury happened but argue the injured person caused part of the accident.
For example, an insurer may claim a pedestrian crossed outside a crosswalk, a driver reacted too slowly, or a customer failed to watch where they were walking. These arguments can reduce the settlement offer.
A fair settlement analysis should consider liability, damages, medical records, witness accounts, available insurance, and the likely fault allocation at trial. Her Lawyer’s article on what comparative negligence means explains the broader role comparative fault can play in injury claims.
Deadlines for California Injury Claims
Fault is not the only issue in a negligence case. Filing deadlines also matter. California Code of Civil Procedure Section 335.1 generally gives two years for an action involving injury to, or death of, a person caused by wrongful act or neglect.
Shorter deadlines may apply when a government entity is involved. Other rules may apply to minors, delayed discovery issues, medical negligence, or special claims. For that reason, timing should be reviewed early.
