No, incestuous relationships, including dating siblings, are criminalized under Wisconsin Statutes § 944.06, punishable as a Class F felony. State law explicitly prohibits sexual relations between siblings, with enforcement historically prioritized in rural counties like Outagamie and Marathon. Recent 2026 legislative proposals aim to expand reporting requirements for healthcare providers under Wis. Admin. Code § DHS 140, potentially increasing scrutiny of familial relationships.
Key Regulations for Dating Siblings in Wisconsin
- Criminal Prohibition: § 944.06 criminalizes “sexual intercourse or sexual contact” between siblings, with penalties up to 12.5 years imprisonment and $25,000 fines. Consensual relationships are not exempt.
- Reporting Mandates: Under 2026 amendments to Wis. Admin. Code § DHS 140, healthcare professionals must report suspected incestuous relationships if they present evidence of coercion or harm, triggering investigations by the Wisconsin Department of Health Services.
- Employment & Licensing Risks: Professionals (e.g., teachers, social workers) convicted under § 944.06 face mandatory license revocation via the Wisconsin Department of Safety and Professional Services, per 2025 Act 347.
Local enforcement varies; Dane County District Attorney’s Office has historically pursued cases involving minors or evidence of exploitation. Wisconsin’s statutes reflect a strict public policy against familial sexual relationships, diverging from states like New Jersey, which decriminalized sibling incest in 2023. Consultation with a Wisconsin-licensed attorney is advised for nuanced interpretations.
