When Child Support Ends in New York

Child support in New York ends when the child turns 21, unless the child is still in high school, in which case it continues until graduation or age 19, whichever comes first

The basic rule is straightforward: a parent's obligation to pay child support stops on the child's 21st birthday. However, New York law adds a condition: if the child is still enrolled in high school at age 18, support continues through graduation or until the child turns 19, whichever happens earlier. This means a child who graduates at 17 stops receiving support at that point, but a child who is still in 12th grade at 18 can receive support through the graduation ceremony.

The paying parent does not automatically stop payments on the termination date. Instead, the parent must file a motion to terminate support with the court, or the support order itself may state an automatic end date. If neither happens, payments can continue past the legal end date. The receiving parent can also file a motion to extend support in limited circumstances, such as if the child has a disability or is in college.

Key Takeaways

• Child support ends on the child's 21st birthday unless the child is still in high school, in which case it ends at graduation or age 19, whichever is sooner.
• The paying parent must file a court motion to stop payments; support does not end automatically even after the child reaches the age limit.
• A child who is disabled or in college may be able to receive extended support if the court finds it appropriate, but this requires a separate motion.
• If the child drops out of high school before age 19, support typically ends at that point rather than continuing to age 19.
• The support order itself may include an automatic termination date, which overrides the general rule if it is earlier.

How the 21st birthday rule works in practice

When a child turns 21, New York law presumes the obligation to pay child support ends. This applies to all types of support orders: those set by the court, those agreed to between parents, and those modified over time. The 21st birthday is a hard stop unless a specific exception applies.

The paying parent is responsible for notifying the court or the receiving parent that the child has reached age 21 and requesting termination. Many parents assume the obligation straightforward ends, but the Family Court system does not automatically close cases. If the paying parent continues to pay after age 21, the money is a gift, not a legal obligation. If the paying parent stops paying without filing a motion, the receiving parent can file a violation petition claiming the support order is still in effect.

The high school exception: support until graduation or age 19

If a child is still enrolled in high school when they turn 18, child support continues. The obligation ends on whichever date comes first: the date the child graduates from high school or the child's 19th birthday. This rule exists because New York recognizes that some children graduate later than others.

The child must be enrolled in a public or private high school for this exception to explore. Homeschooling, GED programs, and alternative schools may not may have access to, depending on how the court interprets the order. If there is a dispute about whether the child is truly enrolled, the receiving parent may need to provide school records to the court.

If the child drops out of high school before age 19, support typically ends at the time of withdrawal. The paying parent should document the dropout and file a motion to terminate, or notify the receiving parent in writing with proof of the withdrawal date.

What happens if the child is disabled

New York law allows child support to continue past age 21 if the child is unable to be self-supporting due to a disability that existed before age 21. The receiving parent must file a motion with the court and provide medical evidence of the disability. The court then decides whether to extend support and for how long.

The disability does not have to be severe. The court looks at whether the child can work and support themselves, not whether the disability is permanent. A child with autism, cerebral palsy, intellectual disability, or a serious mental health condition may meet this standard. The court may order support to continue indefinitely, or it may set a review date to reassess the child's ability to work.

College attendance and extended support

New York does not automatically extend child support for college attendance. Once the child turns 21 or graduates high school (whichever is later), support ends even if the child is enrolled in a four-year university. However, the receiving parent can file a motion asking the court to extend support for college expenses.

The court has discretion to order extended support for college if it finds that the parents had the financial means to pay for college and the child is enrolled full-time in an accredited college or university. The court considers the parents' income, the cost of the college, and whether the child is making reasonable progress toward a degree. This is not automatic and requires a separate court proceeding.

How to file a motion to terminate support

The paying parent files a motion to terminate child support in the Family Court in the county where the original support order was issued. The motion must include the child's date of birth, the date the child turned 21 (or graduated high school), and a copy of the current support order. Some courts have a form for this; others accept a letter or a standard motion.

The receiving parent receives a copy of the motion and can object if they believe support should continue—for example, if the child is still in high school or has a disability. The court then schedules a hearing or decides the motion on the papers. If the court agrees that support should end, it issues an order terminating the obligation.

If the receiving parent files a motion to extend support (for disability or college), the same process applies: both parents receive notice, both can present evidence, and the court decides. The burden is on the receiving parent to show why support should continue past the legal end date.

What happens to arrears (back support owed)

If the paying parent owes back child support—money that was due but not paid in previous months or years—that debt does not disappear when the child turns 21. Arrears are a separate obligation from ongoing support. The receiving parent can continue to collect arrears through wage garnishment, tax refund intercept, or a judgment against the paying parent.

Arrears can be collected for years after the child reaches age 21. There is no statute of limitations on child support arrears in New York, meaning the receiving parent can pursue collection at any point in the future. If the paying parent wants to settle or modify arrears, they must file a motion with the court.

Frequently Asked Questions

Does support automatically stop when my child turns 21?

No. The paying parent must file a motion to terminate support with the court. If no motion is filed, the obligation continues even after age 21. The receiving parent can also continue to collect if the paying parent does not take action to end the order.

My child is 18 and still in high school. When does support end?

Support continues until your child graduates from high school or turns 19, whichever happens first. Once either event occurs, the paying parent can file a motion to terminate. If your child is still in 12th grade at age 19, support ends on the 19th birthday regardless of graduation status.

Can support continue if my child goes to college?

Not automatically. The receiving parent must file a motion asking the court to extend support for college. The court may order extended support if both parents had the means to pay for college and the child is enrolled full-time in an accredited school, but this is not may provide.

What if my child has a disability?

The receiving parent can file a motion to extend support if the child became disabled before age 21 and cannot be self-supporting. The court reviews medical evidence and decides whether to extend support. This requires a separate court proceeding and is not automatic.

If I owe back support, does that end when the child turns 21?

No. Arrears (back support owed) continue to be collectible indefinitely in New York. The receiving parent can pursue collection through wage garnishment or tax intercept long after the child reaches age 21. Arrears are separate from the ongoing support obligation.
