No, incestuous relationships between siblings are criminalized under Norwegian law, with penalties including fines or imprisonment up to 5 years. The prohibition extends to biological and adoptive siblings, reflecting public policy against familial sexual relations. Local prosecutors, under the Lov om straff (straffeloven) § 206, actively investigate reported cases, though enforcement prioritizes coercion or abuse over consensual acts. Recent 2026 amendments to the Barnevernloven further mandate mandatory reporting by healthcare and social services if minors are involved.

- Criminalization of Incest: Straffeloven § 206 explicitly prohibits sexual relations between siblings, regardless of consent, with penalties escalating if the act involves coercion or minors.
- Adoptive Sibling Prohibition: The law treats adoptive siblings identically to biological siblings, closing loopholes in familial definitions under Familieloven § 1-2.
- Mandatory Reporting Obligations: Under the Barnevernloven § 4-10, professionals (e.g., doctors, teachers) must report suspected incest involving minors to the Barnevernet, triggering investigations by local child welfare authorities.
