Child support is administered state-by-state under the federal Title IV-D program, with every state required to operate a Child Support Enforcement (CSE) agency. For custodial mothers, these agencies establish paternity, locate non-custodial parents, calculate orders under state guidelines, and enforce payments through wage garnishment, tax refund intercept, license suspension, and contempt actions. Services are free of charge. Mothers can also pursue retroactive support and modifications when income changes. The federal Office of Child Support Enforcement (OCSE) oversees the program. This directory includes each state's CSE agency, online support calculators, local enforcement offices, and modification resources.
Arizona handles custody (called 'legal decision-making' and 'parenting time') in superior courts across all 15 counties. The Division of Child Support Services operates under DES. Phoenix, Tucson, Mesa, and Chandler are the largest metros. Community Legal Services, Southern Arizona Legal Aid, and the Arizona Coalition to End Sexual and Domestic Violence support women statewide.
