Inheritance and wills in Thailand
If you own anything in Thailand — a condo, a bank account, a vehicle — a Thai will saves your heirs months of difficulty. Here is how succession works.
No will? The statutory order applies
Without a will, the Civil and Commercial Code distributes the estate among six classes of statutory heirs, in order of priority:
- Descendants (children, grandchildren)
- Parents
- Full-blood brothers and sisters
- Half-blood brothers and sisters
- Grandparents
- Uncles and aunts
A surviving spouse is always an heir, taking a share alongside whichever class inherits (and the spouse first takes their half of the marital property — see family law). Children and parents in class 1 and 2 share together in many situations; the exact split depends on who survives.
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 — 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 means certified translation, legalisation and slower probate. The practical pattern most lawyers recommend: a Thai will for Thai assets and a home-country will for everything else, each 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, a hearing, and then administration of the estate — straightforward when documents are in order, painful when they are not. Start by gathering the death certificate, house registration, ID copies, the will if there is one, and every land document you can find; missing paperwork, not the law itself, is what usually slows an estate down. Inheritance tax currently applies only to large estates above a high threshold, with close relatives taxed at reduced rates; check current thresholds when planning.
When heirs disagree
Disputes tend to fall into a few recurring shapes: a will that favours one child over others (valid on its face, but sometimes challenged on grounds of capacity or undue influence); land held in a parent’s name that several siblings assume will be split evenly, only to find one sibling already living on and improving part of it; or a previously unknown heir — commonly a child from an earlier relationship — surfacing after administration has already started. Court-led mediation resolves many of these before a full trial (see civil procedure), but a formal objection to a proposed administrator can freeze the whole process for months, so early, documented communication between heirs is worth far more than it costs.
Assets that bypass probate
Not everything an estate holds has to pass through the administrator. A life insurance policy pays the named beneficiary directly, and some bank accounts and provident or pension funds have their own beneficiary-nomination mechanisms that operate outside the will. Checking and updating these nominations — especially after a marriage, divorce or the birth of a child — is inexpensive estate planning that many families never get around to.
Lifetime gifts versus inheritance
Some families transfer property before death rather than leaving it to pass through an estate — a lifetime gift of land, for instance, registered at the Land Office while the giver is still alive. This avoids probate for that asset entirely, but gift tax can apply above certain thresholds between non-close relatives, and a gift made shortly before death or while insolvent can sometimes be challenged by creditors or disappointed heirs. It is a genuine planning tool, not a shortcut around the law — discuss timing and tax exposure with a lawyer before relying on it, and see property & land for how a transfer is actually registered.
