Comparative Negligence in California

What Is Comparative Negligence in California?

If you’ve been injured in an accident in California, you might assume one person must be completely at fault. However, California law recognizes that responsibility is often shared.

Comparative fault (also called comparative negligence) is California’s system for dividing responsibility when multiple parties contribute to an accident. Under this rule, each person’s share of fault is expressed as a percentage, and your compensation is reduced by your percentage of responsibility—but you can still recover damages even if you’re mostly at fault.

California’s Pure Comparative Fault Rule

California uses “pure” comparative fault, which means:

• You can recover damages even if you were 99% at fault
• Your award is simply reduced by your fault percentage
• There’s no threshold that bars recovery (unlike modified comparative fault states)

Example: If you’re awarded $100,000 but found 30% at fault, you’ll receive $70,000.

How Comparative Fault Works: The Process

Step 1: Determining Each Party’s Fault Percentage

When you file a personal injury claim, several parties evaluate the evidence to assign fault:

During Insurance Negotiations:

• Adjusters review police reports, witness statements, photos, and videos
• Accident reconstruction experts may analyze the scene
• Medical records show injury patterns and treatment compliance

In Court:

• Judges provide jury instructions on negligence law
• Jurors answer specific questions about each party’s conduct
• The verdict form includes fault percentages that must total 100%

Step 2: Calculating Total Damages

Damages in California personal injury cases include:

• Economic damages: Medical bills, future care costs, lost wages, property damage
• Non-economic damages: Pain and suffering, emotional distress, loss of enjoyment

Step 3: Applying the Fault Reduction

Once total damages are determined, your recovery is reduced by your fault percentage using this simple formula:

Your Recovery = Total Damages × (100% – Your Fault %)

Real-World Examples of Comparative Fault

Car Accident with Shared Responsibility

Scenario: Driver A is speeding at 55 mph in a 40 mph zone. Driver B makes an unsafe left turn without yielding.

Fault Assignment:

• Driver A: 40% (speeding reduced reaction time)
• Driver B: 60% (violated right-of-way)

Result: If Driver A’s damages are $50,000, recovery is $30,000 ($50,000 × 60%).

Slip and Fall at a Store

Scenario: A grocery store fails to clean up a spill for 30 minutes. A customer is texting while walking and doesn’t notice warning signs.

Fault Assignment:

• Store: 70% (failed to maintain safe premises)
• Customer: 30% (distracted, ignored warnings)

Result: Customer recovers $28,000 of $40,000 in damages.

Who Decides Your Fault Percentage?

Insurance Adjusters vs. Juries

Insurance Claims: Insurance adjusters consider multiple factors when assigning fault, including:

• Police reports and accident investigations
• Traffic laws and safety violations
• Witness credibility
• Physical evidence (skid marks, vehicle damage, surveillance footage)
• Expert opinions

Court Trials: If settlement negotiations fail, a jury determines fault by answering questions such as:

1. Was the defendant negligent?
2. Was the plaintiff negligent?
3. Did each party’s negligence contribute to the harm?
4. What percentage of fault belongs to each party?
5. What is the total amount of damages?

Comparative Fault vs. Contributory Negligence

California’s system is more favorable to injured parties than the older “contributory negligence” rule still used in a few states:

What Factors Increase Your Fault Percentage?

Common Defense Arguments

Insurance companies and defendants often argue you share fault based on:

Inattention:

• Using your phone while driving or walking
• Not watching where you’re going
• Wearing headphones in traffic

Safety Violations:

• Speeding or reckless driving
• Jaywalking or ignoring crosswalks
• Disregarding warning signs

Failure to Mitigate Damages:

• Delaying medical treatment
• Not following doctor’s orders
• Ignoring physical therapy recommendations

Open and Obvious Dangers:

• Walking into clearly visible hazards
• Ignoring obvious risks

How These Defenses Affect Your Case

These arguments don’t necessarily defeat your claim—they may just reduce your recovery. Your personal injury attorney will counter by demonstrating:

• The defendant’s conduct was the primary cause
• Your actions were reasonable under the circumstances
• Any mistakes you made contributed minimally to the harm

Multiple Parties: How Fault Is Divided

When Several People or Companies Share Responsibility

Accidents often involve multiple defendants:

• Multi-vehicle collisions with several at-fault drivers
• Product liability cases involving manufacturers, distributors, and retailers
• Workplace accidents with multiple contractors

California’s Joint and Several Liability:

• Economic damages: Each defendant may be responsible for the full amount (though they can seek reimbursement from others)
• Non-economic damages: Each defendant typically pays only their percentage

This affects settlement strategy, especially when defendants have different insurance limits.

Evidence That Reduces Your Fault Percentage

Critical Documentation

Strong evidence can significantly lower your assigned fault:

Immediate Scene Evidence:

• Photographs and videos from multiple angles
• Witness contact information
• Police or incident reports

Medical Documentation:

• Prompt medical treatment records
• Proof of following treatment plans
• Doctor’s notes on injury causation

Technical Evidence:

• Vehicle “black box” data
• Surveillance footage
• Traffic light timing records
• Road design documentation
• Cell phone records (proving you weren’t texting)

Property Evidence:

• Maintenance logs for hazardous conditions
• Company safety policies
• Training records

Special Situations in Comparative Fault Cases

Children and Minors

Children are judged by a different standard—what a reasonably careful child of the same age, experience, and intelligence would do. This often results in lower fault percentages for young injured parties.

Assumption of Risk

In sports and recreational activities, participants may “assume the risk” of inherent dangers. This can sometimes reduce or bar recovery for those particular risks, depending on the circumstances.

Product Liability Cases

Even when a product is defective, your damages may be reduced if you misused the product in a way that contributed to your injury—unless the misuse was reasonably foreseeable by the manufacturer.

Product defect claims explained

Seatbelts and Safety Equipment

Failing to wear a seatbelt or helmet can reduce your damages if it made your injuries worse. Expert testimony typically demonstrates how much the lack of protection contributed to the harm.

Alcohol or Drug Impairment

Intoxication heavily influences fault assignment. Objective evidence like blood alcohol tests or toxicology reports carries significant weight with juries.

How Comparative Fault Affects Settlement Negotiations

Why Fault Percentages Matter in Settlements

Much of settlement negotiation centers on fault because it directly impacts the payout:

What’s Negotiated:

• The facts showing each party’s actions
• Strength of evidence (photos, videos, expert opinions)
• Witness credibility
• Medical causation
• Whether you worsened your condition

Insurance Company Tactics:

• Initial offers often assign high fault percentages to injured parties
• Adjusters scrutinize medical records for treatment gaps
• Recorded statements can be used to argue greater fault

Your Attorney’s Strategy:

• Present compelling evidence of the defendant’s primary responsibility
• Document your reasonable conduct
• Show minor contribution of any mistakes you made
• Demonstrate consistent medical treatment

Common Myths About Comparative Fault

Myth 1: “If I was partly at fault, I can’t recover anything”

Reality: In California, you can recover even if you were 90% at fault. Your award is simply reduced by your percentage.

Myth 2: “Two-party accidents are always 50/50”

Reality: Fault percentages depend on the specific facts. One party can be 10%, 75%, or any percentage between 0-100%.

Myth 3: “Insurance companies decide the final percentages”

Reality: Insurers take a position, but if you disagree, a judge or jury makes the final determination.

Myth 4: “Apologizing at the scene admits fault”

Reality: California’s pure comparative fault means you can still recover. However, it’s best to stick to facts.

Myth 5: “Comparative fault only applies to car crashes”

Reality: It applies to slip and falls, dog bites, product injuries, medical malpractice, and virtually all negligence claims.

Time Limits: Don’t Wait Too Long

California Statute of Limitations

Comparative fault affects how much you recover—not whether you can file. However, you must file your claim within specific deadlines:

General Personal Injury: 2 years from the date of injury

Government Entity Claims: 6 months to file an administrative claim, then additional time to sue if denied

Discovery Rule: In some cases, the clock starts when you discover the injury

Minors: Special rules may extend deadlines for injured children

Missing a deadline can bar your claim entirely, regardless of fault percentages. Contact an attorney immediately to protect your rights.
