Need to use an Oklahoma document in a foreign country? Whether you're getting married abroad, adopting a child internationally, or expanding your business overseas, you'll likely need an apostille — a certificate that authenticates your document for use in countries that are members of the Hague Apostille Convention.
This guide walks you through the entire Oklahoma apostille process step by step, including what documents qualify, how much it costs, common mistakes to avoid, and how Just Legal Solutions can help.
Quick Answer: How to Get an Apostille in Oklahoma

The Oklahoma Secretary of State's office at 421 NW 13th St, Suite 210, Oklahoma City issues apostilles for documents used in 120+ Hague Convention countries.
What Is an Apostille?
An apostille is a certificate that authenticates the origin of a public document — such as a birth certificate, court order, or notarized document — for use in foreign countries that are members of the Hague Apostille Convention.
The apostille certifies three things:
- The authenticity of the signature on the document
- The capacity in which the person signing acted
- The identity of any seal or stamp the document bears
Important: An apostille does NOT certify the content of the document — only the authenticity of the signature and seal. The Hague Convention, established in 1961, simplified international document authentication by replacing the old chain-of-certifications process with a single apostille certificate. Over 120 countries are now members.
When Do You Need an Apostille?
You need an Oklahoma apostille when you have a document issued or notarized in Oklahoma that must be used in a Hague Convention member country.

Step-by-Step Oklahoma Apostille Process
Step 1: Prepare Your Document
For vital records: Obtain a certified copy from the appropriate authority — OSDH for birth/death certificates, county court clerk for marriage certificates, district court for divorce decrees.
For notarized documents: Have your document notarized by an Oklahoma notary public. Ensure the notarization includes a complete notarial certificate (acknowledgment or jurat), notary signature, clear seal/stamp, and commission information.
For court documents: Obtain a certified copy from the court clerk with the court seal and clerk signature.
Step 2: Complete the Request Form
Download and complete the Request for Apostille/Certificate of Authentication form from the Oklahoma Secretary of State website. You'll need: the destination country, your contact information, document type and description, number of apostilles requested.
Step 3: Prepare Your Submission
Include:
- Original document(s) to be apostilled
- Completed request form
- Payment: $25 per apostille (check or money order payable to "Oklahoma Secretary of State")
- Prepaid return envelope (if mailing)

Processing Timeline
Common Mistakes That Delay Your Apostille
Avoid These Errors
- 1. Submitting photocopies instead of certified copies — Vital records must be certified originals from the issuing authority.
- 2. Using an out-of-state notary — Oklahoma's Secretary of State can only apostille documents notarized by Oklahoma notaries.
- 3. Incomplete notarization — Missing seals, signatures, or notarial certificates will cause rejection.
- 4. Expired notary commission — Check that your notary's commission was current at the time of notarization.
- 5. Sending federal documents to the state — FBI background checks and federal court documents must go through the U.S. Department of State in Washington, D.C.
- 6. Requesting an apostille for a non-Hague country — Countries like China, UAE, and Saudi Arabia require embassy legalization instead.
- 7. Forgetting the return envelope — Mail-in requests need a prepaid return envelope or your documents may be held.
Apostille vs. Embassy Legalization
Not all countries accept apostilles. If your destination country is NOT a member of the Hague Convention, you'll need embassy or consulate legalization instead — a more complex, multi-step process:
- Notarize the document (if needed)
- Authenticate through the Oklahoma Secretary of State
- Authenticate through the U.S. Department of State
- Legalize at the destination country's embassy or consulate
Notable non-Hague countries: China, United Arab Emirates, Saudi Arabia, Egypt, Vietnam, Qatar, and Canada (for some document types).
