To get an Oklahoma apostille, submit your original or certified document to the Oklahoma Secretary of State in Oklahoma City with a $25 fee per document and the name of the country where the document will be used. Walk-in requests are handled the same day during business hours; mailed requests are typically processed within two to three business days of arrival. The certificate authenticates an Oklahoma official’s or notary’s signature so the document is accepted in countries that belong to the Hague Apostille Convention.1Hague Conference on Private International Law.

Which Documents Qualify
Oklahoma documents divide into two groups, and the group determines what you have to do before the Secretary of State will touch the paperwork.
State-Issued Records
A document that already carries the signature or seal of an Oklahoma state official can go straight to the Secretary of State. Certified copies of Oklahoma birth and death certificates from the Oklahoma State Department of Health are the most common example.2Oklahoma.gov. Vital Records FAQs – Birth and Death Certificates Marriage certificates, court orders, and certified copies of business filings from the Secretary of State’s office qualify the same way. The document must be an original or a certified copy issued by the agency; a plain photocopy will not do.
Private Documents
Anything that does not already carry a state official’s signature has to be notarized by a licensed Oklahoma notary first. That covers powers of attorney, affidavits, company bylaws, operating agreements, commercial invoices, school transcripts, university diplomas, and personal letters of authorization. When the Secretary of State issues the apostille, it is authenticating the notary’s signature, not the underlying signer’s. So the notarization has to be current, legible, and in original ink.
Educational records work through the same channel. A diploma or transcript is signed by the school registrar or another designated official, and that signature is then notarized by an Oklahoma notary. The apostille attaches to the notary’s act. A document signed by someone who is neither an Oklahoma state official nor a notary will be rejected.
What Oklahoma Cannot Apostille
Federal documents fall outside the Secretary of State’s authority. FBI background checks, U.S. passports, and records from federal agencies must be authenticated by the U.S. Department of State in Washington, D.C. Documents issued by another state must be apostilled by that state’s Secretary of State. An Oklahoma birth certificate goes through Oklahoma; a Texas birth certificate goes through Texas, no matter where you live now.
Fee
The fee is $25 per document. Five documents run $125. That rate applies whether you need an apostille for a Hague country or a certification for a non-Hague country. Payment is accepted by personal check, cashier’s check, or money order payable to the Oklahoma Secretary of State. Credit card payments are accepted, though a convenience fee may apply.
How to Submit
You can walk your documents in or send them by mail. Either way you need the original or certified document, payment, your contact information, and the name of the destination country. The country matters because it determines whether you get an apostille or a certification.
In Person
Walk-in requests at the Oklahoma City office are processed the same day during regular business hours, and no appointment is needed. Anyone can bring the documents in on your behalf, whether that is a family member, a friend, or a professional service.
By Mail
For mailed requests, send the documents with payment and a cover note that states the destination country and your return contact details. The request form is available on the Secretary of State’s website at sos.ok.gov. Include a pre-paid, pre-addressed return envelope if you want the documents sent back a specific way or to a specific address; without one, they go back by standard U.S. Postal Service. Confirm the current mailing address on the Secretary of State’s website before sending. Mailed requests are typically processed within two to three business days of arrival, so build in transit time on both ends when you plan around a deadline.
If the Destination Is Not a Hague Country
When the destination country has not joined the Hague Apostille Convention, the Secretary of State issues a certification rather than an apostille. The state fee is still $25 per document, but the certification by itself is not enough. Two more steps follow: authentication by the U.S. Department of State’s Office of Authentications in Washington, D.C., and then legalization by the embassy or consulate of the destination country.3Hague Conference on Private International Law.

Mistakes That Get Requests Rejected
- Expired or illegible notary seal. Verify the stamp is clear and that the notary’s commission was active on the date of notarization.
- Photocopied signatures. Only originals qualify. Multiple copies each need their own original notarization.
- Wrong jurisdiction. Documents from another state or a federal agency cannot be handled in Oklahoma.
- Missing destination country. Leaving the country off the request can send the whole package back unprocessed.
- Insufficient payment. Working from outdated fee figures results in a deficiency notice and delays.
After You Receive It
The apostille certificate is physically attached to your document. Leave it attached. Separating the certificate from the document invalidates it, and foreign authorities will not accept a loose certificate paired back up later.
If the receiving country needs the document in a language other than English, you will need a certified translation. Some countries also impose their own rules on top of the apostille, such as specific formatting or registration with a local authority after arrival. The apostille confirms authenticity; each country still sets its own rules for what it accepts in practice, so check with the destination country’s embassy or consulate before you ship or travel.
