Comparative vs. contributory negligence: how fault splits a claim
Short answer
- Both rules decide what happens when the injured person was partly to blame.
- Under contributory negligence, used in 4 states and the District of Columbia, any fault at all can bar recovery.
- Under comparative negligence, used everywhere else, recovery is cut by your share.
- In New Jersey, you recover nothing only above 50%.

What each rule pays at your share of fault
Pick a share of fault. Each row shows what the same sample claim comes to under one of the four rules. It can't tell you your share, or what your claim is worth.

An example of the arithmetic, not a value for any claim. NJ marks New Jersey's rule. In a trial, a jury decides the shares of fault; in a settlement, they're negotiated.
The four rules
There are four common rules for a claim where the injured person shares the blame. Cornell's Legal Information Institute says most states follow one of the two modified rules.
Any share of the fault, even a small one, can bar the whole claim. Cornell's Legal Information Institute names 4 states that still use it, Alabama, Maryland, North Carolina and Virginia, plus the District of Columbia.

A fault rule only comes into play once someone was negligent: they failed to use the care a reasonable person would have used in the same situation. You'll often see four elements listed: duty, breach, causation and harm. Cornell's Legal Information Institute lists five, because it splits causation in two.
- DutyThe person you're claiming against owed you a legal duty. In New Jersey, for example, the law tells drivers not to follow another vehicle more closely than is reasonable and prudent.Source: Cornell Law School, Legal Information Institute, Wex: negligence; Model Civil Jury Charge 5.30D, Violation of Traffic Act (N.J.S.A. 39:4-89)
- BreachThey didn't meet it: they acted with less care than a reasonable person would have in the same circumstances.Source: Cornell Law School, Legal Information Institute, Wex: negligence
- Cause in factThe harm wouldn't have happened but for what they did.Source: Cornell Law School, Legal Information Institute, Wex: negligence
- Proximate causeThe harm is close enough to what they did for the law to hold them responsible. One way courts judge it is whether the harm was foreseeable.Source: Cornell Law School, Legal Information Institute, Wex: negligence
- HarmYou were actually hurt. Typically that means an injury to your body or damage to your property.Source: Cornell Law School, Legal Information Institute, Wex: negligence
NJNew Jersey's rule
New Jersey uses the modified rule with the line at more than half. Its statute works in three steps.
- The jury puts a percentage on everyoneIn a trial, the jury finds each party's share of the negligence or fault as a percentage.Source: N.J.S.A. 2A:15-5.1; N.J.S.A. 2A:15-5.2
- Your share cuts what you recoverYour damages are reduced by the percentage of the fault put on you.Source: N.J.S.A. 2A:15-5.1; N.J.S.A. 2A:15-5.2
- More than 50%, and you recover nothingYou recover only if your negligence was not greater than the other side's. When you sue more than one party, yours is weighed against all of theirs combined.Source: N.J.S.A. 2A:15-5.1; N.J.S.A. 2A:15-5.2
Rules change: Florida's newer line
A state can change its rule, so an old summary can be wrong. Florida's statute was last amended in 2023, and as printed for 2026 it draws the same line New Jersey does.
- Your share still cuts the awardIn a negligence action, the claimant's own fault reduces the amount awarded in proportion.Source: Fla. Stat. 768.81(2), (6)
- More than 50%, and you recover nothingA party found greater than 50% at fault for their own harm may not recover any damages. The statute leaves medical negligence claims out of that line.Source: Fla. Stat. 768.81(2), (6)
The last clear chance exception
Contributory negligence has a well-known exception, the last clear chance doctrine: a negligent plaintiff can still recover if the defendant was the only one who could have prevented the harm.

Questions people ask
What is the difference between contributory and comparative negligence?
Under contributory negligence, any fault of your own can bar your whole claim. Under comparative negligence, your recovery is cut by your share of the fault, and under the modified versions it stops past a line.
What are the four elements of negligence?
Duty, breach, causation and harm: someone owed you a duty, failed to meet it, that failure caused your harm, and you were actually hurt. Cornell's Legal Information Institute splits causation into cause in fact and proximate cause, for five.
Which states use contributory negligence?
Cornell's Legal Information Institute names 4: Alabama, Maryland, North Carolina and Virginia, plus the District of Columbia. Every other state uses a comparative rule.
What is pure comparative fault?
Your recovery is cut by your share of the fault, at any share. Someone found mostly at fault can still recover the part of their damages that wasn't their fault.
What is modified comparative negligence?
Your recovery is cut by your share, until your share reaches a line. Under the 50% bar you recover nothing at 50% or more; under the 51% bar, at 51% or more.
Does New Jersey use comparative negligence?
Yes, a modified version. Your damages are cut by your share of the fault, and you recover nothing if your negligence was greater than the other side's, or than everyone you sued combined.
Can you recover if you were 50% at fault?
It depends on the state's rule. Under a 51% bar, like New Jersey's, you recover half. Under a 50% bar or contributory negligence, nothing. Under pure comparative negligence, half.
