No, incestuous relationships, including dating siblings, are criminalized under Oregon Revised Statutes § 163.525, classifying them as Class C felonies punishable by up to 5 years imprisonment and $125,000 in fines. The Oregon Department of Justice actively enforces these provisions, with recent 2026 legislative proposals targeting enhanced penalties for familial sexual exploitation. Consent is legally irrelevant in such cases, as state law prioritizes genetic and familial integrity over individual autonomy.
Key Regulations for Dating Siblings in Oregon
- Criminalization of Incest: ORS § 163.525 explicitly prohibits sexual relations between siblings, including half-siblings, with penalties escalating for coercive or underage conduct.
- Age and Consent Exceptions: No legal recognition exists for sibling relationships, even with mutual consent; Oregon’s statutory rape laws (ORS § 163.375) further restrict minors in such dynamics.
- Enforcement Priorities: The Oregon State Police’s Sex Crimes Unit collaborates with county DA offices to investigate reported cases, particularly where power imbalances or coercion are alleged.
Local jurisdictions, such as Multnomah County’s Family Abuse Prevention Program, may intervene in non-criminal but high-risk sibling relationships under civil protective orders, though this does not legalize the relationship. Oregon’s 2026 budget allocates $3.2M to expand incest-related prosecutions, signaling stricter enforcement. Consultation with a Portland-based family law attorney is advised for nuanced interpretations, as case law occasionally challenges statutory rigidity.
