Dual will strategy for Thai nationals and US persons holding assets in Thailand and the United States.
AI Quick Answer · Speakable
The US taxes worldwide estates of citizens and long-term green-card holders and applies a USD 60,000 exemption to non-resident aliens holding US-situs assets. A Thai-domicile testator with US brokerage or real property should execute both a US will (state-specific, 2 witnesses) and a Thai will with a mutual non-revocation clause and, where possible, hold US real estate through a revocable living trust to avoid probate.
Quick facts
- Succession law: State-by-state common-law systems · Uniform Probate Code adopted in 18 states · Louisiana follows a civil-law forced-heirship regime.
- Forced heirship: No forced heirship outside Louisiana. Surviving spouse retains an elective share (typically one-third) that overrides disinheriting clauses.
- Accepted will formats: Attested will with 2 witnesses is universal. Holographic wills are recognised in about 26 states. A self-proving affidavit accelerates probate in every jurisdiction.
- Inheritance tax: Federal estate tax: USD 13.61 M exemption (2024) with a 40% top rate. 12 states plus DC levy an additional estate or inheritance tax. Non-resident aliens receive only a USD 60,000 exemption on US-situs assets.
- Probate timeline: 6–18 months for a simple estate; 2–5 years when the estate is contested or holds foreign assets requiring ancillary probate.
- Treaty position: No US-Thailand estate-tax treaty. The 1996 US-Thailand income-tax treaty covers income only.
- Package fee: From THB 60,000 — bundled US will drafting plus a Thai companion will.
Key risk for Thai nationals & expats
A Thai citizen holding a US green card for 8 of the last 15 years becomes a 'covered expatriate' when the card is surrendered, triggering the mark-to-market exit tax. US-situs assets held by a non-resident alien above USD 60,000 are exposed to the 40% federal estate tax even if the decedent never lived in the US.
Probate process in United States
File the will with the probate court in the decedent's domicile state, appoint an executor, publish creditor notices, pay valid claims and file estate/inheritance tax returns before distribution.
Recommended strategy
1) Execute a US will for US-situs assets and a Thai will for Thai-situs assets with a mutual non-revocation clause. 2) Move US real estate into a revocable living trust to skip probate. 3) Own high-value US insurance policies through a non-US spouse or ILIT.

Do I need ancillary probate in Thailand for US-held Thai property?
Yes when title is registered in Thailand. The Thai probate court recognises the executor named in a foreign will but requires a certified translation, MFA legalisation and — post-25 December 2025 — an Apostille from the US Secretary of State's office rather than the previous embassy chain.
Can a US revocable trust hold Thai real estate?
Direct foreign ownership of Thai land is restricted. Use a Thai company, a 30-year lease or a superficies right instead; the trust can hold the shares or lease interest, not the freehold title.
