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.
California handles custody in superior courts across all 58 counties, with the Department of Child Support Services running enforcement through local child support agencies (LCSAs). Los Angeles, San Diego, San Jose, San Francisco, Fresno, and Sacramento are the major metros. LAFLA, Bay Area Legal Aid, the California Partnership to End Domestic Violence, and Planned Parenthood affiliates serve women statewide.
