No, it is illegal to marry your first cousin in Nevada. Nevada classifies such marriages as incest under state law, carrying severe criminal penalties. This prohibition stems from concerns over genetic risks associated with close-kin unions.
Nevada’s Legal Framework
Nevada Revised Statute (NRS) 201.180 explicitly bans marriage, sexual relations, or adultery between relatives closer than second cousins, including first cousins and cousins once removed.
These acts are categorized as felonies, with potential sentences ranging from 2 years to life in prison and fines up to $10,000. Even if a cousin marriage occurs legally elsewhere, Nevada deems it void and unrecognized within the state.
The law aims to prevent inbreeding and associated health issues in offspring, reflecting broader public policy against incestuous relationships. Half-cousins may marry, but first cousins cannot, highlighting the strict “closer than second cousins” threshold. Enforcement treats marriage itself as a criminal act, not requiring sexual involvement.
Penalties and Enforcement
Conviction under NRS 201.180 qualifies as a Category A felony due to its gravity. Prosecutors must prove the relationship proximity and the act (marriage or fornication), with no consent defense available. Courts void prohibited marriages automatically, nullifying spousal rights or benefits.
Recent interpretations confirm no changes as of 2026; the statute remains unaltered despite national variations where about half of U.S. states allow first-cousin marriage under conditions like genetic counseling. Immigration contexts may recognize out-of-state cousin marriages if valid locally, but Nevada residency overrides this.
Historical and Cultural Context
Nevada’s ban aligns with eight other states (e.g., Arizona, Texas) criminalizing first-cousin unions, contrasting permissive states like California. Globally, cousin marriage is common in parts of Europe and Asia, but U.S. laws prioritize genetic and familial integrity. Public stigma amplifies legal deterrents, though half-cousin exceptions nod to looser blood ties.
For youth education or community programs, note that violations risk felony records, impacting careers in fields like construction or tech. Legal advice is essential for border cases, such as adoptions or half-blood relations.
