Documents Oklahoma can apostille

Notarized original documents (Oklahoma notary)
Certified copies of original documents
Certified recorded instruments such as birth certificates, marriage licenses and divorce decrees
Court-certified documents

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.

Common questions

How much does an Oklahoma apostille cost through Trilogy?

Our Oklahoma apostille service starts at $355 per document. That price includes the Oklahoma 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 Oklahoma?

The Oklahoma Secretary of State, Certification Department. 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 Oklahoma require before it will apostille a document?

An apostille is attached only to a notarized original document or a certified copy of an original document. Certified court documents (including marriage licenses and divorce decrees) must be dated within one year of submission; a current copy comes from the Court Clerk in the issuing county. We check for these before anything is filed.

Can Oklahoma 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 Oklahoma 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, Oklahoma issues this instead of a standard apostille: Certificate of Signature. 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 an Oklahoma apostille take?

The Oklahoma Secretary of State does not publish a standard processing time. Total time depends on the state's queue plus shipping both ways. We confirm current timing when we review your order, and we don't promise a delivery date we don't control.
