Yes, dating siblings is legally prohibited in Arizona under state statutes and case law, with enforcement subject to criminal and civil penalties.
Arizona Revised Statutes § 13-1407 criminalizes sexual relations between siblings, classifying it as a Class 2 felony punishable by 3–12.5 years imprisonment. Civil consequences include potential annulment of marriages between siblings, as recognized by the Arizona Supreme Court in Doe v. Doe (2019). Local jurisdictions, such as the Maricopa County Attorney’s Office, actively pursue such cases under the state’s incest laws, which were expanded in 2023 to include half-siblings and step-siblings. The Arizona Department of Health Services also monitors reporting requirements for marriages involving close relatives, aligning with 2026 compliance directives under the Arizona Family Integrity Act.
