Defense of Marriage Act

The Defense of Marriage Act (DOMA) (Pub.L. 104–199, 110 Stat. 2419, enacted September 21, 1996, 1 U.S.C. § 7 and 28 U.S.C. § 1738C) is a United States federal law that, prior to being ruled unconstitutional, defined marriage for federal purposes as the union of one man and one woman, and allowed states to refuse to recognize same-sex marriages granted under the laws of other states. Until Section 3 of the Act was struck down in 2013 (United States v. Windsor), DOMA, in conjunction with other statutes, had barred same-sex married couples from being recognized as "spouses" for purposes of federal laws, effectively barring them from receiving federal marriage benefits. DOMA's passage did not prevent individual states from recognizing same-sex marriage, but it imposed constraints on the benefits received by all legally married same-sex couples.
