Powers of attorney for use in Thailand
In short
A power of attorney lets someone act for you in Thailand when you cannot attend. Thai authorities generally expect a Thai-language instrument, correctly stamped where duty applies, and — if signed abroad — authenticated so the receiving office can rely on the signature.
Scope matters more than form. Many Thai offices, including the Land Department and the Department of Business Development, use their own prescribed power-of-attorney forms and will reject a general worldwide POA. Confirm which form the receiving office uses before drafting anything.
A POA signed outside Thailand is normally notarised locally and then authenticated. Since 22 December 2024 Thailand is a party to the HCCH Apostille Convention, so for documents from other contracting states an apostille commonly replaces consular legalisation — but the receiving Thai office still decides what it accepts, so confirm first.
What we need from you
- The exact transaction and the office that will receive the POA
- Full name and ID/passport details of grantor and attorney
- Where the document will be signed and witnessed
- Any prescribed form the office requires
Watch out
Drafting a broad POA and hoping it covers everything. Thai offices read scope narrowly and reject anything that does not name the transaction. Scope, turnaround and fees are confirmed by IVC staff by phone, LINE or email — this site does not publish prices.
