Common Michigan Divorce Filing Mistakes That Get Cases Dismissed

Filing for divorce pro se in Michigan means the court holds you to the same procedural standards as a licensed attorney. The clerk won't flag errors in your paperwork, the judge won't remind you about deadlines, and a single procedural mistake can get your case dismissed — forcing you to refile, pay the filing fee again, and restart the waiting period from zero.

Here are the mistakes that cause the most dismissals and delays in Michigan divorce cases, and how to avoid each one.

Missing the 91-Day Service Deadline

This is the most common reason Michigan divorce cases get automatically dismissed. Under MCR 2.102(D), the summons expires exactly 91 days after the complaint is filed. If you haven't served your spouse within that window, the case is dismissed without prejudice — meaning you can refile, but you lose your filing fee and your waiting period clock resets.

Many pro se filers don't realize the 91-day clock starts on the filing date, not the date the summons is issued. If you anticipate difficulty locating or serving your spouse, file a timely due-diligence request for a second summons before the 91 days expire. The court may issue a second summons for up to one year from the original filing date, but it cannot issue a third.

Filing in the Wrong County

Michigan requires 180 days of state residency and 10 days of county residency before filing. The county requirement is jurisdictional under Stamadianos v Stamadianos (425 Mich 1), subject to the narrow MCL 552.9(2) exception — meaning the parties can't waive the ordinary requirement, and the court must dismiss the case if the 10-day threshold wasn't met at the time of filing.

If you recently moved counties, count carefully. The 10 days must be consecutive and immediately preceding the filing date. Filing even one day early ordinarily means the court lacks jurisdiction over your case, unless the statutory exception applies.

Incomplete or Incorrect Complaint Forms

The initial filing packet requires specific documents depending on whether you have minor children. A complaint for divorce with children requires the standard Complaint, Summons (MC 01), Confidential Case Inventory (MC 21), Record of Divorce (DCH-0838), and additional forms including FOC 23 (Verified Statement), MC 416 (UCCJEA Affidavit), and DHS 1201-D (Application for IV-D Services).

Filing without the correct forms doesn't automatically dismiss your case, but it can cause the clerk to reject the filing or delay processing. Some counties impose specific size and format standards for MiFILE e-filings, so check the local requirements for the file type you submit.

Improper Service of Process

Michigan has strict rules about who can serve divorce papers and how. The person serving papers must be at least 18 years old and cannot be a party to the case — you cannot serve your own spouse.

Common service errors that invalidate service:

• Serving papers yourself instead of using a third party
• Leaving papers with a family member instead of personally handing them to the defendant (unless you have an Order for Alternate Service)
• Failing to complete the Proof of Service on the back of Form MC 01 and file it with the court
• Using certified mail without restricted delivery — service by mail is only valid if the defendant personally signs the return receipt

Invalid service means the 21-day (personal service) or 28-day (mail service) response deadline never started, and any default judgment entered based on invalid service can be overturned.

Skipping the Financial Disclosure Exchange

Within 28 days after the defendant files their Answer, both parties must exchange SCAO Form CC 320 — the Domestic Relations Verified Financial Information Form — along with the four most recent pay stubs and the most recent federal and state tax returns with schedules. This exchange is mandatory under MCR 3.206 unless both parties waive it in writing or file a complete consent judgment with the complaint.

Failing to exchange CC 320 on time can result in sanctions and can delay the case. If you skip this step, correct the omission promptly through the court's procedures rather than assuming the final judgment is unaffected.

Missing the Parenting Class Requirement

If your divorce involves minor children, your county or court may require parents to complete a court-approved parenting education program (the SMILE program may be used) before the final hearing. This requirement varies by county — format, cost, and registration process all differ.

Pro se filers often discover this requirement late in the process, when they're ready to schedule the final hearing and learn they can't until the certificate is filed. If required locally, register early — ideally within the first month of filing.

Incorrect Default Procedures

When the defendant doesn't respond within the deadline, many pro se plaintiffs assume they can simply ask for a hearing. The default process requires specific steps:

1. File SCAO Form MC 07 (Request and Entry of Default)
2. Serve the default motion, notice of hearing, and proposed judgment on the defendant at least 14 days before the hearing
3. File a Non-Military Affidavit addressing the defendant's military status and Servicemembers Civil Relief Act protections

Missing any of these steps — especially the Non-Military Affidavit — can invalidate the default judgment and expose it to being overturned on appeal.

Not Following Up on the Waiting Period

Michigan's standard waiting periods are 60 days without children and ordinarily 180 days with children. A judge may waive up to the remaining 120 days for unusual hardship or compelling necessity, but not below 60 days. These periods are not automatic triggers: after the applicable period expires, you still need to schedule the final hearing, prepare the proposed Judgment of Divorce, and present proofs to the judge.

Some pro se filers assume the divorce is automatic after the waiting period. It isn't. If you don't take affirmative steps to schedule the final hearing, your case can sit dormant indefinitely — and may eventually be dismissed for lack of prosecution.
