Updated August 2026, with our real, published fees and the current government charges.
A bilingual Last Will and Testament costs 3,900 THB with our firm, a fixed fee, drafted by licensed Thai lawyers in 3 to 5 business days. A living will (advance healthcare directive) costs 1,900 THB. Here is everything that affects the price of estate planning in Thailand.
What the will needs to do, and therefore what it costs, follows from our guide to Thai inheritance law.

What the Government Charges If You Do It Yourself
You do not have to use a law firm. You can make a public will at any amphur or Bangkok khet office, and the state fee is small. The Ministerial Regulation on the Making of Wills B.E. 2569 came into force on 24 March 2026 and replaced the 1960 regulation that had governed this for 66 years. These are the official charges:
| Official charge | Fee (THB) | Before 24 March 2026 |
|---|---|---|
| Public will made at a district office | 250 | 50 |
| Certified copy of the will | 50 | 10 |
You can now register at any office, not only the one holding your house registration. Bring two witnesses, who must be present with you and sign in front of the officer, and identification: a Thai ID card, a passport, or another official photo ID showing an identity number. The officer must be satisfied that you understand what you are doing, and must refuse a will that shows signs of coercion. You keep the original and the office keeps a certified duplicate.
So the honest comparison is 250 baht against our 3,900. The difference is drafting. The district office records what you tell it. It does not warn you that a foreign heir cannot simply keep land without permission under the Land Code, that a beneficiary who signs as a witness loses their own gift under Section 1653, or that a later will made in your home country can revoke your Thai one by accident. Those mistakes surface after you die, when nobody can fix them.
Why a Thai Will Is Worth 3,900 THB
If you own anything in Thailand, a condo, a bank account, a car, a usufruct, dying without a Thai will means your heirs face a slower, more expensive probate process in a language they may not read. A bilingual Thai will names your heirs and an executor clearly under Thai law, which is what makes the court process faster and cheaper for the people you leave behind. For couples, we prepare mirror wills. Contact us for the package price.

Frequently Asked Questions
Is my foreign will valid in Thailand? A foreign will may be recognized, but using it for Thai assets typically means certified translations and a longer court process. A separate Thai will covering your Thai assets is usually faster and cheaper for your heirs.
What documents do I need? Your passport, a list of your Thai assets, and the full names and details of your heirs and executor. We handle the rest.
Does the will need witnesses? Yes. Section 1656 requires the will to be in writing, dated, and signed by you in front of at least two witnesses present at the same time, who sign to certify your signature there and then. Read the full guide to making a will in Thailand.
