The deadline to file in New Hampshire

New Hampshire generally gives injured people 3 years from the date of a crash to file a personal-injury lawsuit. Miss it and the court will almost always refuse the case, no matter how strong it is. The clock can run differently for claims involving a government vehicle, an injured minor, or a death, so the single most important early step is to confirm your actual deadline.

How New Hampshire handles fault

New Hampshire uses modified comparative fault: you can recover as long as your share of fault stays below the state's bar (generally around half), with compensation reduced by your percentage.

No-fault vs. at-fault in New Hampshire

New Hampshire is an at-fault (tort) state. The driver who caused the crash — and their insurer — is responsible for the resulting damages, so establishing fault is central to your claim.

Minimum insurance in New Hampshire

Drivers in New Hampshire must carry at least $25,000 / $50,000 in liability coverage. Those minimums are often far below what a serious injury actually costs, which is why your own uninsured/underinsured motorist coverage can end up being the coverage that matters most.
