New Hampshire legally recognizes marriage between two individuals of the same sex (NH Rev. Stat. Sec. 457:1-a). Civil unions are no longer permitted under the law.
Employers are required to provide benefits on an equal basis to employees in same-sex or opposite-sex marriages.
Same-sex marriages or civil unions entered into outside the state are valid in New Hampshire, unless the relationship violates state law.
The U.S. Supreme Court issued a decision in 2015 legalizing same-sex marriage in all states and requiring all states to recognize same-sex marriages legally performed in other jurisdictions (Obergefell v. Hodges, No. 14-556 (6/26/15)).
