22 C.F.R. § 92.38
The form of a certificate of authentication depends on the statutory requirements of the jurisdiction where the authenticated document will be used (see § 92.39 regarding the provisions of Federal law). Before authenticating a document for use in a State or Territory of the United States, a consular officer should consult the pertinent law digest to ascertain what specific requirements must be met, or he should be guided by any special information he may receive from the attorney or other person requesting the document with regard to the applicable statutory requirements. (See § 92.41(e) regarding material which should not be in the certificate of authentication.) If no provisions relating to authentications can be found in a particular State or Territorial law digest, and in the absence of any special information from the attorney or other person requesting the document, the officer should prepare the certificate of authentication in the form which seems best suited to the needs of the case. When in his opinion the circumstances seem to warrant, and always in connection with certificates of marriage or divorce decrees, a consular officer should include in the body of his certificate of authentication a qualifying statement reading as follows: "For the contents of the annexed document I assume no responsibility."
