Ministerial Regulation on Making Wills and Declarations of Intent Regarding Inheritance B.E. 2569
As Thailand continues to refine its legal framework to accommodate a growing expatriate and foreign investment community, the Ministry of Interior has introduced the first major overhaul of public will procedures in over six decades. The Ministerial Regulation on Making Wills and Declarations of Intent Regarding Inheritance B.E. 2569 (2026), published in the Royal Gazette on 22 January 2026 and effective from 24 March 2026, replaces the outdated 1960 rules governing Public Wills and related inheritance declarations.
This update does not alter the substantive inheritance provisions under the Civil and Commercial Code (e.g., forced heirship rules for statutory heirs), but it modernizes administrative processes, standardizes forms, strengthens identity and capacity verification, and clarifies procedures for district office (Amphur) registrations. For expats owning property, bank accounts, vehicles, or other assets in Thailand, or those in mixed-nationality families, these changes make formal estate planning more reliable and less prone to probate delays.
Understanding Public Wills in Thai Law
Under Section 1658 of the Thai Civil and Commercial Code, a Public Will (พินัยกรรมแบบเอกสารฝ่ายเมือง) is one of five recognized will types. It is created directly at a district office (any Amphur, King Amphur, or Bangkok Khet), where the testator verbally declares their wishes to the District Chief or Zone Director in the presence of at least two witnesses. The officer records the declaration in writing, reads it aloud for confirmation, obtains signatures from all parties, registers it officially, and stores the original (with the option for the testator to retain possession via receipt).
This method offers a low-cost, government-supervised option ideal for straightforward estates, but it is conducted entirely in Thai and requires witnesses who understand the language and are not beneficiaries.
The new regulation enhances this process with:
- Updated official forms for consistency nationwide.
- Explicit authority for officials to request additional evidence if there are doubts about the testator’s age, mental capacity, health, or freedom from coercion.
- Clearer guidelines for related declarations, including:
- Disinheritance of statutory heirs (tat thayath doitham mai hai rap moradok).
- Revocation of disinheritance.
- Renunciation of inheritance (sala moradok).
Key Changes and New Requirements Effective 24 March 2026
The regulation applies to Public Wills, Secret Wills, Oral Wills (in limited cases), and the above declarations. Expats should note the following practical impacts:
- Documentation and Verification
Testators must present valid identification (passport with current Thai visa or residence status), house registration (Tabien Baan) if applicable, marriage/divorce certificates (with official translations and MFA certification if foreign-issued), children’s birth certificates (translated if needed), lists of Thai assets, beneficiary details, and proposed executor information. Officials may demand extra proof for capacity concerns.
- Witness Requirements
Witnesses must be at least 20 years old, hold valid ID (Thai ID or passport), understand Thai, and not be beneficiaries or related in ways that create conflicts.
- Language and Process
The entire proceeding is in Thai. Non-fluent expats should bring a qualified Thai translator (or legal advisor) to avoid misunderstandings.
- Storage and Access
The will is registered and stored at the district office. Testators can request possession with a receipt and acknowledgment; a certified copy remains on file. If death occurs before collection, the designated contact must provide identity proof and a death certificate.
- No Appointment Needed
Visits are typically walk-in (arrive early to avoid queues), but preparation is essential.
Why This Matters for Expats in 2026
Many foreigners hold assets in Thailand without a localized will, relying on overseas documents. This can lead to probate delays of 6–18 months and substantial costs. A valid Thai will—whether public or privately drafted—ensures smoother execution under Thai law.
Public Wills suit simple estates (e.g., Thai property distribution to a spouse or children), but for complex situations involving international assets, businesses, trusts, or disputes over forced heirship (where descendants are entitled to reserved portions), a lawyer-drafted private will (often bilingual) remains preferable.
The update reduces ambiguity in district office processes, minimizing disputes and enhancing enforceability—beneficial for Thai-foreign couples, retirees, investors, and digital nomads building lives here.
Practical Recommendations for Foreign Nationals
- Review Existing Plans — If you own Thai assets, ensure you have a Thai-specific will coordinating with any foreign one.
- Prepare in Advance — Gather translated documents, asset inventories, and beneficiary/executor details before visiting an Amphur.
- Consider Professional Assistance — Engage counsel for drafting/review, especially for multi-jurisdictional estates or to navigate forced heirship.
- Update After Life Events — Marriage, divorce, birth of children, or asset changes do not automatically revoke wills—proactively revise.
- Combine Strategies — Use Public Wills for basic official registration where appropriate, but pair with private wills for comprehensive protection.
