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 the document is a vital records document (birth certificate, marriage license, etc), you may contact any county Register of Deeds OR South Dakota Department of Health - Vital Records 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 and request form.
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, by emailing apostille@state.sd.us or calling (605) 773-5004 to notify our office that you are on your way.
