Legal Framework
Under Thai law, any person may arrange the distribution of their assets by means of a will and determine any other provisions permitted by law, which will take effect upon their death.
In the absence of a valid will, the estate will be distributed according to the statutory rules governing succession. Thai law recognizes six classes of heirs, who are entitled to inherit in the following order:
- Descendants and the surviving spouse
- Parents
- Full siblings
- Half-siblings
- Grandparents
- Uncles and aunts
Where no will exists, the administration of the estate may require a longer legal process before the courts, particularly if the court must appoint an administrator for the estate.
Other Forms of Wills
In addition to a standard will, Thai law provides for other forms of testamentary documents, including:
- An official will: prepared and registered at the district office, where its content is recorded by a public officer.
- A secret will: also registered with the district office, but submitted in a sealed envelope to the public officer.
Our firm can also assist you with the preparation of these specific forms of wills
