Notarization Requirements

Thailand does not have a separate “notary public” office. Notarial work is done by notarial services attorneys, who are Thai lawyers registered for this role with the Lawyers Council of Thailand. The attorney confirms who you are, watches you sign and certifies the document for use in Thailand or abroad.

Every person whose signature needs notarizing must be present in person, either at our office or during a mobile visit. We cannot notarize a signature for someone who is not there.

Each signer must show an original, unexpired government ID: a passport for foreign nationals, or a Thai ID card or Thai passport for Thai nationals. The name on the ID must match the name on the document. Copies and photos on your phone are not accepted. See Proof of Identity for Notarization.

Please bring your document unsigned. The attorney has to see you sign, and in some cases you will need to make a declaration first.

You must understand what you are signing and sign it willingly. If the document is in a language you do not read, a translation may be needed first. We can arrange certified translations.

Bring the full document with all pages, and make sure no blanks are left to fill in later. If you do not have a document yet, our team can draft it for you, for example a power of attorney, affidavit or consent letter. Templates are also available on our Downloads page.

If you sign on behalf of a company, also bring documents showing your authority to sign, such as a recent company affidavit or certificate of registration, or a board resolution or power of attorney.

Tell us which country and organization will receive the document. Some authorities require specific wording, witnesses or translations, and many documents used abroad also need legalisation after notarization.

Email us a copy of your document before the appointment at info@notary-public.in.th. We can check it in advance, confirm the fee and keep your appointment short.
