To file for full custody in New York, you submit a written Petition for Custody or Visitation in Family Court in the county where your child lives. There is no filing fee. After you file, the other parent must be formally served, both of you appear before a judge, and if you cannot reach an agreement, the judge decides custody at a hearing based on what best serves the child. The whole process can take a few months or well over a year depending on how contested it becomes.
What Full Custody Means Here
New York splits custody into two parts. Legal custody is the authority to make major decisions about healthcare, education, and religious upbringing. Physical custody, sometimes called residential custody, is where the child actually lives. Sole physical custody means the child lives with one parent more than half the time; the other parent usually gets visitation.1NYCourts.gov. About Custody
“Full custody” isn’t a formal term in the statutes. People use it to mean sole legal and sole physical custody together: one parent makes the major decisions and is the primary home, while the other parent typically has a visitation schedule.
Every custody decision is governed by the “best interests of the child” standard, and neither parent starts with a presumptive right.2New York State Senate. New York Domestic Relations Law 240 – Custody and Child Support Judges weigh the stability of each home, which parent has handled day-to-day caregiving, each parent’s physical and mental health, any history of domestic violence or substance abuse, whether a parent supports or interferes with the child’s relationship with the other parent, and the child’s own wishes if the child is old enough to express a meaningful preference. No single factor decides the case, though documented domestic violence carries substantial weight and can shift the whole analysis.
Where to File and Who Can File
If you are not married to the other parent, or you are married but no divorce is pending, you file in Family Court. That is the most common path, and Family Court has the authority to make initial custody and visitation orders and to modify them later.1NYCourts.gov. About Custody
If a divorce is already underway, custody belongs in that Supreme Court case. The Supreme Court judge can decide custody directly or refer the question to Family Court. Filing a separate Family Court petition while a divorce is active creates jurisdictional problems, so confirm no matrimonial proceeding exists before you file.
Unmarried Fathers Have to Establish Paternity First
If you were not married to the child’s mother, you have no legal right to custody or visitation until paternity is formally established. New York requires either a signed Acknowledgment of Paternity, usually offered at the hospital after birth, or a court Order of Filiation.3NYCourts.gov. Paternity Without one of those, a custody petition from an unmarried father will stall. You can file a paternity petition at the same time as your custody petition, but the paternity question has to be resolved before the court will address custody.
The Home State Rule
Before New York can hear your case, the court has to confirm it has jurisdiction. Under the Uniform Child Custody Jurisdiction and Enforcement Act, priority belongs to the child’s “home state,” meaning the state where the child lived with a parent for at least six consecutive months immediately before the petition was filed. For a child under six months old, home state is where the child has lived since birth.4NYS OCFS. New York Domestic Relations Law Article 5-A – Uniform Child Custody Jurisdiction and Enforcement Act
If the child recently moved to New York and has not been here six months, a New York court likely lacks jurisdiction. Short trips out of state count toward the six-month period; a permanent move restarts the clock.
The Forms You File
The main document is the Petition for Custody or Visitation, Form GF-17, used across every Family Court in the state.5Cornell Law School. New York Comp Codes R and Regs tit 22, General Forms, GF-17 – Petition for Custody or Visitation It asks for the names, dates of birth, and addresses of both parents and the child, and it asks you to explain what custody arrangement you want and why. Write that section as a clear factual summary of why full custody serves the child’s best interests. Vague accusations and emotional language read poorly; specifics carry the day.
Along with the petition, you will need:
- A Summons, which is the official notice telling the other parent about the case and their required first court date.
- A UCCJEA Affidavit (Form UCCJEA-3), a sworn statement listing every address where the child has lived over the past five years and everyone the child lived with at each one. Errors here can raise jurisdictional challenges, so take your time.
Every form is free on the New York State Unified Court System’s website. You do not need a lawyer to complete them.
Keeping Your Address Confidential
If you are a domestic violence survivor and worried the other parent will learn your address through the court file, you have two paths. Anyone in Family Court can ask the judge for an Address Confidentiality Order, which designates an agent (a lawyer, another adult, or the court clerk) to receive papers on your behalf so your real address never appears in the file. New York also runs a statewide Address Confidentiality Program through the Department of State for domestic violence survivors who have relocated; participants get a substitute address, and court papers are routed through the Secretary of State’s office in Albany.6NYCourts.gov. Address Confidentiality in Family Court Cases Either way, your address shows up on documents shared with the other parent as “Confidential.”
Filing and Serving the Other Parent
File the petition, summons, and UCCJEA affidavit at the Family Court clerk’s office in the county where the child lives. There is no filing fee.1NYCourts.gov. About Custody
After filing, the papers have to be formally delivered to the other parent through “service.” You cannot do this yourself. The person delivering the papers must be at least 18 and not a party to the case. A friend, relative, or professional process server all qualify.7NYCourts.gov. How Legal Papers Are Delivered (Service) Professional process servers typically charge $40 to $100 for a standard delivery, more for rush service or multiple attempts.
Papers must be served at least eight days before the first court date. Afterward, whoever delivered them fills out an Affidavit of Service, a sworn statement giving the date, time, location, and method of delivery along with a physical description of the person served. That affidavit has to be filed with the clerk before your first appearance.8NYCourts.gov. How to Serve Papers When Commencing an Action or Proceeding
Your First Court Appearance
The court schedules an initial appearance within a few weeks of filing. Both parents must attend. The judge confirms both parties are present, asks whether each has a lawyer, and outlines what comes next.
Assigned Counsel If You Cannot Afford a Lawyer
New York law guarantees an assigned attorney for any parent seeking custody or opposing another parent’s custody claim, as long as the parent is financially unable to pay.9NYCourts.gov. Family Court Act 262 – Assignment of Counsel for Indigent Persons The judge will advise you of this right at the first appearance. If you think you qualify, raise it right away rather than waiting for a later date.
The Attorney for the Child
In contested cases, the judge typically appoints a separate lawyer called an Attorney for the Child. This attorney represents the child, not either parent. The AFC meets with the child, looks into the situation, and takes a position in court about what the child wants (or, for very young children, what the AFC determines is in the child’s best interests). Judges give the AFC’s position significant weight, so cooperate fully.
Temporary Orders
At or shortly after the first appearance, the judge can issue temporary orders setting a custody and visitation schedule while the case is pending. These are not final. But judges tend to preserve the status quo when they get to the permanent decision, so the temporary arrangement often shapes the outcome. If you believe the current situation is harmful to the child, say so early, with specifics.
Between the First Appearance and the Hearing
Mediation
Many Family Courts encourage or require parents to try mediation before trial. A neutral mediator helps both parents negotiate; they cannot impose a decision or give legal advice. Any agreement has to be written, signed by both parents, and approved by the judge before it becomes an enforceable order. If mediation fails, the case moves toward a hearing. Mediation is generally not appropriate where there is a history of domestic violence, and you can ask to be excused if you would not feel safe negotiating directly with the other parent.
Forensic Custody Evaluations
In highly contested cases, the judge may order a forensic custody evaluation. A court-appointed licensed evaluator conducts individual interviews with each parent and the child, home visits, psychological testing, and a review of school and medical records.10NYS OPDV. Forensic Custody Evaluator (FCE) Certification The evaluator produces a written report with a custody recommendation, submitted to the court and shared with both parties. Judges lean on these reports heavily, though they are not bound by them. Private evaluations can run from $3,500 to well over $10,000; the judge decides how the cost is split, and the court may cover it if both parents are indigent.
The Custody Hearing
If nothing settles the case, it goes to a fact-finding hearing, which is the custody version of a trial. The petitioner goes first. You testify under oath, introduce evidence like text messages, school records, police reports, and medical records, and call witnesses with direct knowledge of the child’s situation. The other parent’s attorney cross-examines you, then the other parent presents their case the same way.
There is no jury. The judge alone weighs the evidence. Complex cases with multiple witnesses and experts often stretch across several sessions over weeks or months.
Lincoln Hearings
When the child is old enough to express a real opinion, the judge may hold a Lincoln hearing, which is a private interview with the child in chambers. The Attorney for the Child is there; the parents and their lawyers are not. The child’s wishes are one factor, not the controlling one, and they carry more weight as the child gets older.
The Decision
After all the evidence is in, the judge issues a written decision applying the best interests factors to your case. The order specifies whether custody is sole or joint, legal and physical, sets a detailed visitation schedule for the noncustodial parent, and imposes any conditions like counseling or supervised visitation. If you are awarded sole custody, the order spells out exactly what rights the other parent retains.
When You Cannot Wait: Emergency Orders
If your child faces an immediate threat of harm, you do not have to wait for the normal timeline. New York courts have temporary emergency jurisdiction when a child is present in the state and has been abandoned, or when emergency intervention is necessary to protect the child or a parent from abuse.11New York State Senate. New York Domestic Relations Law 76-C – Temporary Emergency Jurisdiction
Emergency orders require specific, current facts showing imminent danger. Past misconduct alone or routine parenting disagreements will not do it. You need evidence of what is happening now: ongoing abuse, active substance abuse creating unsafe conditions, or a credible threat that the other parent will flee the state with the child. An emergency order stays in effect until the court with primary jurisdiction can step in or until a longer-term order issues after a full hearing.
Changing a Custody Order Later
If circumstances change after the order is in place, you can file a modification petition. You do not start over. You have to show a meaningful change in circumstances that affects the child’s well-being.12NYCourts.gov. Custody/Visitation Modification Petition – DIY Forms The court then asks whether the current order still serves the child’s best interests or whether something different is warranted.
Courts typically consider changes like a parent developing a substance abuse problem, the child being abused or neglected, a parent’s arrest for a serious crime, a parent relocating to another state, or a parent consistently interfering with visitation. Being unhappy with the original outcome, without new facts, is not enough.
Enforcing an Order the Other Parent Ignores
A custody order is a court order, and violating it has consequences. If the other parent repeatedly refuses to follow the visitation schedule, withholds the child, or ignores other terms, you can file a contempt motion in Family Court. To succeed, you have to show a valid order existed, the other parent knew about it, they had the ability to comply, and they chose not to. Keep a written log of every violation with dates, and save the text messages and emails that document the interference. The court can order makeup visitation time, fines, or in serious cases jail time. The other parent is also entitled to appointed counsel during contempt proceedings if they cannot afford one.9NYCourts.gov. Family Court Act 262 – Assignment of Counsel for Indigent Persons
