Six Notarial Services Attorneys in Sukhumvit, Bangkok review the receiving authority’s requirements before not
Licensed Thai notarial attorneys · Sukhumvit, Bangkok
Six Notarial Services Attorneys in Sukhumvit, Bangkok review the receiving authority’s requirements before notarizing affidavits, Powers of Attorney, true copies, and corporate documents. Timeline confirmed after review may be available for straightforward documents after the original, signer, and destination rules are checked.

Thailand uses Notarial Services Attorneys (not civil-law notaries). These are practicing lawyers licensed by the Lawyers Council of Thailand to perform every function a foreign Notary Public performs: witness signatures, certify true copies, administer oaths, and authenticate corporate documents.
We serve embassies and consulates in Bangkok, multinational HR departments, and individual expats. Documents are notarized in English (or any required language) and can be chained through MFA + your home embassy for use back home.

We coordinate post-notary authentication with many embassies in Bangkok and overseas receiving authorities. Requirements vary by document, destination, and intended use, so the destination checklist is confirmed before submission. Common destinations include the USA, UK, Germany, France, Australia, Japan, China, UAE, Saudi Arabia, Russia, and India.
Hague Apostille (in force for Thailand 28 February 2027) is available for member states. Non-Apostille countries get the traditional MFA + embassy chain.
English-quoted, USD-equivalent available.
Urgent requests are scheduled after document review even when one lawyer is in court. Our 10-year archive lets us re-issue replacement copies if your home country requests verification long after the original notarization.

Is a Notarial Services Attorney equivalent to a US/UK Notary Public?
Yes. The Lawyers Council of Thailand authorizes these attorneys under Regulation 2546 (2003) specifically to perform every notarial act recognized internationally.
Do you offer mobile notary?
Yes — Bangkok metro, including hospitals (for sick witnesses), hotels, and corporate offices. Travel surcharge from ขอใบเสนอราคา.
Can you notarize in a language other than English?
Yes. Our in-house translators cover Thai, English, Mandarin, Japanese, Korean, German, French, Russian, Spanish, and Arabic.
How fast can you turn around an affidavit?
Same-day if you arrive before 14:00 with ID. Document drafting takes an additional a timeline confirmed after review.
Apostille or embassy chain?
Thailand will issue Hague Apostilles from 28 Feb 2027. If your destination country is an Apostille member, single Apostille suffices; otherwise we route through MFA + embassy.
Walk-in or appointment?
Appointment preferred (LINE @thainotarylaw). Walk-ins accepted M–F 09:00–17:00 if attorneys are available.

Short answer: In Thailand the certifying officer is a lawyer registered as a Notarial Services Attorney with the Lawyers Council. The signer must sign in front of that lawyer with original identity documents. The certificate is then authenticated at the Department of Consular Affairs and at the receiving country's embassy where required.
Individuals
Companies
Foreign nationals
1. Confirm the receiver's requirements before printing
Establish which act is needed (signature witnessing, affirmation or certified copy), whether fixed wording applies, and how many authentication layers the receiver expects.
⏱ Confirmed with quotation
2. Assemble documents and book the signing
Complete the set, print the final text and leave the signature block blank, because signing must happen in the attorney's presence.
⏱ 1 working day (estimate)
3. Sign before the attorney and obtain the certificate
The attorney verifies identity, checks the document, records the act in the register, then signs and seals the certificate.
⏱ 1 working day (estimate)
4. Authenticate at the Department of Consular Affairs
Submit the certificate to the Legalization Division so the attorney's signature is authenticated, where the receiver requires that layer.
⏱ 2-5 working days (estimate, excluding agency queues)
5. Embassy authentication and delivery
File with the receiving country's embassy or consulate under its own procedure, then deliver the sealed set without breaking the cross-seal.
⏱ 3-10 working days (estimate, varies by mission)
| Criterion | Do it yourself | Our team handles it |
|---|---|---|
| Checking destination rules | You contact the receiver and mission and interpret the rules | We confirm requirements and draft wording to match before printing |
| Multi-layer processing | You travel and queue at each layer | We run the layers continuously and report status at each one |
| Rejection risk | Frequent, driven by wording format and document age | Screened in advance by a team with more than 15 years in this field |
| Your time commitment | Several working days spread across the chain | Only the signing appointment |
If you would rather not chase agency rules and queues, our team can run the chain from draft review to delivery. Initial consultation is available by phone, LINE or email.
All durations are working-day estimates excluding agency queues, and are not a guarantee of any authority's decision.

Before we start, we read your actual documents and confirm the legalization route matches what the receiving authority asks for. During the work we report progress, and after delivery we still answer questions about how to submit the file.
We prepare documents to the requirements of the receiving authority. Any approval decision remains at that authority's discretion.
Send your documents on LINE for a preliminary review, a recommended legalization route and a written quote.
General guidance, not a case-specific determination. Requirements change with agency notices — confirm with the receiving authority before you act.

Short answer: The most frequent causes are signing before meeting the attorney, expired identity documents, choosing a certificate type the recipient does not accept, and skipping a step in the legalisation chain. Each is fixed by re-executing a correctly drafted certificate before the next certification round starts.
If a second round is not an option, our advisers review the recipient's form, select the correct instrument and map the full chain before you start — send us the documents for a pre-check.
