In a bilingual Thai lease, which language version prevails?
Short answer
Whichever version the contract itself names as controlling — and if it names none, a Thai court works from the Thai text, because Thai is the language of the proceedings and any foreign-language document must be filed with a certified Thai translation.
So the prevailing-language clause is not boilerplate. Decide it consciously, state it in both versions in identical terms, and make sure the two texts actually match before signing. The common failure is a landlord's Thai text carrying a deposit-forfeiture or early-termination term that the English courtesy translation quietly softens.
Two practical points. First, have the Thai version read by someone who can compare clause by clause, not summarised. Second, a lease of more than three years must be registered at the Land Office to be enforceable beyond three years, so a long lease with a beautifully drafted prevailing-language clause and no registration still fails at year four.
