Nobody wants to think about it — but if you own a condo in Rawai, have ฿500,000 sitting in a Kasikorn account, and your Thai pension fund has you as the policy holder, your heirs could spend a year and a small fortune trying to untangle your estate without a proper plan. I've seen it happen. A British retiree in Chalong passed away with no Thai will. His son flew in from the UK, spent six months in a legal loop, paid a Thai lawyer ฿80,000 in fees, and still had to sell the condo at a discount because buyers wouldn't touch it while probate was open.
The good news: Thai estate planning for expats is entirely manageable. A few hours with a reputable Phuket lawyer, a couple of thousand baht, and you can protect your assets and spare your family an enormous headache. This guide covers everything you need to know, written specifically for people who live here.
Key Facts: Thai Succession Law for Foreigners
- Thailand has no bilateral inheritance treaties with most Western countries — a foreign will alone is insufficient for Thai assets
- A separate Thai will is strongly recommended for any assets held in Thailand
- Foreigners cannot inherit freehold land; condos on foreign quota can be inherited by foreign nationals
- Thai inheritance tax applies above ฿100 million to non-lineal heirs (10%); lineal heirs pay 5% above that
- Intestacy can mean 12–18 months of court process and significant legal costs
- Thai wills must be signed in front of two witnesses; both signatures must be made on the same occasion
- A simple Thai will costs ฿5,000–฿15,000 — one of the best investments you can make
Why Your Home-Country Will Isn't Enough
Your UK, Australian, or US will is a legal document recognised in your home country. To use it in Thailand, your heirs would need to get it legalised with an apostille, translated into Thai by a certified translator, and then present it to a Thai court — a process that can take months and costs money at each step. Courts sometimes reject foreign wills for technical reasons (wrong format, missing notarisations) and the whole process starts over.
A Thai will, drafted in Thai and signed according to Thai Civil and Commercial Code requirements, bypasses all of that. Your heirs go to a Thai court with a clean Thai document. It's straightforward by comparison.
If you die without a valid Thai will (intestate), Thai law determines who inherits. The order is: spouse → children → parents → siblings → grandparents → aunts/uncles. If there are no qualifying relatives in Thailand, assets may ultimately pass to the Thai state. More practically: even if your heirs are clearly identified, the court-administered intestacy process is significantly slower and more expensive than probate under a valid will.
What Assets Do You Actually Have in Thailand?
Before planning, inventory what you own here. Most Phuket expat estates include a combination of the following:
🏠 Property
- Condo (foreign quota title — can be inherited by foreigners)
- Condo (Thai quota title — may need transfer to Thai entity)
- House on land (land cannot be inherited by foreigners)
- Lease rights (leasehold positions — check what's transferable)
🏦 Financial Accounts
- Thai bank accounts (KBank, Bangkok Bank, SCB)
- Fixed deposit accounts
- Thai provident/pension funds
- Brokerage accounts with Thai securities
🚗 Vehicles & Personal
- Registered car or motorcycle
- High-value personal items (jewellery, art, electronics)
- Business interests in Thai companies
- Shares in Thai-registered entities
📋 Insurance & Policies
- Life insurance with Thai insurers
- Health insurance policies (usually separate, check terms)
- Investment-linked insurance products
- Pension or annuity products
Thai Will Requirements
Under the Thai Civil and Commercial Code, a valid will must meet specific technical requirements. Getting these wrong can invalidate the entire document. There are five types of Thai will; the two most practical for expats are the witnessed will and the holographic will, with the witnessed will strongly preferred.
| Requirement | Witnessed Will | Holographic Will |
|---|---|---|
| Format | Typed or handwritten | Must be entirely handwritten by testator |
| Signatures | Testator + 2 witnesses, same occasion | Testator only (no witnesses needed) |
| Date | Required | Required — full date including day/month/year |
| Language | Thai strongly recommended | Thai strongly recommended |
| Witnesses can be beneficiaries? | No — disqualifies the bequest | N/A |
| Notarisation | Not required but advisable | Not required |
| Practicality for expats | Best option | Acceptable for simple estates |
Practical note on language: Your will can be bilingual (English and Thai on the same page), but the Thai version governs Thai legal proceedings. Always have a certified Thai translator produce the Thai text — don't rely on Google Translate for a legal document.
Property Inheritance: The Land Question
This is the part that surprises most expats. Thai land law restricts foreign ownership of land — and this restriction extends to inheritance. Here's how it breaks down:
| Asset Type | Foreign Beneficiary | What Happens |
|---|---|---|
| Condo — Foreign Quota | Can inherit | Title transfers normally; foreign quota maintained |
| Condo — Thai Quota | Cannot hold in own name | Must sell, transfer to Thai person, or restructure |
| Land (Chanote, Nor Sor) | Cannot inherit land | Must sell within reasonable period (typically 1 year) |
| House on leased land | Depends on lease | Check lease agreement — assignment clauses vary |
| Land held via Thai company | Depends on shareholding | Complex — seek specialist legal advice |
| Thai bank accounts | Inheritable | Via Thai will or intestacy process |
If you own land (or a villa on land you own), you have a few planning options. You can hold the land through a Thai company and ensure the shares are properly structured for succession. You can have the land pass to a Thai spouse or Thai-national children. Or you can accept that the land will need to be sold on your death and plan accordingly — ring-fencing the sale proceeds for your foreign heirs.
For property planning in Phuket, our guide to buying property as a foreigner covers condo versus villa structures in detail. If you own a villa in areas like Surin, Bang Tao, or Rawai, talk to a property lawyer about succession planning before it becomes urgent.
Need Help Structuring Your Thai Estate?
A Phuket-based lawyer with expat estate experience can review your assets, draft a Thai will, and advise on property structures — usually in a single consultation.

List your Thai assets
Write down every asset you hold in Thailand: condo title deed numbers, bank account numbers, vehicle registration plates, insurance policy numbers, and approximate values. This becomes the backbone of the will.
Choose an executor
Your executor (ผู้จัดการมรดก) manages the estate administration after your death. This can be a Thai national (a trusted friend, Thai spouse, or professional lawyer). Choose someone who is physically in Thailand and legally capable — not someone who would need to fly in from overseas to start the process.
Engage a Phuket lawyer
Find a bilingual (Thai/English) lawyer with expat estate experience. In Phuket, there are several firms serving the expat community around Phuket Town and Bang Tao. Expect a first consultation to cost ฿0–฿2,000; the will itself ฿5,000–฿15,000 for straightforward estates.
Draft and review the Thai will
Your lawyer will draft a bilingual will. Review the Thai text carefully (have a second translation done if you're uncertain). Ensure every asset and beneficiary is correctly named with full legal names and ID numbers where applicable.
Sign with two witnesses
Sign in front of two witnesses who are not beneficiaries under the will. Witnesses must also sign. All three signatures must be made at the same time and place. Your lawyer's office will usually provide the witnesses.
Store safely and update your home-country records
Keep the original Thai will somewhere safe — preferably with your lawyer who can also store a certified copy. Tell your home-country executor that a Thai will exists and how to contact the Thai lawyer. Update this information whenever your Thai assets change significantly.
Review every 3–5 years
If you buy a new condo, change banks, or your family situation changes (marriage, divorce, new children), update your Thai will. An outdated will can create as many problems as no will at all.
Thai Bank Accounts: Practical Steps
Your Thai bank accounts (KBank, Bangkok Bank, SCB, Krungthai) are relatively straightforward to transfer — but only if there's a valid will or the accounts are set up correctly. Here's what to know:
Most Thai banks allow you to nominate a beneficiary for accounts. Some branches in tourist-heavy areas like Phuket Town's Yaowarat Road or Patong have staff experienced with expat accounts — ask specifically about a beneficiary designation when you open or review your account. This is separate from your will and can enable a faster release of funds.
For fixed deposits being used to support a retirement visa (the ฿800,000 requirement), discuss with your lawyer how these should be addressed in the will — your heirs will need clear documentation that the funds can be released once the visa is no longer active.
Life Insurance as an Estate Planning Tool
Many expats in Phuket use Thai life insurance policies both for healthcare coverage and as a savings/investment vehicle. These policies sit outside your estate for inheritance purposes if you've named a beneficiary — the payout goes directly to your named beneficiary without going through probate, regardless of what your will says.
Review your policy documents and confirm who is named as beneficiary. If you've never explicitly named one, the payout falls into your estate and goes through the standard probate process. Cigna and Pacific Cross, two of the most common insurers among Phuket expats, allow beneficiary designations — check with your insurer directly.
For comprehensive health insurance planning in Phuket, see our healthcare guide for retirees which covers policy types and insurers in detail.
The LTR Visa Angle
If you hold a Long-Term Resident (LTR) visa, note that the visa itself is non-transferable and terminates on your death. Your heirs don't inherit the visa status. However, any assets you hold in Thailand because of the LTR (investments, bank deposits) are subject to the same Thai succession rules as any other expat's assets. The LTR visa doesn't create any special inheritance protections or complications — your Thai will covers everything.
Costs: What to Budget
| Service | Cost Range (THB) | Notes |
|---|---|---|
| Simple Thai will (single person) | ฿5,000–฿15,000 | Standard expat estate |
| Bilingual will (Thai + English) | ฿8,000–฿20,000 | Recommended for clarity |
| Couple's wills (2 people) | ฿12,000–฿30,000 | Usually discounted package |
| Complex estate (property + company) | ฿20,000–฿60,000+ | Multiple consultations likely |
| Thai will with power of attorney | ฿10,000–฿25,000 | Includes POA for incapacity |
| Certified translation (foreign will) | ฿3,000–฿8,000 | Per document, certified translator |
| Probate/estate administration fee | ฿15,000–฿50,000+ | After death, depends on complexity |
What About a Power of Attorney?
Estate planning isn't only about what happens when you die. A Thai Power of Attorney (POA) lets someone you trust manage your affairs if you're incapacitated — perhaps after a major medical event. For Phuket expats, this is especially relevant if your family is overseas.
A Thai POA can authorise your designated person to manage bank accounts, sell property, handle legal matters, and deal with government departments on your behalf. Many Phuket lawyers will draft a POA at the same time as your will for a modest additional fee.
If you're also thinking about retirement visa requirements such as the ฿800,000 bank deposit, a POA can ensure someone can manage these funds on your behalf if needed.

Find a Phuket Estate Lawyer →Common Mistakes Phuket Expats Make
After living here six years and watching the expat community navigate these issues, the same mistakes come up again and again. First is doing nothing — assuming that because they have a will at home, Thailand is covered. Second is making their spouse or child a witness to the Thai will, which in Thailand invalidates any bequest to that person. Third is neglecting to update the will after buying a second property or opening a new bank account. Fourth is choosing an executor who lives overseas and has never dealt with the Thai court system.
The fifth mistake, and probably the most expensive, is holding property in a nominee Thai company structure without properly planning for company succession. This is an area where you genuinely need specialist legal advice — the rules are complex and getting them wrong has serious consequences.
