When Child Support Ends in California — And What Happens to Unpaid Arrears

California Child Support Recovery System | Justice Foundation

Understanding when child support ends — and critically, what happens to arrears that have accumulated before termination — is essential for custodial parents planning their enforcement strategy. The end of the support obligation does not mean the end of your right to collect what was owed during the support period.

When California Child Support Terminates

California child support generally terminates when the child reaches age 18 and is not a full-time high school student, or when the child reaches age 19. If the child is still a full-time high school student at age 18, support continues until the child completes 12th grade or reaches 19, whichever comes first. Support also terminates on the child’s emancipation (marriage, active military service, court declaration of emancipation), and on the child’s death. Some support orders include provisions for support of disabled adult children that extend beyond the standard termination date.

Arrears Survive Termination

This is the critical point that many custodial parents don’t fully understand: the termination of the ongoing support obligation does not eliminate arrears that accumulated before termination. If the paying parent owed $50,000 in unpaid support during the years the obligation was active, that $50,000 remains collectible after the child turns 18 — through the same enforcement mechanisms (bank levy, property lien, wage garnishment, tax intercept) that applied during the support period.

California law provides a 10-year statute of limitations on child support judgment enforcement, with the ability to renew the judgment. This means arrears accumulated while your child was a minor may remain collectible well into the child’s adulthood — providing you act to preserve your rights before limitations periods expire.

Maintaining Enforcement After Termination

After the ongoing support obligation terminates, DCSS will continue to enforce arrears collection if you have an open case and have notified them of the remaining balance. Confirm with your caseworker that the case remains open for arrears collection after termination of the ongoing obligation. If you’ve been collecting independently, continue monitoring assets and income for enforcement opportunities. The Justice Foundation kit includes post-termination enforcement procedures and judgment renewal instructions.
