Documents South Dakota can apostille

Certified birth, marriage and death certificates
Divorce decrees and judgments
Official business documents filed with the Secretary of State
Documents notarized by a South Dakota notary (affidavits, agreements, powers of attorney, diplomas, transcripts, adoption home studies, income verification)
Notary-certified copies of a U.S. passport

The issuing state is what matters, not where you live now. A document issued or notarized in another state goes to that state's office, and documents from federal agencies go to the U.S. Department of State through our federal apostille service.

Our South Dakota apostille service starts at $370 per document. That price includes the South Dakota government fee of $25 per document, plus courier filing, return shipping, and handling. Sales tax, if it applies, and any deposit are shown at checkout before you pay.

Who issues apostilles in South Dakota?

The South Dakota Secretary of State, Apostille Office. Trilogy Notary Services is a private document services company: we prepare and submit your request and track it, but the apostille itself is issued by the state office.

What does South Dakota require before it will apostille a document?

State and local documents must bear the raised and/or stamped seal of the court or department of vital records. Other documents must be certified and/or notarized by a South Dakota notary public. We check for these before anything is filed.

Can South Dakota apostille an FBI background check or another federal document?

No. Documents issued and signed by a federal agency, such as an FBI background check, are authenticated by the U.S. Department of State, not by the South Dakota Secretary of State. We handle those through our federal apostille service.

What if my destination country is not in the Hague Apostille Convention?

For non-Hague countries, South Dakota issues this instead of a standard apostille: Certificate of Authentication. Many non-Hague countries then require embassy or consulate legalization, which we handle through our embassy legalization service. Tell us the destination country when you book.

How long does a South Dakota apostille take?

As published by the state when we checked on October 29, 2026: Mail: within 2 business days of receipt. Drop-off: most orders in 1-2 business days. Expedited appointment: processed while you wait when possible. Add time for document preparation and shipping both ways. Government processing times change and are outside our control, so we don't promise a delivery date.
