When the Clock Starts

In New Hampshire, the limitations period for personal injury lawsuits generally begins on Date of act or omission; or date of discovery when injury and causal relationship were not and could not reasonably have been discovered at time of act. New Hampshire recognizes a discovery rule for this claim type: RSA § 508:4(I): when injury and causal relationship were not reasonably discoverable at time of act, clock runs from when plaintiff discovers or should have discovered them with reasonable diligence

What to Do Before the Deadline Runs

  1. Pin down your accrual date — the day the clock started — and calendar the deadline conservatively.
  2. Preserve evidence now: photos, records, witness contacts, bills. Evidence decays faster than deadlines.
  3. Send preservation/notice letters where required (especially for New Hampshire government defendants).
  4. If the deadline is inside 6 months, treat it as urgent — filing suit is the only reliable way to stop the clock.

Frequently Asked Questions

How long do I have to file a personal injury lawsuit in New Hampshire?

You have 3 years from Date of act or omission; or date of discovery when injury and causal relationship were not and could not reasonably have been discovered at time of act, under N.H. Rev. Stat. Ann. § 508:4.

Can I still sue after 3 years in New Hampshire?

Usually no — courts dismiss claims filed after the statute of limitations expires. Narrow exceptions (the discovery rule, tolling for minors, fraudulent concealment) can extend the deadline; whether one applies depends on your facts.

Does the discovery rule apply to personal injury lawsuits in New Hampshire?

Yes. RSA § 508:4(I): when injury and causal relationship were not reasonably discoverable at time of act, clock runs from when plaintiff discovers or should have discovered them with reasonable diligence

What if the victim was a minor?

New Hampshire generally pauses ("tolls") the deadline while the injured person is under 18, giving them time to file after reaching adulthood. Special limits can still apply, so check the statute.

Is the deadline different for claims against the government?

Written notice required to municipality within 60–180 days depending on entity type under RSA 507-B; then 3-year period applies
