Comparative Negligence by State: Pure, Modified & Contributory

Comparative negligence is the rule that reduces what you can recover after an accident by your own share of the blame. If you were 20% at fault for a crash, you recover 80% of your damages. How far that goes depends on which version of the rule your state follows.

The short version:

• Pure comparative negligence: you can recover something even if you were mostly at fault.
• Modified comparative negligence: you recover nothing once your fault reaches 50% or 51%, depending on the state. Most states use this.
• Contributory negligence: you recover nothing if you were at fault at all. Only four states and the District of Columbia use it.
• The state-by-state table below shows which rule applies where, including the 2026 changes in Louisiana and New York.
• The percentages are assigned by a jury, or negotiated with insurers, based on the evidence.

This is general information, not legal advice. The rule that applies is the law of the state where the accident happened.

How it works

After an accident with more than one person at fault, each is assigned a percentage of responsibility. Your damages, meaning medical bills, lost income, pain and suffering, and so on, are added up, then reduced by your percentage.

Say your damages are $100,000 and you are found 30% at fault. Under comparative negligence you recover $70,000.

The three systems side by side

The table shows what a person with $100,000 in damages would recover at different levels of their own fault.

Pure comparative negligence

You can recover whatever share was not your fault, even if you were 99% responsible. Ten states follow this rule, including California and, for most cases, New York.

Modified comparative negligence

You recover a reduced amount up to a cut-off, and nothing beyond it. There are two versions:

• 50% bar: you are barred if you were 50% or more at fault.
• 51% bar: you are barred if you were 51% or more at fault. At exactly 50%, you can still recover half.

Most states use one of these two: ten apply the 50% bar and twenty-five the 51% bar. The difference only matters when fault is split evenly, but that is a common finding. Florida moved from the pure rule to a modified rule in 2023, and Louisiana did the same for accidents from 1 January 2026.

Contributory negligence

Under contributory negligence, any fault on your part, even 1%, bars recovery completely. Only Alabama, Maryland, North Carolina, Virginia, and the District of Columbia still follow it. Courts in those places recognise some exceptions, but the basic rule is harsh.

Which rule each state uses

The table groups every state by the rule it applies to ordinary negligence claims. It follows the 50-state chart kept by the law firm Matthiesen, Wickert & Lehrer, which was last updated on 10 June 2026 and cites the statute or court decision behind each entry.

Several entries come with a condition, and the chart records each one:

• Louisiana applies the 51% bar to accidents on or after 1 January 2026. Older claims still fall under the pure rule.
• New York remains a pure comparative state in general. The chart reports a 51% bar for motor vehicle injury actions under the no-fault law that are started on or after 26 May 2026, under a 2026 session law. If your New York crash claim is recent, confirm which rule applies.
• Florida has used the 51% bar for negligence suits since 24 March 2023, except medical malpractice, which stays under the pure rule.
• The District of Columbia keeps contributory negligence but applies a 51% bar to pedestrians, cyclists, and other non-motorised road users hit by vehicles.
• Indiana applies contributory negligence to claims against government bodies and their employees.
• West Virginia uses the 51% bar for claims arising since 25 May 2015; older claims fall under a 50% bar.
• South Dakota stands alone. An injured person recovers only if their own negligence was slight compared with the other side’s.

Is my state a pure comparative negligence state?

Only the ten states in the first row are. Missouri is one of them, by a 1983 decision of its supreme court instead of a statute. Florida and Louisiana used to be on the list and are not any more. If your state is in the second or third row, your claim ends once your share of fault reaches the bar.

How fault percentages are decided

There is no formula. In a lawsuit, a jury hears the evidence and assigns percentages. In an insurance claim, adjusters propose a split and the two sides negotiate. The evidence that moves the numbers includes:

• the police report and any traffic citations;
• photos, dashcam and surveillance video;
• witness statements;
• vehicle damage and accident reconstruction;
• in truck cases, electronic logging data and hours-of-service records.

Common arguments for putting some fault on an injured person include speeding, distraction, not wearing a seat belt, and failing to avoid a hazard they could have seen. Some states limit how seat-belt evidence can be used.

Why it matters in a settlement

Insurers use comparative fault as a negotiating tool. An adjuster who says you were 30% at fault is proposing a 30% cut to your claim, and in a modified state, pushing you past the cut-off would end the claim entirely. An early statement that sounds like an admission can be used this way, which is one reason to be careful about recorded statements.

When several defendants share fault

When more than one defendant is responsible, states differ on whether each pays only its own share or whether one can be made to pay the whole amount under joint and several liability. This matters when one defendant has little insurance, and it comes up often in crashes involving commercial trucks, where several parties can be liable.

Frequently asked questions

Can I recover damages if I was partly at fault?

In most states, yes, with the amount reduced by your share of fault. In a modified state you must be below the 50% or 51% cut-off. In a contributory negligence jurisdiction, any fault bars recovery.

What is the difference between comparative and contributory negligence?

Comparative negligence reduces your recovery in proportion to your fault. Contributory negligence eliminates it entirely if you were at fault at all.

What is the difference between the 50% and 51% bar rules?

Under the 50% bar you get nothing at 50% fault. Under the 51% bar you can still recover at exactly 50%.

Who decides how much I was at fault?

A jury if the case goes to trial. Otherwise the split is negotiated between you, or your lawyer, and the insurers.

Which states still use contributory negligence?

Alabama, Maryland, North Carolina, and Virginia, plus the District of Columbia. In D.C. the rule is relaxed for pedestrians and cyclists, who are barred only if they were more than half at fault.

Does comparative negligence apply outside car accidents?

Yes. It applies to most negligence claims, including slip-and-fall and other premises claims, product injuries, dog bites handled under negligence rules, and other accidents.
