Comparative negligence in New Jersey and New York

Insurance companies often argue that the injured person was partly to blame. You were going a little fast, you were looking at your phone, you should have seen the wet floor. The goal is to lower what they pay, or to avoid paying at all.

The legal name for shared fault is comparative negligence. Both New Jersey and New York use it, which means your own share of fault usually reduces your recovery rather than wiping it out. But the two states apply it very differently, and the difference can decide whether a case is worth anything.

This guide explains the rules in plain terms and walks through examples. The numbers below are hypothetical and are only meant to show how the math works. They do not predict what any case is worth.

What comparative negligence means

Negligence is a failure to use reasonable care. In a comparative negligence system, the jury looks at everyone whose carelessness helped cause the harm, including the injured person, and assigns each a percentage of fault. Your damages are then reduced by your own percentage.

So if a jury decides your total damages are $100,000 and that you were 20 percent at fault, your recovery is reduced to $80,000. That part works the same way in both states.¹⁵ The states part ways on what happens when your share gets large.

The New Jersey rule and the more-than-50-percent bar

New Jersey uses what is often called modified comparative negligence. Your own fault does not bar recovery as long as it was not greater than the fault of the person you are suing, or the combined fault of all the people you are suing. Whatever you recover is reduced by your percentage.¹

That means a plaintiff found exactly 50 percent at fault still recovers half. A plaintiff found 51 percent at fault recovers nothing at all. Because the comparison is against the defendants’ combined fault, a plaintiff who is 40 percent at fault can recover even if no single defendant was more than 40 percent at fault, so long as together they were 60 percent.¹

The New York rule, and the 2026 change for car cases

For most kinds of claims, New York uses pure comparative fault. Under CPLR 1411, your own culpable conduct, which includes ordinary carelessness and what the law calls assumption of risk, does not bar recovery. Your damages are reduced in proportion to your share of the fault.⁵ A New York plaintiff found 70 percent at fault in a fall at a store can still recover 30 percent of the damages.

In 2026 New York carved out car cases. For personal injury actions governed by the no-fault law (Article 51 of the Insurance Law) that are started on or after May 26, 2026, you recover nothing if your share of fault is greater than the share of the person you are suing, or the combined share of everyone you are suing. If your share is not greater, your damages are still reduced by your percentage.¹⁰ That puts New York car cases much closer to the New Jersey rule.

Worked examples

Each example assumes a jury finds total damages of $100,000. These are hypothetical figures used only to show the math.

The first three rows come out the same everywhere. The difference appears once the injured person’s share passes 50 percent. In New Jersey the claim is barred.¹ In most New York cases it continues at a reduced value.⁵ In a New York car case governed by the no-fault law and filed on or after May 26, 2026, it is barred, just as in New Jersey.¹⁰

When more than one defendant is at fault

Many accidents involve more than one responsible party, such as two drivers, or a property owner and a maintenance contractor. The next question is how much each defendant must actually pay, which matters most when one of them has little or no insurance.

New Jersey and the 60 percent line

The rule that lets you collect the whole amount from one defendant, even though others share the blame, is called joint and several liability. In New Jersey you can recover the full amount of your damages from any defendant the jury finds 60 percent or more responsible. A defendant found less than 60 percent responsible pays only its own percentage. A defendant who pays more than its share can seek contribution from the others.²

Here is a hypothetical. Damages are $100,000, you are not at fault, Driver A is 70 percent at fault and Driver B is 30 percent at fault. You can collect the full $100,000 from Driver A, who can then pursue Driver B for B’s share.²

Change the numbers so that Driver A is 55 percent and Driver B is 45 percent. Now neither reached 60 percent. Driver A owes $55,000 and Driver B owes $45,000. If Driver B cannot pay, you cannot collect B’s share from Driver A.²

New York and CPLR Article 16

New York takes a different approach. When a defendant is found 50 percent or less at fault, its liability for non-economic loss, meaning pain and suffering and similar losses, is limited to its own share. Its liability for economic loss, like medical bills and lost wages, is not limited by this rule.⁶ The rule also covers claims against New York State.⁶

Important exceptions apply. The limit does not protect anyone held liable because of the use, operation or ownership of a motor vehicle or motorcycle. It also does not protect a defendant who acted with reckless disregard for the safety of others, a defendant held liable for an intentional act, or parties who acted knowingly and intentionally in concert.⁷ It does not change the rules for liability based on a non-delegable duty or for an employer’s responsibility for its employee.⁷

Here is a hypothetical. In a fall at a store, damages are $60,000 in economic loss and $140,000 in non-economic loss. The store owner is 70 percent at fault and its cleaning contractor is 30 percent at fault. The contractor’s share of the non-economic loss is limited to 30 percent, or $42,000, but it can still be responsible for the full $60,000 in economic loss.⁶ If the same percentages came from a two-car crash, the motor vehicle exception would apply and the 30 percent driver could be responsible for the full amount.⁷

The seatbelt defense

Defendants in car crash cases often argue that the injured person was not wearing a seatbelt. Neither state treats that as a complete bar to recovery, and in both states the defendant carries the burden of proving it made the injuries worse.

In New Jersey

In Waterson v. General Motors Corp., the New Jersey Supreme Court rejected the idea that not wearing a seatbelt should defeat a claim and created a separate method for handling it. The defendant must prove that a belt was available, that not using it was negligent, and that the failure increased the extent or severity of the injuries, which usually requires expert testimony.³⁴

If the defendant proves those points, the jury separates out the “seatbelt damages,” meaning the injuries a belt would have prevented. Only that portion receives the extra reduction for not wearing the belt. Damages for injuries that would have happened anyway are reduced only by any fault you had in causing the crash itself.³⁴

In New York

In Spier v. Barker, New York’s highest court held that not wearing a seatbelt may be considered only on damages, never on who caused the accident. The defendant must prove that not wearing the belt increased the injuries, and the issue goes to the jury only with competent evidence of that connection.⁸ New York’s seatbelt statute now says the same thing. Not wearing a belt is inadmissible on liability but may be offered to reduce damages, and only if the defendant pleaded it as an affirmative defense.⁹

What this means for your claim

1. Do not admit fault at the scene or in a recorded statement. Describe what happened and let the evidence speak.
2. Preserve evidence of how the accident happened, including photos, video, the names of witnesses and the police report.
3. Expect the insurer to argue that you share the blame, and do not accept its percentage as the final word.
4. Identify every party who may share responsibility, along with each one’s insurance, since the multi-defendant rules can determine who actually pays.
5. If your accident happened in one state and you live in the other, see our guide to cross-border accidents, because the state whose law applies can change these rules.

Our pages on car accidents, premises liability and pedestrian and bicycle accidents explain how fault is commonly argued in those cases.
