Mich. Comp. Laws § 333.1059: Petition for review of order.

Sec. 9.

If a person interested in the welfare of the declarant has reason to believe that an order has been executed contrary to the wishes of the declarant or, if the declarant is a ward including a ward who is a minor child, contrary to the wishes or best interests of the ward, the person may petition the probate court to have the order and the conditions of its execution reviewed. If the probate court finds that an order has been executed contrary to the wishes of the declarant or, if the declarant is a ward including a ward who is a minor child, contrary to the wishes or best interests of the ward, the probate court shall issue an injunction voiding the effectiveness of the order and prohibiting compliance with the order.
