Does Child Support Automatically Stop at 21 in New York? How to Terminate It (and the "Age 23" Question)

The Rule: 21, Not 18, and Not 23

New York is one of a handful of states where the duty of support runs past 18. Both the Family Court Act (§413) and the Domestic Relations Law (§240(1-b)) set the age at 21. That is why a parent who moved here from a state with an 18 cutoff is surprised, and why a parent who read about “support to 23” somewhere is confused. No New York statute carries child support to 22 or 23. The number 23 shows up in agreements, not in the law: parents sometimes promise, in a stipulation, to pay college costs or continue support until a degree is finished or the child turns 22 or 23. A court will enforce that promise as a contract, but it will not impose it on a parent who never made it.

The one true statutory extension is narrow and recent. Since October 2021 a court may order support for an adult child with a developmental disability until age 26 (Family Court Act §413-b; Domestic Relations Law §240-d). It requires a petition and proof of the disability. It is not automatic either.

When Support Ends on Its Own

Look at the order. Most New York orders say something like “until the child reaches the age of 21 or is sooner emancipated.” If there is one child, the order names a termination date or the child’s date of birth, and payments are made directly between parents, the obligation simply ends on the 21st birthday. You do not need permission to stop paying a debt that no longer exists.

Two cautions. First, arrears do not end. Anything unpaid before the birthday is still owed, and it can be collected for years. Second, keep the proof: a copy of the order, the birth certificate, and your payment history. Parents who stop paying without paperwork sometimes spend a year proving they were allowed to.

When You Must File to Stop It

Three situations catch people every year in Erie and Niagara County Family Court.

An unallocated order for more than one child. If the order says “$250 per week for the children” rather than a separate figure for each child, the full amount stays payable when the oldest turns 21. The law does not divide it for you, because the guideline percentage for two children (25%) is not simply double the percentage for one (17%). The remaining amount has to be recalculated, and only a court or a written, court-approved agreement can do that. Until then, the old number is the legal number, and the difference accrues as arrears.

Collection through the Support Collection Unit or an income execution. When your employer deducts support from your pay, the deduction continues until the SCU tells the employer to stop. The SCU works from the order. If the order has a clear end date and one child, the SCU generally closes the case around the birthday, but confirm it in writing before the date and check the first pay stub afterward. If the order is unallocated, or if arrears exist, withholding continues. Overpayments are slow and difficult to recover, so it is far cheaper to file a month or two early than to fix it later.

Emancipation before 21. New York courts recognize a child as emancipated before 21 in a few situations: the child marries, enters the military, becomes fully self-supporting, or, being of working age, leaves home and refuses reasonable parental control. Emancipation is never presumed. The parent who wants to stop paying has to file a petition and prove it, and until the court rules, the order stands. A 19-year-old with a part-time job and a bedroom at home is not emancipated. A 20-year-old with a full-time job, an apartment, and no financial help from either parent may well be.

How to File a Petition to Terminate or Modify

If the support order came from Family Court, you file a Petition for Modification in the county that issued it (Family Court Act §451). If it is part of a Supreme Court divorce judgment, you can usually file in Family Court anyway, unless the judgment kept the matter in Supreme Court. The petition asks the court to terminate support for the child who has aged out or become emancipated and, where other children remain, to set a new amount under the Child Support Standards Act.

Timing matters more than anything else here. A modification is retroactive only to the date you filed, not to the birthday and not to the day the child moved out (Family Court Act §451(1)). Arrears that accrued before the filing date cannot be reduced or cancelled by any court. File before the 21st birthday, not after it.

The faster route, when both parents agree, is a written stipulation that states the new figure, recites what the guideline amount would be, and is submitted to the court for approval. A handshake will not do. The custodial parent cannot privately waive support that belongs to the child, the SCU will keep collecting under the old order, and an informal deal leaves the paying parent exposed to a later arrears claim.

Can the Other Parent Just Cancel It?

The custodial parent can ask the court to terminate an order, and if no public assistance is involved the court will usually grant a consensual termination. What that parent cannot do is cancel it by text message. Support is the child’s right, not the parent’s, and the order stays in force until a court changes it. If the family is receiving public assistance, the Department of Social Services is a party and has its own say.

The College Question

Support does not stop because a child leaves for college, and it does not continue past 21 because a child is still enrolled. What changes is often the add-ons: parents can be ordered to contribute to college costs, often capped at SUNY tuition rates, and many agreements set out who pays tuition, room and board, and for how long. If your stipulation promised support or college contributions past 21, that promise is enforceable. If it did not, the obligation ends at 21 no matter what semester it is.

A Western New York Note

Erie County Family Court at 1 Niagara Plaza and Niagara County Family Court in Lockport both hear these petitions before a support magistrate. Bring the order, proof of the child’s age or emancipation, your current income information, and, if there are other children, the numbers you will need for a new calculation. Our child support calculator will give you the guideline figure for the remaining children before you walk in.

Frequently Asked Questions

Does child support automatically stop at 21 in New York?

Only when the order allows it to. A single-child order with a stated end date, paid directly between parents, ends on the 21st birthday. An order covering several children, or one collected by payroll deduction through the Support Collection Unit, continues until a court modifies it or the SCU closes the case. File before the birthday if anything about your order is unclear.

How do I terminate child support in New York when my child turns 21?

File a Petition for Modification in the Family Court that issued the order, or submit a written stipulation signed by both parents for court approval. Ask the court to terminate support for the child who has turned 21 and, if other children remain, to recalculate the amount under the CSSA. Modifications are retroactive only to the filing date, so file early.

Does New York child support go to age 23?

No. New York law ends the obligation at 21 (FCA §413, DRL §240). Support past 21 exists only where parents agreed to it in a stipulation or separation agreement, for example college costs through age 22 or 23, and then it is enforced as a contract. The single statutory exception is support for an adult child with a developmental disability, which a court may order to age 26 under FCA §413-b.

Can the mother or the custodial parent cancel child support in NY?

Not on her own. Child support belongs to the child, and an order stays in force until a court changes it. The custodial parent can ask the court to terminate the order and, where no public assistance is involved, that request is usually granted. A private agreement to stop paying does not stop arrears from accruing under the existing order.

Do I still pay child support if my child is in college in New York?

Yes, until the child turns 21. College enrollment does not end support and does not extend it. What may change is the add-on for college expenses, which a court can order (often capped at SUNY tuition rates) or which your agreement may already spell out.

My child is 18, out of school and working. Can I stop paying?

Not without a court order. Working is not the same as emancipation. A child of working age is emancipated before 21 only if fully self-supporting and independent of parental control, or in a few other recognized situations such as marriage or military service. You must file a petition and prove it; until then the order stands.
