A Michigan Uniform Child Support Order (USO) is a legally binding court order used by the state of Michigan to establish the financial support of a child or children. The order sets out the amount of monthly child support payments that a non-custodial parent is required to pay to the custodial parent for the benefit of the child(men). The order is based on the Michigan Child Support Formula, which uses both parents' incomes and other factors to determine the amount of support. The types of Michigan Uniform Child Support Orders are: initial USO, modification USO, and enforcement USO. An initial USO is issued by the court when a non-custodial parent is found to be responsible for providing financial support for a child or children. A modification USO changes an existing court order to increase or decrease the amount of child support owed by the non-custodial parent. An enforcement USO is issued by the court when a non-custodial parent fails to pay the child support payments outlined in the original USO.
