Acquisitions

Buying a Business in Thailand: The Legal Steps

Published 6 Oct 2026

Buying a Thai business usually means buying the shares of the company that owns it, or buying its assets. For a share purchase, the transfer of registered shares is void unless made in writing, signed by seller and buyer, witnessed by at least one person and stating the share numbers, and it binds the company and third parties only once recorded in the shareholders' register (section 1129 of the Civil and Commercial Code). A foreign buyer also has to consider whether the purchase makes the company foreign under the Foreign Business Act.

Who this is for

Buyers of a Thai private company or business, including foreign buyers and investors taking a stake. Sellers will find the same points useful in preparing.

Foreign buyers

Under section 4 of the Foreign Business Act B.E. 2542, a Thai company is treated as foreign when foreigners hold 50% or more of its shares or capital. If the purchase crosses that line, the company's activities have to be checked against the Act's restricted lists before completion. Holding shares on a foreigner's behalf to avoid the Act is prohibited (section 36).
