Power of Attorney in Thailand: Real Estate, Banking & Company
How to draft and notarize a Power of Attorney in Thailand for real estate transactions, bank account management, and company representation.

A Power of Attorney (POA) allows another person to act on your behalf in Thailand. ILC drafts, translates, and notarizes POAs for real estate transactions, bank account management, company representation, court proceedings, and visa applications.
Common POA scenarios
- Buying or selling a condo without being in Thailand
- Managing a Thai bank account from abroad
- Representing your company at the DBD
- Visa or work-permit renewal by HR
Drafting & notarization
ILC drafts bilingual (Thai-English) POAs aligned with the Thai Civil & Commercial Code and notarizes them in-house. Add MFA and embassy legalization if the POA is used in another country. See our POA service.
Frequently asked questions
Does a POA need to be notarized?
Yes for international use; some Thai authorities (Land Office, banks) accept signed-and-witnessed POAs but notarization is strongly recommended.
Can ILC draft the POA?
Yes. We provide bilingual templates customized to your transaction and notarized by our Notarial Services Attorney.

Documents usually required
- Freshly issued company affidavit and certificate of registration
- Memorandum and articles of association, or the current shareholder list
- Board resolution or power of attorney signed by the authorised director
- ID or passport copies of the authorised signatories
Common reasons a bundle is rejected
- Company affidavits are usually accepted only within a short validity window.
- Director names and job titles must match the registered filing exactly.
- Spell every name exactly as it appears in the passport, across every document in the same bundle.
Prefer not to handle the chain yourself? Send the scans and we run every step for you, from translation to the final endorsement.
What clients typically use this for

An advisor, not only a document processor
Before any work starts, our team assesses how many certification layers your document actually needs, which authorities are involved, and the correct order for the office you will really file with. One step out of order usually means restarting the whole bundle. More than 15 years of cross-border document work means we recognise how each authority rejects files and prevent it up front.
- The certification route is matched to the receiving authority before work begins.
- Rejection risks are checked, from name spelling to document validity windows.
- The filing sequence is planned around the deadline you actually have.
