Estate Planning in Thailand: Understanding Ownership Before Succession

Estate planning is often associated with making a will. While a will is an important estate planning tool, it is only one part of the process. For foreigners with assets in Thailand, effective estate planning usually begins much earlier: understanding the legal nature of the assets themselves.

The legal rules governing condominiums, leases, usufructs, superficies, company shares and marital property may determine what can be inherited, by whom and under what conditions. In many cases, the structure of ownership has a greater practical impact than the wording of a will. Estate planning in Thailand often begins with property law rather than inheritance law. This article discusses common estate planning considerations for foreigners with assets in Thailand. It does not replace legal advice, but highlights practical issues that are often overlooked.

Estate Planning Starts with Ownership

Before considering a will, identify exactly what you own in Thailand and under which legal title. Different assets are governed by different laws and may require different planning.

• Foreign freehold condominium units
• Leasehold interests
• Registered usufructs
• Rights of superficies
• Bank accounts
• Motor vehicles
• Company shares
• Personal property

Foreign-Owned Condominiums

Foreign freehold condominiums are among the most common assets owned by foreigners in Thailand. However, inheritance of a condominium is not always as straightforward as many assume. A foreign beneficiary must generally qualify under the provisions of the Condominium Act applicable to foreign ownership. This is a point frequently overlooked in practice.

It is also important to distinguish between a condominium with official condominium registration under the Condominium Act and developments marketed as "condominiums" that do not have registered condominium status. Different ownership structures may apply, including leasehold arrangements or other contractual rights.

Understanding exactly what type of property is owned is therefore an essential part of estate planning.

Inheritance of Land by Foreigners

Ownership of land requires separate consideration under the Land Code Act. Although a foreigner may inherit land as a statutory heir under Thai succession law, this does not necessarily mean that the foreign heir may retain ownership of the land.

Section 93 of the Land Code Act provides that a foreigner who acquires land by inheritance as a statutory heir may obtain ownership with the permission of the Minister of Interior, subject to the limitations set out in Section 87. In practice, however, foreign ownership under this provision depends on the existence of a treaty permitting foreign land ownership under the Land Code. As Thailand currently has no such treaty in force, Section 93 has little practical application for most foreign heirs.

Consequently, where a foreigner inherits land in Thailand, the land will generally have to be disposed of within the period prescribed by the Director-General under Section 94 of the Land Code, which must be not less than 180 days and not more than one year. If the land is not disposed of within that period, the Director-General has the authority to arrange for its sale, with the net proceeds being paid to the heir.

Long-Term Leases

A lease does not automatically pass to heirs. Whether succession is possible depends largely on the terms of the lease agreement. A properly drafted succession clause may significantly improve enforceability, whereas the absence of such a provision may create uncertainty.

Where registration is required, the lease should also be properly registered at the Land Office and recorded on the title deed. Where appropriate, registering multiple lessees from the outset may also deserve consideration.

Usufructs

Unlike ownership, a registered usufruct is generally a personal right. As a general rule, it terminates upon the death of the usufructuary and cannot be inherited.

Where appropriate, some owners consider registering multiple usufructuaries so that the right continues for the surviving usufructuary after one beneficiary dies. The suitability of such an arrangement depends on the circumstances.

Right of Superficies

Unlike a usufruct, a right of superficies may provide important estate planning advantages for foreigners who own or intend to build a house on land owned by another person. A registered right of superficies creates a separate real right that allows ownership of buildings or structures independently from ownership of the land. Unlike a usufruct, which is generally a personal right terminating upon the death of the usufructuary, a right of superficies may generally be transferred by succession, unless otherwise limited by the terms of the agreement or applicable law.

Where succession planning is an important consideration, a right of superficies may therefore provide greater continuity for future generations than arrangements based solely on a usufruct. For foreigners investing in residential property on Thai-owned land, the choice between a lease, a usufruct and a right of superficies is often an estate planning decision as much as a property law decision.

Company Shares and Business Interests

Estate planning involving Thai companies is often considerably more complex than planning for real estate or bank accounts.

Ownership of company shares may determine not only who inherits the shares themselves, but also who ultimately controls the company and its underlying assets after the shareholder's death. Where a company has been established with genuine Thai shareholders, succession planning should consider matters such as the transfer of shares, continuity of directors, authorised signatories and the company's Articles of Association.

Additional considerations may arise where nominee shareholding arrangements exist.

Although nominee shareholding designed to circumvent foreign ownership restrictions is prohibited under Thai law, such structures have historically been used in practice. Where they exist, succession planning may expose practical issues that were previously overlooked.

For example, Thai shareholders remain the registered legal owners of their shares. Their legal position cannot simply be ignored or altered upon the death of a foreign shareholder, and succession planning cannot assume that effective control of the company will automatically continue in the same manner.

Recent measures by the Department of Business Development, including enhanced verification of shareholder information and increased scrutiny of company structures, have further emphasised the importance of reviewing existing arrangements before succession becomes an issue.

For companies holding valuable assets such as land, commercial property or operating businesses, estate planning should therefore include not only succession of shares but also the practical continuity of management and corporate control.

Bank Accounts

Thai banks often require formal succession documentation before releasing funds belonging to a deceased account holder. A power of attorney generally ends upon death and therefore cannot normally be used by family members after the account holder has died.

Joint accounts may simplify matters in some situations but do not eliminate succession issues.

Vehicles

Motor vehicles are transferred through the Department of Land Transport.

Depending on the circumstances, foreign probate documentation that has been properly legalised and translated may sometimes be accepted. In other cases, a Thai court procedure may still be required. Practical requirements can differ between authorities and individual cases.

Comparison of Common Thai Asset Structures

Do You Always Need a Thai Will?

Not necessarily. A common assumption is that every foreigner with assets in Thailand should immediately prepare a separate Thai will. The answer depends largely on the type of assets involved and the overall estate planning objectives.

For someone who owns a condominium, a bank account and perhaps a vehicle, and who intends these assets to pass to the same beneficiaries named in a foreign will, a separate Thai will may not always offer significant practical advantages.

In some situations, a foreign probate order, once properly legalised and translated, may be accepted by certain authorities without requiring a full Thai probate proceeding. Land Offices may occasionally accept such documentation in practice, whereas banks often apply stricter internal requirements.

Because administrative practice differs, this should never be regarded as guaranteed. Estate planning should therefore consider both the legal rules and the practical procedures likely to be encountered.

Where a person permanently resides in Thailand, wishes to leave Thai assets to different beneficiaries, owns more complex assets, or has business interests in Thailand, a separate Thai will may become considerably more appropriate.

Factors That May Influence Estate Planning

Whether a separate Thai will or a more comprehensive estate plan is appropriate depends on the individual circumstances rather than a single legal rule.

Factors that may be relevant include:

• whether you permanently reside in Thailand;
• the type and value of your Thai assets;
• whether you intend Thai assets to pass to different beneficiaries than under your foreign will;
• ownership of business interests or complex property structures;
• marriage to a Thai national and the application of Thai marital property law;
• whether your family members are likely to administer your estate from abroad.

Someone spending only a few months each year in Thailand with limited assets may require a different approach from someone permanently living in Thailand with substantial property or business interests. Estate planning should therefore always be based on the overall circumstances rather than assumptions that every foreigner requires the same documents.

Marriage and Marital Property

Estate planning should also take account of Thai marital property law where applicable.

For many married couples, succession is straightforward because the surviving spouse is also the principal beneficiary under the will. More complex issues may arise where children from a previous relationship, other relatives, or third parties are named as beneficiaries. Before the estate can be distributed, it may first be necessary to determine which assets actually form part of the deceased's estate.

Under the Thai Civil and Commercial Code, property is classified as either personal property (Sin Suan Tua) or marital property (Sin Somros). A will governs the distribution of the deceased's estate, but it cannot dispose of assets that legally belong to the surviving spouse. Consequently, determining ownership is often an essential step before succession can be administered.

This issue commonly arises in foreign-Thai marriages, but it may also affect foreign couples who own assets in Thailand where Thai law governs the ownership or succession of those assets. Under Sections 1471 and 1474 of the Thai Civil and Commercial Code, property acquired during marriage is generally presumed to be marital property (Sin Somros) unless it can be established that it constitutes personal property (Sin Suan Tua). Particular attention should therefore be given to inherited assets, gifts, property owned before marriage, and assets acquired during the marriage using personal funds. Where the origin of funds or ownership cannot be clearly be demonstrated, disputes may arise as to whether an asset forms part of the deceased's estate or belongs wholly or partly to the surviving spouse.

Maintaining clear financial records and documentary evidence of ownership can therefore form an important part of effective estate planning. The principles explained in our article on Thai Property Division Explained are equally relevant where a marriage ends by death, as the ownership of assets may first need to be determined before the estate can be administered.

Common Estate Planning Mistakes

• Assuming every condominium can automatically pass to any foreign beneficiary
• Overlooking foreign ownership restrictions under the Condominium Act
• Relying on lease succession without an appropriate succession clause
• Failing to register long-term leases correctly
• Misunderstanding the personal nature of usufructs
• Overlooking the succession advantages of a right of superficies
• Assuming company control will continue automatically after death
• Ignoring nominee shareholder and DBD compliance issues
• Creating conflicts between Thai and foreign wills
• Overlooking the distinction between personal and marital property

Practical Estate Planning Checklist

• What assets do I own in Thailand?
• Under which legal title do I own them?
• Can the intended beneficiary legally inherit those assets?
• Are lease, usufruct or superficies arrangements properly documented?
• Are company shares, directors and authorised signatories properly reviewed?
• Is ownership clearly evidenced?
• Does my foreign will already adequately deal with my Thai assets?
• Would a separate Thai will simplify administration?
• Does my executor know where important documents are kept?

Conclusion

For foreigners, estate planning in Thailand is rarely just about drafting a will. The legal nature of the underlying assets often determines how smoothly an estate can be administered and whether intended beneficiaries can receive those assets without unnecessary complications.

Whether assets consist of a condominium, leasehold interest, right of superficies, usufruct, company shares or other property, the legal nature of those rights should be understood before deciding whether a Thai will, a foreign will or another estate planning measure is appropriate. Understanding ownership before planning succession is therefore often the most valuable first step in developing an effective estate plan in Thailand.
