Federal vs. State: Oklahoma Specifics
The Oklahoma Secretary of State in Oklahoma City handles all apostille requests for documents originating in the Sooner State. Oklahoma requires documents to be either certified copies from a state or county agency, or notarized by an Oklahoma Notary Public. Oklahoma does not require county clerk pre-authentication for notarized documents. Vital records must be obtained from the Oklahoma State Department of Health, Vital Records Service. Court documents require certification from the Court Clerk of the issuing county. Oklahoma's energy sector generates significant apostille demand for international oil and gas transactions.
