Michigan's child support program is county-administered: the state Office of Child Support sets policy and runs the statewide disbursement unit, but casework is handled by each county's Friend of the Court (FOC) office, similar in structure to Ohio's CSEAs.
OCS and the local FOC together locate noncustodial parents, establish paternity, set support orders, and collect and enforce payments once a case is active.

How to Apply for Child Support in Michigan
A parent or caretaker of a child applies for Michigan child support services through their county's Friend of the Court office. Families already receiving FIP (Michigan's TANF program) or Medicaid are typically referred for services automatically.
The application requires identifying information for both parents and the child, along with any existing custody or support paperwork. The local FOC then works to establish paternity if needed and get a support order in place.
How to Collect Child Support Payments in Michigan
Michigan collects most support through income withholding once an order is active, processed by the Michigan State Disbursement Unit (MiSDU) and disbursed to the receiving parent.
Payments can be made and tracked through the MiChildSupport portal, and MiSDU has its own 24-hour customer service line, 1-877-543-2660, for payment-specific questions.
Missed Payments & Enforcement
Michigan can intercept tax refunds, suspend licenses, and report arrears to credit bureaus when a parent falls behind on payments, coordinated between OCS and the local FOC.
As in every state, federal law allows a passport to be denied or revoked once past-due support exceeds $2,500.
