New York child custody law is governed by Domestic Relations Law § 240, which places the "best interests of the child" at the center of all custody decisions. Whether you're navigating custody during a divorce proceeding in Supreme Court or filing a standalone petition in Family Court, understanding New York's custody framework is essential for protecting your parental rights.
This comprehensive guide covers New York's custody types, the best interest standard, court jurisdiction, mediation through New York's Presumptive ADR program, and how custody affects child support calculations.

Types of Custody in New York
New York recognizes two types of custody, which can be awarded separately:
Legal Custody
Legal custody refers to the right and responsibility to make major decisions about your child's life, including:
- Education (school choice, special education services)
- Healthcare (medical treatment, therapy, medications)
- Religious upbringing
- Extracurricular activities
- Travel and relocation decisions
Joint legal custody means both parents share decision-making authority. Sole legal custody means one parent has exclusive authority to make these decisions.
Physical Custody (Residential Custody)
Physical custody determines where the child lives and the day-to-day parenting schedule:
- Joint physical custody: The child spends significant time with both parents
- Sole physical custody: The child lives primarily with one parent (the "custodial parent"); the other parent has visitation/parenting time
- Primary residential custody: One parent has the majority of overnights, with the other having scheduled parenting time
Parenting Schedule Calculator
Visualize common custody schedules and calculate parenting time percentages. See how different schedules work for your child's age and your co-parenting situation.
Select Your Situation
50/50 Equal Time Schedules
Child spends one full week with each parent, alternating every week.
Child alternates between 2 days with each parent, then 3 days, ensuring no more than 3 days apart.
Each parent has the same weekdays every week, with alternating 5-day weekends.
Alternating 3 and 4-day blocks provide balance between contact frequency and stability.
Unequal Time Schedules
Child lives primarily with one parent, spending every other weekend with the other parent.
Every other weekend plus one overnight during the week increases non-custodial parent time.
One parent has 4 days, the other has 3 days each week, creating a 60/40 split.
Different ages have different developmental needs
Alternating Weeks (Week-On/Week-Off)
Child spends one full week with each parent, alternating every week.

Which Court Handles Custody in New York?
New York is unique in that custody can be decided in two different courts:
Supreme Court (During Divorce)
If you're getting divorced, custody is determined as part of the divorce proceeding in Supreme Court. The judge will decide custody, visitation, child support, property division, and maintenance all in one case.
Family Court (Standalone Custody)
Family Court handles custody and visitation petitions when:
- Parents were never married
- Parents are separated but not divorcing
- A grandparent or other person seeks custody or visitation
- Modification of an existing custody order is needed
Important: Family Court cannot grant a divorce—only Supreme Court can dissolve a marriage. However, Family Court handles many custody matters and can issue binding custody and support orders.
The Best Interest Standard
Under DRL § 240(1)(a), New York courts must determine custody based solely on the best interests of the child. Unlike some states, New York does not have a statutory presumption for joint custody or equal parenting time.
Courts consider numerous factors, including:
- Stability of caregiving: Which parent has been the primary caretaker?
- Parenting history: Each parent's involvement in the child's daily life
- Ability to cooperate: Each parent's willingness to foster a relationship with the other parent
- Health and safety: Physical and mental health of each parent
- Domestic violence: Any history of abuse or family offense
- Substance abuse: Alcohol or drug issues affecting parenting
- Child's preference: Considered when age-appropriate, though not determinative
- Work schedules: Availability for day-to-day parenting
- Living arrangements: Suitability of each home
- Extended family: Relationships with siblings and other relatives
2025 Legislative Developments
Several bills are pending in the New York Legislature that could change custody law:
- Child Custody Reform Act (S5572/A3822): Would create a uniform statewide custody dispute resolution system with mandatory mediation referrals
- Shared Parenting Presumption (S4128/A4786): Would establish a presumption favoring shared parenting, with the burden on the parent seeking sole custody to prove why shared parenting is detrimental
- Temporary Custody Orders (A6151): Would create a 50/50 rebuttable presumption for temporary custody orders
These bills reflect a national trend toward shared parenting but have not yet been enacted. Current law still applies the pure best interest standard without presumptions.

Presumptive ADR and Mediation
New York's Presumptive ADR initiative refers most civil and matrimonial cases—including custody disputes—to mediation early in the process:
- Early referral: Courts refer cases to mediation at or shortly after the Preliminary Conference
- Voluntary settlement: Participation is encouraged but settlement is not mandatory
- Confidential process: Mediation communications are privileged
- DV exclusions: Cases with credible domestic violence allegations or severe power imbalances may be excluded
Many Judicial Districts have dedicated matrimonial mediation programs with court-approved mediators.
Domestic Violence Considerations
New York takes domestic violence seriously in custody determinations. Under DRL § 240:
- Mandatory consideration: When domestic violence is alleged and proven, courts must consider its effect on the child's best interests
- Orders of protection: Available through Supreme Court (DRL § 252) or Family Court
- Address confidentiality: DRL § 254 allows courts to seal addresses when disclosure poses safety risks
- Address Confidentiality Program: Survivors can use a substitute address for court records
- No forced mediation: DV cases are generally excluded from Presumptive ADR
Child Support Connection
Your custody arrangement directly affects child support calculations. Under the Child Support Standards Act (CSSA) in DRL § 240(1-b):
- Percentage formula: 17% (1 child), 25% (2), 29% (3), 31% (4), 35%+ (5+) of combined parental income
- Income cap: $183,000 combined parental income (as of March 1, 2024)
- Pro rata allocation: Support is allocated based on each parent's share of combined income
- Add-ons: Childcare, health insurance, and educational expenses may be added
