Michigan Compiled Laws, Chapter 700. Estates and Protected Individuals Code § 700.2405

Sec. 2405. (1) If the estate is otherwise sufficient, property specifically devised shall not be used to satisfy rights to homestead allowance or exempt property. Subject to this restriction, the surviving spouse, fiduciaries or others that have the care and custody of minor children, or children who are adults may select property of the estate as homestead allowance and exempt property.

(2) The personal representative may make those selections if the surviving spouse, the adult children, or those acting for the minor children are unable or fail to do so within a reasonable time. The personal representative may execute a deed of distribution or other instrument to establish the ownership of property taken as homestead allowance or exempt property. The personal representative may determine the family allowance in a lump sum not exceeding $18,000.00, adjusted as provided in section 1210,  1 or periodic installments not exceeding 1/12 of that amount per month for 1 year, and may disburse funds of the estate in payment of the family allowance and any part of the homestead allowance payable in cash.

(3) The personal representative or an interested person aggrieved by a selection, determination, payment, proposed payment, or failure to act under this section may petition the court for appropriate relief, which may include a family allowance other than that which the personal representative determined or could have determined.
