Thai inheritance law centres on a valid will and a list of statutory heirs, while inheritance tax of 5–10% applies only to estates worth over 100 million baht. Spouses are exempt, direct descendants pay 5%, and others pay 10%. Foreigners can inherit a condominium freehold but not land outright, and a separate 5% gift tax applies to large lifetime transfers of property.

Navigating inheritance laws and taxes in any country can seem both uncomfortable and complicated. Thailand is no different, but it doesn’t have to be. And getting a head start on your education may reduce stress down the road.

The Fundamentals of Inheritance Law in Thailand

Like many countries, the last will and testament is at the core of inheritance law in Thailand. When a legal will is appropriately established, the conditions must be observed.

If there is no last will and testament, the principles laid out in the 1925 Thai Civil and Commercial Code apply. Section 1629 of this document clearly defines the succession path in the event that there’s no will, beginning with direct descendants.

Spousal inheritance rules are outlined in section 1635 and are more complicated. They receive a different amount depending on which class of heirs from section 1629 are alive. At the first stage, they share the inheritance equally with the children. In the next stages, they collect larger and larger portions of the total. This applies to foreign spouses.

Property inheritance follows similar principles as long as it doesn’t conflict with the Land Code Act. In particular, this act still doesn’t allow alien registration of land ownership, so anything inherited must be sold within one year. Condominiums are subject to the Condominium Act.

Writing the Will and Testament in Thailand

Anyone can write a legally recognized will and testament in Thailand by their own hand as long as they are at least 15 years old and follow the principles outlined in chapter 2 of the Thai Civil and Commercial Code. Here are some of the different legally recognized methods of writing a will in Thailand:

  • Writing by your own hand in the presence of two witnesses. All three parties sign and date the document.
  • A “holographic will” which is written, signed, and dated only by the owner of the will. This type of will may not be recognized abroad.
  • A public will which is submitted to the District (Amphoe) office in the presence of an official and two witnesses.
  • A secret will which is sealed and submitted to the Amphoe office in the presence of an official and two witnesses.

When completing a last will and testament in Thailand, most of the usual steps must be completed. Some of these include designating an executor and listing their address, listing your assets and how they’re to be assigned, appointing guardians for minors, and setting up your preferred succession pattern.

Who Are Considered Statutory Heirs to Property Under Thai Inheritance Law?

Thai statutory heirs orgchart showing the six classes of heirs in Section 1629 succession order — direct descendants, parents, full-blood siblings, half-blood siblings, grandparents, and uncles and aunts — where a living higher class blocks all classes below under Section 1630.
The six statutory-heir classes under Section 1629; a surviving spouse always shares alongside them.

Under Thai inheritance law outlined in section 1629 of the Civil and Commercial Code, the following are considered statutory heirs to property in the absence of a will:

  1. Direct descendants (children, grandchildren, great-grandchildren)
  2. Parents
  3. Full-blood siblings
  4. Half-blood siblings
  5. Grandparents
  6. Uncles and aunts

According to section 1630 of the Civil and Commercial Code, if a person at any step along the succession line is alive and accessible, all people below are ineligible.

Whether foreign or Thai, spouses are considered statutory heirs as outlined in section 1629 with inheritance rights.

Can an Heir Be Disinherited From a Will?

Yes, an heir can be disinherited from a will if the subject of the will submits an official change to the will according to section 1608 of the Civil and Commercial Code. Any statutory heirs outside of descendants and spouses are also automatically disinherited if someone in the class above them inherits.

Conditions for the Appointment of an Estate Administrator to Heirs in Thailand

Whether or not a deceased person leaves behind a will, heirs and interested parties can apply to the courts to be appointed as an estate administrator under the probate process in Thailand as long as they meet the following conditions:

  • They are not bankrupt according to the court
  • They are of competent, sound mind
  • They are 20 years old or over

In addition, several documents may be required for the estate administrator application:

  • Death certificate
  • Marriage certificate (in the case of spouses)
  • Birth certificate of heir(s)
  • List of relatives
  • List of assets
  • Proof of residence of the decedent at time of death

The order of final judgment typically takes 3-4 months as long as no other party puts in a request.

Steps in the Probate Process in Thailand

There are 6 steps in the probate process in Thailand:

  1. Reviewing the facts around the deceased with the help of an attorney, including estate assets and the presence of a will.
  2. Having the attorney assess any legal heirs, debts and other information regarding the estate.
  3. Having the attorney file an application to initiate the probate process with the courts.
  4. Preparing a testimonial in Thai with your attorney.
  5. Beginning of the court examination with client and attorney present.
  6. Waiting for the final decree which takes 30 days.

Duties of an Estate Administrator According to Inheritance Law in Thailand

There are 3 main duties of an estate administrator according to inheritance law in Thailand:

    1. Assessing the assets of the deceased within 15 days of the death or appointment as the estate administrator.
    2. Settling the debts and taxes of the deceased.
    3. Distributing the assets according to a will or succession order which may include real estate ownership transfers.

What Is Inheritance Tax in Thailand?

Inheritance tax in Thailand is 0% for spouses, 5% for parents or descendants, and 10% for any other heir. However, this tax is only applied on total assets exceeding 100 million Thai baht.

The 2015 Inheritance Tax Act governs inheritance in Thailand and applies in different situations to Thai and non-Thai citizens. It covers many different asset classes such as cash, securities, and inherited property.

Inheritance Tax and Transfer Fees on Real Estate Transferred While Alive

Real estate transferred while alive is not subject to inheritance tax. Instead, there are three cases with different levels of land transfer fees that apply according to Thai tax and property law.

Case Fees and Taxes
Legitimate children
  • Real estate ownership transfer fee (0.5% of appraised value)
  • Stamp duty (0.5% of appraised value)
  • Income (gift) tax on value exceeding 20 million baht (5% of assessed value). This tax can be avoided if the land is divided into no more than 9 plots and transferred at a value of less than 20 million baht per year.
Non-legal children
  • Real estate ownership transfer fee (0.5% of appraised value)
  • Either stamp duty of 0.5% or 3.3% specific business tax (SBT) on appraised value. SBT applies only if the owner held the property for less than 5 years or didn’t register it as their primary residence for more than 1 year.
  • Income tax on appraised value (based on progressive rates). Expenses are 50% tax-deductible.
Relatives other than children
  • Real estate ownership transfer fee (2% of appraised value)
  • Either stamp duty of 0.5% or 3.3% SBT on appraised value
  • Income tax on appraised value (based on progressive rates)

Inheritance Tax and Transfer Fees on Real Estate Transferred After Death

Thai inheritance transfer costs after death by heir class — spouses pay a 0.5% transfer fee and no inheritance tax, full-blood descendants and parents pay 0.5% plus 5% inheritance tax over 100 million baht, and other heirs including adopted children pay 2% plus 10% inheritance tax over 100 million baht.

Frequently asked questions

Is there inheritance tax in Thailand?
Yes, but only on large estates. Under the Inheritance Tax Act of 2015, inheritance tax applies to the value of an estate above 100 million baht. Direct descendants and ascendants pay 5%, while other heirs pay 10%. Spouses are fully exempt regardless of value. Most ordinary estates fall below the threshold and pay no inheritance tax at all.
Who are the statutory heirs under Thai inheritance law?
When there is no will, Thai law distributes an estate among statutory heirs in order of priority: descendants such as children, then parents, siblings, half-siblings, grandparents, and aunts or uncles, alongside the surviving spouse who always shares in the estate. A valid will can change this distribution, but cannot fully disinherit certain protected heirs without proper grounds.
Can foreigners inherit property in Thailand?
Foreigners can inherit a condominium freehold and receive its Chanote title deed, subject to the building's 49% foreign quota. They cannot inherit land into outright ownership; inherited land must usually be sold within a set period or held through permitted structures. Inheritance tax still applies above the 100 million baht threshold, at 5% for descendants or 10% for others.
Are foreign wills valid in Thailand?
Yes, foreign wills are valid in Thailand, but they must be officially translated and reviewed by a Thai court, which can take a long time and delay the estate. Because of this, having a separate Thai will covering Thai assets, especially property, is strongly advised. A local will speeds up probate and reduces the risk of disputes over translation or interpretation.
Is there a gift tax in Thailand?
Yes. Since February 2016, Thailand has a 5% gift tax, introduced with the inheritance tax. It applies to immovable property gifted to children above 20 million baht, and to cash, shares and valuables above the same threshold, with exemptions for gifts to ancestors, descendants or spouses within limits. The gift tax prevents avoiding inheritance tax by transferring assets while alive.
