Support Past 18: The High School Rule and Adult Disabled Children

Eighteen is not always the finish line. California extends support through high school completion, and for adult children unable to support themselves, the duty can continue indefinitely.

What California Law Says

Family Code section 3901 continues support for unmarried children through age 19 or high school graduation, whichever comes first, while section 3910 imposes a duty on both parents to support adult children of any age who are incapacitated from earning a living and lack sufficient means.

How to Collect, Step by Step

1. Calendar the true end date: graduation or 19, not the eighteenth birthday.
2. Keep enforcement running through the statutory period — the earnings assignment does not stop early.
3. For disabled adult children, gather the incapacity record: medical evidence, benefit determinations, functional limitations.
4. File for adult support under section 3910 where the facts qualify; the guideline framework guides the amount.
5. Coordinate with public benefits so support and eligibility work together.

Common Questions

He stopped paying the month our son turned 18, junior year. Correct?

No — full-time high school students collect until graduation or 19; the stopped months are arrears with interest.

Our daughter’s disability means she will never be self-supporting. Does support just end anyway?

Section 3910 exists for exactly this — the parental duty continues, and courts order adult support on the incapacity showing.
