New York Domestic Relations Law (DRL) is the governing statute for everything that happens when a marriage forms, ends, or is renegotiated. Divorce, custody, child support, spousal maintenance, adoption, paternity, and family offense matters all trace back to specific DRL articles. Family matters can be heard in Supreme Court (which has exclusive jurisdiction over divorce itself) or in Family Court (which handles custody, child support, and family offense petitions outside the divorce context). Choosing the right forum is one of the earliest strategic decisions in every case.
Grounds for divorce live in DRL § 170. New York was the last state in the country to adopt no-fault divorce — the no-fault ground (DRL § 170(7), the irretrievable breakdown of the relationship for at least six months) was enacted in 2010 and now drives the overwhelming majority of New York filings. Fault grounds (cruel and inhuman treatment, abandonment for at least one year, imprisonment for three or more years, adultery, and conversion of a separation judgment) remain available but are rarely invoked when no-fault will accomplish the same outcome with less acrimony and lower cost.
Equitable distribution under DRL § 236(B)(5) is the rule that surprises most New Yorkers. New York is NOT a community property state — there is no automatic 50-50 split of marital assets. Instead, the court divides marital property fairly after weighing fourteen statutory factors, including the duration of the marriage, the age and health of the parties, the income and property each brought to the marriage, the loss of inheritance and pension rights from the dissolution, and the tax consequences to each party. Separate property — assets owned before the marriage, inheritances, and gifts to one spouse alone — is generally NOT subject to distribution, although commingling can convert separate property into marital property.
Child support is calculated under the Child Support Standards Act (DRL § 240(1-b)) using a strict percentage formula: 17% of combined parental income for one child, 25% for two, 29% for three, 31% for four, and no less than 35% for five or more children. For 2026, the formula presumption applies to the first $193,000 of combined parental income; above that cap, the court may apply the percentage or deviate based on the same statutory factors. Both caps are adjusted every two years, effective March 1 of each even-numbered year, so confirm the current figure before relying on it. Custody decisions follow the best-interests-of-the-child standard articulated in Eschbach v Eschbach, with separate determinations made for legal custody (decision-making authority over education, medical care, and religion) and residential custody (where the child primarily lives).
