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 the state of Mississippi, both bigamy and polygamy are prohibited by law. Bigamy, which is the act of entering into a marriage with one person while still legally married to another, is considered a criminal offense under Mississippi law. According to Mississippi Code Section 97-29-11, a person who is already married and marries another person or continues to cohabit with a second spouse in the state is guilty of bigamy, which is a felony. The punishment for bigamy can include imprisonment in the state penitentiary. Polygamy, the practice of having more than one spouse at the same time, is not recognized as legal in Mississippi, and the state's marriage laws require that individuals be free from any other marriage bonds before entering into a new marriage. As such, any marriage license issued while another is still in effect would be invalid.
