Notarial Services Attorney
Thailand has no stand-alone "Notary Public" profession like the United States or the United Kingdom. Certifying signatures and documents for use abroad must be carried out by a "Notarial Services Attorney" (NSA) who has completed the required training and is registered with the Lawyers Council of Thailand under Royal Patronage. Our firm has NSAs on staff who provide bilingual document certification and coordinate end-to-end legalization with the Department of Consular Affairs, Ministry of Foreign Affairs, and destination embassies/consulates.
Our Team
Foreign authorities can verify the registration status of the signing attorney using the license and registration numbers shown on the certificate. Every certificate issued by our firm is signed only by an attorney who currently holds a valid law license and is registered as a Notarial Services Attorney.

Infographic · Service overview
The diagram below sets out the full certification chain, from verifying the signer to the seal of the destination embassy, together with the four service groups this office handles.
Original passport or Thai ID is inspected and the signer's intent confirmed in the attorney's presence.
The signature is executed in front of a Notarial Services Attorney registered with the Lawyers Council of Thailand.
A notarial certificate is issued, numbered, sealed, and entered in the office register.
The attorney's signature is legalised by the Legalisation Division, Department of Consular Affairs.
The embassy or consulate completes the chain — Thailand is not a party to the Apostille Convention.
Signings are arranged nationwide: an attorney registered with the Lawyers Council of Thailand may certify anywhere in the Kingdom, not only in the province where the office sits. Legalisation, by contrast, runs through a single national office in Bangkok before the file reaches the destination mission.
Street-level maps for both offices are further down this page, under Offices & maps.
Legal Framework
The authority to certify signatures and documents in Thailand derives from the Lawyers Council of Thailand's regulations on the registration of Notarial Services Attorneys, issued under the Lawyers Act B.E. 2528 (1985). Only a lawyer who currently holds a valid license to practice law, has completed the Council's training course, and holds a registration certificate that must be periodically renewed may perform these certifications. Foreign authorities should verify the signing attorney's registration number before accepting a document.
System Comparison
Foreign companies and authorities usually expect the certificate format used in their own jurisdiction. Understanding the differences from the outset reduces the risk of a document being rejected. The table below summarises the questions we are asked most often.
| Aspect | Notary Public systems abroad | Thailand |
|---|---|---|
| Who may certify | A commissioned Notary Public, or a civil-law notary | A Notarial Services Attorney registered with the Lawyers Council of Thailand under Royal Patronage |
| Source of authority | Dedicated notary statutes of each state or country | The Lawyers Council regulation on the registration of attorneys performing notarial services, issued under the Lawyers Act B.E. 2528 (1985) |
| Identifying the signatory | Personal appearance before the notary (some jurisdictions permit remote appearance) | The signatory must always appear in person before the attorney with original identification documents |
| Seal format | A notarial seal in the form prescribed by local law | The attorney's signature, seal and notarial registration number on a certificate attached to the document |
| Downstream certification | In Hague Apostille member states, a single Apostille is sufficient | Thailand is not a party to the Apostille Convention, so documents continue to the Department of Consular Affairs, Ministry of Foreign Affairs, and then to the destination embassy or consulate |
| Verification after the fact | Checking the notary register kept by the commissioning authority | Checking the attorney's lawyer licence number and notarial registration number, together with the firm's notarial register entry |
Certification Types
Each certification type has a different format and identity-verification requirement. Our attorneys choose the format that matches the destination authority's requirements.
Attorney witnesses your signature in person and issues a sealed Notary Public certificate.
Attorney certifies the copy matches the original — accepted overseas in lieu of the original.
Cross-border POAs need Notary + MFA + destination consulate — end-to-end service.
Attorney certifies the translation matches the original — accepted worldwide.
Attorney administers the oath and witnesses your sworn statement — accepted by courts and embassies worldwide.
Certify company certificates, board minutes, resolutions, and foreign-director signatures.
Thailand is not in the Apostille system — documents must chain MFA + destination consulate. Full end-to-end service.
Attorney travels to your hotel, hospital, or airport 7 days a week; 30-min express.
The attorney records and certifies facts personally observed — document status, existence of assets, or events witnessed in person.
The attorney certifies having sighted the original on a specific date — for cases where the original cannot leave Thailand.
Certified board and shareholder resolutions with signing-authority verification for foreign banks and registries.
Notarization of Certificates of Free Sale and Origin, commercial invoices, packing lists, and distributor appointments.
Notarization of applications, enrolment certificates, guardian consents, and financial-support documents.
For overseas pensioners and KYC processes requiring in-person verification before a Notarial Services Attorney.
Drafting and certification of sworn written statements for foreign courts, counsel, and arbitral tribunals.
A rule-accurate explanation of what can be done online, what still requires physical presence, and which alternatives destinations accept.
Full Scope of Service
The scope below covers the certification work a Notarial Services Attorney is empowered to perform under Lawyers Council regulations, plus downstream translation and legalization work. If your matter is not listed, our team will review the destination authority's requirements and advise the correct approach before starting.
The signer must always appear personally before the Notarial Services Attorney with an original ID document
The original must be presented for comparison — the attorney will not certify from an image file alone
Used alongside MFA legalization when the destination requires an English-language version
The attorney certifies that the deponent swore or affirmed in their presence — not the truth of the content
Handles high-volume work for in-house legal teams and overseas law firms
The certification format depends on the requirements of the receiving authority
Languages & Translation
Documents used abroad usually require an attached translation, and receiving authorities prescribe different translation formats. We confirm the format required by the destination before work begins.
We communicate and prepare documents mainly in Thai and English. Chinese and Japanese matters are handled through translators or interpreters engaged by the firm, and the attorney always confirms that the signatory understands the content before signing.
Where the original is in Thai, an English translation is attached and certified in the format the destination requires — for example certification of the translator's signature, or a statement as to the accuracy of the translation.
An interpreter must explain the full text in front of the attorney, and the use of an interpreter is recorded in the certificate. If the attorney is not satisfied that the signatory understands the content, the certification will not proceed.
The Department of Consular Affairs applies its own language and translation-format requirements. Confirm the current conditions with the department before filing, as they may change.

Certified passport copy with English notarial certificate for banking, visas, and offshore incorporation.
Notarize diplomas and transcripts with certified translations for jobs, further study, and credential evaluation abroad.

Real-World Use Cases
Certification isn't one-size-fits-all — each destination authority sets its own wording and process. The examples below are the matters companies and foreign agencies most often instruct us on.
Foreign companies
A power of attorney authorizing a Thai representative to register with the Department of Business Development, board resolutions approving the investment, and a certificate of good standing for the parent company all need the authorized signatory's signature certified and then legalized before Thai authorities will accept them.
Foreigners in Thailand
Affidavits confirming income or marital status, certified passport copies, academic transcripts, and consent letters for a minor's travel are documents that embassies and foreign universities almost always require to be certified by an attorney first.
Thais living abroad
Selling land, transferring a condominium, closing a bank account, receiving an inheritance, or litigating by proxy all require a power of attorney signed before a Notarial Services Attorney, together with original ID documents and a certified copy of the grantor's ID card.
Family matters
Certificates of single status, translations of marriage/divorce registrations, parental consent letters, and custody certifications require translation certification and legalization according to the requirements of the destination registrar.
International trade
Distribution agreements, certificates of origin, distributor appointment letters, and tender documents required by foreign government agencies need the director's signature and company seal certified.
IP and litigation matters
Trademark-ownership certifications, witness statements, and statutory declarations that must be sworn before an attorney, using the exact oath wording required by the destination.
Ways We Work
We review your draft by email in advance and schedule the signer to attend. On-site time is roughly 20-40 minutes per document set, and original documents can be taken away immediately if no further legalization is required.
An attorney travels to your office, a hospital, or a government office — ideal when there are multiple signers or a signer who cannot travel. Requires advance scheduling and confirmation of the signer list with ID documents.
We take on bundled instructions, coordinate in English by email, assign a single point of contact per project, report status at every step, and courier original documents back overseas with a tracking number.
We file and collect documents on your behalf at the Nationality and Legalization Division, Department of Consular Affairs, and forward them to the destination embassy or consulate, arranging translators for whatever language the destination requires.
Our Process
Tell us the country, receiving authority, and purpose of the document, and send the draft file so the attorney can determine the correct certification type and whether the destination requires further legalization.
The attorney checks the form, bilingual wording, and signature blocks, and lets you know which ID documents and corporate certificates you'll need to bring.
The signer must appear in person with an original ID card or passport. Company directors must bring a current company affidavit. If the signer does not understand the language of the document, an interpreter is arranged to witness the signing.
The attorney signs, applies the notarial seal, issues an English-language certificate attached to the original, and records the certification number, date/time, and signer details in the notarial register.
If required, we file the legalization request with the Department of Consular Affairs (Legalization Division) and forward the document to the destination embassy or consulate for further certification, with status updates at every step.
Process Timeline
The timing below reflects actual practice. Steps handled by government agencies and embassies depend on those agencies' own rules and queues, which can change.
| Step | Estimated Time | Notes |
|---|---|---|
| Draft review and recommended certification format | Within the same business day | Send photos of the documents and specify the destination agency for a complete review |
| Signing appointment at our office and issuing the certification | Approximately 30-60 minutes per document set | Depends on the number of documents and whether an interpreter is needed |
| Preparing translations and translator certifications | 1-3 business days | Depends on volume and terminology complexity |
| MFA Consular Affairs legalization | Per Consular Affairs' queue and rules | Both standard and express services are available; timing and fees follow the agency's published notices |
| Filing with the destination embassy or consulate | Per each embassy's own rules | Some require advance appointments and require the document owner to be the one who files |
For urgent matters, our team prioritizes your signing and filing, but we will not promise timing that is outside our control, such as the Consular Affairs or destination-embassy queue, so you can plan accurately.
Document Legalization
Thailand is not a party to the Convention Abolishing the Requirement of Legalisation for Foreign Public Documents (the 1961 Hague Apostille Convention). Documents from Thailand therefore cannot use an Apostille and must go through the following chain certification instead:
Step 1
Certifies a signature, copy, or translation and issues an English-language certificate
Step 2
Certifies the signature and seal of the attorney or certified translator. Standard service usually takes about 2-3 business days, with same-day express service available for some document types
Step 3
Certifies the signature of the Consular Affairs officer as a further layer. Timing and requirements depend on each embassy's own rules; some require advance appointments and an official-language translation of that country
Check the latest rules and fees with the Department of Consular Affairs, Ministry of Foreign Affairs consular.mfa.go.th and the Lawyers Council of Thailand under Royal Patronage lawyerscouncil.or.th as timing and requirements depend on each agency and can change.
Destination Countries
| Region / Country | Preparation Notes |
|---|---|
| United States, Canada | Generally accepts an attorney's English-language certification with Consular Affairs legalization. Some states or agencies require additional embassy certification — check the specific agency's form before signing. |
| United Kingdom, Australia, New Zealand | Uses the Statutory Declaration or Affidavit format with specific oath wording. Many Australian agencies require translation by a NAATI-certified translator — check the destination agency's requirements first. |
| Japan, South Korea, Taiwan | Generally requires Consular Affairs legalization followed by certification at the embassy or the relevant economic and cultural representative office in Thailand. Some agencies require translation into that country's official language. |
| China | Chinese agencies generally require a Chinese translation and certification from the Embassy of the People's Republic of China in Thailand. Exact wording and number of copies vary by province and transaction type. |
| European Union | Requirements vary by country. Some require a sworn translator registered with that country's courts, which must be handled in the destination country — we will flag this at the assessment stage if it applies to your case. |
| Middle East and Gulf states | Generally requires Consular Affairs legalization followed by certification at the destination country's embassy. Many require an Arabic translation and charge a separate embassy fee. |
The information above reflects general practice as of August 2026. Requirements at each embassy and destination agency can change at any time — please confirm the latest requirements with the receiving authority before proceeding.
Before Your Appointment
Reduce Your Risk
Before your appointment, our team checks these items every time, as they are the most common reasons Consular Affairs or a destination authority rejects a document.
Names on the document must match the passport or ID card exactly, letter for letter. If you have changed your name, attach evidence of the name change together with a translation.
Signature certification is only possible when the signer signs in the attorney's presence. A pre-signed document must be re-signed, or a different certification format used instead.
Company affidavits, house registrations, and certificates of single status are often accepted by destination agencies only if issued within the last 3-6 months — check the document's age before scheduling.
Seals, signatures, footnotes, and marginal notes must all be translated or noted in the translation — otherwise Consular Affairs or the embassy may reject the document.
Certifying a true copy requires the original to be presented to the attorney. A photograph or scanned file cannot be certified on its own.
Some agencies require both Consular Affairs legalization and embassy certification. Skipping either step causes the document to be rejected — always confirm the exact destination authority up front.
Practice Standards
Confidentiality & Verification
Documents sent for certification frequently contain personal data and sensitive commercial information, so the firm applies clear rules on storage and disclosure.
Client information is subject to the attorney's professional duty of confidentiality and is processed under the Personal Data Protection Act B.E. 2562 (2019). It is disclosed to third parties only with consent or where required by law.
Document copies and notarial register entries are retained for later verification, stored separately from litigation files, with access limited to the personnel responsible for the matter.
Drafts can be sent for review in advance by email or another agreed channel. We recommend redacting information that is not needed for the review, such as bank account numbers, before sending.
A receiving authority can check the lawyer licence number and notarial registration number shown on the certificate, ask the Lawyers Council of Thailand under Royal Patronage to confirm the registration status, and contact the firm to confirm the certificate number in the notarial register.

Frequently Asked Questions
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, then legalization at the Department of Consular Affairs (Ministry of Foreign Affairs), and last the endorsement of the embassy or consulate that will receive the file.
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.
