Northern Thailand — Chiang Rai
Incorporation, contracts, foreign business, BOI and compliance

Chiang Rai borders both Myanmar and Lao PDR and combines border trade, highland agriculture, tourism and a growing foreign-resident community. Legal work includes cross-border trade and transport contracts, land disputes in use-restricted areas, and civil-status matters for people with incomplete registry records, which require careful historical document review.
Full-lifecycle corporate support: choosing the right vehicle, incorporation, drafting and reviewing contracts, foreign shareholding structures, business licensing, M&A and dissolution.
Jurisdiction and filing requirements should be confirmed for each matter, because practice and required attachments differ between offices.

Book III governs company formation, directors’ powers, shareholder meetings and share transfers.
Restricts certain businesses for foreigners and sets out the licensing route.
The basis for BOI tax and non-tax incentives.
Sets corporate tax duties, withholding tax and VAT obligations.
These are constructed examples used to explain procedure. They are not client matters, and no outcome is implied or guaranteed.
Situation: A foreign investor wants more than 49% of a service business.
Usual approach: Check whether the activity falls in the FBA schedules, then compare a foreign business licence, BOI promotion, or restructuring the activity outside the restriction. (Hypothetical.)
Situation: A director resigned but the company never filed the change.
Usual approach: Keep dated proof of the resignation and push the registration through — stale register data can be used to assert liability later.

Whichever the contract designates. Without a clause, it becomes a question of interpreting the parties’ intent — slow and uncertain. The fix is a clause naming the governing version and treating the other as a convenience translation.
Verify whether the title type is transferable, whether the plot lies in a use-restricted zone, how actual boundaries compare with the cadastral map, and whether access is a legal right or merely permitted by consent — these affect both building and resale.
Yes, through the registrar’s procedure, supported by historical evidence and sometimes witnesses. Where evidence is insufficient, a court order confirming the facts may be needed first, so all older documents should be gathered before starting.
Activities listed under the Foreign Business Act generally require majority Thai ownership unless a licence, treaty right or BOI promotion applies.
Not universally required by law, but some licences and banking practices call for one.
English contracts are binding, but a certified Thai translation is needed for Thai courts or authorities.
