Is a Thai Notarial Services Attorney equivalent to a notary public?

For most destinations, yes. Thailand does not have a civil-law notary; instead the Lawyers Council of Thailand registers lawyers who have completed notarial training to certify signatures, copies and statutory declarations. The attorney's registration number appears on the certificate so the receiving authority can verify it.

What do I have to bring to a notarial appointment?

Bring the unsigned document, your passport or Thai ID card, and any supporting evidence the destination asks for, such as a company registration extract for corporate signings. Do not sign the document in advance: the attorney must witness the signature for the certificate to be valid.

Can a notarised Thai document be used abroad immediately?

It depends on the receiving authority. Some universities and private companies accept the notarial certificate alone. Government bodies, courts and immigration authorities usually require further legalisation through the Department of Consular Affairs and the destination embassy, or an Apostille once the Convention is in force for Thailand.

Notary Public Certification: illustrative case examples and how we handle them

250 realistic notary public certification situations with the approach our Bangkok advisory team takes and the outcome clients can expect — showing page 1 of 10.

Transparency note: these are illustrative composites drawn from recurring matter types, not individual client testimonials and not a guarantee of results. Every outcome depends on the facts and on the discretion of the authority involved.

Documents you need

Original passport or Thai ID card of every signatory
The unsigned original document to be notarised
Any certificate wording prescribed by the receiving party
Company affidavit and seal when signing for a legal entity
Power of attorney if the signatory cannot attend in person
Written instruction from the receiving party on the required certification type

Step-by-step process

Confirm with the receiving party which notarial certificate is required (true copy, signature, or affidavit)
Send a scan for pre-check so names, spelling and dates match the passport exactly
Book an appointment to sign in the presence of the notarial attorney
Sign in person and present original identification
Receive the document with the certificate, seal and register entry number
If it will be used abroad, continue to MFA legalisation and embassy attestation as required

Common pitfalls

Signing before the appointment — the document must then be reprinted
Even a one-letter mismatch with the passport spelling
Presenting a copy where the receiving party requires the original
Assuming Thai notarisation equals an apostille — they are separate steps
Not allowing time for the follow-on MFA or embassy steps

An advisory team, not just a filing service

We do not simply process paperwork — we advise throughout the case. With more than 15 years of experience we review your documents before anything is filed, flag where rejection risk sits, and sequence the full chain end to end. If you would rather not run the process yourself, send the documents for a no-obligation review first.
