Translation and legalization in Thailand documents are essential processes for foreigners and businesses dealing with official matters. Whether you are applying for a visa, work permit, business registration, marriage registration, or court proceedings, official documents issued in a foreign language must be translated into Thai and legalized to be recognized by Thai authorities. Similarly, Thai documents intended for use abroad must be translated and authenticated before they can be accepted by foreign governments or embassies.
The legalization process in Thailand is regulated by the Ministry of Foreign Affairs (MFA), the Thai Courts, and various government agencies. This guide provides an in-depth overview of legal translation requirements, certification procedures, government agencies involved, and best practices to ensure compliance with Thai laws.
1. Legal Framework for Translation and Legalization in Thailand
Translation and legalization in Thailand are governed by the following laws and regulations:
- Civil and Commercial Code of Thailand – Requires official documents to be in Thai language for use in legal and business transactions.
- Foreign Affairs Ministry Regulations on Document Authentication – Outlines the process for certifying translations of foreign documents.
- Consular Affairs Department of the Ministry of Foreign Affairs (MFA) – Oversees legalization of documents for international use.
- Notarial Services Attorney System – Lawyers licensed by the Thai Lawyers Council can notarize and certify translations.
- Hague Apostille Convention – Thailand is not a member, meaning that documents intended for use abroad require full legalization by the MFA and the relevant embassy.

4. The Process of Document Legalization in Thailand
To ensure that a foreign document is legally valid in Thailand, it must go through a three-step legalization process:
Step 1: Translation of Documents into Thai

✔ Some embassies may require notarization before accepting foreign documents.
Step 3: Legalization at the Ministry of Foreign Affairs (MFA)

✔ The MFA will verify the authenticity of the document and certify it for legal use in Thailand.
For documents intended for use abroad, an additional step is required:
