Michigan Car Accident Lawsuit Deadline: The 3-Year Clock

Your adjuster is being so nice lately. Returning calls, sounding sympathetic, asking for “just one more” medical record before they can “finalize the offer.” There’s a reason, and it has a date on it: Michigan’s deadline to file a car accident lawsuit.

How long do you have to sue after a Michigan car crash?

Three years from the date of the crash. Under MCL 600.5805(2), most Michigan personal injury lawsuits, including car accident claims against an at-fault driver, must be filed within three years. Not three years from when settlement talks broke down. Not three years from when the insurance company stopped returning calls. Three years from the moment of impact, because the claim accrues when the injury happens (MCL 600.5827).

Miss it by one day and the case is almost always gone. No exceptions for “but we were close to settling.” No exceptions for “my lawyer said they had it covered.” The courthouse door closes.

Does negotiating with the insurer stop the clock?

No. Only a complaint filed in court stops it. This is the most common way strong cases die.

Insurance companies have calendars too. Adjusters know your deadline better than you do. And the oldest move in the playbook is to look reasonable (responsive, empathetic, “just a few more weeks”) until the clock runs out.

Once you’re past the three-year mark without a lawsuit on file, the adjuster’s calculation changes. The offer they were dangling disappears, because the claim can no longer be enforced.

What should your lawyer be doing by month 24?

By the end of the second year, a case that hasn’t settled should be headed into a lawsuit, or already in one. A typical rhythm for a Michigan auto injury case looks roughly like this:

• Months 0–6: Treatment, medical records, liability investigation. (Here’s why Michigan PI cases take so long in this stretch.)
• Months 6–12: Demand package to the at-fault insurer.
• Months 12–18: Negotiation. Real money moves, or it doesn’t.
• Months 18–24: Lawsuit filed if the number isn’t there. Filed, not threatened.

Lawsuits are not a last-resort nuclear option. They’re the normal next step when an insurer won’t pay a fair number voluntarily. If it’s month 22 and nobody has mentioned filing suit, either they don’t intend to file, or they forgot. For what the full case timeline looks like after suit is filed, and how to tell a slow case from a stalled one, see what a stalled Michigan PI case actually means.

Are there exceptions that give you more time?

A few, and they rarely help an adult driver in an ordinary crash.

Minors. Under MCL 600.5851, someone hurt before age 18 gets at least one year after turning 18 to file, even if the three years have otherwise run. This does not help an adult.

Defendants outside Michigan. Tolling (pausing the clock) for an absent defendant is narrow. It is not something a careful lawyer relies on.

“I didn’t realize I was hurt.” Auto injury claims don’t get a general discovery rule. The Michigan Supreme Court rejected the common-law discovery rule in Trentadue v Buckler Automatic Lawn Sprinkler Co, 479 Mich 378 (2007). The clock starts on the crash date even if the full extent of your injury shows up six months later.

Different defendants, different clocks. Some claims run shorter, not longer. If a city bus, a government truck or a road defect was involved, written notice can be due in as little as 120 days (MCL 691.1404). See the 120-day notice rule for government claims. Medical malpractice has its own 2-year rule; see Michigan’s med-mal deadline.

What is the 1-year PIP clock?

Your no-fault PIP benefits run on separate one-year rules, and they start running right away. Under MCL 500.3145:

• Notice within 1 year. You must give your own auto insurer written notice of the injury within one year of the crash (or the insurer must have already paid PIP benefits). Otherwise a PIP lawsuit is barred.
• One-year-back rule. If you later have to sue your insurer over unpaid bills or wage loss, you generally can recover only losses incurred within the one year before the lawsuit was filed. That period is paused from the date you submit a specific claim until the insurer formally denies it, as long as you pursue the claim diligently.

So an unpaid MRI bill that was never submitted, and that nobody sued over, can age out. This is why waiting to “let things develop” before getting help is dangerous in Michigan.

What if you’re within 90 days of the deadline?

Act the same day. Many firms decline cases this close to the deadline because the risk of missing it is high. That doesn’t mean you’re out of options. It means you need to call today, give the crash date on the first call, and keep calling if the first firm hedges.

If you already have a lawyer who hasn’t filed suit and your deadline is 90 days out, that’s a conversation for this week, not next month. You have the right to change lawyers at any time, even mid-case. Here’s what switching actually costs.

The question to ask, right now

Count back from today to the day of your crash. If it’s more than 24 months and nobody has mentioned filing a lawsuit, you have one job this week:

Ask your lawyer, in writing: “What is the filing deadline on my case, and what is the plan for filing suit before that date?”

Their answer, or their silence, will tell you a lot. If it doesn’t add up, get a free second opinion on your deadline.
