Trademark POA Certification in Thailand
Foreign trademark owners usually appoint a Thai agent to file with the Department of Intellectual Property. A POA signed outside Thailand is generally signed before a notary and certified as the Department requires; check its current document list before signing.
Certification scope and key checks
State the applicant, the agent and the scope — filing, amendments, responding to office actions, assignment — clearly.
For a company, the signatory must have authority under its home registry; proof of directorship may be required.
A notary certifies identity and signature, not whether the mark will register.
Documents to prepare
- Draft POA stating the scope
- Signatory's passport or ID
- Proof of signing authority (companies)
- Mark details or application numbers, if any
Procedure for this document
- Check the Department's current requirements
- Sign before a notary
- Complete any further certification the recipient requires
- Translate into Thai and send the original to the agent
Overseas use: confirm the recipient’s route
Notarization is not required for every public record, and some uses need no onward legalisation. Confirm whether the recipient needs an original, copy, translation or specific certification before arranging MFA and embassy steps where applicable.
Thailand deposited its accession on 30 June 2026. The Apostille Convention is scheduled to enter into force for Thailand on 28 February 2027. Do not assume Thai Apostilles are available before then. Even after entry into force, document scope and treaty relations with the destination must be checked.
Questions before booking
- Can a scanned copy be filed?
- It depends on current Department practice; sometimes a copy is filed first with the original to follow. Check before filing.
- Does a notary guarantee registration?
- No. Examination is the Registrar's decision.
- Can one POA cover several applications?
- Yes if the scope covers them, but confirm the Department accepts that form.
- Are MFA and embassy legalisation always needed?
- No. Ask the recipient to confirm the certification, language and onward steps. Notarization, translation and legalisation are distinct; do not perform every step automatically.
- How are fees and timing assessed?
- After reviewing the form, copies, signers, language and onward steps, we provide a quote and indicative schedule before work. Authority queues and outcomes are not guaranteed.
- What should I send before booking?
- Send the record type, destination country, receiving authority and its checklist through a direct contact channel. Redact personal information unnecessary for the initial enquiry.
