Wyoming Secretary of State


Overview: Authentication Services

Apostille Certification

On October 15, 1981, the United States became part of the 1961 Hague Convention abolishing the requirement of Legalization of Foreign Public Documents. The Convention simplified the authentication process of public documents to be used in nations that are members of the 1961 Hague Convention. Only those nations party to the Hague Treaty will recognize the apostille certification.

Certification Certificate

If a document is going to be used in a nation not party to the 1961 Hague Convention, then a certification certificate is used in place of an apostille. These foreign governments also require the U.S. Department of State and the Embassy or Consulate of the foreign nation where the document is to be used to authenticate the document in order for it to be considered legal.

Document Requirements

  • The document must be certified by a Wyoming official such as a County Clerk or Deputy, State Registrar or Deputy, State Examiner, or acknowledged before a Wyoming Notary Public.
  • All signatures must be original.
  • All documents in a foreign language must be accompanied by a certified (notarized) English translation.
  • Fees: The fee is $3 per document. All checks (personal or company) or money orders should be made payable to the Wyoming Secretary of State.
  • A written request for apostilles or certifications should include the name of the country where the document is destined to assure proper authentication. For your convenience, you may utilize this form.
