How to File for Custody in New York (Family Court Petition Process)

If you're unmarried, separated but not yet divorcing, or otherwise need a custody order without a pending Supreme Court divorce action, Family Court is where you file. The process is designed to be usable without a lawyer, but the sequence of forms and the county-by-county quirks trip up a lot of parents on their first attempt.

Which Court Handles Your Custody Petition

New York splits custody authority between two courts. If you're actively divorcing, custody gets decided inside your Supreme Court matrimonial action — you don't file a separate Family Court case. Family Court has jurisdiction over custody, visitation, and support for unmarried parents, or for married parents who are separated but haven't filed for divorce yet. Family Court Act § 652 is the statutory basis for that jurisdiction, and it's concurrent with Supreme Court's authority, not a substitute for it — once a divorce action starts, any open Family Court custody petition is typically absorbed into the Supreme Court case.

Filing in the wrong court doesn't just cost you time. A petition filed in Family Court while a Supreme Court divorce is already pending can get transferred or dismissed, forcing you to restart the clock on getting a hearing date.

Where to File: Venue Rules

You file your custody petition in the county where the child currently lives. If there's an existing custody order from another New York county, or the child has recently moved, jurisdiction can get more complicated — New York follows the Uniform Child Custody Jurisdiction and Enforcement Act (UCCJEA), which generally ties jurisdiction to the child's "home state" for the six months before filing. If your child has lived in New York for less than six months, or has recently moved from another state, get this checked before you file — filing in the wrong jurisdiction can mean your petition gets dismissed outright.

Step 1: Complete the Custody Petition (Form GF-17)

The New York State Unified Court System provides a free, interactive DIY program that walks you through generating a completed custody petition — this produces the equivalent of Form GF-17, the standard Family Court custody petition. You'll need:

• Your name and address, and the other parent's name and last known address
• The child's full name, date of birth, and current residence
• A brief statement of why you're requesting custody (or a specific custody arrangement)
• Any relevant prior court orders involving the child, in New York or elsewhere
• Whether either parent has any pending or prior Family Offense (domestic violence) proceedings involving the child or family

Family Court filing in custody matters is free — there's no filing fee, unlike Supreme Court divorce actions, which carry an Index Number fee.

Step 2: File With the Clerk's Office

Bring your completed petition to the Family Court clerk's office in the correct county. The clerk reviews it for completeness, assigns a docket number, and schedules your first court date. Many counties are transitioning to mandatory electronic filing (NYSCEF) for certain matters — check with your specific county's Family Court clerk before assuming you can file in person only.

Step 3: Service on the Other Parent

Once filed, the other parent (called the respondent) must be formally served with the petition and a summons notifying them of the court date. You cannot serve the papers yourself — service must be completed by someone over 18 who isn't a party to the case, or in some counties, the court itself handles service by mail or through the sheriff's office. Bring proof of service to your first court appearance if you arranged it yourself.

Step 4: The First Court Appearance

At your first appearance, don't expect a full trial. The judge or a court attorney referee typically reviews the petition, asks both parents about the current situation, and determines next steps. Common outcomes include:

• A temporary order covering custody or parenting time while the case proceeds
• A referral to mediation or the court's alternative dispute resolution program
• A schedule for exchanging financial disclosure or other documentation
• Appointment of an attorney for the child if the case appears contested
• A future court date for a full hearing if the parents can't agree

If both parents show up ready to agree on terms, many cases resolve at this stage or shortly after, with a consent order submitted for the judge's signature.

What Happens If the Case Is Contested

If you and the other parent can't agree, the case moves toward a hearing. The court may appoint an attorney for the child to represent the child's interests, and in more complex cases, order a forensic custody evaluation. Both steps add time and, if privately funded, cost — which is part of why the court pushes parents toward mediation early whenever safety and cooperation allow it.

Common Filing Mistakes

• Filing in the wrong county. Venue follows the child's residence, not either parent's preference.
• Vague relief requests. "I want to see my kids more" isn't specific enough for a court to act on. Be concrete about the schedule or custody arrangement you're asking for.
• Skipping proof of service. Without documented service, the court can't proceed against the respondent, and your case stalls.
• Not disclosing prior orders. Any existing custody, visitation, or Family Offense order involving the same child must be disclosed — omitting one can look like you're trying to conceal something even when it's an honest oversight.

Getting Organized Before You File

The forms themselves are free and available directly through the New York courts. Where parents run into trouble is sequencing everything correctly and knowing what to expect at each stage — especially if you're also trying to negotiate a workable parenting schedule at the same time. The New York Child Custody & Parenting Plan Guide walks through the full filing sequence alongside fillable parenting plan worksheets, so you can walk into your first court date with both your petition and your proposed schedule ready to go.
