Child Support Enforcement Mistakes to Avoid

California Child Support Recovery System | Justice Foundation

Even well-intentioned enforcement efforts go wrong when common mistakes are made. Understanding the errors that undermine child support collection — and avoiding them — is as important as knowing which tools to use.

Mistake 1: Accepting Informal Payments Without Documentation

Cash payments, Venmo transfers, and informal arrangements outside the official payment system create accounting nightmares and legal risk. If an obligor pays informally and later disputes the payment history, you bear the burden of proving what was and wasn’t paid. All payments should flow through the State Disbursement Unit where they’re automatically recorded, or if paid directly, must be documented with dated receipts signed by the obligor acknowledging the amount and what period it covers.

Mistake 2: Agreeing to Informal Modifications

An obligor who can’t pay the full amount sometimes proposes informal arrangements: “I’ll pay half now and half next month,” or “Can we just reduce it temporarily?” Accepting these arrangements without a court order creates ambiguity about whether you’ve waived the full amount. Informal arrangements don’t modify the court order — the full amount continues to accrue as arrears. If a genuine temporary reduction is appropriate, file a formal modification motion.

Mistake 3: Letting Arrears Age Without Action

Child support arrears are collectible for 10 years with the ability to renew. But enforcement becomes harder as time passes — the obligor’s assets change, witnesses become unavailable, and documentation gaps accumulate. Arrears that are actively pursued in the year they accumulate are collected at a much higher rate than arrears pursued years later. Don’t wait.

Mistake 4: Failing to Update DCSS on New Information

DCSS can only act on information it has. A new employer, a discovered bank account, an observed purchase suggesting hidden income — each of these is actionable if you report it to DCSS promptly. Information that you hold onto because “DCSS probably already knows” is information that doesn’t generate enforcement action. Report everything relevant promptly and specifically.
