Substantive rules
Even if formally valid, transfers of Thai immovable property follow Thai law, including restrictions on foreign land ownership.
Original or certified copy
Prepare the original or a copy certified by the foreign court or authority, plus any foreign probate order.
Authentication and translation
Foreign documents usually need notarisation and legalisation through the applicable channel, then a certified Thai translation.
Proof of foreign law
Thai courts may require evidence of the foreign formal requirements, such as an expert opinion on that law.
Multiple wills
Check dates and revocation clauses, as a later will may revoke earlier ones to the extent of conflict.
