The 91-Day Summons Window in Michigan: Serving Before the Clock Runs Out

A Michigan summons expires 91 days after the court issues it, under MCR 2.102. The defendant has to be served inside that window. Miss it and the filing does not simply pause; the plaintiff has to go back and ask the court for a new summons before anyone can try again.

The clock starts at issue, not at filing

The date that matters is the one the court stamps on the summons. Everything before that, drafting, review, the back and forth over an address, costs nothing against the 91 days. Everything after it does. That distinction sounds obvious and is still the most common reason a file arrives with far less runway than anyone assumed: the summons was issued three weeks before it reached the person who had to act on it.

Ninety-one days is not ninety-one attempts

The window is calendar days, and the calendar is not on anyone's side. Weekends and holidays sit inside it. So does the stretch where a defendant works nights and is simply not home during the hours anyone would reasonably knock. A window that reads as three months on paper often holds far fewer genuinely usable attempt slots than that.

What quietly consumes the runway

• A stale address. The single biggest consumer of days. Attempts at an address the defendant left months ago are not slow progress, they are no progress, and they look identical to progress until somebody checks.
• Access you cannot plan around. Gated communities, secured lobbies, rural properties with a long private drive. Each one can turn a fifteen-minute stop into a repeat visit at a different hour.
• Waiting to escalate. The alternatives in the rules exist for a reason, and reaching for one on day 80 leaves no margin if the court wants more detail before it will allow it.

What happens when the window closes

An expired summons does not end the case, but it does mean nobody can serve on it. The plaintiff requests a new one and the clock restarts. What that really costs is elapsed time on a matter that was presumably filed because time mattered, plus the awkward conversation about why three months produced no completed service.

Documented attempts are what protects the record

When the window gets tight the question stops being did you try and becomes can you show what you tried. Dates, times, addresses, and what was observed at each one. Attempts recorded that way are the difference between a file that supports a request for an alternative method and a file that only says nobody answered.

That is why every attempt gets documented and not only the successful one. The completed serve comes back as a notarized affidavit of service. The unsuccessful attempts are what make it credible, because they show the serve was earned rather than lucky.

Planning service around the window

Two habits do most of the work. Confirm the address is current before the first attempt rather than after the third, and start early enough that the alternatives in the rules are still genuinely available rather than argued under pressure.
