In some states, a domestic partnership is a legally recognized relationship between members of a same-sex couple, with rights similar to those of a marriage relationship.
As of my knowledge cutoff in early 2023, Utah does not legally recognize domestic partnerships. In Utah, marriage is defined as a legal union between a man and a woman or a same-sex couple, following the U.S. Supreme Court's decision in Obergefell v. Hodges, which legalized same-sex marriage nationwide. This means that same-sex couples in Utah have the same rights as opposite-sex couples in terms of marriage. However, Utah does not have a separate legal status for domestic partnerships that confers rights similar to those of marriage. Same-sex couples who choose not to marry do not have the same state-recognized legal protections and benefits as those who do marry.
