No, it is not illegal to marry your first cousin in New York. The state’s Domestic Relations Law explicitly permits first-cousin marriages, making New York one of the more permissive states on this issue.
Legal Framework
New York Domestic Relations Law §5 prohibits marriages only between very close relatives: ancestors/descendants (like parent-child), full or half-siblings, uncles/aunts and nieces/nephews. First cousins—sharing grandparents—are not listed, so licenses issue statewide without issue. This includes half-first cousins, first cousins once removed, and more distant relations like second cousins.
Marriage Process
Couples apply at any town/city clerk’s office, meeting standard requirements: age 18+ (or 17 with consent), ID, and 24-hour wait after application. No genetic counseling or extra steps needed for cousins. Marriages perform via officiant, remaining valid under NY and federal law.
Prohibited Relationships
Interstate Recognition
NY marriages hold in-state, but other states may not recognize them if they ban cousin unions—check residency plans. Federal immigration accepts NY cousin marriages.
Health and Social Notes
No legal mandates address genetic risks, though cousins share about 12.5% DNA, raising some concerns per studies. Cultural views vary, but law prioritizes consent over relation.
