Full 8 categories × 25 subservices by licensed Notarial Services Attorneys — for foreigners, Thai businesses, and law-firm referrals.
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. Documents leaving Thailand usually continue to the Ministry of Foreign Affairs for an apostille, or to the destination embassy when the receiving country is outside the Hague Convention. Signers must appear in person with valid ID.

Thailand uses Notarial Services Attorneys licensed by the Lawyers Council of Thailand. They perform 8 core functions including signature certification, certified true copy, affidavits, POA, contracts, translation certification, fact certification, and instrument protest.
Fees depend on document type, language pair, number of signatories, and whether onward MFA or embassy steps are needed. Government fees are charged separately at the published official rate, and the full breakdown is confirmed before work starts.
Signature certification requires personal appearance. Certified true copies can sometimes be processed remotely with scanned originals.
Notarization by a registered Notarial Services Attorney is the standard first step before MFA legalization or apostille. Each embassy sets its own document rules, so we check the receiving authority's current checklist before submission.
Nationwide. Main offices in Bangkok, Khon Kaen, Udon Thani, and Nong Khai, plus partner attorneys in Phuket, Chiang Mai, Pattaya, Hua Hin, and major industrial areas.
Most documents complete same-day. Multi-document or rush orders quoted individually.
Yes — bilingual attorneys plus Chinese, Japanese, Korean, German, French, and Arabic translators on staff.
Yes — end-to-end from translation through embassy legalization. Single managed workflow.
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.
Notary applies the stamp, records the act in the notarial register, and issues an original certificate.
For overseas use the certified copy is legalised by the MFA within 2 working days.
Destination-country embassy stamps the file for full cross-border admissibility.
The checklist below covers standard files. Complex or corporate matters can add supplementary certificates, board resolutions, or notarised affidavits; ILC brief these during the intake call.
Real-world scenarios where clients rely on this service every month, spanning individual, family, and corporate mandates.
Notarisation of share transfer instruments for foreign shareholder registers.
POA notarisation for buying property in Portugal, UK, USA on behalf of a Thai buyer.

Three delivery paths are usually available. We select the option that balances cost, deadline pressure, and destination-authority preferences.

|---|---|---|
| Signature attestation | Quickest (30 min), lowest fee | Only certifies signature identity, not content |

| 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.
“The Thai Notarial Services Attorney (Notary Public) — Practice Guide files we see most often are ones the applicant filed themselves and got rejected for an outdated template or a passport-name mismatch — that's why we audit every document before touching translation.”
| Service tier | Fee range |

A corporate client (name withheld) needed Thai Notarial Services Attorney (Notary Public) — Practice Guide on a tight embassy deadline. ILC closed the matter in four business days without a re-file, saving the client roughly two weeks versus a DIY route.
Notary Public is one of the pillar services delivered by our firm — a Bangkok legal-language practice operating since 2004 with in-house certified translators, Lawyers Council of Thailand notarial services attorneys, Ministry of Justice court-listed translators, and licensed visa consultants working under one roof. Every notarial services matter is scoped by a senior specialist on LINE Official @NAATI or by email at ilc@thainotary.co.th before any file moves.
The workflow starts with a document audit: issuer, issue date, spelling against the client's passport, and any expiry rules of the destination authority. This eliminates the single most common cause of rejection at MFA Chaeng Watthana and at embassies in Bangkok — a small mismatch or an outdated template — before a translator ever opens the file.
The service routinely supports six client profiles: individual foreign nationals arriving for work, study, retirement, marriage, or LTR/Smart investor visas; Thai citizens travelling abroad and needing documents recognised in the US, UK, Australia, Canada, Schengen area, Japan, South Korea, China, Singapore, UAE, Saudi Arabia, or India; HR departments of multinationals handling Non-B and BOI work permits; law firms handling M&A, IP portfolios, or cross-border litigation; educational institutions preparing credential packs for foreign universities; and embassies or international organisations on framework contracts.
We serve all 77 provinces of Thailand via nationwide courier: next-day pickup from Bangkok metro and 1–3 day pickup from Chiang Mai, Chiang Rai, Khon Kaen, Udon Thani, Nakhon Ratchasima, Rayong, Chonburi, Phuket, Krabi, Songkhla, and Hat Yai. Overseas clients receive the same service remotely — originals arrive by DHL or FedEx, we execute the workflow, and the pack ships back to more than 40 countries with tracking.
Every deliverable is executed under ISO 17100-aligned quality principles: mandatory bilingual review by a second credentialed translator, controlled terminology glossaries for legal and technical vocabulary, and a signed statement of accuracy carrying the translator's credentials (ATA, NAATI, MoJ, CIOL, or destination-country registry).
Reach ILC on LINE Official @NAATI, email ilc@thainotary.co.th, or phone 080-5578887. Office hours are Monday to Sunday, 08:30 to 20:00 Bangkok time. A specialist responds to first-contact messages within one business hour on weekdays and within four hours on weekends and public holidays with a written price, realistic timeline, and a required-documents checklist tailored to your destination country. There is no charge for the initial consultation, and no obligation to proceed after receiving the quote — ILCearns repeat business by delivering the first notarial services matter cleanly and on time, not by locking clients into open-ended retainers.
