Same-sex marriages in North Carolina became lawful after a federal district court in North Carolina ruled that North Carolina’s ban on same-sex marriage was unconstitutional (Synod v. Cooper, No. 3:14cv213 (W.D.N.C. 2014)). A stay on the decision was lifted after the U.S. Supreme Court declined to review a decision by the 4th Circuit Court of Appeals affirming the unconstitutionality of a state law banning same-sex marriage.
The U.S. Supreme Court subsequently issued a decision legalizing same-sex marriage in all states and requiring all states to recognize same-sex marriages legally performed in other jurisdictions (Obergefell v. Hodges, 135 S.Ct. 2584 (2015)).
Reciprocity. Same-sex and opposite-sex marriages legally performed in other jurisdictions are recognized as legal marriages in North Carolina.
