How the work proceeds

    1. Draft review: send the draft so our staff can confirm the format required in United States.

    2. Signing before the notarial attorney: bring your original ID or passport.

    3. Department of Consular Affairs legalisation: according to its current procedure and queue.

    4. United States Embassy legalisation (if required): according to the embassy's conditions.

    5. Collection or courier: our staff confirm each step once actual appointments are known.

Common problems before filing in United States

    1. Name spelling differs from the passport — check every character, including middle names.

    2. Translation not checked — some United States authorities require a English translation.

    3. Incomplete notarial details — the certificate should show the attorney's name, registration number, signature and seal.

    4. Missing legalisation step — notarisation alone may not be enough; confirm the receiving authority's requirements.

    5. Wrong procedure for the date — steps for Apostille countries may differ before and after 28 February 2027.

    6. Document too old — some authorities set a validity window; confirm with the receiving authority.

Quick answer — Signature Verification / Acknowledgment for use in United States

    Short answer: a Signature Verification / Acknowledgment certified by a Thai Notarial Services Attorney must complete the legalisation steps required by the receiving authority in United States.


    United States is a party to the Apostille Convention, but the Convention enters into force for Thailand only on 28 February 2027 (HCCH). Until then, Thai documents still need Department of Consular Affairs and embassy legalisation; after that date, check the current Apostille procedure with the Department of Consular Affairs.


    Timing: depends on Department of Consular Affairs and embassy queues — our staff confirm the schedule after reviewing your documents.

    Service fee: request a quotation from our staff. Government and embassy fees are paid at the rates those offices publish.

Q: Do I need a English translation?
A: English is generally accepted, but certain United States authorities still require English.
Q: Does United States accept e-Apostille (digital)?
A: Ask the receiving authority whether it accepts a digital Apostille or needs a paper original, and check the latest Department of Consular Affairs guidance.
Q: How long does it take?
A: Turnaround depends on document type, volume and government office queues, which change over time. Confirm the delivery schedule in your quotation before work starts.
Q: Do I need to visit the office in person?
A: Only the notary signing step requires an in-person appearance (Bangkok on-site available). MFA and Embassy steps are handled by NYC on your behalf.
Q: What is the United States embassy fee?
A: Before 28 February 2027 embassy legalisation may still be required; embassy and government fees follow their published rates. Request a service quotation from our staff.
Q: Do I have to submit the passport original?
A: Only during the notary appointment (same-day return). MFA and embassy steps do not require the original passport.
Q: What if the courier loses the document?
A: We use tracked courier services. If a problem occurs, our staff explain the options and re-filing steps; cover follows the courier's terms.
Q: Is a Thai notarised document guaranteed to be accepted in United States?
A: A Notary + Apostille document cannot be guaranteed acceptance by anyone; the receiving authority in United States decides. Confirm its format requirements before filing.
