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, Kansas does not legally recognize domestic partnerships. This means that in Kansas, there is no state-level legal status that provides same-sex couples with rights similar to those of marriage. In 2005, Kansas passed a constitutional amendment that defined marriage as a union between one man and one woman, effectively banning same-sex marriage until the U.S. Supreme Court's decision in Obergefell v. Hodges in 2015, which legalized same-sex marriage nationwide. Following this decision, same-sex couples in Kansas can marry and receive the same state and federal benefits as opposite-sex married couples. However, for those who choose not to marry, there is no alternative form of legal recognition such as domestic partnership available in the state.
