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 Connecticut, bigamy is prohibited under state law. According to Connecticut General Statutes Section 53a-190, a person is guilty of bigamy when, being married, he or she marries another person. Bigamy in Connecticut is classified as a class D felony, which can result in a term of imprisonment and/or a fine if a person is convicted. Polygamy, which involves having more than one spouse simultaneously, is also not legally recognized in Connecticut, and engaging in polygamous marriage would fall under the prohibition against bigamy. The state does not issue more than one valid marriage license to an individual at the same time, and all marriages subsequent to the first legal marriage would be considered invalid under state law.
