A Notary Public in Thailand is a Notarial Services Attorney registered with the Lawyers Council of Thailand. They certify signatures, true copies, affidavits, powers of attorney, contracts, and translations for use abroad. For use abroad, check the receiving authority's current requirements for any further legalization. Signature witnessing normally requires the signer to appear with original ID.

Thailand uses Notarial Services Attorneys licensed by the Lawyers Council of Thailand. They perform core functions including signature certification, certified true copy, affidavits, powers of attorney, contracts, translation certification and fact certification.
Fees depend on document type, language, number of signatories, and any onward MFA or embassy steps. Ask our team for a quote via LINE @THAIL or 092-0170000.
Signature certification normally requires the signer to appear with original ID so identity can be verified. Some copy certifications can be assessed from documents sent in advance; we confirm what applies to your case.
Notarization by a registered Notarial Services Attorney is a common first step before MFA or embassy legalization. Each receiving authority sets its own rules, so we check its current checklist before submission.
We have two offices: Bangkok (61 Soi Lat Phrao 95, Wang Thonglang) and our Khon Kaen head office (680/45 Na Mueang Road). Other provinces are served through partner attorneys; ask us which option fits your location.
Timing is assessed based on your documents, the number of sets and any onward legalization. We give you an estimate once we have reviewed your file.
Yes. We can arrange translation and certification of the translation for common language pairs. Tell us the languages involved and we will confirm availability before starting.
We can coordinate translation, notarization and the onward MFA and embassy steps as one managed workflow. Each authority's own requirements and processing still apply.
Bring the unsigned document, your original passport or Thai ID card, and any instructions from the receiving authority. Do not sign in advance — the attorney must witness the signature.
Yes, if the director has signing authority. Bring a recent company affidavit (DBD certificate) showing authorised directors and the signing conditions, plus the company seal if the articles require it.
Do not assume a Thai-issued document can receive an Apostille in Thailand. Check the current status and the receiving authority's required legalization path before preparing the document.
Often yes, but the attorney must understand what is being certified. A translation may be needed so the signer and attorney both know the content. We review the document first.
We decline documents that appear falsified, incomplete, signed under pressure, or where identity cannot be verified. A notary certifies acts such as signatures or copies; it does not guarantee that the content is legally valid.
Yes. Bring the original; the attorney compares it with the copy and certifies it as a true copy. Some universities or authorities require their own certification instead, so check the receiving institution's rules.
Notarization is usually one step in a longer document chain. These pages cover what typically comes before and after it.
Thailand does not have a civil-law notary equivalent to those in France, Germany or Japan. Instead, the Lawyers Council of Thailand licences qualified lawyers as Notarial Services Attorneys (NSA) under regulations issued in 2003 and updated in 2020. NSA notarisations are the accepted equivalent for MFA legalization, foreign embassy authentication, immigration filings, corporate KYC, and international arbitration. iLC's in-house NSA team is licenced across all eight statutory notarial acts: (1) attestation of signatures, (2) certification of true copies, (3) administration of oaths and affirmations, (4) certification of facts, (5) notarial protests for negotiable instruments, (6) authentication of Powers of Attorney, (7) certified translations under notarial cover, and (8) attesting of corporate documents. We handle rush apostille-equivalent chains for time-critical M&A closings and immigration windows.
The workflow below reflects current 2025–2026 practice with the relevant Thai authority and factors in queue seasonality, translation dependencies, and cross-agency handoffs.
Confirm the destination authority to pick the correct notarial format (signature, true copy, oath).
Legal review of the underlying document to catch missing signatures, incorrect party names or governing-law inconsistencies.
Signer attends the notary either in person or via video link where permitted; identity is verified against passport or Thai ID.

For overseas use the certified copy is legalised by the MFA timing is assessed on your documents.
Destination-country embassy stamps the file for full cross-border admissibility.

POA notarisation for buying property in Portugal, UK, USA on behalf of a Thai buyer.

| Option | Pros | Trade-offs |
|---|---|---|
| Signature attestation | Quickest (30 min), lowest fee | Only certifies signature identity, not content |
| True-copy certification | Recognised by most banks and embassies | Original must be presented |
| Notarial cover translation | Combines translation + notary in one file | Longer preparation (48 hours) |
Legally different but functionally equivalent for cross-border use once MFA and embassy chain are completed.
Some acts (signature attestation for certain destinations) permit remote notarisation with additional identity checks.
Yes. Our NSA team drafts and notarises in English, Thai, and dual-language templates.
Yes once combined with MFA + embassy attestation for non-Hague destinations.

For Thai Notarial Services Attorney (Notary Public) — Practice Guide, confirm names, document types, and the receiving authority's current requirements before starting. Timing and fees depend on each case.
Please confirm current requirements with the receiving authority
Thailand does not have civil-law notaries. Signatures and copies for use abroad are usually certified by a lawyer registered with the Lawyers Council of Thailand as a Notarial Services Attorney. The certificate confirms what the lawyer personally witnessed — who signed, and that a copy matches the original shown — not that the content is legally correct. It also does not replace legalization by the Department of Consular Affairs or an embassy, so always ask the receiving authority which steps it requires.
Not exactly. In Thailand this role is performed by lawyers registered with the Lawyers Council of Thailand, so powers and formats differ from notaries in some countries. Confirm the receiving authority accepts this form of certification.
Thailand acceded to the Hague Apostille Convention on 30 June 2026, but it only enters into force for Thailand on 28 February 2027 (HCCH); until then, Thai documents are usually legalized by the Department of Consular Affairs and then by the destination country's embassy, as that country requires.
Yes. You must appear with original ID and sign in front of the lawyer. A signature made beforehand cannot be certified as yours.
No. It confirms only what the lawyer witnessed. A legal review of the content is a separate service.

| Aspect | Doing it yourself | With iLC |
|---|---|---|
| Working out which steps apply | You read each authority's rules yourself, and usually learn a step was missing only after the bundle is refused. | Our advisers review the documents before work starts and sequence translation, notarisation, MFA, and embassy in one pass. |
| Time spent filing | Repeat trips to each office, queueing and collecting in person. | We file on your behalf; you send scans and receive the finished set by post or courier. |
| Risk that the translation is refused | Agency names, job titles, and the certification wording often do not match what the receiving office accepts. | We use terminology and certificate formats the receiving authority has accepted before, with two-stage proof-reading. |
| If the bundle is rejected | You diagnose the cause and refile yourself, losing a full cycle. | We identify the cause, correct it, and refile without you starting over, with progress reported along the way. |
Before any work starts, our team assesses how many certification layers your document actually needs, which authorities are involved, and the correct order for the office you will really file with. One step out of order usually means restarting the whole bundle. More than 15 years of cross-border document work means we recognise how each authority rejects files and prevent it up front.
