Michigan FOC10b Spousal with FOC is a form used in Michigan to calculate the amount of child support that a non-custodial parent should pay to a custodial parent. The form is used by the Friend of the Court (FOC) in Michigan to generate a child support order based on the income and other economic factors of both parents. The form also takes into consideration the number of children in the home, the number of children the non-custodial parent is legally obligated to support, and any other relevant factors. There are two types of Michigan FOC10b Spousal with FOC: the standard version and the simplified version. The standard version is used for most cases, while the simplified version is used for cases involving low-income parents and/or parents with no significant employment income.
