New York Family Law Essentials: Divorce, Custody, and Support
New York family law governs the legal dissolution of marriages, the allocation of parental rights and responsibilities, and the financial obligations that flow between former partners and between parents and children. These matters are adjudicated primarily in New York Family Court and the Supreme Court of New York State, operating under a framework established by the Domestic Relations Law (DRL) and the Family Court Act (FCA). The structure and outcomes of these proceedings have direct consequences for housing, income, and child welfare for millions of New York residents.
Definition and scope
New York family law, as codified in the New York Domestic Relations Law and the Family Court Act, covers four principal subject areas: divorce and legal separation, child custody and visitation, child support, and spousal support (maintenance). Each area carries distinct procedural tracks, evidentiary standards, and modification rules.
Divorce in New York may be filed on no-fault grounds — specifically, irretrievable breakdown of the marriage for a period of at least six months (DRL § 170(7)) — or on fault-based grounds including cruel and inhuman treatment, abandonment, imprisonment, or adultery. No-fault divorce, available since 2010 following amendment of the DRL, represents the dominant filing basis in most counties.
Custody encompasses two distinct legal concepts:
- Legal custody — the authority to make major decisions regarding a child's education, healthcare, and religious upbringing.
- Physical custody — where the child primarily resides.
Either form may be awarded solely to one parent or shared jointly. The Family Court Act directs courts to apply a "best interests of the child" standard, an equitable standard rather than a statutory formula, shaped by case law developed through the Appellate Divisions.
Child support is calculated using the Child Support Standards Act (CSSA), codified at DRL § 240 and Family Court Act § 413. The CSSA applies a percentage of combined parental income: 17% for one child, 25% for two children, 29% for three children, 31% for four children, and no less than 35% for five or more children (New York State Unified Court System, Child Support Guidelines).
Maintenance (spousal support) is governed by DRL § 236B, which provides a statutory formula for both temporary and post-divorce maintenance based on income differentials between the parties.
How it works
Family law proceedings in New York follow parallel tracks depending on the relief sought and whether the parties are or were married.
Divorce proceedings are initiated in the Supreme Court of New York (the trial court of general jurisdiction), not in Family Court. A summons with notice or a summons and verified complaint is filed through the New York State Courts Electronic Filing system (NYSCEF). The defendant has 20 days to respond if served in New York State, or 30 days if served outside the state.
The process moves through these discrete phases:
- Commencement — Filing of summons, service of process on the respondent/defendant.
- Automatic orders — Upon commencement, automatic restraining orders (DRL § 236B(2)(b)) take effect, prohibiting either party from dissipating marital assets, changing beneficiaries, or removing children from the state.
- Pendente lite relief — Either party may seek temporary orders for custody, support, or exclusive use of the marital home while the case is pending.
- Discovery and disclosure — Each party must file a Statement of Net Worth disclosing income, assets, and liabilities. Financial disclosure is mandatory in contested proceedings.
- Resolution — Cases resolve through a negotiated stipulation of settlement, a judicial determination at trial, or a combination (e.g., settlement on equitable distribution with contested custody proceeding).
- Judgment of divorce — Entered by the Supreme Court upon satisfaction of all conditions. Ancillary matters (child support enforcement, custody modifications) may transfer to Family Court post-judgment.
For the broader regulatory structure governing New York courts, including jurisdictional boundaries and court hierarchy, the regulatory context for the New York legal system provides a foundational reference.
Equitable distribution applies to marital property under DRL § 236B(5). New York is an equitable distribution state, not a community property state. Courts divide marital property — assets acquired during the marriage — based on 13 statutory factors, including the duration of the marriage, each spouse's income and earning capacity, and any wasteful dissipation of assets.
Common scenarios
Uncontested divorce — Both parties agree on all terms: grounds, property division, maintenance, custody, and support. A settlement agreement is drafted, signed, and submitted to the court along with the divorce forms. No court appearance is typically required. Uncontested divorces can often be processed in 3 to 6 months, depending on county case volume.
Contested custody — Parties cannot agree on legal or physical custody arrangements. The court may appoint an Attorney for the Child (AFC) to represent the child's interests independently, pursuant to 22 NYCRR § 7.2. A forensic evaluator may be appointed to assess parental fitness and the child's needs.
Custody modification — After a custody order is entered, either parent may seek modification by demonstrating a substantial change in circumstances. The threshold requires more than minor life changes; the petitioning party must establish that modification serves the child's best interests.
Child support deviation — The CSSA formula applies up to a combined parental income of $163,000 (the income cap as set by statute, adjusted periodically). Above that threshold, courts have discretion to apply the percentage formula, consider the factors enumerated in FCA § 413(1)(f), or apply both. Parties may deviate from the guideline amount by written agreement, provided the agreement acknowledges the guideline amount and states the reasons for deviation.
Domestic violence in family proceedings — Where a party alleges domestic violence, Family Court has jurisdiction to issue Orders of Protection under Family Court Act Article 8. These proceedings run parallel to, and may intersect with, divorce and custody matters. Detailed coverage of protective orders and safety-planning legal tools appears at New York Domestic Violence Legal Protections.
Paternity and support for unmarried parents — Family Court, not Supreme Court, has primary jurisdiction over support and custody matters between unmarried parents. Paternity may be established by an Acknowledgment of Paternity signed at birth or through a court-ordered genetic test under Family Court Act Article 5.
Decision boundaries
Several structural distinctions determine which court has jurisdiction and which statutory framework applies.
Supreme Court vs. Family Court jurisdiction:
| Matter | Supreme Court | Family Court |
|---|---|---|
| Divorce | ✓ Exclusive | ✗ |
| Custody (married parties, pending divorce) | ✓ | ✓ (by referral) |
| Custody (unmarried parties) | ✗ | ✓ |
| Child support enforcement post-judgment | ✗ | ✓ |
| Orders of Protection | ✓ (incidental) | ✓ (primary) |
Residency requirements — To file for divorce in New York, at least one of the following conditions must be met (DRL § 230): the parties were married in New York and either party is a resident at the time of filing; the parties resided as a married couple in New York and either party is a resident; or either party has been a New York resident for a continuous period of at least two years immediately preceding the commencement of the action.
Interstate custody — UCCJEA: New York has adopted the Uniform Child Custody Jurisdiction and Enforcement Act (UCCJEA) under DRL §§ 75-a through 75-z. Under the UCCJEA, New York courts have jurisdiction to enter an initial custody order only if New York is the child's "home state" — defined as the state where the child has lived for at least 6 consecutive months immediately before the commencement of proceedings.
Separation agreements vs. divorce judgments: A legal separation under DRL § 200 requires a written, notarized separation agreement but does not dissolve the marriage. After living under the agreement for one year, either party may convert the separation into a divorce by filing the agreement with the court under DRL § 170(6). This track is distinct from divorce on no-fault or fault grounds.
Child support vs. maintenance modification standards: Child support orders are subject to modification upon a substantial change in circumstances, a change in either party's gross income by 15% or more since the last order, or upon reaching the three-year review trigger under DRL § 236B — whichever occurs first. Maintenance modification requires a substantial change in circumstances but does not carry an automatic three-year review right.
