Thai Consular Legalization is an important administrative procedure that helps you legalize documents and papers in Vietnam for lawful use in Thailand, or vice versa. This process can be complex and requires understanding of legal regulations as well as procedural steps. In this article, No.1 Translation will provide detailed information about the Thai consular legalization procedure and a full-service package to help you complete the process quickly and accurately.
What is Thai Consular Legalization and Certification?
Thai Consular Certification and Legalization are two important steps in the process of legalizing documents between the two countries, ensuring that papers issued in Vietnam can be legally used in Thailand, and vice versa.
Thai Consular Certification
Consular certification is the first step in the legalization process, aimed at verifying the signature, seal, and position of the signatory on a document or paper. This step is carried out by the competent diplomatic authority of the country that issued the document, with the purpose of ensuring that the document can be legally used in another country.
For Vietnam, the authorities competent to provide consular certification include:
- Hanoi Department of Consular Affairs.
- The Department of External Relations in Ho Chi Minh City.

Thai Consular Legalization
After the documents have been certified, the next step is consular legalization. The Thai Embassy or Consulate will review and confirm the legality of the signatures and seals on the documents, ensuring that they are accepted for use in Thailand.
The authorities competent to carry out consular legalization in Thailand are:
- The Thai Embassy in Hanoi.
- The Royal Thai Consulate General in Ho Chi Minh City.
Similarly, in Vietnam, the authorities competent for consular legalization are:
- The Embassy/Consulate General of Vietnam in Thailand, or
- The Ministry of Foreign Affairs of Vietnam if the consular legalization is conducted in Vietnam.
