About Child Support for Fathers
Child support in the United States is administered state-by-state under the Title IV-D federal program, with every state required to operate a child support enforcement agency. These agencies establish paternity, locate non-custodial parents, calculate support obligations, and enforce payments through wage garnishment, tax refund intercepts, license suspension, and other civil enforcement tools. Support amounts are calculated using state-specific guidelines, most based on an income shares or percentage-of-income formula. Fathers paying support can request modifications when their income drops substantially or when circumstances change (job loss, additional children, disability). Fathers owed support can open a case with their state agency free of charge. This directory includes each state's child support agency, online calculators, local enforcement offices, and modification resources.
