Why won&#8217;t the Bangkok bank release his account?&#8221; The answer decides months of their lives. Probate of a foreign will in Thailand, specifically the <strong>probate foreign will thailand<\/strong> process, is possible, and Thai law accepts your US, UK, Canadian, or Australian will as formally valid in most cases. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">But no Thai bank, no Land Office, and no vehicle registry will act on that will, or on any foreign probate order, until a Thai court appoints an estate administrator.

The Act on Conflict of Laws B.E. 2481 (1938) answers this, and the answer is usually yes. A will signed in London under English formalities, or in Texas under Texas formalities, satisfies Thai form requirements through Section 40 of that Act.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Second, enforcement. Thai banks and land officials act on one document only: a Thai court order appointing an estate administrator (\u0e1c\u0e39\u0e49\u0e08\u0e31\u0e14\u0e01\u0e32\u0e23\u0e21\u0e23\u0e14\u0e01), followed by the certificate confirming no appeal was filed. A UK Grant of Probate or a US Letters Testamentary carries no force here. Thai authorities do not execute foreign court orders in succession matters. Your family must petition a Thai court, file the foreign will with certified translations, and wait for the appointment.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">That gap between validity and enforcement is where the delays, the frozen accounts, and the legal fees live. It starts the moment succession opens: under <a href=\"https:\/\/www.thailawonline.com\/th\/thai-civil-code\/section-1599\/\">Section 1599 of the Civil and Commercial Code<\/a>, the estate devolves on the heirs at the instant of death, and <a href=\"https:\/\/www.thailawonline.com\/th\/thai-civil-code\/section-1600\/\">Section 1600<\/a> defines that estate as all property, rights, duties, and liabilities of the deceased. The rights exist immediately. Access to them does not.<\/p>\n\n\n\n<h2 id=\"the-law-conflict-of-laws-act-sections-37-to-42-explained\" class=\"wp-block-heading\">The law: Conflict of Laws Act sections 37 to 42 explained<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The Act on Conflict of Laws B.E. 2481 (1938) contains the five sections that decide every foreign-will case. Competing guides collapse these into &#8220;translate and legalize it.&#8221; The statute does more work than that. You can read the codes these rules interact with in our free <a href=\"https:\/\/www.thailawonline.com\/th\/thai-law-library\/\">\u0e2b\u0e49\u0e2d\u0e07\u0e2a\u0e21\u0e38\u0e14\u0e01\u0e0e\u0e2b\u0e21\u0e32\u0e22\u0e44\u0e17\u0e22<\/a>.<\/p>\n\n\n\n<h3 id=\"form-of-the-will-section-40-nationality-law-or-place-of-execution\" class=\"wp-block-heading\">Form of the will (Section 40): nationality law or place of execution<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Section 40 validates a will as to form if it complies with either the law of the testator&#8217;s nationality or the law of the country where the will was made. A British citizen who signed a will in England under the Wills Act 1837 formalities passes this test twice over. An American who signed a will in Thailand passes if the will meets either US state formalities (nationality) or Thai formalities. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The Thai forms sit in <a href=\"https:\/\/www.thailawonline.com\/th\/thai-civil-code\/book-6-succession\/\">\u0e2b\u0e19\u0e31\u0e07\u0e2a\u0e37\u0e2d\u0e40\u0e25\u0e48\u0e21\u0e17\u0e35\u0e48 6 \u0e41\u0e2b\u0e48\u0e07\u0e1b\u0e23\u0e30\u0e21\u0e27\u0e25\u0e01\u0e0e\u0e2b\u0e21\u0e32\u0e22\u0e41\u0e1e\u0e48\u0e07\u0e41\u0e25\u0e30\u0e1e\u0e32\u0e13\u0e34\u0e0a\u0e22\u0e4c<\/a>: the ordinary written will with two witnesses under <a href=\"https:\/\/www.thailawonline.com\/th\/thai-civil-code\/section-1656\/\">\u0e21\u0e32\u0e15\u0e23\u0e32 1656<\/a>, the handwritten holographic will under <a href=\"https:\/\/www.thailawonline.com\/th\/thai-civil-code\/section-1657\/\">\u0e21\u0e32\u0e15\u0e23\u0e32 1657<\/a>, and the District Office public-document will under <a href=\"https:\/\/www.thailawonline.com\/th\/thai-civil-code\/section-1658\/\">\u0e21\u0e32\u0e15\u0e23\u0e32 1658<\/a>. This double gateway is why Thai courts rarely reject foreign wills on form.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">One trap survives the gateway. <a href=\"https:\/\/www.thailawonline.com\/th\/thai-civil-code\/section-1667\/\">Section 1667<\/a> voids a bequest to anyone who signed the will as a witness, and their spouse. If your home jurisdiction tolerated an interested witness, the Thai court will not.<\/p>\n\n\n\n<h3 id=\"meaning-and-effect-section-41-the-law-of-your-domicile-decides\" class=\"wp-block-heading\">Meaning and effect (Section 41): the law of your domicile decides<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Form is one thing. What the will means is another. Section 41 sends the effects, interpretation, and nullity of a will (or any clause in it) to the law of the testator&#8217;s domicile at death. If your father lived his last years in Manchester, English law governs what &#8220;my residuary estate&#8221; captures and whether a gift lapsed. Section 42 applies the same domicile logic to revocation, which Thai law separately addresses in <a href=\"https:\/\/www.thailawonline.com\/th\/thai-civil-code\/section-1693\/\">Section 1693<\/a>. This is the two-track analysis most guides skip: Section 40 for form, Section 41 for substance, and the two can point to different countries.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Watch one clause type in particular. <a href=\"https:\/\/www.thailawonline.com\/th\/thai-civil-code\/section-1686\/\">\u0e21\u0e32\u0e15\u0e23\u0e32 1686<\/a> strips any trust created by will of effect in Thailand. Anglo-American wills routinely pour assets into a testamentary trust, and that machinery does nothing for the Thai portion of the estate. We explain the workarounds in our note on <a href=\"https:\/\/www.thailawonline.com\/th\/trusts-in-thailand-foreign-jurisdiction\/\">trusts and foreign jurisdictions<\/a>.<\/p>\n\n\n\n<h3 id=\"thai-land-and-condos-section-37-thai-law-no-exceptions\" class=\"wp-block-heading\">Thai land and condos (Section 37): Thai law, no exceptions<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Section 37 governs succession to immovable property by the law of the place where the property sits. A Bangkok condo passes under Thai law regardless of what any foreign will or foreign statute says. Section 38 sends movable property (bank accounts, vehicles, shares) to the law of the deceased&#8217;s domicile at death. In practice: the foreign will can name the beneficiaries, but the <a href=\"https:\/\/www.thailawonline.com\/th\/thailand-land-code\/\">\u0e1b\u0e23\u0e30\u0e21\u0e27\u0e25\u0e01\u0e0e\u0e2b\u0e21\u0e32\u0e22\u0e17\u0e35\u0e48\u0e14\u0e34\u0e19\u0e02\u0e2d\u0e07\u0e44\u0e17\u0e22<\/a> controls how Thai real estate transfers, including the foreign-ownership restrictions that survive death.

You need the original foreign will (or a certified copy from the foreign probate registry), the death certificate, proof of kinship or entitlement, and an inventory of the Thai assets: title deeds, bank books, share certificates, vehicle registration.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Every foreign document must be translated into Thai by a certified translator. On legalization, the rules are changing: <a href=\"https:\/\/www.hcch.net\/en\/news-archive\/details\/?varevent=1158\" target=\"_blank\" rel=\"noopener\">Thailand deposited its accession to the Hague Apostille Convention on 30 June 2026<\/a>, and the Convention enters into force for Thailand on 28 February 2027. Until that date, an apostille alone does nothing here. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Foreign documents go through the traditional chain covered in our guide to <a href=\"https:\/\/www.thailawonline.com\/th\/legalization-of-documents-in-thailand\/\">legalization of documents in Thailand<\/a>: certification in the home country, authentication by the Thai embassy or consulate there, then legalization by the Department of Consular Affairs of the Thai Ministry of Foreign Affairs. From 28 February 2027, a single apostille from a member country should replace that chain for public documents. Budget weeks either way, and start the paperwork before filing anything.<\/p>\n\n\n\n<h3 id=\"who-petitions-and-where-ccc-s-1713-cpc-s-4-quater\" class=\"wp-block-heading\">Who petitions and where (CCC s.1713, CPC s.4 quater)<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/www.thailawonline.com\/th\/thai-civil-code\/section-1713\/\">Section 1713 of the Civil and Commercial Code<\/a> lists who may ask the court to appoint an estate administrator: an heir, a legatee under the will, an interested person, or the public prosecutor. Venue comes from a different code. <a href=\"https:\/\/www.thailawonline.com\/th\/thai-civil-procedure-code\/section-4-4\/\">Section 4 quater of the Civil Procedure Code<\/a> fixes the court by the deceased&#8217;s domicile at the moment of death, and where the deceased had no Thai domicile, by the location of the estate property. A retiree who died in Florida owning a Phuket condo answers to the Phuket Provincial Court. The Supreme Court has enforced this strictly: estates of relatives domiciled elsewhere cannot be bundled into one petition just because the heirs overlap.<\/p>\n\n\n\n<h3 id=\"the-hearing-the-30-day-appeal-window-the-final-certificate\" class=\"wp-block-heading\">The hearing, the 30-day appeal window, the final certificate<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The court schedules a hearing, typically two to three months after filing. The proposed administrator should attend in person. Courts want to see the person they are appointing, question them about the estate, and confirm no heir objects. If you have never seen a Thai courtroom, read <a href=\"https:\/\/www.thailawonline.com\/th\/what-to-know-before-you-go-to-court-in-thailand\/\">\u0e2a\u0e34\u0e48\u0e07\u0e17\u0e35\u0e48\u0e04\u0e27\u0e23\u0e23\u0e39\u0e49\u0e01\u0e48\u0e2d\u0e19\u0e02\u0e36\u0e49\u0e19\u0e28\u0e32\u0e25\u0e43\u0e19\u0e1b\u0e23\u0e30\u0e40\u0e17\u0e28\u0e44\u0e17\u0e22<\/a> first. If the judge grants the petition, the appointment order does not become usable immediately. A 30-day appeal window runs first. Once it closes with no appeal, the court issues the certificate of finality (often called the Certificate of No Appeal), and this is the document banks and the Land Office actually honor.<\/p>\n\n\n\n<h2 id=\"who-can-be-estate-administrator-including-foreigners\" class=\"wp-block-heading\">Who can be estate administrator, including foreigners<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/www.thailawonline.com\/th\/thai-civil-code\/section-1711\/\">Section 1711<\/a> onward governs administrators: appointment, powers, duties, and removal. <a href=\"https:\/\/www.thailawonline.com\/th\/thai-civil-code\/section-1718\/\">Section 1718<\/a> disqualifies three groups: persons not sui juris (minors), persons of unsound mind or adjudged quasi-incompetent, and persons adjudged bankrupt.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Foreigners appear nowhere on that list. Thai courts appoint foreign administrators regularly, including the executor named in the foreign will. The practical friction is language and presence: proceedings run in Thai, and the administrator must sign documents at banks and the Land Office after appointment. Many foreign executors grant a <a href=\"https:\/\/www.thailawonline.com\/th\/power-of-attorneys-for-thailand\/\">\u0e2b\u0e19\u0e31\u0e07\u0e2a\u0e37\u0e2d\u0e21\u0e2d\u0e1a\u0e2d\u0e33\u0e19\u0e32\u0e08<\/a> to a Thai lawyer for the paperwork while attending the hearing themselves.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The job carries real duties. Under <a href=\"https:\/\/www.thailawonline.com\/th\/thai-civil-code\/section-1719\/\">Section 1719<\/a> the administrator must carry out the will and manage the estate, and <a href=\"https:\/\/www.thailawonline.com\/th\/thai-civil-code\/section-1729\/\">Section 1729<\/a> requires a full inventory within one month of appointment. An administrator who mismanages the estate can be removed on petition under <a href=\"https:\/\/www.thailawonline.com\/th\/thai-civil-code\/section-1727\/\">Section 1727<\/a>.<\/p>\n\n\n\n<h2 id=\"what-it-costs-and-how-long-it-takes\" class=\"wp-block-heading\">What it costs and how long it takes<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Straightforward Thai probate, with a Thai will and no dispute, runs four to six months from filing to certificate. A foreign will adds the translation and legalization chain, and often an affidavit of foreign law, which together add six to twelve months in typical cases. Contested estates run years. After the certificate issues, transferring the assets themselves (Land Office registration, bank releases, share transfers) takes another two to six months, and the <a href=\"https:\/\/www.thailawonline.com\/th\/property-taxes-in-thailand\/\">\u0e20\u0e32\u0e29\u0e35\u0e41\u0e25\u0e30\u0e04\u0e48\u0e32\u0e18\u0e23\u0e23\u0e21\u0e40\u0e19\u0e35\u0e22\u0e21\u0e01\u0e32\u0e23\u0e42\u0e2d\u0e19<\/a> fall due at that point.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Where the time goes: document legalization before filing (one to three months), waiting for the hearing date (two to three months), the 30-day appeal window, then the asset-by-asset transfer work. The court filing fee for an uncontested petition runs a few hundred baht, with related court expenses rarely passing a few thousand. Certified translation, legalization, and legal fees form the real cost, and they scale with the number of foreign documents. Compare that with the cost of simply <a href=\"https:\/\/www.thailawonline.com\/th\/will-cost-thailand\/\">\u0e01\u0e32\u0e23\u0e17\u0e33\u0e1e\u0e34\u0e19\u0e31\u0e22\u0e01\u0e23\u0e23\u0e21\u0e44\u0e17\u0e22<\/a>, which starts under 4,000 baht.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">One deadline your family cannot miss: <a href=\"https:\/\/www.thailawonline.com\/th\/thai-civil-code\/section-1754\/\">\u0e21\u0e32\u0e15\u0e23\u0e32 1754<\/a> bars inheritance claims one year after the heir learns of the right, and ten years after the death. Waiting for a foreign probate to conclude before starting in Thailand burns that clock.<\/p>\n\n\n\n<h2 id=\"the-affidavit-of-foreign-law-when-thai-courts-need-proof-of-your-home-law\" class=\"wp-block-heading\">The affidavit of foreign law: when Thai courts need proof of your home law<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Thai judges apply Thai law on their own. Foreign law they treat as fact, and facts need evidence. When Section 41 makes English or Californian law govern the interpretation of the will, the petitioner proves that law, usually through an affidavit of foreign law: a sworn statement by a lawyer qualified in the home jurisdiction explaining the relevant rules. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Without it, the court cannot apply the foreign law, and Thai law fills the gap by default. You need the affidavit when the will&#8217;s meaning, the executor&#8217;s authority, or a beneficiary&#8217;s entitlement turns on home-country law. You can skip it when the will is simple, the heirs agree, and the estate is a bank account plus a condo passing under Thai law anyway.<\/p>\n\n\n\n<h2 id=\"why-a-separate-thai-will-is-still-the-better-route-and-when-it-is-not\" class=\"wp-block-heading\">Why a separate Thai will is still the better route (and when it is not)<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The statutes explain the advice every Thai lawyer gives. A foreign will works through Section 40, but it drags the estate through translation, legalization, and foreign-law proof. A Thai will covering only Thai assets, drafted in Thai form, skips all three. The court reads it directly. Probate shortens by months and the legalization budget disappears.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Keep both wills, scoped so neither revokes the other: the Thai will for Thai assets, the home will for everything else. The exception: if your Thai holdings are trivial or you are mid-move, one worldwide will may be simpler, and Section 40 will carry it.

We maintain an analysis of more than 75 <a href=\"https:\/\/www.thailawonline.com\/th\/last-will-in-thailand\/supreme-court-decisions-last-will-thailand\/\">Supreme Court decisions on Thai wills<\/a> from 1936 to 2025, and a broader collection of <a href=\"https:\/\/www.thailawonline.com\/th\/supreme-court-decisions\/\">curated Dika rulings by topic<\/a>.

The Grant helps as evidence (it shows the will was proved at home), but your family still petitions a Thai court for a Thai administrator appointment before any Thai asset moves.<\/p>\n\n<\/div>\n<\/div>\n<div id=\"faq-question-1785545307355\" class=\"rank-math-list-item\">\n<h3 class=\"rank-math-question\">Can I be administrator from abroad without travelling?<\/h3>\n<div class=\"rank-math-answer\">\n\n<p>You can start the process from abroad through a power of attorney to a Thai lawyer, who prepares and files the petition. Plan to attend the court hearing in person; judges expect to see the proposed administrator, and courts only rarely excuse attendance. After appointment, a power of attorney covers most of the bank and Land Office work.<\/p>\n\n<\/div>\n<\/div>\n<div id=\"faq-question-1785545308323\" class=\"rank-math-list-item\">\n<h3 class=\"rank-math-question\">What happens to my Thai bank account when I die?<\/h3>\n<div class=\"rank-math-answer\">\n\n<p>The bank freezes the account when notified of the death. It releases funds against the Thai court&#8217;s administrator appointment order plus the certificate confirming the 30-day appeal window closed. No foreign document substitutes, and joint signatories lose access too. Our guide to the <a href=\"https:\/\/www.thailawonline.com\/th\/death-of-a-foreigner-in-thailand\/\">death of a foreigner in Thailand<\/a> covers the first practical steps for the family.<\/p>\n\n<\/div>\n<\/div>\n<div id=\"faq-question-1785545342638\" class=\"rank-math-list-item\">\n<h3 class=\"rank-math-question\">Does Thailand have inheritance tax on probated assets?<\/h3>\n<div class=\"rank-math-answer\">\n\n<p>Thailand taxes inheritances above 100 million baht per heir under the Inheritance Tax Act B.E. 2558 (2015): 5% for ascendants and descendants, 10% for others, with spouses exempt. Most foreign estates fall under the threshold.

Section 40 tests validity against the testator&#8217;s nationality law or the place of signing, so the language of the will never invalidates it. Translation quality matters more, because the Thai court reads only the Thai text.<\/p>\n\n<\/div>\n<\/div>\n<div id=\"faq-question-1785545366871\" class=\"rank-math-list-item\">\n<h3 class=\"rank-math-question\">What if there is no will at all?<\/h3>\n<div class=\"rank-math-answer\">\n\n<p>The estate passes by intestacy. <a href=\"https:\/\/www.thailawonline.com\/th\/thai-civil-code\/section-1620\/\">Section 1620<\/a> sends it to the statutory heirs, ranked in the six classes of <a href=\"https:\/\/www.thailawonline.com\/th\/thai-civil-code\/section-1629\/\">\u0e21\u0e32\u0e15\u0e23\u0e32 1629<\/a>, with the surviving spouse taking a share under <a href=\"https:\/\/www.thailawonline.com\/th\/thai-civil-code\/section-1635\/\">Section 1635<\/a>. The Thai court still appoints an administrator on petition. See <a href=\"https:\/\/www.thailawonline.com\/th\/if-you-die-without-a-will-in-thailand\/\">what happens if you die without a will in Thailand<\/a>.<\/p>\n\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n\n\n<h3 id=\"what-if-there-is-no-will-at-all\" class=\"wp-block-heading\">\u0e1a\u0e17\u0e2a\u0e23\u0e38\u0e1b<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Probate of a foreign will in Thailand follows a clear statutory path: Section 40 of the Conflict of Laws Act carries your will through the validity gate, Sections 37, 38, and 41 decide which country&#8217;s law governs each asset and each clause, and the Civil and Commercial Code hands enforcement to a Thai-court-appointed administrator. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The process works. It just works slowly, in Thai, and only through a Thai courtroom. If you hold Thai assets today, a bilingual Thai will costs a fraction of what the legalization chain will cost your family later. If you are already facing a Thai probate with a foreign will, start the document legalization now and get the petition filed.
