The Office of the Secretary of State provides authentication and apostille service to U.S. citizens and foreign nationals on all documents that will be used overseas. Types of documents include corporate documents such as company bylaws and articles of incorporation, power of attorney, patent applications and trademarks, diplomas, transcripts, letters relating to degrees, marital status, references and job certifications, home studies, deeds of assignments, distributorship agreements, papers for adoption purposes, etc.
If you would rather complete the Apostille / Certificate of Authentication Request form instead of a cover letter, click here.
If the document is a vital records document (birth certificate, marriage license, etc), you may contact any county Register of Deeds office or the State Department of Health (605-773-4961) and request a certified copy of that document; then submit the certified copy to the Office of the Secretary of State with the filing fee of $25.00 per document.
Most documents will be processed and mailed on the day they are received. You may also visit the Office of the Secretary of State to have the documents processed. However, please contact the Apostille Administrator, (email address: firstname.lastname@example.org) to make an appointment, so that help is available when you arrive. You may call 605-773-2797.Further Contact Information:
More information on apostilles and authentications is available through the U.S. State Department Office of Authentication by phone (202) 647-5002 or website (http://www.state.gov/m/a/auth).
