Making a Will in Thailand: A Guide for Foreigners and Expats

Why Foreigners Need a Will in Thailand

Many foreigners living in Thailand own assets such as condominiums, bank accounts, vehicles, and personal property. Without a valid will, these assets will be distributed according to Thai intestate succession law, which may not align with your wishes. The process of settling an estate without a will in Thailand is notoriously slow and complex, often taking one to two years or longer, and can result in assets being frozen in bank accounts while courts determine rightful heirs.

A properly drafted Thai will ensures that your assets in Thailand are distributed according to your wishes, minimizes legal complications for your loved ones, and significantly speeds up the probate process. If you have a Thai spouse or partner who is not legally married to you, a will is especially critical — without one, they may receive nothing under intestate succession law.

Thai Inheritance Law Basics for Foreigners

Who Can Make a Will

Under the Thai Civil and Commercial Code (Section 1646), any person who is at least 15 years old and of sound mind can make a will. Nationality is not a restriction — foreigners have the same right to create a will in Thailand as Thai nationals. The will must be made voluntarily, without coercion or undue influence.

Intestate Succession (Without a Will)

If you die without a will in Thailand, your Thai assets are distributed according to Sections 1629-1631 of the Civil and Commercial Code. Statutory heirs are ranked in six classes: (1) descendants, (2) parents, (3) brothers and sisters of full blood, (4) brothers and sisters of half blood, (5) grandparents, and (6) uncles and aunts. A surviving legal spouse also inherits a share alongside the statutory heirs. Notably, an unmarried partner — no matter how long you have lived together — receives nothing under intestate succession.

What Foreigners Can and Cannot Own

Understanding Thai property ownership rules is essential for estate planning. Foreigners can legally own condominium units (up to 49% of total units in any building), bank accounts, vehicles, and personal property. Foreigners cannot own land in Thailand. If a foreigner inherits land through a will, Thai law requires the land to be sold within a reasonable period (typically one year). The proceeds from the sale can then be distributed to beneficiaries.

Types of Wills Recognized in Thailand

Thai law recognizes several types of wills (Sections 1655-1672):

• Written will (Section 1656): The most common type. It must be made in writing, state the date it was made, and be signed by the testator in the presence of at least two witnesses, who must also sign. This is the format used by our service.
• Holographic will (Section 1657): Entirely handwritten by the testator, including the date and signature. No witnesses required. While valid, this format can be more easily challenged.
• Public will (Section 1658): Made before an Amphur (district) official. The testator declares their wishes to the official, who records them, reads them back, and then the testator, the official, and two witnesses all sign.
• Secret will (Section 1660): The testator signs the will, seals it, and presents it to an Amphur official and two witnesses, declaring that it is their will. The official notes the date and signs the sealed envelope.

What to Include in Your Thai Will

A comprehensive Thai will for foreigners should include:

1. Full identification: Your complete legal name, passport number, nationality, and current address in Thailand. Include any alternative spellings of your name that may appear on property documents.
2. Revocation clause: A clear statement revoking all previous wills and codicils, especially important if you have wills in other countries covering non-Thai assets.
3. Asset inventory: A detailed description of your Thai assets — condominium unit numbers and chanote numbers, bank account numbers and bank names, vehicle registration details, and any other significant property.
4. Beneficiary designations: Full names, passport or ID numbers, relationships, and the specific share each beneficiary is to receive. Be as precise as possible to avoid disputes.
5. Executor appointment: Name a trusted person to manage the estate administration. The executor will be responsible for filing the probate petition, gathering assets, paying debts, and distributing property to beneficiaries.
6. Special instructions: Any specific wishes about funeral arrangements, charitable donations, or conditions on inheritances.

The Probate Process in Thailand

After the testator dies, the will must go through probate — a legal process where the court confirms the validity of the will and appoints an estate administrator. The executor or a beneficiary files a petition with the Civil Court in the jurisdiction where the deceased last resided or where their major assets are located.

The court will examine the will for proper execution, confirm the identity of beneficiaries, and issue a court order appointing the estate administrator. With a properly drafted Thai will, this process typically takes three to six months. The administrator then has authority to access bank accounts, transfer property, and distribute assets according to the will.

Without a will, the process is considerably more complex. All potential statutory heirs must be identified and notified, which can involve tracking down relatives in multiple countries. Disputes among heirs are common and can extend the process to one to two years or more.

Common Mistakes to Avoid

• Not making a Thai will at all: Many expats assume their home country will covers Thai assets. While technically possible, enforcing a foreign will in Thailand is extremely difficult and time-consuming.
• Conflicting wills: If you have wills in multiple countries, ensure your Thai will explicitly covers only Thai assets and does not inadvertently revoke your other wills.
• Naming minor children as beneficiaries without a guardian: If beneficiaries are minors, consider naming a guardian or trustee to manage their inheritance until they reach legal age.
• Forgetting to update: Life changes — marriage, divorce, birth of children, acquisition of new assets — should all trigger a review and possible update of your will.
• Inadequate witness requirements: Ensure your witnesses are present during signing and that they are not beneficiaries named in the will (Section 1653).

Conclusion

Making a will in Thailand is one of the most important steps any foreigner with Thai assets can take to protect their legacy and loved ones. Thai law provides clear and accessible mechanisms for foreigners to create valid wills, and the benefits of having one far outweigh the relatively modest effort involved. Do not leave the distribution of your assets to chance — create a Thai will and give yourself and your family peace of mind.
