Notary Public Services in Thailand — Provided by Registered Notarial Services Attorneys

Not in the same sense as the United States or civil-law countries. Thailand has not established a separate notary profession; instead, authority is granted to lawyers who have completed training and registered with the Lawyers Council of Thailand under Royal Patronage — called "Notarial Services Attorneys" (NSA). NSAs are the officials whose certifications are accepted by foreign authorities.

No. Because Thailand is not a party to the 1961 Hague Apostille Convention, documents produced in Thailand must go through chain legalization: certification by an NSA, followed by legalization from the Department of Consular Affairs, Ministry of Foreign Affairs, and finally certification by the destination country's embassy or consulate.

Yes, always, for signature certification, administering oaths, and certifying powers of attorney, because the attorney must verify identity from an original ID document and confirm the signer understands and freely consents. Documents signed in advance cannot be certified after the fact.

No. The certification covers only facts observed directly by the attorney — for example, that this person signed in the attorney's presence, or that this copy matches the original examined. The accuracy and legal effect of the content remains the responsibility of the parties. If you need assurance about content, use a separate contract-review service.

Yes. The attorney can certify a signature on an English or other foreign-language document. If the signer does not understand the language of the document, a translation and an interpreter must be present as a witness to confirm the signer understood before signing. Translation certification is issued as a certificate confirming the translation matches the original, together with the translator's certification.

On-site certification is generally completed the same day once documents are complete. If MFA legalization is required, add roughly 2-3 business days for standard service, and if the destination embassy is also involved, timing depends on that embassy's queue and rules — overall it is typically 3-10 business days.

The certificate states the attorney's name, law-practice license number, and Notarial Services Attorney registration number, all of which can be verified with the Lawyers Council of Thailand under Royal Patronage. The Consular Affairs stage of legalization also serves as a further verification of the attorney's signature and seal.

Yes. We regularly take instructions from overseas law firms, company secretaries, and in-house legal teams, coordinating in English by email, reviewing drafts in advance, scheduling the signer who is present in Thailand, and returning original documents via international courier with tracking.

We provide off-site service within Bangkok and its vicinity, including for signers in hospitals or other restricted locations, subject to advance scheduling and confirmation that the signer is of sound mind and signing voluntarily. For upcountry locations, an attorney can travel by prior appointment.

Fees depend on the type of certification, number of documents, urgency, and the legalization steps required by the destination. Please provide details of your documents and destination country to request a written quote, which will itemize government fees separately from our service fee.

Send us the rejection reason in writing. Our team will determine whether the issue was the certification format, wording, translation, or a missing legalization step, and then correct it or issue a new certification that meets the destination authority's requirements.

The attorney is required to record every certification in a notarial register and retain copies of documents as evidence in accordance with Lawyers Council regulations. All information is subject to the attorney's duty of confidentiality and the firm's personal-data-protection policy, and will only be disclosed to third parties pursuant to a lawful order.
