Frequently Asked Questions:
Document, Translation, and Notary Public Services

They serve different purposes. A notary public (notarial services attorney in Thailand) certifies the authenticity of signatures, document copies, or personal identity within Thailand. The Department of Consular Affairs authenticates the signature or seal of a government official or notary, enabling documents to be used officially abroad. For international use, a notarized document typically must be legalized by the Department of Consular Affairs afterward (always verify the destination country’s requirements).

It depends on the purpose and receiving authority. For internal use or general reference, additional certification may not be required. However, if the translated document will be submitted to government agencies, courts, embassies, or used abroad, it typically requires notarization of the translator’s signature by a notary public and/or legalization by the Department of Consular Affairs. OSP LEGAL can advise and handle both steps.

(1) the original document to be notarized
(2) a valid ID card or passport of the relevant party (e.g., the signatory or document owner). An in-person appearance is required for signature witnessing, as the signatory must sign before the notary public. For other notary services, such as a certified true copy, a power of attorney may be used; consult us for specific cases.

Notarization and legalization serve distinct functions. A notary public in Thailand certifies signatures, copies of documents, or personal identity for use within Thailand. The Department of Consular Affairs authenticates the signature or seal of a government official or notary, allowing documents to be recognized abroad. For international use, a notarized document must usually be legalized by the Department of Consular Affairs. Always confirm the requirements of the destination country.

Requirements depend on the document’s purpose and the receiving authority. For internal use or general reference, further certification is often unnecessary. However, if the translation will be submitted to government agencies, courts, embassies, or used abroad, notarization of the translator’s signature and/or legalization by the Department of Consular Affairs is typically required. OSP LEGAL can advise you and manage both processes.

An in-person appearance is required for signature witnessing, as the signatory must sign in front of the notary public.
