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 prohibited by law. According to Arizona Revised Statutes Section 13-3606, a person commits bigamy when they knowingly marry or purport to marry someone while still being legally married to another individual. 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 means that even if a polygamous marriage is legally performed in another jurisdiction, it would not be recognized as valid in Arizona. The prohibition of bigamy and polygamy applies to all residents of Arizona, regardless of any religious or cultural practices that might otherwise permit such arrangements.
