Marrying your first cousin is legal in Virginia under current state law as of 2026. Unlike 25 states that outright ban first-cousin unions, Virginia permits them without age, fertility, or counseling requirements, provided parties meet general marriage criteria like age 18 (or 16 with consent) and no prior undissolved marriage. This aligns with Virginia Code §20-38.1, which prohibits only ancestor-descendant, sibling, or uncle/aunt-nephew/niece marriages.
Legal Framework
Virginia’s prohibited marriages are narrowly defined: no unions between direct lineals (parents/children/grandparents) or siblings (whole/half blood/adopted), and no uncle/aunt with nephew/niece by blood. First cousins—sharing grandparents but not closer—fall outside these bans, making the marriage valid and recognized statewide. Out-of-state cousin marriages by Virginia residents are also honored, with no voiding clause.
| Prohibited Relationships | Allowed? | Penalty if Violated |
|---|---|---|
| Parent-Child | No | Void ab initio ​ |
| Siblings (full/half) | No | Void ​ |
| Uncle/Aunt-Nephew/Niece | No | Void ​ |
| First Cousins | Yes | None ​ |
| Second Cousins+ | Yes | None ​ |
Cousin marriages aren’t criminalized, distinguishing Virginia from restriction-heavy states like Texas or Kentucky.
Historical Context
Virginia’s law traces to 1975 reforms (c. 644), unchanged through 2020 updates focusing on bigamy and close blood ties. No 2026 legislation alters cousin rules, despite debates on genetics—courts uphold validity absent explicit bans. Common law historically allowed cousin unions, influencing modern statutes.
Practical Steps
Obtain a marriage license from any circuit court clerk ($30 fee); no blood tests or waiting period required. Cousins must affirm no impediments under oath. Ceremonies follow standard protocols—civil or religious. Post-marriage, file the license; records are public.​
Health and Social Considerations
While legal, first-cousin marriages carry a 3-4% higher genetic risk for offspring (double the general 2-3% baseline), per medical consensus—counseling is optional but advised. Prevalence remains low (~0.2% U.S. marriages), culturally accepted in some communities but stigmatized elsewhere. Immigration recognizes Virginia cousin marriages federally.
Common Misconceptions
Social media often lists Virginia among “bans,” confusing it with uncle/niece prohibitions or outdated claims. Half-cousins and once-removed are unequivocally legal. Adoptions don’t trigger bans unless creating sibling-like ties.
Virginia’s permissive stance prioritizes individual choice over genetic concerns. Verify via Virginia Judicial System sites or legal counsel for personal cases—laws evolve minimally here.
