Car accident claim in New York

New York applies modified comparative fault to car accident cases, allowing partial recovery even when the claimant bears significant responsibility, but not when the claimant bears most of it. The gap between what a skilled attorney negotiates on fault and what a passive one accepts can exceed the contingency fee itself. For actions commenced on or after May 26, 2026, CPLR 1411(b) bars recovery in personal injury actions subject to New York's no-fault law (Insurance Law article 51) when your share of fault is greater than the combined fault of those you sue.

How Modified Comparative Fault Turns Every Percentage Point Into Money

Under New York law, comparative fault reduces your compensation by whatever fault share a jury or adjuster assigns you, with a cutoff above 50%. A driver found 45% at fault still recovers 55% of total damages. That sliding scale makes your attorney's skill at contesting fault allocation one of the largest financial variables in your case. On a contingency basis, the attorney's fee is a percentage of your net recovery -- which means reducing your fault from 40% to 20% increases the lawyer's own earnings alongside yours. Use this alignment during consultations. Ask each candidate what percentage of their car accident cases involved a disputed fault allocation and how those disputes were resolved. Attorneys who regularly contest fault bring a different preparation level than those who negotiate only on damage values.

Reducing Your Fault Percentage Through Strategic Evidence and Documentation

Building a low fault percentage in New York requires documentation that starts at the crash scene and continues through treatment. Photograph everything before vehicles are moved -- tire marks, debris patterns, traffic signals, and weather conditions. Obtain the names and phone numbers of every witness. Visit a medical provider within 24 hours even if you feel minor soreness, because untreated soft-tissue injuries become the adjuster's favorite tool for questioning causation. Once the evidence package is assembled, your lawyer should present a written counter to the insurer's fault finding supported by physical evidence and independent witness accounts. Do not accept the adjuster's first fault split as settled. In modified comparative states, moving your assessed fault down by even five points increases your net check proportionally, and on a contingency fee that increase benefits both you and your counsel.

A worked example with New York’s rule applied

Take a car accident claim with documented losses like these:

Under New York’s 51% bar, percentages behave like a cliff edge. At 50% fault this claim still pays $50,500; at 51% it pays $0. One percentage point moves $50,500, which is why the fault number in the adjuster's file is worth arguing about with evidence, not estimates.

Contingency Fee Math: What You Actually Keep After Legal Costs

Contingency fees typically run 33% before a lawsuit is filed and 40% after filing. On top of the attorney's percentage, case expenses -- filing fees, expert witness charges, medical record retrieval costs -- are deducted from the gross recovery. Your net check is what remains. Understanding this math before you sign the retainer agreement prevents surprises at settlement. Ask each prospective attorney whether expenses come off the top before or after the contingency percentage is calculated, because the order changes your take-home amount. Request a written breakdown showing how a hypothetical recovery would be divided. Attorneys who walk through the numbers openly are signaling confidence in their ability to produce a result worth your share. Those who deflect the question may not be.
