How do we get head-office documents accepted in Thailand?
Short answer
Foreign corporate documents generally need certification in the country of origin followed by either an Apostille — available for Contracting Parties since the Convention entered into force for Thailand on 22 December 2024 — or the older legalisation chain, plus a Thai translation for the receiving office.
Confirm with the Thai receiving office which documents it wants certified. Certifying the whole corporate book when only the certificate of incorporation and the board resolution are needed wastes weeks.
Keep the certified set current: several Thai offices will not accept corporate documents beyond a certain age.
