How to Serve Divorce Papers in Michigan

After filing your divorce complaint, you have exactly 91 days to serve your spouse. Miss that deadline and the court dismisses your case — no extensions, no exceptions (unless you proactively file for one). Michigan's service rules under MCR 2.105 are strict about who can serve, how they serve, and what proof the court needs.

The 91-Day Rule

Under MCR 2.102(D), the summons issued with your complaint is valid for 91 days from the date the complaint is filed. If your spouse isn't served within that window, the action is automatically dismissed without prejudice — meaning you can refile, but you'll pay the filing fee again and restart the clock.

If you're having trouble locating your spouse, file a motion to extend the summons before the 91 days expire. The court can issue a second summons extending the deadline up to one year from the original filing date. There is no third summons — Michigan court rules prohibit it.

Who Can Serve the Papers

You cannot serve the divorce papers yourself. Under MCR 2.103, service must be completed by any adult over 18 who is not a party to the case. This can be:

• A professional process server ($20–$75 in most Michigan counties)
• The county sheriff's office
• A friend or family member (as long as they're over 18 and not involved in the case)

Yes, a friend can serve divorce papers in Michigan — there's no requirement that the server be a professional. But whoever serves must complete the Proof of Service section on the back of SCAO Form MC 01 accurately. An improperly completed proof of service can invalidate the entire service.

Methods of Service

Michigan allows several service methods, each with different response deadlines:

Personal service is the most straightforward — the server physically hands the summons and complaint to the defendant. This triggers a 21-day deadline for the defendant to file an Answer.

Certified or registered mail with restricted delivery and return receipt requested is valid only if the defendant personally signs the return receipt. If someone else at the address signs, or the mail is returned unclaimed, service is not complete. Successful mail service triggers a 28-day response deadline.

Acknowledgment of service — the defendant voluntarily signs the acknowledgment section on the back of Form MC 01. This is equivalent to personal service and triggers a 21-day response window. This is the simplest method when both parties are cooperating.

When Your Spouse Is Avoiding Service

If standard service methods fail after documented attempts, you can request alternate service:

1. File a Motion and Verification for Alternate Service (SCAO Form MC 303) detailing your specific efforts to locate and serve the defendant
2. If the judge approves, they'll issue an Order for Alternate Service (SCAO Form MC 304)
3. The order may allow service by publication in a local newspaper, posting at the courthouse, or other methods the judge specifies

Alternate service is a last resort. Judges want to see genuine, documented attempts at personal service and mail service before approving alternatives. "I tried calling and they didn't answer" won't cut it — you need dated, specific attempts showing due diligence.

Filing the Proof of Service

After service is complete, file the Proof of Service with the court clerk immediately. The court cannot proceed with the case until proof of service is on file. Under MCL 552.6a, the complaint itself isn't even available to the public until proof of service has been filed.

The proof of service must include:

• The date and time of service
• The method used
• The name of the person who completed service
• The location where service occurred (for personal service)

Common Service Mistakes That Delay Michigan Divorces

Serving the papers yourself. Even if your spouse accepts them, service by a party to the case is legally invalid. The court will not recognize it.

Waiting too long to arrange service. If your spouse is difficult to locate, you need time to attempt standard service, document failures, and file for alternate service — all within the 91-day window.

Incomplete proof of service. Missing dates, unsigned forms, or vague descriptions of service method can force you to re-serve, burning through your 91-day window.

The Michigan Divorce Filing Process Guide includes a Service Deadline Tracker worksheet that maps every deadline from the moment you file — so you never lose track of the 91-day clock or the response deadlines that follow.
