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?

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:
- Direct descendants (children, grandchildren, great-grandchildren)
- Parents
- Full-blood siblings
- Half-blood siblings
- Grandparents
- 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.
