How do you change a custody order in New York?

This page explains New York law on modifying an existing custody or parenting-time order, whether it came from a divorce judgment in Supreme Court or a Family Court order under Article 6 of the Family Court Act, with the court applying Domestic Relations Law 240(1). KOR Law LLP's family law practice handles custody proceedings involving best-interest analyses, modification petitions, and contested visitation matters.

Which court hears a request to change custody?

Usually Family Court. When a divorce judgment sets custody, Family Court may decide an application to modify it on a showing of "a subsequent change of circumstances" and that "modification is required," unless the Supreme Court judgment says it may be modified only in Supreme Court (FCT 652(b)). Supreme Court can also refer custody applications to Family Court (FCT 652(a)). Family Court decides custody petitions with the same powers as Supreme Court and under the same DRL 240(1) standards (FCT 651(a), (b)).

Supreme Court keeps the power, on application by either parent and with notice, to modify the custody directions in its own judgment (DRL 240(1)). If a divorce is still pending, custody is decided within that case; the sequence is covered in how a divorce moves through the New York courts.

What is the legal test?

Appellate Division decisions describe two steps. The parent seeking a change "must show that there has been a change in circumstances since the prior order and, then, if such a change occurred, that the best interests of the child would be served by a modification" (Matter of Michael M. v Makiko M., 2025 NY Slip Op 02832 (3d Dept 2025), quoting earlier Third Department authority). The same threshold applies when the existing order was entered on consent: the petitioner must show a change since the stipulation (Matter of Jones v Brown, 227 AD3d 1523 (4th Dept 2024)).

Once the threshold is met, courts weigh several factors. In Michael M., the court listed the quality of each home environment, the child's need for stability, each parent's willingness to foster the child's relationship with the other parent, past performance, relative fitness, and ability to provide for the child's intellectual and emotional development.

How does the process work, step by step?

1. Read the current order. Check which court issued it and whether Supreme Court kept exclusive power to modify it (FCT 652(b)).
2. Identify what has changed since the order. The threshold looks only at changes after the last order or stipulation (Jones, 227 AD3d 1523).
3. File a modification petition. Family Court custody proceedings are brought by petition and order to show cause or by habeas corpus (FCT 651(b)).
4. Appear and address counsel. A parent seeking custody or contesting a substantial infringement of custody rights has the right to counsel, assigned if the parent cannot afford it (FCT 262(a)(v)).
5. Expect a records review. Before any permanent or initial temporary custody order, the court must review related Article 10 decisions and registry reports, including the orders of protection and sex offender registries (DRL 240(1)(a-1); FCT 651(e)).
6. Evaluation and the child's voice. The court may appoint a licensed forensic evaluator (DRL 240(1)(a-3)) and often hears from an attorney for the child; in Michael M., the court also held an in camera Lincoln hearing with the child.
7. Hearing and decision. The court decides whether the threshold is met and, if so, what arrangement serves the child's best interests.

Can the court change custody while the case is pending?

Yes. The court can issue temporary orders, and the same safeguards apply. Before an initial temporary order, the court must review related Article 10 decisions and registry reports; before a later temporary order, it must do so again unless a review was done within the prior 90 days (DRL 240(1)(a-1)(1), (2)). After the review, the court notifies counsel and any self-represented party of the results before issuing the order (240(1)(a-1)(4)).

Domestic violence allegations have their own rule. Where a parent alleges in a sworn pleading that the other parent committed domestic violence against that parent or a household member, and the allegation is proven by a preponderance of the evidence, the court must consider its effect on the child's best interests and state on the record how those findings factored into the decision (DRL 240(1)(a)).

What changes the answer?

• Deteriorated co-parenting. A breakdown so severe that there is no meaningful communication or cooperation can be a change in circumstances (Michael M., 3d Dept 2025).
• Housing and stability. In Jones, a parent's change in housing and temporary homelessness were part of the change and the best-interests analysis.
• The child's age. An older child's wishes are entitled to great weight where age and maturity make them meaningful (Jones).
• Military service. During deployment, custody may be modified only on clear and convincing evidence that it serves the child's best interests, and return from deployment is a substantial change in circumstances (DRL 240(1)(a-2)).
• Protective actions. A parent who acts lawfully and in good faith on a reasonable belief that the child is being abused may not lose custody based solely on that belief (DRL 240(1)(a)).
• A pending CPS case. Family Court may hear the custody petition jointly with an Article 10 disposition (FCT 651(c-1)); see what happens after Child Protective Services opens an investigation in New York.

Common mistakes

• Relitigating old facts. The threshold looks at changes since the last order (Jones).
• Filing in the wrong court. Check whether Supreme Court reserved modification power (FCT 652(b)).
• Changing the schedule without an order. An informal arrangement does not change the written order, which remains the one the court will look to.
• Discouraging the child's relationship with the other parent. Willingness to foster that relationship is a factor (Michael M.).
• Missing court dates. Orders can be entered in your absence; the general rules for undoing a default are in how to vacate a default judgment in New York.
• Forgetting support. A custody change usually affects support; see how child support is calculated in New York.

Frequently asked questions

Does my child get to choose?

No, but an older child's wishes can carry great weight, depending on age and maturity (Jones v Brown, 4th Dept 2024).

Can I change a custody order I agreed to?

Yes, on the same showing: a change in circumstances since the stipulation, and then best interests (Jones).

Will an indicated CPS report come up?

It can. A register report is admissible in a custody case only if the investigation found some credible evidence (DRL 240(1-a)); challenging the report itself is covered in whether you can clear an indicated CPS report in New York.

Does a custody change affect spousal maintenance?

Maintenance is calculated separately under its own formula; see how spousal maintenance is calculated in a New York divorce.

How is support collected after an order changes?

Support orders are enforced under their own rules, including income executions for support under CPLR 5241 (DRL 240(1)). Those rules differ from creditor garnishment, covered in how much of your wages a creditor can take in New York.

Do I need a lawyer?

Not legally, but a parent seeking custody has the right to counsel, and to assigned counsel if unable to afford one (FCT 262(a)(v)).
