No, incestuous relationships, including dating siblings, are criminalized under Nevada Revised Statutes (NRS) 201.180, punishable as a gross misdemeanor or felony depending on age and consent. The Nevada Attorney General’s 2024 enforcement guidelines explicitly target familial sexual conduct, with local district attorneys in Clark and Washoe Counties prioritizing such cases under NRS 201.190’s expanded 2023 amendments prohibiting relationships between parents, children, siblings, and half-siblings.
Key Regulations for Dating Siblings in Nevada
- NRS 201.180 criminalizes “sexual intercourse, cohabitation, or lewdness” between siblings, with penalties escalating to Category D felony (1–4 years imprisonment) if one party is under 18.
- NRS 201.190 (2023 amendment) extends prohibitions to include “dating relationships” deemed exploitative, requiring prosecutors to prove intent to circumvent statutory rape laws.
- Local enforcement directives from the Nevada Board of Examiners for Social Workers (2024) mandate mandatory reporting of suspected incestuous relationships involving minors to the Division of Child and Family Services.
The Nevada Supreme Court’s 2025 ruling in State v. Mendoza affirmed that even consensual sibling relationships may violate public policy, citing “inherent power imbalances.” Exceptions exist only for half-siblings if genetic testing confirms no shared parentage, per NRS 122.020(1)(b). Non-sexual sibling cohabitation remains legal but may trigger child custody disputes under NRS 125C.003.
