State Fee: $25 per apostille document.

What is an Apostille?

Not every document can be apostilled. Apostilles apply only to public documents: records originating from or certified by a government institution. Marriage Certificates fall into this category because it originates from a government agency. Business agreements and private records generally cannot be apostilled unless prior notarization is obtained.

The apostille certificate itself is formatted to a strict international standard with specific numbered data fields verifiable by foreign authorities worldwide. The Oklahoma Secretary of State in Oklahoma City attaches this certificate as a cover to your document. Since it is standardized, foreign governments can verify it immediately.

Many people in Duncan confuse an apostille with a notarization. The two serve entirely different purposes. A notary stamp only verifies that the person who signed the document is who they claim to be. It is not recognized by foreign governments as document authentication. An apostille, on the other hand, is an internationally standardized certificate accepted in all Hague Convention member countries certifying that the document's seals and signatures are legitimate.

State vs. Federal Apostille: Which Applies to Your Marriage Certificate?

The Global Apostille Network manages both state and federal apostille submissions: state-level apostilles through the Oklahoma Secretary of State in Oklahoma City. Once you submit your documents, we identify whether your Marriage Certificate is state or federal and route it to the right office. Duncan-based clients do not need to navigate the state vs federal distinction themselves.

If you have a deadline, expedited apostille service may be available. The Oklahoma Secretary of State in Oklahoma City have expedited tracks for urgent requests. Our courier uses these expedited tracks by submitting in person rather than by mail, which is typically the only way to access same-day or next-day processing.

A frequent and expensive error is submitting your Marriage Certificate to the wrong office. If you send a state Marriage Certificate to Washington D.C., the federal office will refuse to process it. In reverse, mailing a federal document to a state Secretary of State office will also come back unprocessed. In both cases, the round-trip postal time sets your application back by weeks.

Why a Local Notary in Duncan Cannot Apostille Your Document

That said: a notary stamp can be a precursor to the apostille process. Many document types must be notarized before the apostille can be attached. Diplomas, affidavits, powers of attorney, and some corporate documents often must be notarized before being submitted to the Oklahoma Secretary of State. For these documents, a Duncan notary handles step one and the Oklahoma Secretary of State completes the apostille.

The Oklahoma Secretary of State in Oklahoma City is not a walk-in office open to the public without advance planning. In Oklahoma, mail-in submissions sent from Duncan add 2 to 4 business days of transit each way before processing starts. Our runner service eliminates this transit time and can secure same-day or next-day processing not available to mail-in submissions.

The reason local notaries in Duncan cannot issue apostilles comes down to what a notary public is legally empowered to do. A notary is a licensed state officer authorized solely to witness signatures, administer oaths, and certify copies. A notary is not empowered to issue Hague certificates. Apostilles require the specific authority vested in the Oklahoma Secretary of State — a power not delegated to notaries.

Common Apostille Mistakes Duncan Residents Make

This adds 2 to 4 weeks — the time lost in transit to and from the wrong authority — before you are even back to square one.

A subtle but costly error is submitting a document that has been altered. If your Marriage Certificate shows any signs of modification or handwritten additions, it will likely be turned away.
