All states in the US view marriage as a legal union of two people, although the composition of the people may differ in some states.
The term "civil union" is used by several of the United States to describe a legal relationship that is equivalent or substantially equivalent to legal marriage, but which cannot be legally called a "marriage." Civil unions were primarily created for same-sex couples as an alternative to legal marriage, but are not limited to same-sex couples in several states. Several states that permitted civil unions previously have now legalized marriage for same-sex couples.
In states where civil unions are legally recognized, "civil union partner" (or "partner in civil union") is the legal term for what would otherwise be called a "spouse" (i.e. husband or wife) in a legal marriage.
