Power of attorney for use in Thailand
In short
A power of attorney lets an agent act for you in a defined matter — a land office transfer, a company filing, a bank formality. Thai law treats agency under the Civil and Commercial Code, and many offices insist on their own prescribed form rather than a free-text document.
The single most useful step is to ask the receiving office which form it accepts before drafting anything. The Land Department, the Department of Business Development and individual banks each maintain their own templates, and a beautifully drafted general power is routinely refused where a one-page prescribed form would have been accepted.
A power executed abroad normally needs a certification chain before a Thai office will act on it: signature certification where you are, then either an Apostille (for a Contracting Party to the HCCH 1961 Convention, which entered into force for Thailand on 22 December 2024) or the older legalisation route, then a Thai translation certified for the receiving office.
What we need from you
- The exact act the agent must perform, and the office that will receive the document
- Full name of the principal exactly as in the passport, and of the agent
- Property, company or account identifiers involved
- Where the document will be signed, and whether a notary is available there
Watch out
Powers that are too broad get refused as often as ones that are too narrow. Describe the act precisely and give it an end date.
