Civil and Commercial Code
Book III governs company formation, directors’ powers, shareholder meetings and share transfers.

Southern Thailand — Surat Thani
Incorporation, contracts, foreign business, BOI and compliance

Surat Thani contains two distinct settings: a mainland centre for agriculture and commerce, and the islands of Samui, Phangan and Tao where tourism and foreign investment drive the economy. Legal work differs accordingly, from crop-sale and agricultural land contracts to hotel leases, condominium transactions and documentation for foreign residents on the islands.
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.
| Court / authority | What it handles |
|---|---|
| Surat Thani Provincial Court, Koh Samui Provincial Court and Surat Thani Municipal Court | Civil and criminal cases by jurisdiction, with the islands served by their own provincial court |
| Surat Thani Juvenile and Family Court | Family and juvenile matters |
| Labour Court Region 8 | Labour cases in the upper southern region |
| Surat Thani Provincial Land Office and branch offices, including the Koh Samui branch | Land, condominium and lease registration on the mainland and islands |
| Surat Thani Immigration Office and Koh Samui immigration checkpoint | Extensions of stay and residence notification for foreign nationals |
| Surat Thani Legal Execution Office | Enforcement of judgments in the province |
| Surat Thani Provincial Commercial Office | Local company registration services |
Incorporation with complete documents usually takes a few business days; special licences and BOI approvals take considerably longer.
Timeframes are indicative and depend on the court calendar and the authority handling the matter in Surat Thani.
Summarised for general understanding only. The application of each provision depends on the facts of your case.
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.

Not necessarily — Koh Samui Provincial Court has its own jurisdiction. Venue follows the defendant’s domicile and where the cause of action arose; if both are on the island, the case can be filed there directly.
Check whether the lease is registered, the remaining term, whether the leasehold can be assigned to the buyer, renewal conditions, and the accommodation licence, which attaches to both the building and the operator. If the leasehold cannot be assigned, the agreed price may not reflect what the buyer actually receives.
Yes, but the document must be designed to the receiving authority’s requirements from the outset — language, form of signature certification and the order of certification — because corrections usually mean restarting the whole process, which costs more time on an island.
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.
