Does Michigan have Jurisdiction for your divorce?
At least one of the parties to an action for divorce must have resided in the State of Michigan for at least 180 days immediately prior to the filing of the complaint and must have resided in the county of filing for at least 10 days immediately prior to the filing of the complaint.
If you have minor children living with your spouse in another state for over six months then you should consider filing in that state as that court has jurisdiction over the children. Your spouse can waive that jurisdiction in writing.
You should file the divorce in the county where you presently reside, or in the County where your spouse resides, if she lives in another County. You or your spouse must have a Michigan address in the county where you are filing your divorce. Michigan civilian residents living overseas may file in Michigan if they have maintained their residency in Michigan.
