Michigan Compiled Laws, Chapter 700. Estates and Protected Individuals Code § 700.5218

Sec. 5218. (1) The court at the place where the ward resides has concurrent jurisdiction over resignation, removal, accounting, or another proceeding relating to the guardianship with the court that appointed the guardian or in which acceptance of a parental appointment was filed.

(2) If the court located where the ward resides is neither the appointing court nor the court in which acceptance of appointment is filed, the court in which a proceeding subsequent to appointment is commenced in all appropriate cases shall notify the other court, in this or another state, and after consultation with that court, shall determine whether to retain jurisdiction or transfer the proceeding to the other court, whichever will serve the ward's welfare. A copy of an order accepting a resignation or removing a guardian shall be sent to the appointing court or the court in which acceptance of appointment is filed.
