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.
Washington superior courts handle family matters in each of its 39 counties. The Division of Child Support operates under DSHS. Seattle, Spokane, Tacoma, Vancouver, and Bellevue are the major metros. Northwest Justice Project, the King County Bar, and the Washington State Coalition Against Domestic Violence (WSCADV) provide statewide civil legal aid and safety services for women.
