Estimate before the fault percentage is applied
See what your claim is worth before any reduction for shared fault.
Under comparative negligence, your settlement is reduced by the percentage of fault assigned to you. A $100,000 claim at 25 percent fault yields $75,000. In most states you can still recover as long as your fault share stays below 50 or 51 percent, depending on the state. In a small number of states, any fault at all bars recovery completely.
The three main systems
Pure comparative fault: You can recover regardless of how much fault is assigned to you, reduced proportionally. At 80 percent at fault on a $100,000 claim, you recover $20,000. Used in California, New York, Florida, and about a dozen other states.
Modified comparative fault (50% bar rule): Recovery is available as long as your fault share is 49 percent or less. At 50 percent, you recover nothing. Used in about 13 states.
Modified comparative fault (51% bar rule): Recovery is available as long as your fault share is 50 percent or less. At 51 percent, you recover nothing. This is the most common system, used in roughly 20 states.
Contributory negligence (pure bar): Any fault on your part, even 1 percent, eliminates all recovery. This applies in Alabama, Maryland, North Carolina, Virginia, and Washington D.C. It is the harshest rule for injured claimants, and adjusters in those states know it.
How fault is determined
In settlement negotiations, fault percentage comes from evidence: police reports, photographs, witness statements, accident reconstruction, and the applicable standard of care. Adjusters push your share upward to reduce their exposure. Your attorney pushes it back down. Whatever percentage is agreed upon reduces your recovery before any money changes hands.
Examples across systems
| System | Your fault | Claim value | Recovery |
|---|---|---|---|
| Pure comparative | 40% | $80,000 | $48,000 |
| Modified (51% bar) | 40% | $80,000 | $48,000 |
| Modified (51% bar) | 52% | $80,000 | $0 |
| Contributory negligence | 5% | $80,000 | $0 |
Practical impact on your settlement strategy
In a contributory negligence state, an insurer that can demonstrate any fault on your part may decline to pay anything. In comparative negligence states, the dispute is over the percentage, not all or nothing. Either way, building your evidence before submitting a demand is time well spent.
