Legal Basis of Signature Authentication
Performed by an attorney registered as a Notarial Services Attorney with the Lawyers Council of Thailand under the regulation on registration of attorneys for signature and document certification.
In Thailand, "Notary Public" is not a government office (as in civil-law countries such as Germany or France) — it is a licensed attorney who has completed the Notarial Services Attorney course. Licences are renewed periodically and can be verified before each engagement.
Documents certified by a Thai Notary carry significantly more legal weight abroad than uncertified documents, because the destination authority treats them as having passed authority verification by a recognised certifier under Thai law.
