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 Montana 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 Montana?

You have 3 years from Date of injury; delayed if injury and causal relationship not reasonably discoverable at time of act or omission, under Mont. Code Ann. § 27-2-204(1).

Can I still sue after 3 years in Montana?

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 Montana?

Yes. Clock starts when plaintiff discovers or reasonably should have discovered injury and its causal relationship to the act or omission (Mont. Code Ann. § 27-2-102(3))

What if the victim was a minor?

Montana 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 before suing state or local government; may file suit after claim denied or 120 days pass from notice (Mont. Code Ann. § 2-9-301)
