Good news is, you need to file a Motion to Enforce the Judgment in Michigan, the state where the Judgment/Orders lie. (They like to keep divorce matters altogether, even the post judgment enforcement issues that are so typical - I've done them 15 years later, can you believe?).
However, there is not a set FORM, generally. Or, more accurately, it is your standard Motion papers (check during the divorce, there was likely a motion or 2 during the divorce, and you simply follow the caption format, change the title to Notice of Motion to Enforce Judgment, etc. Attached to your Motion would be your Certification in Support of Motion, where you'd put all of your facts, including attachments where applicable, such as the decree where it proves what the defendant was supposed to do, etc. Your local court rules will also tell you if you need any other notices attached, proof of service, etc.
Often times, the county court where your matrimonial motion will be made will actually have packets available for pro se parties to make such motions - that would be my first starting point. Could save you time. Secondly, another quick method is to ask around - probably 50% of your friends are divorced and have had Motions done (for or against) and you can simply stem off them. IN fact, your own divorce complaint will give you the entire caption and again, you just need to put in your own title and information pertaining to your request.
Hope this helps to clarify.
