Bigamy is the act of marrying one person while being legally married to another. Polygamy is the practice or custom (often religious) of having more than one wife or husband at a time. Most states prohibit a party from having more than one marriage license at a time, and in most states bigamy is a crime.
In Arizona, both bigamy and polygamy are illegal under state law. According to Arizona Revised Statutes Section 13-3606, a person commits bigamy when they knowingly contract or purport to contract a marriage with another person while being legally married to someone else. Bigamy in Arizona is classified as a class 5 felony, which can result in serious legal consequences, including imprisonment. The state does not recognize any marriage that is polygamous, and such marriages are considered void. This prohibition applies regardless of whether the practice is based on religious beliefs or customs. Individuals who are found to be practicing bigamy or polygamy may face criminal charges and penalties under Arizona law.
