BOI & Foreign Business Setup Lawyer in Chai Nat — 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 Chai Nat
Chai Nat is a rice and agriculture province in the Chao Phraya basin — home to the Chao Phraya Dam (the major barrage that distributes irrigation water across the Central plains), the Chai Nat Bird Park, and river logistics along the Chao Phraya, Noi, and Tha Chin rivers. Matters here often involve land, agriculture, irrigation water rights, rice and produce sale contracts, and civil, criminal, and family litigation. We handle land and inheritance disputes, business contracts, and general cases from our Bangkok branch.
Chai Nat is a Central-region province close to Bangkok, so our Bangkok branch (Lat Phrao) can attend court and coordinate with local agencies conveniently. As a firm with 40+ years' experience, we understand land and inheritance disputes across farming districts, irrigation water rights tied to the Chao Phraya Dam, and rice and produce sale contracts — with multilingual service for clients and investors, and we travel to provincial courts nationwide.
