Thai Will and Succession

In the Kingdom of Thailand, understanding wills and succession laws is crucial for both Thai citizens and expatriates residing in the country. Proper estate planning ensures that your assets are distributed according to your wishes after your passing. This comprehensive guide will delve into the key aspects of Thai wills and succession, shedding light on the legal framework, inheritance rules, and essential considerations.

Legal Framework

Thai succession laws are primarily governed by the Civil and Commercial Code (CCC) and the Thai Inheritance Tax Act. The CCC provides guidelines for wills and inheritance, while the Inheritance Tax Act regulates the taxation of inheritances. Understanding these laws is vital for anyone interested in creating a will or navigating the inheritance process in Thailand.

Types of Wills

In Thailand, there are two main types of wills: formal and informal. A formal will must be made in writing and signed by the testator (the person making the will) and two witnesses present simultaneously. It is advisable to seek legal assistance when creating a formal will to ensure its validity.

Informal wills, also known as holographic wills, are handwritten and signed by the testator without the presence of witnesses. However, these types of wills can be subject to greater scrutiny during the probate process, making them less secure than formal wills.

Inheritance Rules

Intestate Succession: When an individual passes away without a valid will (intestate), Thai law prescribes a specific order of inheritance. This order typically prioritizes the deceased person’s spouse, children, parents, and other close relatives. The distribution of assets is determined by the CCC and may not align with the testator’s preferences.

Forced Heirship: Under Thai law, certain family members are considered forced heirs and are entitled to a share of the deceased’s estate, regardless of the contents of the will. Forced heirs typically include the spouse and children. This legal provision ensures their financial security.

Disinheritance: While Thai law allows for disinheritance, it is subject to specific conditions and must be done explicitly in a formal will. Disinheritance may apply to forced heirs, but the testator must provide valid reasons for their exclusion.

Foreign Ownership and Succession

Expatriates and foreigners residing in Thailand should be aware of how the country’s laws affect their assets and estate planning. Foreigners can own property in Thailand, but it is crucial to understand how these assets will be treated in the event of death.

Non-Immigrant Visa Holders: Foreigners in Thailand on non-immigrant visas may own property and are subject to Thai inheritance laws. Proper estate planning, including the creation of a valid will, is essential to ensure the smooth transfer of assets.

Immigrant Visa Holders: Immigrant visa holders may also own property, but they are encouraged to consult with legal experts to navigate the complex process of Thai inheritance. Ensuring the proper documentation and understanding the local laws is crucial.

Inheritance Tax

Thailand has specific laws regarding inheritance tax. As of my last knowledge update in September 2021, the tax rate is progressive, based on the value of the inheritance. The rates vary depending on the relationship between the deceased and the heir. However, the specifics of these tax rates may change over time, so it is advisable to consult with a legal or tax professional for the most up-to-date information.


Understanding Thai will and succession laws is essential for anyone residing in Thailand or owning assets within the country. Whether you are a Thai citizen or a foreigner, proper estate planning can help ensure that your assets are distributed according to your wishes and in compliance with local laws. Seek legal guidance to create a formal will that addresses your unique circumstances and consult with experts who can provide up-to-date information on inheritance tax and other related matters. By doing so, you can secure your legacy and provide for your loved ones in the most efficient manner possible.
