How Child Support Ends in Delaware: Emancipation, Termination Orders and What to File
Delaware current child support terminates by operation of law at the age limits or when custody of all children moves to the paying parent, and you usually need not file anything. If it does not end in the records, file a Motion to Revoke Child Support; arrears stay owed until paid.
Does child support end automatically in Delaware?
Yes, in the cases the statute lists. An order of current child support terminates by operation of law when all minor children have reached 18 (or the diploma or 19 for a high school student), or when custody of all the children is transferred to the obligated parent by a court order or the parents’ written voluntary agreement (13 Del. C. 517(a)-(b)). The Family Court says that in those cases you usually do not need to file anything.
What is a Notice of Administrative Adjustment?
Within 120 days before or 30 days after adjusting its accounts, the Division of Child Support Services files a Notice of Administrative Adjustment with the Court explaining the action and sends it to both parties. Changes made by operation of law include terminating support, imposing an arrears payment, changing the payee, the death of a parent or child, and reducing support for incarceration of at least 180 days on orders issued after January 31, 2019 (Family Court FAQ, Chapter 12).
What if you disagree, or support should have ended and nothing happened?
If you disagree with an administrative adjustment, file a Motion to Contest an Administrative Adjustment; the other party has 10 days to respond. If you believe your obligation terminated by operation of law and you received no Notice, file a Notice and Motion to Revoke Child Support. That motion may be filed only where current support has terminated by operation of law for all children on the order or where arrears have been paid in full; any other change needs a petition to modify.
What events does Delaware list as emancipation?
The child support statutes we read (sections 501 and 517) do not list emancipation events such as marriage or military service, so we do not state a list. If the child marries, enlists or becomes independent before 18, ask a licensed Delaware attorney whether to file a petition to modify; a termination before 18 that is not one of the listed events needs a court order.
What does the timeline look like?
| Situation | What happens |
|---|---|
| All minor children reach 18 | Current support terminates by operation of law |
| Child over 18 in high school, likely to graduate | Terminates at the diploma or age 19, whichever is first |
| Custody of all children moves to the obligated parent | Current support terminates (court order or written voluntary agreement) |
| Court orders a change of primary residential placement | Give DCSS a copy of the order for an administrative adjustment |
| Death of a parent or child | The Division can make an administrative adjustment |
| Past-due support | Stays owed until paid in full |
Do arrears stay owed after support ends?
Yes. The obligation to pay arrears terminates by operation of law only when all arrears or past-due support have been paid (517(c)). Check the balance in the Delaware arrears calculator and the date in the Delaware child support end date calculator.
What mistakes cause problems when support ends?
- Stopping payments before the order terminates by operation of law.
- Not giving DCSS a copy of a custody or placement order.
- Forgetting that a wage attachment may continue until the employer is told to stop.
- Forgetting that past-due support is still collectible.
