Thai will vs foreign will for assets located in Thailand
Assets located in Thailand — condominiums, bank accounts, shares in Thai companies — almost always require a Thai court to appoint an estate administrator. A will drafted in Thai statutory form lets the court proceed cleanly. A foreign will can be used, but it needs full translation and legalization and may require proof of validity under its own law, which takes longer.
Bottom line: With Thai-situs assets, make a separate Thai will covering only those assets, drafted so it does not accidentally revoke your foreign will.
Side-by-side comparison
| Criterion | A will made under Thai law | A foreign will used in Thailand |
|---|---|---|
| Court involved | Thai court, directly | Thai court, after proving the foreign document |
| Language and form | Thai language, statutory form | Certified translation plus full legalization |
| Overall timeline | Shorter — documents are court-ready | Longer — extra proof steps |
| Dispute risk | Lower when witnesses and form are correct | Higher when wording conflicts with Thai law |
Choose A will made under Thai law when
- You hold Thai property, bank accounts or shares
- You want your family to administer the estate quickly
- You want a Thailand-based administrator named
Choose A foreign will used in Thailand when
- Your main estate is abroad with minor Thai assets
- You already have a worldwide foreign will
- You are not ready to execute documents in Thailand
Documents to prepare
- Testator's Thai ID or passport
- Schedule of Thai assets with title documents and bank records
- Marriage certificate, children's birth certificates or other relationship proof
- Two witnesses who are not beneficiaries
- Any existing foreign will, with translation
Step-by-step process
- Build a current schedule of Thai assets
- Check whether an existing foreign will overlaps or conflicts
- Draft a Thai will limited to Thai assets and name an administrator
- Execute before two qualifying witnesses in statutory form
- Store the original securely and tell the administrator where
- Review after any asset purchase, sale or family status change
Common pitfalls
- A blanket revocation clause that unintentionally kills the foreign will
- Using a beneficiary as a witness, risking that gift
- Naming no administrator, lengthening the court stage
- Failing to update after buying a condo or opening new accounts
Frequently asked questions
- Can a foreigner make a will in Thailand?
- Yes. Foreigners may execute a will in Thai statutory form for assets situated in Thailand; a Thai text with translation keeps it clear for heirs.
- Do we still need a court order if there is a will?
- Usually yes — banks and land offices require a court-appointed administrator. The will makes that step faster and less contentious.
- How is a foreign will translated?
- Into Thai by a translator who certifies the translation, then authenticated through the chain accepted by Thai courts and agencies.
- How do you help?
- We review your cross-border asset structure, draft a Thai will that does not conflict with your foreign will, arrange witnessing, and later handle the administrator petition for the family.
