United States Attorney General Eric Holder plans to announce the changes at a dinner this weekend sponsored by the Human Rights Campaign, a gay rights group.
Holder plans to say that the Justice Department will strive to ensure that same-sex marriages get the same rights, protections, and privileges as heterosexual unions in every federal courthouse.
This includes such matters as bankruptcy proceedings and visitation rights at federal prisons.
United States Attorney General Eric Holder plans to formally introduce the policy Monday.
Human Rights Campaign president Chad Griffin calls this a landmark announcement that will change the lives of committed gay and lesbian couples for the better.
