Total loss rule: repairs cost 75% or more of the car's actual cash value. Deadline to file an injury lawsuit: 3 years.

Claim-handling deadlines in New Hampshire

Acknowledge your claim	10 working days
Accept or deny it	30 calendar days after notice of claim
Pay after agreement	5 working days after agreement

Rule: N.H. Code Admin. R. Ins 1002.03, 1002.04(b), 1002.05(a)-(f).

The decision clock usually starts once the insurer has the proof of loss it asked for, not on the day of the accident. Ask the adjuster in writing what they still need, and keep a dated log of everything you send.

If the insurer misses a deadline or lowballs you

Send a short written follow-up that names the deadline and asks for a decision by a specific date.

If you have to sue the other driver in New Hampshire

Most claims settle without a lawsuit, but these rules decide how much leverage you have when you claim against the at-fault driver's insurer.

If you were partly at fault	Modified comparative fault (51% bar)
Deadline to sue for injuries	3 years
Deadline to sue for car damage	3 years

Your recovery is cut by your share of the fault, and you get nothing if you are more at fault than the other side (51% or more).

The lawsuit deadline (statute of limitations) usually runs from the accident date, and an open insurance claim does not pause it.

Rules: RSA 507:7-d; RSA 508:4.
