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

Udon Thani is the gateway between the upper northeast and Lao PDR, with a sizeable community of foreign nationals married to Thai spouses and living long term. Work here mixes local land and succession disputes with marriage registration, bilingual wills and documents for use in a spouse’s home country. Preparing documents for both systems at the outset avoids repeating the process.
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.

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 Udon Thani.

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.)

Typically the marriage certificate, the spouse’s house registration and ID card, proof of residence and financial evidence under Immigration Bureau criteria. The most frequent cause of resubmission is names or dates differing between documents, so consistency should be checked before filing.
Use a form of will recognised under Thai law and state clearly whether it covers only Thai assets or foreign assets too. If a will already exists in the home country, the wording must avoid unintentionally revoking it — a common problem when two wills are made separately.
The main risks concern the asset’s status on divorce or death, and the requirement that officials may ask to confirm the source of funds as the Thai spouse’s personal property. Recording intentions and conditions in advance, in a form valid under Thai law, reduces later disputes far more than reacting afterwards.
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.
