Power of Attorney

The certification of Thai nationals’ signature in a power of attorney and a letter of consent.

*Non-Thais’ signatures can only be certified in the case of a letter of consent for their child’s Thai passport request. For other purposes, please see the certification of non-Thai nationals’ signature

**The certification of Thai nationals’ signatures must be done only in the presence of the Embassy officer. Applicants must not sign on the power of attorney in advance.

***Each power of attorney can only be presented to one authority. Therefore, please study the details of the authority and the amount of power of attorney that you need to request and present. Please duly prepare the documents that need to be attached with your intended power of attorney and prepare an additional copy of each document for the legalisation application form which needs to be collected by the Embassy.
