I knew poligamy was legal in Utah.I didn't think anyone actually did it...and 5 wives.
Part of the law against bigamy in Utah was struck down by a federal court, but the gist of the prohibition remains in force:
https://ecf.utd.uscourts.gov/cgi-bin/show_public_doc?211cv0652-78 "The court finds the cohabitation prong of the Statute unconstitutional on numerous grounds and strikes it. As a result, and to save the Statute, the court adopts the interpretation of “marry” and “purports to marry,” and the resulting narrowing construction of the Statute, offered by the dissent in State of Utah v. Holm, 2006 UT 31, 131-53, 137 P.3d 726, 758-66, thus allowing the Statute to remain in force as prohibiting bigamy in the literal sense—the fraudulent or otherwise impermissible possession of two purportedly valid marriage licenses for the purpose of entering into more than one purportedly legal marriage."
Basically, you are allowed to legally marry only one wife, but you can live together with as many women as you can convince to do so. Presumably you can do that without marrying anyone as well.
