Service we CAN provide
An affidavit is a sworn statement of facts, made voluntarily, and confirmed by the oath or affirmation of the person making it. The Embassy and Consulate assume no responsibility for the veracity of the representations that appear in the affidavit. Only the identity of the individual making the statement is validated.
NOTE: the Embassy and Consulate will not notarize affidavits or perform other notarial services listed in the “Services we CANNOT provide” section above even if it is statement that you yourself wrote and are seeking to have notarized.
Acknowledgement of Signature
An Acknowledgement of signature verifies a particular person signed a given document such as a deed or bill of sale. We can notarize only the signatures of those who are present to sign in front of a Notarizing Officer. If you are signing on behalf of a corporation, LLC, etc., you are required to provide proof that you are authorized to sign on behalf of the organization.
Authentication or Legalization of Royal Thai Government Officials’ Signatures
Authentications certify the official seal, signature and/ or authority of foreign officials who perform an official act with regard to a document that is to be used in the United States. The U.S. Embassy may authenticate documents that bear the seal of the Ministry of Foreign Affairs provided their signature is on file with this office.
A Consular Authentication does not attest to the authenticity of the contents of a document but merely to the seal and signature of the issuing Thai government official.

Power of Attorney
A power of attorney allows you to designate someone to take legal action on your behalf, such as authorizing someone to buy or sell a property in the United States in your name while you are abroad. You can use our blank Power of Attorney or bring your own drafted one. If you are signing on behalf of a corporation, LLC, etc., you are required to provide proof that you are authorized to sign on behalf of the organization.
Only the individual(s) SIGNING the document(s) should schedule an appointment and appear. The American Citizens Services unit has limited appointment availability. Individuals who are not required to sign should not schedule an appointment as it would take the appointment away from another person who may need it. Minor children may accompany a guardian, however, this is not recommended as the waiting area is small and unaccommodating.
If your document requires the presence of witnesses, you must supply these witnesses and each witness MUST have their own scheduled appointment. Witnesses must bring their valid government-issued photo ID. Consular staff CANNOT act as witnesses.
How to make a Notary Appointment
Make an appointment using our ACS Appointment System Website.
Please print, organize and complete the appropriate notary form before your appointment. There are no public printing or copying services at the Embassy and Consulate. If you do not have access to the necessary technology, you may obtain a blank copy of an affidavit in the waiting room on your appointment date. Use of the blank version will lengthen your check-in time.
In order to receive notarial services from the Consular Section you must:
- Understand your document. Consular staff cannot explain the contents to you;
- Complete the document with the appropriate names, places, and dates before you arrive (but do not sign it; you must sign in front of a Notarizing Officer);
- Include all pages, information and accompanying documents;
- Organize all pages in order and the page(s) that requires the notary seal must be clearly flagged on the edge of the document;
- Ensure name of the individual signing the document matches the name on the presented identification (i.e., passport or other government issued ID);
- If you are signing on behalf of a corporation, LLC, etc., you must bring proof that you are authorized to sign on behalf of the organization; e.g. business card and/or articles of incorporation etc.
- If your document requires witnesses, please ensure they each have a separate scheduled appointment and appear with a valid government issued photo ID;
- Do not sign your document until requested to do so by a Consular Officer.
How to prepare for your appointment
On the date of your appointment please bring with you:
- The unsigned, completed, and clearly flagged/organized document(s) you need notarized;
- Your valid government-issued photo ID; (Note: If your document references a specific form of ID you are required to present it at your appointment. A copy of the ID will not be accepted)
- One photocopy of the bio-data page of the government-issued photo ID you will present with your document;
- The appropriate fee of $50 PER NOTARY SEAL, payable in cash (USD or THB) or by credit card;
- Your (and your witnesses) printed appointment confirmation page(s).
Please be prepared to spend at least one-half hour to two hours at the embassy. Wait times are dependent upon the amount of notaries needed by each customer. ACS can notarize multiple documents during one scheduled appointment.
Refusal of Notarial Services
Please be aware that a consular officer may refuse any notary service when:
- The document will be used in transactions that may be prohibited by U.S. law, treaty or foreign law;
