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

Rayong hosts one of Thailand’s largest petrochemical and manufacturing bases and sits within the Eastern Economic Corridor. Legal work centres on contracts between manufacturers and contractors, employment of both permanent staff and subcontracted labour, promoted-investment conditions, permitting and administrative challenges, and documentation for foreign executives posted locally.
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 |
|---|---|
| Rayong Provincial Court and Rayong Municipal Court | Civil and criminal cases within the province |
| Rayong Juvenile and Family Court | Family and juvenile matters |
| Labour Court Region 2 | Labour cases across the eastern region |
| Rayong Labour Protection and Welfare Office | Labour complaints and workplace safety matters |
| Rayong Provincial Land Office and branch offices | Land, condominium and lease registration |
| Rayong Immigration Office | Extensions of stay and foreign-national matters for industrial personnel |
| Rayong Legal Execution Office | Enforcement of judgments in the province |
| Rayong 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 Rayong.
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.)

Labour protection law can make the principal jointly liable with a subcontractor for wages and statutory payments in certain cases. The practical safeguard is a contractual requirement to show proof of wage payment before each instalment is released, with records of those checks kept every period.
First check whether the order states its reasons and appeal rights, since administrative procedure law requires reasons. Then note the internal appeal deadline and the deadline for filing in the Administrative Court — missing them forfeits the right even where the substance is arguable.
Three elements must align: work authorisation under foreign-worker law, the extension of stay under immigration law, and the employment terms in the contract and any investment-promotion conditions. All three must state the same position and workplace, or renewal filings will be sent back for correction.
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.
