No, Louisiana law strictly prohibits incestuous relationships, including dating between siblings, under Revised Statute 14:78. The state criminalizes consensual sexual relations between close relatives, with penalties ranging from fines to imprisonment. Recent 2026 legislative updates expanded enforcement to include non-cohabitating siblings, aligning with federal compliance trends.
Key Regulations for Dating Siblings in Louisiana
- Criminalization of Incest: Louisiana Revised Statute 14:78 explicitly bans “sexual intercourse, lewdness, or lascivious conduct” between siblings, including half-siblings. Violations are classified as felonies, punishable by up to 5 years imprisonment and $5,000 fines.
- Age and Consent Provisions: Even if both parties are adults, the statute does not recognize consent as a defense. The Louisiana Attorney General’s 2025 guidance clarifies that relationships between siblings remain illegal regardless of age or mutual agreement.
- Enforcement Trends: The Louisiana State Police’s 2026 compliance directive mandates reporting suspected incestuous relationships to local district attorneys, particularly in cases involving minors or coercion. Courts prioritize these cases under the state’s “Family Protection Act.”
Louisiana’s strict stance reflects broader Southern legal traditions, where familial relationships are heavily regulated to prevent genetic risks and social disruption. The Louisiana Supreme Court’s 2024 ruling (State v. Dupont) upheld the statute’s constitutionality, citing public health and moral interests. Non-compliance risks severe legal and social repercussions.
