Cross-Border Probate & Inheritance Document Support
When an estate crosses a border, the probate court on each side wants proof it can read and verify. ILC prepares death certificates, family status records, wills, renunciations and administrator appointment orders — certified translation, notarial certification and MFA legalization — and coordinates with the foreign lawyer handling the estate.

Moving estate documents between Thailand and a foreign court
Thai documents for a foreign probate
A foreign court or registry may ask for a Thai death certificate, house registration, will, or Thai court order. These are translated, certified, then legalised at the Ministry of Foreign Affairs and the destination embassy. Apostille certificates only apply in Thailand from 28 February 2027; until then the legalisation chain is used.
Foreign documents for a Thai estate
When a foreign heir or deceased is involved, foreign grants of probate, death certificates and relationship documents must be legalised in their country of origin and translated into Thai before a Thai court or land office accepts them.
A foreign grant is not automatically recognised
A probate grant from another country does not by itself let the executor transfer Thai land or bank funds. In most cases a Thai court appointment is still required, using the foreign documents as evidence.
Keep names consistent
Different spellings of names across passports, Thai records and foreign certificates are a common cause of delay. We prepare a name-consistency check and, where needed, a supporting affidavit before filing.

Frequently asked questions
What Thai documents does an overseas probate court usually require?
Commonly the death certificate, the household registration showing the deceased's record, the marriage certificate or family status evidence, the will if made in Thailand, and any Thai court order appointing an estate administrator. Each is certified, translated, legalized by the MFA and often by the receiving country's embassy in Bangkok.
Is a Thai will valid for assets held abroad?
A will validly executed in Thailand is generally recognised for Thai assets, but overseas courts apply their own succession rules and may require a separate grant. Many families keep one will per jurisdiction, carefully drafted so they do not revoke each other. Take local advice in the country where the asset sits before relying on a single document.
Who can be appointed estate administrator in Thailand?
A Thai court appoints the administrator on petition by an heir or an interested party, and the order is what banks and land offices act on. Foreign heirs can be appointed but must appear or act through a lawyer with a legalized power of attorney. We prepare and legalize the documents the petition and the foreign court both need.
How long does the document chain take?
Certified translation is usually two to four business days, MFA Consular legalization two to three business days, and embassy legalization a further one day to two weeks. Obtaining a Thai court order is a separate matter measured in months. We report each stage so the overseas solicitor can plan filings around real dates.
The deceased died overseas. What must be done in Thailand?
The foreign death certificate is apostilled or legalized in the issuing country, translated into Thai, and legalized by the MFA or the Thai embassy abroad before Thai banks, the land office or a Thai court will act on it. Thai district offices may also require registration of the death for a Thai national.
Can you work directly with our solicitor overseas?
Yes. We routinely take instructions from overseas law firms, report in English, supply scanned certified sets ahead of the couriered originals, and issue formal invoices. A single case manager keeps the correspondence in one thread so the file does not fragment across time zones.
