Apostille & Document Authentication in San Antonio, TX

Available 24/7 across San Antonio and all of Bexar County.

247Notary.pro helps San Antonio clients prepare documents for an apostille — the certification required before a U.S. document (birth certificate, diploma, power of attorney, corporate document) is recognized in another country under the Hague Convention.

How the apostille process actually works

The correct path depends on the document. Some private documents — powers of attorney, corporate resolutions, affidavits — must first be properly notarized in Texas with the acknowledgment language the destination country requires. Certified public records, including many Texas birth, death, marriage, court, and other official records, generally follow the issuing-authority or certified-copy process instead of being re-notarized. For eligible Texas documents, the Texas Secretary of State issues the apostille or authentication certificate — not us, and not any notary. An apostille authenticates the signature or seal of the applicable public official for use in another jurisdiction; it does not validate the truth or legal effect of the document's contents.

Before you book — what to check first

What country will receive the document? Is that country a Hague Apostille Convention participant? Is the document a private document (needs notarization first) or a certified public record (needs the issuing authority's own certified copy instead)? Who issued the document? Does the receiving agency specifically require an apostille, an authentication certificate, a certified translation, or something else? We can help you sort this out before your appointment so nothing gets rejected for the wrong process.

Common documents we help prepare

Birth and marriage certificates, single-status/no-record letters, diplomas and transcripts, powers of attorney for property abroad, corporate resolutions and articles of incorporation for business use overseas, and adoption or immigration-related paperwork.

How It Works

  1. Determine whether your document needs notarization first (private documents) or goes straight to certification (certified public records).
  2. We notarize your document if it requires it.
  3. You or we submit the document to the Texas Secretary of State for apostille certification.
  4. You receive your apostilled document, ready for international use.

Pricing

Our notarization fee is separate from the Texas Secretary of State's apostille filing fee — see our pricing page for the notarization side.

Frequently asked questions

Do you issue the apostille yourself?

No individual or notary issues the apostille itself — only the Texas Secretary of State can, for eligible Texas documents. What we do is notarize and prepare a private document so the Secretary of State's office accepts it without delay, and can advise on submission.

Can a notary certify a copy of my Texas birth or marriage certificate for an apostille?

No — Texas notaries cannot create a certified copy of a vital record. Certified public records like birth and marriage certificates come from the issuing authority (Texas Vital Statistics or the county) directly, not from a notary.

How fast can I get a document notarized for an apostille?

Same-day in most cases for documents that do need notarization first. Since we're a 24/7 mobile notary, we can meet you the same day, which is usually the bottleneck before submission to the Secretary of State.
