This article explores the significance of Notary Public services in Thailand, including their functions, legal implications, and the role they play in legalizing documents.

Role and Functions:

The primary function of a Notary Public in Thailand is to provide legal authentication and verification of documents, signatures, and copies. Notaries serve as impartial witnesses to the signing of documents and the affirmation of their authenticity. Their key functions include:

  1. Document Notarization: Notaries authenticate documents by affixing their official seal and signature. This process certifies that the document is genuine and legally binding.
  2. Verification of Signatures: Notaries verify the identity and authority of individuals signing documents, ensuring that the signatures are genuine and accurate.
  3. Witness to Affirmations: Notaries act as witnesses to affirmations, oaths, or acknowledgments made by parties in legal documents.
  4. Certification of Copies: Notaries can provide certified copies of original documents, verifying their authenticity for official purposes.
  5. Administering Oaths: Notaries have the authority to administer oaths and affirmations, which are often required in legal affidavits and declarations.

Legal Implications:

Notary Public services carry significant legal implications in Thailand:

  1. Document Credibility: A document notarized by a Notary Public is presumed to be genuine, which adds a layer of credibility and trust in legal transactions.
  2. International Recognition: Notarized documents often receive international recognition, facilitating cross-border transactions and legal processes.
  3. Legal Records: Notary Public services create a reliable record of the time and date of document execution, which can be crucial in case of disputes.

Types of Notarization:

Notarial Documents and Legalization:

Legalization involves obtaining official certifications from government authorities to verify the authenticity of notarized documents for use abroad. In Thailand, the process of legalization often includes:

  1. Ministry of Foreign Affairs: The Ministry of Foreign Affairs authenticates the signature and seal of the Notary Public.
