10 U.S.C. § 1044b: Military powers of attorney: requirement for recognition by States

is exempt from any requirement of form, substance, formality, or recording that is provided for powers of attorney under the laws of a State; and shall be given the same legal effect as a power of attorney prepared and executed in accordance with the laws of the State concerned. For purposes of this section, a military power of attorney is any general or special power of attorney that is notarized in accordance with section 1044a of this title or other applicable State or Federal law. Under regulations prescribed by the Secretary concerned, each military power of attorney shall contain a statement that sets forth the provisions of subsection (a). Paragraph (1) shall not be construed to make inapplicable the provisions of subsection (a) to a military power of attorney that does not include a statement described in that paragraph. In this section, the term “State” includes the District of Columbia, the Commonwealth of Puerto Rico, and a possession of the United States.
