Civil and Commercial Code
Book VI: statutory heirs, shares, will formalities and appointment of an estate administrator.
Southern Thailand — Surat Thani
Drafting wills that hold up, and administering estates correctly under Thai law.

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.
Estate planning in Thailand involves the recognised will formats, the rights of statutory heirs, registered assets such as land and condominium units, and the position of foreign nationals holding assets both in Thailand and abroad. We draft wills, advise on structuring, petition the court to appoint an estate administrator, and complete the transfer of estate assets.
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 |
Drafting and executing a will is quick once the asset list is complete; appointing an administrator and transferring assets runs through the court and takes months, depending on the docket and any heir objections.
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 VI: statutory heirs, shares, will formalities and appointment of an estate administrator.
Wills may take several statutory forms; using the wrong formality can void the will.
Foreign land-holding limits affect foreign heirs inheriting land.
These are constructed examples used to explain procedure. They are not client matters, and no outcome is implied or guaranteed.
Situation: Heirs hold the death certificate and house registration, but the bank requires a court-appointed administrator.
Usual approach: The usual route is petitioning the competent court for an administrator with an estate inventory and heirs’ consents, then presenting the order to banks and registries. (Hypothetical.)

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.
Yes, and a separate Thai will covering Thai assets is often advisable so that local administration proceeds quickly without conflicting with a will made elsewhere.
The estate passes to statutory heirs in the order the law prescribes, which may not match the deceased’s wishes and often takes longer because of disputes.
Land law imposes restrictions, generally requiring disposal within a set period. We explain the options available on the family’s actual facts.
Tell us the facts and we will explain which authority applies, what documents are needed and the realistic timeframe.
