Dismissal, almost without exception
If a personal injury lawsuit is filed in Montana after the applicable statute of limitations has run — the general three-year deadline under MCA § 27-2-204, or the shorter two-year rule for claims like libel or assault — the court will almost always dismiss the case as time-barred. This happens regardless of how strong the underlying claim actually is or how serious the injury turned out to be.
Courts apply these deadlines strictly
Statutes of limitations exist specifically to create a firm, predictable cutoff, and Montana courts generally enforce them that way. Being close to the deadline, or having a sympathetic reason for the delay that doesn't fit a recognized legal exception, isn't on its own a basis for a court to excuse a late filing.
A genuinely real risk around Montana's homicide carve-out
Because Montana's wrongful death statute carries two very different deadlines depending on the cause of death — a standard three years, or a genuinely longer 10 years specifically when the death resulted from a homicide — there's a real risk of miscalculation in either direction. A family might wrongly assume the shorter three-year rule has already run, not realizing the 10-year window actually applies to their situation. Confirming which rule genuinely governs a specific wrongful death claim is worth doing early and carefully.
Negotiations end along with the legal leverage behind them
One of the more painful practical consequences: once the statute of limitations has actually run, an insurance company has no legal obligation to keep negotiating, to make any offer, or to pay anything at all — even if settlement talks were active and seemingly productive right up until the deadline passed.
If there's any doubt at all
Because the consequence of missing a deadline is generally permanent, and because Montana's rules genuinely differ depending on the type of claim and, for wrongful death, the cause of death, the only reliable way to know where things actually stand is to confirm the exact date with a licensed Montana attorney as early as possible.
