Comparative Negligence Calculator by State
If you were partly at fault for your own injury, your state's rule decides whether that reduces what you can recover — or wipes it out entirely. Enter your damages and your fault percentage below to see the actual math for your state.
Not legal advice — and missing this deadline can end your case. These are general filing deadlines under each state's statute. Your actual deadline can be shorter or longer: many states toll the clock for minors, apply a "discovery rule" when an injury isn't immediately obvious, or give you far less time to sue a government agency. Confirm your specific deadline with a licensed attorney in your state before relying on any date here.

About this data: Each period and citation above was extracted by hand from the actual statute text in our
statutes database
(sourced from official government publishers via the
Open US Law dataset, Vaquill AI, CC BY 4.0)
and cross-checked against that text, rather than copied from another site's chart — where we found a state's citation didn't match what's commonly cited elsewhere (a recent law change, for example), we used the current statute. Where a state's source text isn't in our database yet, we say so instead of linking to something we haven't verified.
