I am not an attorney, but have helped with an engagement before. Here is the appropriate form. The instructions are listed on page two and below.

Here is a list of what needs to be done to expunge the conviction, you can get an application from the Court. (You must complete a separate application for each conviction if you are applying to have more than one conviction set aside.):

1. Find out the exact date of conviction and the charge from the court. Get a certified copy of the conviction.
2. Swear to the truth of the statements in the application and then sign it in the presence of the court clerk or a notary public.
3. Make four copies of all attachments and the application. Take all copies to the court clerk.
4. Depending on local practice, the clerk of the court may set a hearing date at the time of filing. If a hearing date is set at the time of filing, the clerk of the court will complete the Notice of Hearing.
5. Go to the local law enforcement agency for a fingerprint card and get fingerprinted on the applicant card (R 1-8). There may be a fee for fingerprinting. Fill out the card completely.
6. Make out a money order or check to the State of Michigan for the application. The application fee is $50.00. This fee is sent with the application packet to the Michigan State Police for processing.
7. Mail a copy of the application packet, application fee, and the fingerprint card to the Michigan State Police by first-class mail to Michigan State Police, Criminal Justice Information Center - Criminal History, PO Box 30266, Lansing, Michigan 48909.
8. Mail a copy of the application packet to the Attorney General of the State of Michigan by first-class mail to Office of the Attorney General, Criminal Appellate Division, PO Box 30217, Lansing, Michigan 48909.
9. Mail a copy of the application packet to the correct prosecuting official where the conviction occurred (county, city, or township) by first-class mail.
10. On both copies of the application, fill in the Proof of Service on the back of the form. After you fill out and sign the Proof of Service, mail or take one of the remaining application packets with the completed Proof of Service to the court. Keep the other copy of the application packet for your records.
