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.
- 2008 Michigan Child Support Formula Manual – effective 10/1/08
- 2008 Michigan Child Support Formula Manual Supplement – effective 10/1/08
- 2004 Michigan Child Support Formula Manual – effective until 9/30/08
- 2004 Michigan Child Support Formula Schedules – effective until 9/30/08
