Dismissal, almost without exception
If a personal injury lawsuit is filed in Michigan after the applicable statute of limitations has run — the general three-year deadline under MCL 600.5805(2), or a shorter deadline like the 120-day highway defect notice — 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 Michigan 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 distinctive risk: Michigan's "borrowed" wrongful death deadline
Because Michigan's Wrongful Death Act has no fixed deadline of its own — it borrows whatever period applies to the underlying cause of action — there's a real, specific risk of assuming a single, flat wrongful death deadline applies universally. A family that doesn't realize their loved one's death resulted from medical malpractice, rather than ordinary negligence, could easily miscalculate by a full year, since the malpractice-based deadline runs shorter. See our guide to Michigan's wrongful death timing rules for exactly how this works.
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 Michigan's rules genuinely differ depending on the type of claim and the cause of a death, the only reliable way to know where things actually stand is to confirm the exact date with a licensed Michigan attorney as early as possible.
