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.
New Hampshire's Circuit Court Family Division handles all family matters statewide. The Division of Child Support Services operates under DHHS. Manchester, Nashua, Concord, and Dover are the largest cities. 603 Legal Aid and the New Hampshire Coalition Against Domestic and Sexual Violence support women, with a strong self-help website for pro se litigants.
