No. Under the Federal Defense of Marriage Act (DOMA), the federal government respects only those marriages between a man and a woman. So even if a same-sex couple's marriage is recognized by their home state, the marriage still won't be recognized under federal law. This means that same-sex married couples cannot take advantage of the 1,138 federal laws that confer rights, benefits, and protections to married heterosexual couples -- such as Social Security spousal survivor and retirement benefits, the ability to file joint tax returns, and qualification for special estate planning benefits.
