Notarial acts are legally significant actions performed by notaries, officials of executive authorities, and consular officers. Depending on the legal system in the country, the functions of notaries may have differences in the scope of authority and professional requirements.

As specially authorized individuals, notaries carry out legal certification of the authenticity of document copies, signatures, translations of documents into another language, and authenticate transactions. They also handle matters related to inheritance, wills, statements of individuals and legal entities, and other actions in accordance with local Notary Legislation.

The Lawyers Council of Thailand regulates the functioning of notarial services and empowers practicing lawyers to perform notarial acts.

Thailand is not a party to the Hague Convention “Abolishing the Requirement of Legalization for Foreign Public Documents,” so in some cases, legal acts are legalized through the Ministry of Foreign Affairs or the Consular representatives of the countries of origin of the documents.
