Cross-Border Wills, Estate Planning and Inheritance in Thailand

Each country applies its own probate process to assets located there. A Thai court dealing with a Thai condominium wants a will it can read and apply: in Thai, in a recognised form, without a foreign probate having to be proven first. A foreign court dealing with assets in its country wants the same in its own language and form. A single will trying to do both often does neither quickly.

The standard solution for internationally mobile families is a set of coordinated wills: a Thai will limited to Thai assets, and a home-country will limited to assets there. Each will must be drafted so it does not revoke the other — the classic trap is the clause revoking 'all previous wills', which silently cancels the foreign document.

Some countries add another layer: forced-heirship rules that reserve shares for children or spouses regardless of the will, or community-property regimes that limit what a spouse can give away. Where those rules apply to the client, we flag the conflict and coordinate with counsel in that country rather than pretending the Thai will controls everything.

The Thai Civil and Commercial Code recognises several forms of will. The common practical form is a written will signed by the testator before at least two witnesses who sign at the same time. A will can also be deposited with the district office, which adds a layer of official custody. Holograph and other forms exist but are rarely the right choice for significant estates.

Details matter: witnesses must be competent and should not be beneficiaries; the will should identify assets and executors clearly; and a Thai-language original with a certified translation for the client avoids disputes about meaning later.

We also advise on the practical side: telling the executor where the original is kept, reviewing the will after major life events — marriage, divorce, a child, a major purchase — and keeping the asset schedule current so the executor is not left guessing.

In Thailand, an estate is administered by a court-appointed administrator. Until the court order issues, banks will not release accounts, the Land Office will not transfer title, and buyers will not complete purchases of estate property. The application is made to the court with jurisdiction, supported by the death certificate, the will if there is one, evidence of the heirs and the proposed administrator's consent.

Where heirs live abroad, the file needs notarised and legalised powers of attorney and translations, which take time to assemble. Starting early and preparing the document set in parallel with the court filing is what separates a six-month administration from a two-year one.

Once appointed, the administrator collects the assets, settles debts and taxes, and distributes the balance under the will or the intestacy rules. We act as administrator where the family asks, or advise the family's own administrator through the process.

Condominium units within the foreign ownership quota can generally be inherited and registered to a foreign heir, subject to the quota and the funds-remittance evidence the Land Office requires. Land is different: foreigners generally cannot register land ownership, and a foreign heir who inherits land is normally required to dispose of it within a statutory period. The heir receives the sale proceeds, not the title.

Company shares pass under the will or intestacy, but the transfer must be recorded in the share register and filed with the Department of Business Development. Where the company holds property or a business licence, the share transfer can have regulatory consequences that need checking before the transfer is made.

Bank accounts are released to the administrator against the court order. Accounts abroad are handled under that country's process, which is where the coordinated foreign will does its work.

Thailand has an inheritance tax that applies above a substantial threshold, with exemptions for spouses and reduced effective burdens for close family. Most estates fall below the threshold, but larger estates — particularly those with Bangkok property — should be assessed early so the tax is planned rather than discovered. We coordinate with tax advisers on the assessment and the filing.

For heirs abroad, the final step is often repatriating sale proceeds. Thai exchange-control rules allow repatriation of inheritance and sale proceeds with the right bank documentation, and the paper trail — court order, transfer records, tax receipts — is what the bank needs to see. We assemble that trail as the administration proceeds, not after.

Where the deceased's home country also taxes inheritances or worldwide estates, we coordinate with foreign tax counsel so the estate is not taxed twice where a treaty or credit prevents it.

The best estate planning happens years before it is needed. For a foreign resident in Thailand, a sensible package is usually: a Thai will for Thai assets, a reviewed home-country will for assets there, a durable power of attorney or equivalent for incapacity, and a clear asset schedule that the family can find.

Family situations that cross borders — a Thai spouse, children of two nationalities, property in three countries — benefit from a single planning conversation that maps every asset to the rule that governs it. That map is also the document that makes the eventual administration fast.

We offer that planning conversation as a structured review: assets, family, existing documents, conflicts and the steps to close the gaps. The output is a written plan the client can act on with us or with counsel at home.
