What is considered married by common law?
A common law marriage is a legally recognized marriage between two people who have not purchased a marriage license or had their marriage solemnized by a ceremony. Not all states have statutes addressing common law marriage. In some states case law and public policy determine validity.
What is it called when you have multiple wives?
Polygamy (from Late Greek πολυγαμία, polygamía, "state of marriage to many spouses") is the practice of marrying multiple spouses. When a man is married to more than one wife at the same time, sociologists call this polygyny. If a marriage includes multiple husbands and wives, it can be called a group marriage.
