Thai Will for Foreigners: Planning for Assets in Thailand

Many foreigners own valuable assets in Thailand, including condominiums, bank accounts, vehicles, investments, and business interests. Having a properly drafted Thai will can help ensure that these assets are distributed according to your wishes and may simplify the administration of your estate for your loved ones.

For an overview of the entire probate and inheritance process, see our main Probate & Inheritance guide.

Can a Foreigner Make a Will in Thailand?

Yes. Thai law allows foreigners to prepare and execute a valid will covering assets located in Thailand. A properly drafted Thai will enables the testator to specify who should inherit their Thai assets and appoint an executor to administer the estate.

A Thai will generally applies only to assets located in Thailand unless specifically intended otherwise. Many international estate planning strategies therefore include both a will in the individual's home country and a separate Thai will that deals exclusively with Thai assets.

Why Foreigners With Thai Assets May Consider a Thai Will

Many foreigners already have a will prepared in their home country. However, relying solely on a foreign will may create practical difficulties when dealing with Thai assets.

A separate Thai will can:

• Simplify probate proceedings in Thailand
• Reduce administrative delays
• Avoid conflicting interpretations
• Clearly identify Thai assets
• Appoint a local executor familiar with Thai legal procedures
• Reduce translation and legalization requirements

Assets That May Be Addressed

A Thai will may cover various assets situated in Thailand, including:

• Condominiums
• Bank accounts
• Motor vehicles
• Shares in Thai companies
• Investment accounts
• Personal belongings
• Leasehold rights
• Intellectual property rights located in Thailand

A lawyer can advise whether particular assets should be included based on your personal circumstances.

Formal Requirements Under Thai Law

Thai law recognises several types of wills, each with specific formal requirements. A will that does not comply with these requirements may be invalid. Common types include:

• Holograph will — entirely handwritten and signed by the testator
• Formal will — made in writing, dated, and witnessed by at least two witnesses
• Public will — made before a public official with formal recording
• Secret will — sealed and presented to the court or official with specific formalities

Professional legal advice can help ensure that the will complies with the applicable formal requirements.

Choosing an Estate Administrator

An executor is responsible for administering the estate after death. Their responsibilities may include filing applications with the Thai court, collecting estate assets, paying outstanding debts, distributing assets according to the will, and coordinating with banks and government authorities.

Choosing a reliable executor can significantly reduce complications for surviving family members. For a detailed guide to the estate administrator's role, see our estate administrator guide.

Beneficiaries

Foreigners generally have the freedom to choose beneficiaries through a valid Thai will, subject to applicable legal restrictions. Beneficiaries may include a spouse, children, parents, other relatives, friends, or charitable organizations.

However, inheritance of certain assets — particularly land — may be subject to separate legal restrictions affecting foreign ownership. Legal advice should be obtained where these issues arise.

Thai and Overseas Assets

A Thai will typically deals with assets located in Thailand. Assets located in other countries may be governed by a separate will prepared in the relevant jurisdiction.

It is important that multiple wills are drafted carefully so they complement rather than unintentionally revoke one another.

Relationship Between a Thai Will and a Foreign Will

Many foreign nationals maintain separate wills for assets in different countries. This approach can work well, provided the wills are drafted carefully to avoid conflicts.

For example, a Thai will might deal exclusively with Thai assets, while a will in the home country deals with assets located there. Legal advice is important to ensure that the documents do not unintentionally revoke or conflict with one another.

Avoiding Conflicting Wills

Conflicting wills can create significant legal problems. Common issues include:

• One will inadvertently revoking another
• Inconsistent provisions regarding the same assets
• Uncertainty about which will governs which assets
• Delays in probate while the court determines validity

Professional drafting helps minimize these risks.

Language and Translation

A Thai will is typically prepared in Thai. If the testator does not read Thai, a certified translation should be provided so the testator understands the contents before signing. Accurate translation is important to avoid ambiguities or disputes.

Updating or Revoking a Will

A will should be reviewed after major life events such as marriage, divorce, the birth of a child, or the acquisition of significant new assets. A will may be updated by preparing a new will or a codicil, or revoked in accordance with Thai law.

What Happens After Death?

After death, the will is typically submitted to the Thai court for probate. The court will examine the will to determine its validity and appoint an estate administrator to administer the estate in accordance with the will and applicable law.

Common Estate Planning Mistakes

Some of the most common estate planning mistakes include:

• Assuming a foreign will automatically covers Thai assets without complication
• Not updating a will after marriage or divorce
• Failing to identify all Thai assets
• Appointing an unsuitable executor
• Using unclear or ambiguous language
• Signing an invalid will that does not comply with Thai legal requirements

Professional drafting helps minimize these risks.
