No, it is not illegal to marry your first cousin in New Jersey—state law explicitly permits first-cousin marriages without restrictions like age or fertility stipulations.
New Jersey Marriage Statutes
New Jersey Revised Statutes §37:1-1 outlines prohibited unions, banning marriages between ancestors/descendants, siblings (whole or half-blood), aunts/uncles and nieces/nephews, or grandparents/grandchildren. Notably absent: first cousins, making such unions valid and recognized.
Violations render marriages “absolutely void,” but cousin pairs face no such fate. This aligns New Jersey with 20 other states allowing unrestricted first-cousin marriage, unlike Pennsylvania’s ban across the river.
Reforms since the 1970s decriminalized cousin unions, shifting focus to closer kin while embracing gender-neutral language.
Historical and Cultural Context
Cousin marriage, taboo in parts of the U.S., thrives globally—common in Europe, Asia, Middle East. New Jersey’s permissive stance reflects immigrant influences and avoids genetic overreach, as first-cousin risks mirror unrelated couples at 3-4% birth defects.
No blood tests or counseling required, unlike some cousin-legal states (e.g., Arizona over 65). Same-sex cousins? Equally allowed post-2013 equality rulings.
Application Process
Apply at any municipal clerk’s office (e.g., Newark, Trenton) with ID, SSN, prior divorce proofs if applicable—$28 fee. 72-hour wait; no residency needed for ceremony site. Cousins get standard licenses; clerks process routinely.
Out-of-state cousin marriages by NJ residents? Recognized unless void elsewhere, but local validity holds.
Genetic and Health Considerations
Couples face slightly elevated risks (double recessive traits), but modern screening mitigates. No NJ mandate, though genetic counseling advised voluntarily. Offspring rights unaffected—full inheritance, custody parity.
Legal Implications Post-Marriage
Valid unions grant spousal benefits, taxes, immigration perks. Divorce follows standard no-fault grounds. Bigamy? Still illegal, cousin or not.
Prohibited closer kin face nullity suits, criminal incest charges (§2C:14-2). Cousins? Zero penalties.
Comparisons to Neighboring States
- New York/Connecticut: Legal, like NJ.
- Pennsylvania: Banned.
- Delaware: Legal over 50 or sterile.
Nationally, 18 states fully allow; 8 restrict; 24 ban.
Practical Advice
Discuss family dynamics openly—social stigma persists despite legality. Consult rabbis/imams for cultural rites; NJ officiants (online-ordained ok) perform freely.
Verify via NJ Statutes. New Jersey champions adult choice—marry your cousin lawfully, love without limits.
