Oklahoma apostille service for birth, court and school records

Who issues apostilles in Oklahoma

The Oklahoma Secretary of State issues every apostille and authentication for Oklahoma documents. Its Certification Department attaches the certificate to an original notarized document or to a certified copy of a recordable document issued by an Oklahoma statewide officer, and chooses between the two certificates based on the country you name.

The department works from Suite 210 of the Colcord Center, 421 NW 13th Street, Oklahoma City, and takes calls at (405) 521-4211. Its apostille page gives weekday hours from 8:00 AM until 4:30 PM. A mailed request must include a cover letter naming the country that needs the document, along with a valid phone number or email address.

Countries in the Hague Apostille Convention receive an apostille. Countries outside it receive an authentication, which must then be certified by the U.S. Department of State and legalized by the destination's embassy. Our explainer on apostille, authentication and legalization sets out the difference, and the Hague country list tells you which one you need.

Records created by federal agencies are outside the state's reach. An FBI Identity History Summary, a naturalization certificate or an IRS letter can only be handled at the federal level, by the U.S. Department of State, which is the path our FBI report apostille service takes.

Oklahoma documents we apostille

The Oklahoma Secretary of State names birth certificates, marriage licenses, divorce decrees, background checks, powers of attorney, survivor certificates, school transcripts and adoption documents among the papers it certifies. Each one starts at a different Oklahoma office, and that office's signature is what the apostille confirms.

• Birth and death certificates: certified copies from Vital Records at the Oklahoma State Department of Health. Read more about apostilles for birth certificates and apostilles for death certificates.
• Marriage licenses: issued and certified by the court clerk in the county where the license was obtained. Our marriage certificate apostille page has more detail.
• Divorce decrees and other court records: certified by the court clerk in the county where the case was filed. Our divorce decree apostille page covers what foreign registries ask for.
• Powers of attorney and affidavits: signed before an Oklahoma notary public, then apostilled on the notary's signature. Read about apostilles for a power of attorney.
• Survivor certificates: also on the state's list. We confirm who needs to sign yours before you send it.
• School transcripts and diplomas: the state lists transcripts by name. A registrar is not a statewide officer, so plan on a notarized signature. Transcript questions are covered on our diploma and transcript apostille page.
• Background checks: an Oklahoma background check is on the state's list. An FBI check is not, because it is a federal record.
• Business records: a certificate of good standing ($20 from the Secretary of State) or certified copies of business filings. Companies opening accounts or subsidiaries abroad can read about our apostilles for corporate documents.
• Adoption documents: eligible for the reduced $10 apostille when used in an international adoption.

Holding something that is not on this list, such as a deed or a professional license? Send us a photo. We will tell you whether Oklahoma can certify it as it stands, or whether it first needs a notarized signature or a certified copy from the office that keeps the original.

Oklahoma requirements that trip people up

In Oklahoma the date on a court certification matters as much as the document. The Secretary of State asks that marriage licenses, divorce decrees and any other court-certified document be dated within the past year. Payment is the other snag, because mailed requests paid by personal check are not accepted.

Fresh court copies

In practice the date that counts is the clerk's certification, not your wedding day or the date of the decree. A certified copy ordered this month from the court clerk can cover a marriage from the 1980s. The Secretary of State's page sends you to the County Court Clerk's office that issued the document for a current certified copy, so ask for a certified copy there, not a plain photocopy.

Notarized papers

Oklahoma apostilles an original notarized document directly, with no county certification in between. Make sure the notarial certificate is complete and the notary is commissioned in Oklahoma. Identity documents follow the same path: a copy of your passport or driver's license, properly notarized by an Oklahoma notary, can carry an Oklahoma apostille, as our page on passport copy apostilles explains. Federal records do not: a notarized copy of an FBI check, a naturalization certificate or a USCIS notice will not replace the federal route.

Paying the state

Mailed requests need a certified cashier's check, money order or business check payable to the Oklahoma Secretary of State. In person you can also pay cash or use a card, with the 4% fee.

Getting a certified copy in Oklahoma

Oklahoma birth and death certificates come from Vital Records at the Oklahoma State Department of Health. The fee is $20 for the first certified copy and $15 for each additional copy. Online and phone orders take about two business days, while mailed applications take about six weeks.

You can order online through VitalChek, by phone at (405) 426-8880, by mail to the department's post office box in Oklahoma City, or through Will Call pickup in Oklahoma City, Tulsa and McAlester, open from noon to 4:45 PM on weekdays. Orders can be expedited for an extra fee. Eligible applicants include the person on the record, named parents, legal representatives and others acting in that person's best interest who can document it. The Oklahoma Vital Records FAQ has the current ordering details.

Marriage and divorce records work differently in Oklahoma. They are court records, held by the court clerk where the license was issued or the case decided, so order those copies from the county and keep the one-year certification rule in mind. If your certificates are for a move overseas, our guide for Americans living abroad shows how they fit a residency file.

How long an Oklahoma apostille takes

As of September 2026, the Oklahoma Secretary of State does not post a processing time on its apostille page. The delays you can avoid are the ones visible before filing: a court certification older than a year, a personal check on a mailed request, or a request sent without a cover letter.

Once your document is ready, Economy takes 1 to 3 weeks with us. Express, at 1 to 5 business days in most states, is the faster option, and we confirm the Oklahoma estimate during your free review. A new certified copy comes first when you need one: a mailed birth certificate order can take about six weeks on its own, while an online or phone order through VitalChek takes about two business days. County court clerks set their own pace for certified copies. Rush service the same day is something we offer only for Massachusetts and New Hampshire documents.

What an Oklahoma apostille costs

Oklahoma's state fee is $25 per apostille, $10 for an apostille used in an international adoption and $20 per authentication for non-Hague countries. Our Economy package costs $149.95 and Express costs $199.95, and the Oklahoma fee is already inside both prices, so there is no separate check to the state.

Because the state fee is part of our price, the 4% card surcharge and the ban on personal checks become our problem instead of yours. Extras depend on your file: a certified translation if your destination wants one, a courier upgrade for the return, and embassy legalization for non-Hague countries such as Qatar or Kuwait, which we quote country by country before you pay. Ordering for the whole family or a batch of company records? Ask us about a volume discount, and see every option on our apostille services page.

Getting an Oklahoma apostille without visiting Oklahoma City

You can get an Oklahoma apostille without a trip to the Colcord Center. Send the document to our office in Tewksbury, Massachusetts, or have the court clerk or the health department mail a fresh certified copy to us, and we take it from there.

That helps people from Tulsa, Norman, Edmond, Broken Arrow or Lawton who have since moved away, and service members who married in Oklahoma while stationed there and now need the license recognized abroad. We look at a scan or photo first, confirm whether the destination needs an apostille or an authentication, and only then file. If the court clerk in your county is hard to reach from overseas, tell us the county and we will explain how to request the copy. Papers from Texas or another state can join the same order.
