Probate & Inheritance in Thailand for Foreigners

Inheritance matters involving Thailand may arise in a range of situations — when a foreign national dies owning assets in Thailand, when a Thai national dies leaving foreign heirs, or when an overseas beneficiary inherits Thai assets. This guide explains Thai probate and inheritance procedures for international clients.

These matters often involve a Thai or foreign will, Thai bank accounts, condominium units, investments, or other assets forming part of the estate. In many cases, an estate administrator needs to be appointed by the court before assets can be accessed or transferred. Where heirs disagree about the estate, additional proceedings may be required.

This page provides an overview of probate and inheritance in Thailand for foreign nationals, overseas heirs, executors, and international families. It links to detailed guides on specific topics within the Probate & Inheritance cluster.

Understanding Probate and Inheritance in Thailand

Inheritance in Thailand is primarily governed by the Civil and Commercial Code. When a person dies, their estate does not automatically pass to their heirs. Instead, the legal rights of heirs must be established, and in many cases a court-appointed estate administrator must manage and distribute the estate.

For foreign nationals and overseas heirs, the process may involve additional steps, including translation and legalization of foreign documents, coordination between jurisdictions, and compliance with Thai rules on foreign ownership of certain assets.

When Is Probate Required in Thailand?

Probate proceedings are commonly required when the deceased owned assets in Thailand that cannot be transferred without a court order. These may include:

• Bank accounts held in Thai financial institutions
• Condominium units registered under Thai law
• Land or property interests where legally applicable
• Motor vehicles
• Shares in Thai companies
• Investments and securities
• Other assets requiring formal transfer

Many banks, the Land Department, and other government authorities require a court order appointing an estate administrator before allowing transactions involving the deceased's assets.

What Happens When Someone Dies With Assets in Thailand?

When a person dies leaving assets in Thailand, the following steps are commonly involved:

• Identifying the deceased's assets in Thailand
• Determining whether a valid will exists
• Establishing the lawful heirs under Thai law or the will
• Applying to the court for appointment of an estate administrator
• Administering the estate — collecting assets, paying debts, and distributing to heirs
• Transferring or disposing of inherited assets in accordance with Thai law

The specific steps depend on the circumstances of the estate, the type of assets involved, and whether the heirs are located in Thailand or overseas.

What If There Is a Will?

If the deceased left a valid will, the estate is generally distributed according to the wishes expressed in the will, subject to applicable Thai law. The will may name an executor who is responsible for administering the estate.

The court will examine the will to determine its validity before appointing an estate administrator. If the will was made abroad, questions of form, translation, and authentication may arise. For a detailed discussion, see our guide on foreign wills and Thai assets and our guide on Thai wills for foreigners.

What If There Is No Will?

If the deceased did not leave a valid will, the estate is distributed according to the statutory heir classes defined in the Civil and Commercial Code. The statutory heirs are determined in order: descendants, parents, siblings, grandparents, and uncles and aunts. A surviving spouse also has inheritance rights under Thai law.

Where there is no will, the court must appoint an estate administrator to manage and distribute the estate. For more information, see our guide on estate administrators in Thailand.

Appointment of an Estate Administrator

An estate administrator is a person appointed by the Thai court to administer the estate of a deceased individual. The administrator has authority to collect assets, contact banks, pay debts, and distribute the estate to the lawful heirs.

A petition for appointment may be filed by a lawful heir, a beneficiary named in a will, or another person with a legal interest in the estate. The court considers the evidence and the suitability of the applicant before issuing an appointment order.

For a detailed guide to the appointment process, required documents, and the administrator's role, see our estate administrator guide.

Foreign Heirs and Beneficiaries

Foreign nationals may be heirs under Thai law, whether through a will or through statutory succession. However, the ability to inherit, own, register, or retain specific assets depends on the type of asset and applicable Thai law.

Foreign heirs may face additional practical considerations, including document translation and legalization, the need to appoint a lawyer in Thailand, and cross-border transfer of inherited funds. For a comprehensive guide, see our page on foreign heirs and inheritance in Thailand.

Thai Assets Commonly Involved in an Estate

Estate assets in Thailand may include:

• Thai bank accounts
• Condominium units
• Land or property interests where legally applicable
• Vehicles
• Shares in Thai companies
• Investments and securities
• Personal property
• Contractual rights and receivables

Each type of asset may be subject to different transfer procedures and legal requirements. For example, the rules governing inheritance of a condominium differ from those governing land. For a detailed discussion of what happens to a bank account after death, see our guide on Thai bank accounts after death.

Thai Wills and Foreign Wills

A Thai will is a legal document that sets out how assets located in Thailand should be distributed after death. Many foreign nationals who own assets in Thailand choose to prepare a separate Thai will to simplify probate and reduce administrative complications.

A will made abroad may be relevant to Thai assets, but its form, validity, and language may affect how it is treated in Thai proceedings. For detailed guidance, see our pages on Thai wills for foreigners and foreign wills involving Thai assets.

Probate Court Proceedings

Probate proceedings in Thailand typically involve:

• Preparing and filing a petition with the competent Thai court
• Submitting supporting evidence, including the death certificate, will, and heirship documents
• Attending a court hearing where the evidence is examined
• Receiving a court order appointing the estate administrator
• Administering the estate in accordance with the court order and applicable law

The duration of probate depends on the complexity of the estate, the number of heirs, and whether disputes arise. Uncontested cases may take several months, while contested cases can take significantly longer.

Can an Overseas Heir Handle the Matter Without Remaining in Thailand?

In some cases, an overseas heir may be able to participate in probate proceedings without remaining in Thailand for the entire process. A lawyer in Thailand may be able to act on the heir's behalf through a properly executed power of attorney.

However, participation requirements depend on the procedure, the documents, court directions, and the circumstances of the case. Certain steps — such as signing documents or attending court hearings — may require personal appearance. Remote participation cannot be guaranteed and should be assessed on a case-by-case basis.

Inheritance Disputes

Disagreements between heirs, challenges to a will, or concerns about the conduct of an estate administrator may lead to inheritance disputes. Such disputes may be resolved through negotiation or, where necessary, through court proceedings.

For guidance on common types of estate disputes and how they may be resolved, see our page on inheritance disputes in Thailand.

Documents Commonly Required

The documents required depend on the circumstances of the estate but commonly include:

• Death certificate
• Identification documents of the deceased and the applicant
• The deceased's will, if any
• Family relationship documents — marriage certificate, birth certificates
• Evidence of the deceased's assets in Thailand
• House registration where applicable
• Power of attorney where heirs are overseas
• Certified Thai translations of foreign documents
• Legalized or authenticated foreign documents where required

Foreign-issued documents generally require legalization or authentication before they can be used in Thai court proceedings.
