Overview

The Defense of Marriage Act (DOMA) was a United States statute enacted in 1996 and signed by Bill Clinton. It established a federal definition of marriage and set rules about whether states must recognize marriages performed elsewhere. DOMA shaped how the federal government and many state governments treated same-sex couples for nearly two decades and sparked extensive litigation and political debate.

Key provisions

DOMA had two principal components. Section 3 defined marriage for all federal purposes as the union of one man and one woman, thus denying federal recognition and benefits to legally married same-sex couples. Section 2 said that no state was required to recognize a marriage performed under another jurisdiction if that marriage was between same-sex partners, leaving recognition to the states.

Practical effects

Because of Section 3, married same-sex couples who were recognized by their states were often denied federal benefits and programs — including tax filing status, Social Security survivor and spousal benefits, immigration sponsorship, veterans’ benefits, and federal employment benefits. The law therefore created a split between state-level marriage status and federal entitlements.

DOMA was the subject of multiple court challenges. In 2011 the Obama administration informed courts it would not defend Section 3 as constitutional, and several federal courts found Section 3 unconstitutional. Those rulings culminated in the United States v. Windsor decision, in which the Supreme Court on June 26, 2013, struck down Section 3 of DOMA, holding that the federal government could not refuse recognition to same-sex marriages validly performed under state law.

Aftermath and broader significance

The Windsor ruling restored federal recognition for many married same-sex couples and opened the way for uniform treatment of federal benefits. DOMA’s Section 2 remained on the books until the Supreme Court’s 2015 decision in Obergefell v. Hodges, which required states to license and recognize same-sex marriages nationwide. Together these rulings transformed the legal landscape for marriage equality and had lasting social, administrative, and political effects across the United States.

Notable distinctions and ongoing issues

  • DOMA was a federal statute; its two sections addressed different levels of recognition and had distinct legal fates.
  • Even after Section 3 was invalidated, practical disputes continued over benefit administration, retroactive recognition, and related regulatory changes.
  • Debates that surrounded DOMA touched on federalism, equal protection, and the balance between legislative action and judicial review.
