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 the knowledge cutoff in 2023, Arizona does not legally recognize domestic partnerships at the state level. This means that there is no statewide legal status that provides same-sex couples with rights similar to those of marriage. However, some cities within Arizona, such as Phoenix, Tucson, and Tempe, have ordinances that recognize domestic partnerships, primarily to allow couples to visit each other in hospitals and to make health care decisions. These local ordinances do not confer the full range of legal rights that marriage does, such as tax benefits, state employee benefits, or spousal support. Same-sex marriage has been legal in Arizona since October 17, 2014, following a federal district court ruling, and all couples have the right to marry and receive the associated state and federal benefits.
