Wills and inheritance, in outline

If you own anything in Thailand — a condo, a bank account, a vehicle — a Thai will can save your heirs a great deal of difficulty later.

No will? A statutory order applies

Without a will, the Civil and Commercial Code distributes an estate among classes of statutory heirs, broadly in this order of priority: descendants; parents; full-blood siblings; half-blood siblings; grandparents; then uncles and aunts. A surviving spouse is always an heir, taking a share alongside whichever class inherits, and first taking their own share of the marital property — see family law.

Making a valid Thai will

• Standard written will: in writing, dated, signed before at least two witnesses who sign too. The most common form.
• Holographic will: entirely handwritten, dated and signed by the testator — no witnesses needed.
• Official will at the amphur: declared before the district officer with witnesses — generally harder to challenge later.
• Beneficiaries, and their spouses, should not act as witnesses, or their gift can fail.

Foreign wills and foreign assets

Thailand can recognise a foreign will, but using one here generally means certified translation, legalisation and slower probate — see notarisation & documents. Many people use a Thai will for Thai assets and a home-country will for everything else, carefully worded so neither revokes the other.

Probate is usually required

Banks, the Land Office and vehicle registries will generally not release or transfer a deceased person’s assets without a court-appointed estate administrator. That means a petition to the court and a hearing before administration begins — often straightforward when documents are in order, and painful when they are not. Gathering the death certificate, house registration, identification, the will (if any) and land documents early is usually what determines how smoothly this goes.

When heirs disagree

Disputes tend to fall into recurring patterns: a will that favours one heir over others, land assumed to be split evenly among siblings but occupied by only one of them, or a previously unknown heir surfacing after administration has started. Court-led mediation resolves many of these before a full trial — see the Thai legal system — but a formal objection to a proposed administrator can pause the whole process for some time, so early, documented communication between heirs is worth a great deal.

The estate administrator’s job

Once appointed, an estate administrator has a legal duty to identify assets and debts, pay the estate’s liabilities, and distribute what remains to the heirs according to the will or the statutory order — keeping records and acting honestly, not simply taking control of the assets. An administrator who mismanages or misappropriates estate property can be removed by the court and held liable to the heirs. Anyone asked to act as administrator should understand this is a real fiduciary responsibility, not an honorary title.

Debts and taxes come out of the estate first

An estate’s debts — and any tax owed on it — are generally settled before heirs receive their shares, not after; an heir who receives property is not personally liable for the deceased’s debts beyond the value of what they inherit. Thailand also has an inheritance tax regime that applies above a threshold and mainly to larger estates, alongside other taxes that can apply to specific asset transfers; see tax basics for the general shape, and confirm the current position with a lawyer or accountant rather than assuming an estate is too modest to be affected.

Digital assets and modern estate planning

Online banking access, cryptocurrency, domain names and other digital assets do not fit neatly into a probate process designed around physical documents and registries, and a password kept only in someone’s head can effectively orphan an asset. If digital assets matter to your estate, document what exists and how an administrator could access or recover it, in a way that does not itself create a security risk while you are alive — a lawyer experienced in estate planning can advise on a sensible approach.

Business owners and life insurance

A business owner’s will should address what happens to company shares on death — many Thai company articles or shareholder agreements restrict who shares can pass to, which can create friction with a will that assumes an heir will simply step into the owner’s role; see business & foreign ownership. Life insurance with a named beneficiary generally pays out directly to that beneficiary outside the probate process, which is one reason some people use it to give heirs faster access to funds than an estate administration can provide.
