BOI & Foreign Business Setup Lawyer in Chanthaburi — Incorporation, FBL, Treaty of Amity, EEC
Setting up a foreign-controlled business in Thailand routes through one of several systems: a Thai limited company with up to 49% foreign ownership (the default under the Foreign Business Act), a BOI-promoted company that can be 100% foreign-owned for promoted activities, a Foreign Business Licence (FBL) for activities outside BOI scope, the US Treaty of Amity (for US persons), or an EEC-zone structure. Each carries different timelines, costs, tax positions, and ongoing reporting. We help foreign investors pick the right path before anyone signs a lease, and we then run the incorporation and post-incorporation compliance.

About our team in Chanthaburi
Chanthaburi runs two economies that generate their own disputes: a gem and jewellery market where high-value trades still rest on trust more than paperwork, and export orchards — durian above all — where Chinese packing houses and exporters buy at the grove. What follows is payment default, deposits, quality and grading disputes, and Cambodian border trade.
A trade done on trust is not an unenforceable trade — it means the case has to be built from the money trail, delivery records, and surrounding witnesses in place of the contract that does not exist. We have run this class of case for traders continuously. The team works in Thai, English, and Chinese, runs the file from our Khon Kaen head office and Bangkok branch, and travels to appear at the Chanthaburi Provincial Court.
