About Child Support for Women
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's official guideline calculator implements the Family Code 4055 formula every judge must apply to set support unless a deviation is justified on the record. Mothers can plug in both parents' incomes, custodial timeshare percentages, deductions, and add-ons to preview likely orders before filing. The output isn't binding, but it gives realistic expectations and helps spot when an opposing party is hiding income. Spanish-language version available.
