California negligence law holds that a person is legally responsible for harm caused by a failure to use reasonable care. To prove negligence in California, a plaintiff must establish four elements: duty of care, breach of that duty, causation, and actual damages. California also follows a pure comparative negligence system, reducing compensation by the plaintiff’s percentage of fault.
These rules apply to every personal injury claim filed in California courts, from car accidents to slip and falls to medical malpractice.
To prove negligence in California, a plaintiff must establish four elements: duty of care, breach of duty, causation, and damages.
Comparative negligence in California follows a pure system, which means you can still recover damages even if you were partially at fault for the accident.
A concrete example: if your total damages are $100,000 and you are found 30% at fault, you recover $70,000. Your compensation is reduced by your percentage of fault, not eliminated.
The “pure” distinction matters. Unlike modified comparative negligence states that cut off recovery at 50% or 51% fault, California imposes no such cap. A plaintiff found 99% at fault can still recover 1% of their damages. The process for how fault is determined in a car accident follows the same percentage logic that applies to all California negligence cases.
Fault percentage is set by the jury following judge’s instructions under CACI 405. In settlements, the parties negotiate the split directly.
When multiple defendants share responsibility, California’s Civil Code § 1431.2 applies joint and several liability for economic damages but proportional liability for non-economic damages. Each defendant pays their share of pain and suffering, not the full amount.
In California, you generally have two years from the date of the injury to file a negligence lawsuit. This deadline is set by Code of Civil Procedure Section 335.1 and is part of the broader California negligence statute of limitations framework. The personal injury statute of limitations by state varies, in California, two years is the general rule for most negligence claims.
Four exceptions can change that deadline:
Missing the deadline typically bars recovery entirely. Courts rarely grant exceptions outside the ones listed above.
Negligence per se in California applies when a defendant violates a statute or regulation. That violation automatically establishes duty and breach without requiring the plaintiff to prove those elements separately. The legal basis is California Evidence Code Section 669.
Two conditions must be met:
A driver running a red light and hitting a pedestrian is a clear example. The traffic violation establishes negligence per se because traffic laws exist specifically to protect other road users.
Negligence per se does not eliminate the need to prove causation and damages. Those two elements still require evidence connecting the violation to the plaintiff’s actual losses.
Negligence claims in California arise most often from car accidents, slip and falls, medical malpractice, truck accidents, and product liability cases.
California personal injury lawyers and Santa Ana personal injury attorneys handle all of these claim types under the same four-element negligence framework, though local court procedures may vary.
Proving negligence in California requires evidence that connects the defendant’s conduct to your injury across all four elements: duty, breach, causation, and damages.
Common types of evidence include:
The standard of proof is preponderance of the evidence: more likely than not. That is a lower bar than the criminal “beyond a reasonable doubt” standard, but building a strong evidentiary record still requires deliberate effort from day one.
Evidence preservation is time-sensitive. Surveillance footage gets deleted, witnesses become harder to locate, and physical conditions change. The full breakdown of how to prove negligence in a personal injury case in California covers each element and the evidence that supports it.

Under California Civil Code § 1714, negligence is the failure to use reasonable care. A person is negligent when their conduct falls below the standard of care that a reasonably careful person would exercise in the same situation, resulting in harm to another.
Yes. California’s pure comparative negligence system allows recovery at any level of fault. Your compensation is reduced by your percentage of fault, but you are not barred from recovering. A plaintiff found 80% at fault can still recover 20% of their damages.
Negligence is a failure to use reasonable care. Gross negligence involves a more extreme departure from that standard, showing a reckless disregard for others’ safety. Gross negligence can support punitive damages in addition to compensatory damages.
Each party is assigned a percentage of fault. For economic damages, California applies joint and several liability. For non-economic damages, each defendant is only responsible for their proportional share under Civil Code § 1431.2.
