Michigan Child Support Formula

As part of its responsibilities, the State Court Administrative Office's Friend of the Court Bureau (Bureau) developed a formula (guideline) for figuring child support obligation amounts. The law requires courts to use this formula when setting or changing child support obligations.

Child Support Formula Manuals

From time to time, the child support formula is reviewed and changed, and its figures updated for economic changes. When these changes occur, the Bureau issues a new Michigan Child Support Formula Manual. Michigan's guideline consists of the manual and its most current supplement or schedules.
