When Child Support Ends in New York

Child support in New York ends when your child turns 21, with some exceptions if they are still in high school

In New York, the parent paying child support (called the obligor) must continue payments until the child reaches age 21. This is the default end date set by state law. However, if your child is still enrolled in high school when they turn 21, support continues until they graduate or turn 22, whichever comes first.

The obligation also ends earlier if the child marries, joins the military, or becomes self-supporting before age 21. If a child dies, support ends when ready. These are the only circumstances that stop support before the child's 21st birthday or high school graduation.

Key Takeaways

• Child support ends on the child's 21st birthday in New York unless they are still in high school.
• If the child is enrolled in high school at age 21, support continues until graduation or age 22, whichever happens first.
• Support stops early if the child marries, enlists in the military, or becomes financially self-supporting.
• The paying parent must notify the court or the child support enforcement office when circumstances change that would end the obligation.

What happens if your child is still in high school at 21

New York law recognizes that some students graduate high school after turning 21. If your child is enrolled in high school on their 21st birthday, child support does not automatically stop. Instead, the obligation continues through the end of that school year or until the child turns 22, whichever comes first.

The paying parent is responsible for knowing whether the child is still in school. If you believe support should have ended because the child is no longer in high school, you can file a motion to modify or terminate support with the court. You will need to provide proof that the child is not enrolled — such as a letter from the school or a withdrawal notice.

Early termination: marriage, military service, and self-support

Child support ends before age 21 in three situations. First, if the child marries, the obligation stops when ready. Second, if the child enlists in the military, support ends on the date of enlistment. Third, if the child becomes self-supporting — meaning they earn enough income to live independently — the paying parent can file to terminate support.

"Self-supporting" does not have a fixed definition in New York law. Courts look at whether the child has stable income, pays their own living expenses, and is no longer dependent on either parent. Part-time work or a small income is usually not enough to end support. The paying parent must file a motion with the court and provide evidence of the child's income and living situation.

How to end support when the child turns 21

Child support does not stop automatically when your child reaches the end date. The paying parent or the child support enforcement office must take action. If support is being collected through the New York State Child Support Enforcement office, that office will close the case when it receives proof that the child has reached the termination date.

If you are paying support directly to the other parent or through the court, you should send written notice to the court and the receiving parent stating that support should end. Include the child's date of birth and the reason support is ending (age 21, high school graduation, or another circumstance). Keep a copy for your records.

If the other parent continues to demand payment after the child reaches the end date, do not ignore it. File a motion to terminate support with the court. Continuing to pay after the obligation ends does not create a new obligation, but it can create confusion and disputes later.

What if your child is in college

New York does not require parents to pay for college or to continue support while a child attends a four-year university or community college. Support ends at 21 (or upon high school graduation if that is later) regardless of whether the child is enrolled in higher education.

However, a court can order college support as part of a divorce or custody agreement if both parents agree or if the court finds it appropriate. This is separate from the automatic child support obligation. If your divorce judgment or custody order includes a college support clause, that obligation may continue beyond age 21 and may have its own end date or conditions.

Modifying support before the end date

If circumstances change before your child reaches the termination date — such as a significant change in income, job loss, or a change in custody — either parent can file a motion to modify support. This does not automatically end support, but it can lower or raise the amount owed.

A modification is separate from termination. You must file a separate motion to terminate support when the child reaches the end date or when one of the early termination conditions is met. Do not assume that the court will automatically close the case.

Frequently Asked Questions

Does child support end automatically when my child turns 21?

No. You must notify the court or the child support enforcement office that the child has reached the end date. If support is being collected through the state, send proof of the child's birth date. If you are paying directly, send written notice to the court and the other parent. Support does not stop until the court or enforcement office receives and processes this notice.

What if my child is 21 but still in high school — when does support end?

Support continues until the child graduates high school or turns 22, whichever is earlier. Once the child graduates or reaches age 22, support ends. You should notify the court or enforcement office of the graduation date so the case can be closed.

Can I stop paying child support if my child moves in with me?

If the child moves in with you and you become the primary custodian, you can file a motion to modify or terminate support based on the change in custody. The court will review the new living arrangement and may reduce or end support. You must file the motion — support does not stop automatically when custody changes.

What if the other parent refuses to acknowledge that support should have ended?

If the other parent continues to demand payment after the child reaches the end date, file a motion to terminate support with the court. Bring proof of the child's age, graduation date, or the circumstance that ended the obligation. The court will issue an order terminating support, and you can use that order to stop payments.

Does support end if my child drops out of high school?

If your child drops out of high school before age 21, support continues until age 21. Dropping out does not shorten the obligation. However, if the child becomes self-supporting after dropping out, you can file a motion to terminate support based on self-support, though you will need to prove the child is truly independent.
