Yes, cousin marriage is legal in Washington, D.C., provided the parties meet specific statutory and public health requirements. The District follows D.C. Code § 46-401, which permits first-cousin unions without additional judicial approval, unlike some states requiring genetic counseling or court petitions. However, applicants must comply with D.C.’s marriage license issuance protocols, including blood tests (mandatory until 2026 per the D.C. Department of Health’s Health Regulation and Licensing Administration directive) and proof of identity. Non-residents face no residency restrictions but must adhere to D.C.’s procedural framework.
