## Abstract

The Department of Labor's (Department) Wage and Hour Division (WHD) revises the regulation defining "spouse" under the Family and Medical Leave Act of 1993 (FMLA or the Act) in light of the United States Supreme Court's decision in United States v. Windsor, which found section 3 of the Defense of Marriage Act (DOMA) to be unconstitutional.
