If you are an expat living in Thailand, you may be asking whether you can use a template or write your own will.
At first glance, this may seem like a simple way to save time and money. In practice, it is rarely a reliable approach for expats.
A Thai will is not just a statement of your wishes. It is a legal document that needs to work under Thai law and, in practice, should be prepared in Thai. Otherwise, it will usually need to be translated before it can be used in probate. It also needs to be clear enough for others to rely on when the time comes.
This guide explains whether you can write your own will in Thailand, where templates fall short and why, for most expats, a more structured approach is usually the better option.
Can You Write Your Own Will in Thailand?
In principle, yes.
Thai law does not require you to use a lawyer to make a will. A foreigner can prepare their own will, provided it complies with Thai legal requirements and is properly signed and witnessed.
Legal possibility, though, is not the same as practical suitability.
A will must be valid, clearly drafted and capable of being used in Thailand when the time comes. For most expats, meeting those requirements without professional input is not just difficult. It is usually unrealistic.
Why DIY Wills Are Usually a Poor Fit for Expats
For most expats, writing your own will in Thailand is not a realistic option.
The main issue is not simply legal complexity. It is language, legal precision and whether the document will work properly in practice.
A Thai will normally need to be prepared in Thai, usually with an English translation, so that you can understand what it says. Most expats do not have the level of Thai required to draft a legally effective document with the necessary precision.
Even where someone is comfortable with conversational Thai, legal drafting is different. The wording must be clear, specific and aligned with Thai legal concepts. Small differences in phrasing can change meaning or create uncertainty later.
There are also formal requirements around signing and witnessing. These must be followed carefully. A document that appears correct at first glance may still fail if those steps are not handled properly.
For most expats, the challenge is not knowing what they want to say. It is expressing those wishes in a form that works properly under Thai law, in the Thai language and in practice when the time comes.
Why a Template Is Usually Not Enough
Templates are designed to be generic.
They can provide a starting point, but they do not take into account your specific circumstances. This is where problems often arise.
A template will not usually address:
- How a Thai will interacts with an existing foreign will
- How assets are held in Thailand, including company structures or lease arrangements
- How different types of property are treated under Thai law
- How to reflect a more complex family structure clearly
- How to ensure the document works in practice for the people who will rely on it
Many of these issues overlap with the common mistakes expats make when putting wills in place in Thailand.
In many cases, a template may appear to cover the basics but still leave gaps or create ambiguity. Those issues may not be obvious when the will is written, but they can become significant later.
The Risk Is Not Just Legal, It Is Practical
A will is not written only for the person making it. It is also written for the people who will one day need to rely on it.
If the document is unclear, incomplete or difficult to apply in Thailand, the burden falls on family members and executors.
They may need to:
- Interpret unclear wording
- Deal with documents that are not aligned with Thai practice
- Navigate additional legal steps that could have been avoided
- Manage delays or complications at a difficult time
The question is not only whether a will is technically valid. It is whether your family can rely on it when the time comes.
Are There Any Situations Where DIY May Be Acceptable?
There are limited situations where a very simple approach may be workable.
This is more likely to be the case where:
- You have a small number of straightforward Thai assets
- Your wishes are simple and unlikely to change
- There is no interaction with another jurisdiction
- There is no existing foreign will to consider
Even in these situations, most expats still face the language and formal requirements described above.
In practice, genuinely suitable DIY cases are rare.
The Better Question Is Not ‘Can I Do It Myself?’
The more useful question is not whether you can write your own will.
It is whether the will works properly when it is needed.
A document that appears simple can still cause problems if it is unclear, incomplete or not suited to the wider context.
The aim is not simply to produce a will. It is to produce a will that:
- Is valid under Thai law
- Reflects your situation accurately
- Fits with any wider arrangements
- Can be relied on by your family when the time comes
Understanding Your Options
For some expats, a straightforward Thai will is enough.
For others, the situation may require a more structured approach because of overseas assets, multiple wills, family complexity or wider succession considerations.
If you are unsure which level of planning is appropriate, you can view a comparison of the different levels of succession preparation available.
