Marriage
Marriage - A legal union between individuals that was entered into in a state or other jurisdiction (or foreign country) whose laws authorize the marriage, even if the married couple is domiciled in a state or other jurisdiction (or foreign country) that does not recognize the validity of the marriage. The term also includes common law marriage in a state or other jurisdiction (or foreign country) where such marriages are recognized, so long as they are proven according to the applicable state, other jurisdiction, or foreign laws. The term marriage does not include registered domestic partnerships, civil unions, or other similar formal relationships recognized under state or other jurisdiction (or foreign country) law that are not denominated as a marriage under that state's or other jurisdiction (or foreign country's) law.
