When a foreign national dies holding real estate assets in Thailand—whether a foreign freehold condominium unit, a registered 30-year leasehold, or a right of superficies—the succession of those assets does not occur automatically. Foreign probate decrees and overseas wills have no direct self-executing force in the Kingdom.
The transmission of real property upon death is controlled by the intersection of four distinct statutory regimes:
-
The Conflict of Laws Act B.E. 2481 (1938), which establishes the governing jurisdictional law for immovable property.
-
Book VI of the Civil and Commercial Code (CCC), which regulates testamentary wills, statutory intestate succession, and estate administrators.
-
The Condominium Act B.E. 2522 (as amended), specifically Section 19/7 and Section 19/8, which dictate whether a foreign heir may legally inherit and register a freehold unit.
-
The Inheritance Tax Act B.E. 2558 (2015), which establishes statutory tax brackets and asset valuation thresholds for inherited estates.
This article examines cross-border inheritance protocols: drafting enforceable dual-jurisdiction wills, navigating Thai probate proceedings, managing the 49% foreign quota limits on inherited condominiums, handling non-inheritable leases, and complying with statutory inheritance tax obligations.
1. Choice of Law: Conflict of Laws Act B.E. 2481
A common misconception among expatriates is that an overseas will executed in their home country (such as the UK, the US, or Australia) is sufficient to distribute their Thai assets upon death.
Under the Conflict of Laws Act B.E. 2481 (1938), Thai civil courts apply the traditional doctrine of lex rei sitae (the law of the place where the property is situated):
┌────────────────────────────────────────────────────────┐
│ CONFLICT OF LAWS ACT B.E. 2481: SECTION 37 │
│ │
│ "Succession as divided between movable and │
│ immovable property is governed: │
│ • Movable property: by the law of the domicile of │
│ the deceased at the time of their death. │
│ • Immovable property: by the law of the place where │
│ the property is situated (Lex Rei Sitae)." │
└────────────────────────────────────────────────────────┘
Because land, condominium units, and registered property rights are classified as immovable property under Section 139 of the CCC, the succession, transfer, and testamentary disposition of Thai real estate are governed exclusively by the laws of Thailand.
While a foreign will can be recognized by a Thai court under Section 39 of the Conflict of Laws Act, it creates substantial administrative friction:
-
The original foreign will, foreign death certificate, and grant of probate must be translated into Thai by a certified translator.
-
The documents must be authenticated and notarized by the foreign ministry of the issuing state and legalized by the Royal Thai Embassy or Consulate in that country.
-
A Thai probate lawyer must petition the Thai Court of Justice, presenting expert testimony or diplomatic certifications proving that the foreign will complied with the formal laws of the issuing jurisdiction.
This legalization process frequently delays estate administration by 9 to 18 months, during which common maintenance fees, property taxes, and property management issues accrue.
2. Drafting an Enforceable Thai Will: Statutory Formalities
To avoid probate delays and authentication costs, the standard legal practice is to execute a separate Thai Last Will and Testament restricted strictly to the testator’s assets situated within the Kingdom of Thailand.
DUAL-JURISDICTION WILL ARCHITECTURE
│
┌───────────────────────────────┴───────────────────────────────┐
│ │
▼ ▼
[Foreign Primary Will] [Thai Supplementary Will]
• Governs worldwide assets outside • Limited exclusively to assets located
Thailand (home country accounts, within the Kingdom of Thailand (condos,
shares, domestic real estate). Thai bank accounts, leaseholds, vehicles).
• Explicitly carves out Thai assets. • Must contain a "Non-Revocation Clause"
protecting the foreign will.
Statutory Will Formats Under the Civil and Commercial Code
Book VI, Title II of the CCC specifies the formal legal structures for executing a valid will:
┌────────────────────────────────────────────────────────────────────────┐
│ CCC STATUTORY WILL STRUCTURES │
├───────────────────────┬────────────────────────────────────────────────┤
│ Form of Will │ Statutory Requirements under the CCC │
├───────────────────────┼────────────────────────────────────────────────┤
│ Written Will │ • Governed by Section 1656 CCC. │
│ (Standard Format) │ • Must be in writing, dated at the time of │
│ │ making, and signed by the testator. │
│ │ • Must be signed before at least TWO witnesses │
│ │ present at the same time, who certify the │
│ │ testator's signature on the document. │
├───────────────────────┼────────────────────────────────────────────────┤

│ │ • Entire text must be handwritten by the │
│ │ testator personally, dated, and signed. │
│ │ • No witnesses required, but subject to high │
│ │ evidentiary scrutiny in Thai probate court. │

│ (Amphoe Registration) │ • Declared in person before the Chief District │
│ │ Officer (Nai Amphoe) at a local civil office.│
│ │ • Inscribed into the official district ledger; │
│ │ carries the highest evidentiary standing. │
└───────────────────────┴────────────────────────────────────────────────┘
The Critical “Non-Revocation” Clause
A common drafting failure occurs when a lawyer drafting a new Thai will includes boilerplate language stating: “I hereby revoke all prior wills, codicils, and testamentary dispositions made by me.”
If an expatriate signs such a document in Bangkok, that single revocation sentence can revoke their primary will back home, causing their primary overseas estate to fall into statutory intestacy.
A Thai will must contain an explicit jurisdictional limitation clause:
“This Will shall govern, apply to, and dispose solely and exclusively of my estate, real property, condominium units, leasehold interests, vehicles, and bank accounts situated within the Kingdom of Thailand. This document shall not revoke, alter, or affect any separate testamentary instruments executed by me concerning assets situated outside of Thailand.”
3. Statutory Intestacy: Succession Without a Will
If a foreign national dies without executing a valid will in Thailand or abroad, their Thai estate is distributed according to the rules of statutory intestacy set out in Book VI, Sections 1629 and 1635 of the Civil and Commercial Code.
STATUTORY CLASSES OF HEIRS

┌──────────────────────────────┴──────────────────────────────┐
│ │
▼ ▼
[Class 1: Descendants] [Surviving Spouse]
• Biological and legally adopted children. • Receives a statutory share equal

│
┌─────────────────────────────────────────────────────────────┘
│ (If no Class 1 descendants exist, succession moves down)
▼
[Class 2: Parents]
• If parents and spouse survive: 50% to parents, 50% to spouse.
│

• If no parents or descendants survive: 50% to siblings, 50% to spouse.
│
▼
[Class 4: Half-Blood Brothers and Sisters]
│
▼
[Class 5: Grandparents] ──► [Class 6: Uncles and Aunts]
Under Section 1630 of the CCC, heirs of a higher class exclude heirs of a lower class from succession, with the exception that Class 1 (children) and Class 2 (parents) inherit alongside one another if both survive.
The surviving legally registered spouse is treated as a statutory heir with rights varying depending on which class of heirs they inherit alongside (e.g., sharing equally with children, or receiving 50% of the estate if inheriting alongside surviving parents or siblings).
4. Inheriting a Foreign Freehold Condominium: Section 19/7 Quota Rules
Inheriting a foreign freehold condominium unit (Or Chor 2) is governed by specialized statutory rules. While a foreign heir can inherit the economic value of the property, they cannot automatically register their name on the title deed unless they meet the foreign quota criteria.

Statutory Mechanics Under Section 19/7 and Section 19/8
Under Section 19/7 of the Condominium Act B.E. 2522 (as amended by No. 4 B.E. 2551):
-
If an alien acquires a condominium unit by inheritance (either as a statutory heir or under a will), the heir must apply for registration of ownership at the Land Office within 60 days of the probate order.
-
The heir must provide evidence showing that they independently qualify under Section 19(1) through 19(5) (e.g., holding permanent residency or an approved BOI qualification).
-
Most importantly, the transfer cannot cause the foreign ownership ratio of that building to exceed the statutory 49% limit established by Section 19 bis.
The Compulsory One-Year Disposal Rule
If the foreign heir cannot qualify under Section 19, or if the building’s 49% foreign quota is already full, Section 19/7 (paragraph 2) mandates:
“The alien who does not qualify… shall dispose of the space in such unit within a period of not exceeding one (1) year from the date of obtaining the ownership of such unit.”
If the foreign heir fails to sell and transfer the unit to a qualifying Thai buyer or corporate entity within that 365-day statutory window, Section 19/8 authorizes the Director-General of the Department of Lands to step in, seize the title deed, and sell the condominium unit at public auction. The net proceeds from the auction, minus statutory Land Office taxes, administrative fees, and auction costs, are remitted to the heir.
5. The Fate of Leases, Usufructs, and Superficies Upon Death
When planning an estate involving landed residential villas, the choice of underlying property instrument dictates whether the asset survives the testator’s death.

└───────────────────────┴────────────────────────────────────────────────┘
The Leasehold Succession Vulnerability
Under classical Thai jurisprudence governing the Hire of Property (Sections 537–571 CCC), a lease is treated as a personal right tied to the individual tenant.
The Supreme Court of Thailand has held that unless the registered lease contract contains an express succession clause binding the landlord’s heirs and providing that the leasehold interest survives the death of the tenant, the lease terminates upon the death of the lessee.
To preserve the asset for heirs, the lease must include:
-
An explicit contractual clause stating that the leasehold interest transfers to the lessee’s heirs, executors, and assigns.
-
A clause requiring the landlord to execute an amended title endorsement registering the heir’s name at the Land Department upon notice of the lessee’s death.
6. The Thai Probate Process: Court-Appointed Estate Administration
Regardless of whether a foreign national dies with a Thai will or intestate, the Land Department and commercial banks will not transfer property or release bank balances without a formal Court Order appointing an Estate Administrator (Phu Chatkan Moradok).

Step-by-Step Probate Procedure:
-
Jurisdiction: A petition is filed with the Provincial Civil Court in the provincial jurisdiction where the deceased held their domicile or where the real estate assets are physically located (e.g., the Southern Bangkok Civil Court, Phuket Provincial Court, or Pattaya Provincial Court).
-
Documentary Evidence: The petitioner must provide:
-
Original death certificate (with consular legalizations and certified Thai translations if death occurred overseas).
-
Original Thai Last Will and Testament.
-
Certified copies of the deceased’s passport, House Registration Book (Tabien Baan), and marriage certificates.
-
Original apartment title deeds (Or Chor 2) or land deeds (Chanote).
-
Written consents from all statutory intestate heirs agreeing to the appointment of the nominated Estate Administrator.
-
-
Public Notice Period: Upon receiving the petition, the court posts an announcement at the courthouse and in local media for 15 to 30 days to notify creditors or unlisted heirs who may wish to contest the petition.
-
The Probate Hearing: The petitioner and their legal counsel appear before the civil judge. The petitioner provides sworn testimony confirming the authenticity of the will, the passing of the testator, and their fitness to act as administrator under Sections 1718–1722 of the CCC (confirming they are of legal age, solvent, and not of unsound mind).
-
Issuance of the Order and Certificate of Finality: The court issues its judgment appointing the Estate Administrator. After a statutory 30-day appeal window expires without challenge, the court clerk issues an official Certificate of Finality (Nang Sue Rap Rong Khadi Thung Thi Sut).
-
Execution at the Land Office: Equipped with the Court Order and Certificate of Finality, the Estate Administrator appears at the District Land Office. The Land Registrar endorses the title deed, officially transferring the property to the Estate Administrator, who then executes the conveyance to the designated beneficiaries under the terms of the will.
7. The Inheritance Tax Act B.E. 2558 (2015)
Prior to 2016, Thailand had no statutory inheritance tax. The Inheritance Tax Act B.E. 2558 (2015) introduced a tax framework on inherited estates, effective February 1, 2016.

└───────────────────────┴────────────────────────────────────────────────┘
Scope of Taxable Assets
Under Section 14 of the Act, taxable inherited assets include:
-
Immovable property (condominium units, land, registered long-term property rights).
-
Bank deposits held in financial institutions situated in Thailand.
-
Registered securities, corporate shares, and debentures.
-
Registered motor vehicles.
Valuation and Payment Timeline
For real property, the asset valuation is based on the Government Assessed Appraised Value fixed by the Treasury Department at the time of inheritance, rather than speculative open-market appraisals.
If the net value of inherited property exceeds the 100 million Baht threshold per beneficiary, the Estate Administrator or beneficiary must file an inheritance tax return (Form P.P. 01) with the Revenue Department within one hundred and fifty (150) days from the date of receiving the asset.
8. Summary
Structuring real estate assets in Thailand requires proactive estate planning to avoid probate complications:
-
Maintain Dual Wills: Draft an independent Thai Last Will and Testament restricted strictly to assets situated in the Kingdom, containing a clear non-revocation clause protecting your home-country wills.
-
Review Leasehold Successions: Ensure long-term leases contain explicit contractual succession covenants that survive the tenant’s death, or use statutorily inheritable instruments like a Right of Superficies.
-
Plan for Foreign Condominium Quotas: Inform beneficiaries that if an inherited condominium unit cannot be registered under the building’s 49% foreign quota, Section 19/7 mandates that the property must be sold within one year, or it will be seized and liquidated at public auction by the Department of Lands.
-
Prepare for Court-Ordered Probate: Heirs should understand that cross-border asset transfers require petitioning the local Thai Civil Court for an Estate Administrator order before the Land Department or commercial banks will release or re-register titles.
