Mich. Comp. Laws § 552.17: Revision and alteration of judgment concerning care, custody, maintenance, and support of children; enforceability of order.

Sec. 17.

After entry of a judgment concerning annulment, divorce, or separate maintenance and on the petition of either parent, the court may revise and alter a judgment concerning the care, custody, maintenance, and support of some or all of the children, as the circumstances of the parents and the benefit of the children require.

An order concerning the support of a child of the parties is governed by and is enforceable as provided in the support and parenting time enforcement act, 1982 PA 295, MCL 552.601 to 552.650. If this act contains a specific provision regarding the contents or enforcement of a support order that conflicts with a provision in the support and parenting time enforcement act, 1982 PA 295, MCL 552.601 to 552.650, this act controls in regard to that provision.
