Understanding the Basics of a Thai Will: A Beginner’s Guide to Estate Planning in Thailand
Planning for the future is one of the most responsible actions you can take for your loved ones. Under Thai Inheritance Law (the Civil and Commercial Code of Thailand), a valid Last Will and Testament (พินัยกรรม) is the single most effective tool to ensure your assets in Thailand are distributed exactly according to your wishes.
Whether you are a Thai national or an expat living in Thailand owning a condo, a bank account, or a business, this guide covers the essentials of making a Thai will, why it is crucial, and how it protects your legacy.
Quick Navigation
What is a Last Will and Testament under Thai Law?
Under the Thai Civil and Commercial Code (CCC), a Thai Will is a legal document that dictates how your properties, finances, and personal belongings located within Thailand will be managed and distributed after your passing.
Dying Without a Will in Thailand: Intestate
When a person passes away without a valid will in Thailand, they die “intestate.” Under Thai law, your entire estate will be divided strictly among your statutory heirs (ทายาทโดยธรรม), which are classified into 6 legal classes of relatives and the surviving spouse. If you have no living relatives, your assets will escheat to the Thai State. A will completely bypasses this default statutory formula.
Why Having a Will in Thailand is Crucial
A well-drafted Thai will provides absolute clarity and speeds up legal procedures for your family. Its primary benefits include:
Asset Control: You designate exactly who inherits your Thai assets, such as freehold condominiums, land (for Thai nationals), bank accounts, vehicles, and company shares.
Appointing an Estate Administrator: You can pre-select a trusted individual (ผู้จัดการมรดก) to manage your estate, settle local debts, and distribute assets.
Protection for Expats and Unmarried Partners: Under Thai law, unmarried partners or stepchildren have zero automatic inheritance rights. A will is the only way to protect them.
Minimizing Family Disputes: Clear, written instructions backed by proper witnesses leave no room for ambiguity, preventing costly legal battles among relatives in Thai courts.
Key Elements of a Valid Thai Will
To be legally enforceable in Thailand, a standard written will must meet these strict statutory requirements:
Age and Mental Capacity: The testator (person making the will) must be at least 15 years old and of sound mind.
Written Form: The will must be dated and signed by the testator. It can be printed or completely handwritten (Holograph Will).
Strict Witness Execution: For a standard typed will, the testator must sign the document in the presence of at least two independent witnesses simultaneously.
No Beneficiary as Witness: Under Section 1670 of the Thai CCC, witnesses and their spouses cannot inherit anything from the will. If a beneficiary signs as a witness, their clause becomes legally void.
The Court Process: Appointing an Estate Administrator
After your passing, your heirs cannot simply walk into a Thai bank or land office with your will to claim assets.
Your will must be presented to a Thai court through a formal petition to appoint the Estate Administrator (ผู้จัดการมรดก). The complexity of this court process depends on the type of will you chose:
Private/Holograph Will: If you kept the will privately, your heirs face a higher burden of proof. They must present the court with additional evidence, such as handwriting verification, and bring the 2 witnesses to court to verify its authenticity.
Public Will (Pinaigam Fai Muang): If you registered your will officially at a local District Office (Amphur/Khet), the court grants it instant credibility. Your heirs will require minimal extra paperwork, resulting in a much faster court order.
When to Update Your Thai Will
A Thai will should evolve with your life. Estate planners recommend reviewing your will every 3 to 5 years, or immediately following major life events:
Marriage, divorce, or remarriage.
Acquiring significant new Thai assets (e.g., buying a new condo or opening a new bank account).
Changes in Thai corporate structures or shareholdings.
The passing away of a named estate administrator or beneficiary.

Frequently Asked Questions (FAQs)
1. Can a foreigner make a will in Thailand?
Yes. Foreigners who own assets in Thailand (such as condominiums, bank accounts, or leasehold rights) can and should make a Thai will. It is highly recommended to have a separate will specifically for your Thai assets to avoid cross-border probate delays.
2. Does a handwritten will need witnesses in Thailand?
Under Section 1665 of the Thai CCC, a completely handwritten will (Holograph Will) written, dated, and signed by your own hand does not strictly require witnesses to be valid. However, in practical terms, attaching 2 witnesses and copies of their IDs is highly recommended to make the verification process easy for your heirs in a Thai court.
3. Where should I store my Thai will?
You can keep a private will in a safe place, leave it with a legal professional, or register it as a Public Will at any local District Office (Amphur/Khet) where the original will is safely kept in government archives.
