U.S. Office of Treaty Affairs

The Office of Treaty Affairs serves as the principal U.S. government repository for U.S. treaties and other international agreements.  In addition, the treaty office is also the depositary for over 200 multilateral treaties.  These include treaties like NATO, the Antarctic Treaty, and the Biological Weapons Convention.  The treaty office advises other offices under the Legal Adviser, other Department bureaus, and other government agencies on all aspects of treaty law and procedure, including constitutional questions, and provides guidance and assistance in the authorization, drafting, negotiation, application, and interpretation of hundreds of agreements annually.  It also responds to treaty-related inquiries from Congress, academia, members of the public, and officials of foreign governments and international organizations.
