Michigan Compiled Laws, Chapter 600. Revised Judicature Act of 1961 § 600.2045

Sec. 2045. (1) If in an action or proceeding, other than in probate court, it appears that a person not in being may become entitled to a property interest, real or personal, legal or equitable, involved in or affected by the action or proceeding, and the interest of the unborn person is not or cannot otherwise properly be represented and protected, the court, upon its own motion, or upon the motion of any party, may appoint a suitable person to appear and act as guardian ad litem of the unborn person. The guardian ad litem is authorized to engage counsel and do whatever is necessary to defend and protect the interest of the unborn person. A judgment or order made after the appointment shall be conclusive upon the unborn person for whom a guardian was appointed.

(2) The guardian ad litem may be removed by the court which appointed him, without notice, when it appears to the court to be for the best interests of the ward. The guardian ad litem may be allowed reasonable compensation by the court appointing him, to be paid and taxed as a cost of the proceedings as directed by the court.
