Is Cousin Marriage Legal in North Dakota After the 2026 Law Changes?

Yes, cousin marriage is legal in North Dakota under specific conditions. State law permits first-cousin unions if both parties are at least 65 years old or if one is infertile, aligning with N.D. Cent. Code § 14-03-02. No criminal penalties exist for violations, but county clerks may deny licenses absent compliance. Recent 2026 legislative reviews by the North Dakota Legislative Council have not proposed amendments, maintaining the status quo.
