Thailand has not joined the Hague Convention. Thai documents going abroad need Thailand MOFA + destination Embassy chain. Foreign documents into Thailand need Thai Embassy legalization from origin country.
Step 1 of 4
What is your situation?
Thailand is one of Southeast Asia's major non-Hague countries. Unlike neighboring China (which joined Hague in 2023), Thailand continues to require full consular legalization for all document authentication needs — in both directions.
Thai workers going to South Korea, Japan, and other countries under bilateral labor agreements need Thailand MOFA legalization + Embassy of destination country.
Foreign companies registering with Thailand's DBD or under BOI promotion need Thai Embassy-legalized corporate documents from their home country.
Foreign nationals marrying Thai nationals need personal status documents legalized through the Royal Thai Embassy in their home country.

China joining the Hague Convention in 2023 doesn't change Thailand's own non-Hague status. Vietnamese or Thai documents still require consular legalization chains regardless of what neighboring countries have done.
