Is Dating Siblings Legal in Washington D.C. After the 2026 Policy Reforms?

No, incestuous relationships, including dating between siblings, are criminalized under D.C. Code § 22-1901.

Key Regulations for Dating Siblings in Washington D.C.

  • D.C. Code § 22-1901 criminalizes sexual intercourse between siblings, classifying it as a felony punishable by up to a decade in prison. The statute does not distinguish between full or half-siblings, applying uniformly to all lineal descendants.
  • No Exceptions for Consent: Unlike some states, D.C. does not recognize a “close-in-age” or “consenting adults” exception for sibling relationships. The law treats all such unions as inherently unlawful, regardless of mutual agreement.
  • Enforcement Priorities: While prosecutions are uncommon, the D.C. Office of the Attorney General (OAG) retains discretion to pursue charges under public morality statutes, particularly in cases involving minors or coercion. Local law enforcement agencies may investigate reports but prioritize other criminal matters.
