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 Oklahoma, both bigamy and polygamy are illegal. Under Oklahoma law, bigamy is the act of marrying someone while already being lawfully married to another person. This is considered a felony offense. Oklahoma statutes specifically prohibit a person from marrying or cohabitating with another person if they have a living spouse from whom they have not been divorced. The law is clear that a marriage license cannot be issued if either party is already legally married to someone else. Violation of these laws can result in criminal charges, and those found guilty of bigamy may face penalties including fines and imprisonment. It's important to note that these laws apply regardless of whether the subsequent marriage occurred in Oklahoma or another jurisdiction.
