Mich. Comp. Laws § 600.3324

Sec. 3324. (1) The provisions concerning partition are applicable to lands held by a trustee for the benefit of others, and a claim for partition may be instituted by the trustees or any person interested in the lands held in trust. (2) When the original parties in interest in the trust, or any of them, have died, leaving heirs or legatees or others interested by title or right through them or any of them in the lands held in trust, the court, at its discretion, may divide the land by judgment among the heirs, legatees, or others representing the interests of the deceased in those lands so as to set off the interest of all of these persons together, without subdivision among them.
