Most notarizations in Thailand take only a few minutes. You do need to arrive with the right documents. A missing passport or a document you have already signed can mean a second appointment, which is a problem when you’re working to a deadline. This checklist covers what a notarial services attorney in Thailand will need from you for a general notarization.

Quick checklist

  1. Original, valid photo ID for every signer
  2. The complete document, unsigned
  3. Every signer present in person
  4. Details of the country and organization that will receive the document

1. Original, valid identification

The attorney must confirm who you are before notarizing your signature.

  • Foreign nationals: your original, valid passport.
  • Thai nationals: your Thai ID card or Thai passport.

Photocopies, scans and photos on your phone aren’t accepted. If the name on your document is different from the name on your ID, for example after marriage, bring the certificate that links the two names. For full details, see Proof of Identity for Notarization in Thailand.

2. The complete document, unsigned

Bring the whole document, with all pages and attachments. Fill in everything except your signature and the date. The attorney has to see you sign. A document that is already signed usually has to be signed again in front of the attorney.

Common documents we notarize include:

  • powers of attorney
  • affidavits and statutory declarations
  • consent letters, for example for a child travelling abroad
  • company documents, such as board resolutions
  • certified true copies of passports, degrees and certificates

Don’t have a document yet? Our lawyers can draft it for you, or you can start from one of the free templates on our Downloads page.

3. Every signer, in person

Everyone whose signature needs to be notarized must attend with their own original ID, either at our office or during a mobile notary visit. If you are signing for a company, bring documents showing that you are authorized to sign, such as a company affidavit or a board resolution.

4. A language the attorney can understand

We can help in English and Thai. If your document is in another language, a translation is usually needed first so that the attorney understands what is being signed. We can arrange a certified translation.

5. Where the document is going

Tell us which country and organization will receive the document. Some authorities have their own requirements for wording, witnesses or translations. Many documents used abroad also need legalisation after notarization. Thailand is joining the Hague Apostille Convention, which is scheduled to take effect for Thailand on 28 February 2027. Until then, the current legalisation process still applies. See Apostille Requirements.
