There is a state agency whose entire mandate is collecting the support you’re owed, whose services cost effectively nothing, and which wields tools no private attorney can — and a remarkable number of owed parents have never opened a case. The program operates under Family Code §17400 through local child support agencies (LCSAs) in every county, coordinated by California Child Support Services.
What opening a case gets you: establishment of paternity and support orders if none exist; location services through state and federal parent-locator databases that find employers, addresses, and financial accounts; automatic income withholding with new-hire matching when the payor changes jobs; tax refund intercepts (federal and state), lottery intercepts, and financial institution data matches; license suspension referrals under §17520; passport denial certification for arrears over $2,500; interstate enforcement under UIFSA when the payor leaves California; credit bureau reporting of arrears; and official arrears audits whose accounting courts accept.
What it costs: essentially nothing — a nominal annual fee (currently $35, federally mandated) applies only in never-assistance cases and only after the first $550 collected in a year. No retainers, no contingency percentage.
The honest trade-offs: caseloads are large, so timelines run slower than a motivated private effort; the agency represents the state’s interest in collection, not you personally; and it won’t handle custody or visitation. That’s why the sophisticated play is parallel tracks: LCSA case open for the automated machinery (intercepts, matching, license actions), while you separately record the abstract of judgment, serve levies on known accounts, and seek judicial arrears determinations — private enforcement and agency enforcement are cumulative, not exclusive.
Opening a case takes an application, the support order, and payment history — online enrollment is available statewide. If a case exists but has gone dormant, request a case review and a current arrears audit.
Ten percent interest is accruing either way. The only question is whether the full machinery is running while it does.
