How much does corporate document notarisation cost in Thailand?
Corporate document notarisation in Thailand is quoted per document, from a simple BOJ-5 copy or tax certificate up to an M&A contract signature witness or Ship's Protest. Bulk orders may be eligible for a discount confirmed with staff, and a full legalisation chain (Notary + MFA + Apostille) is quoted separately depending on the destination.

Legal Basis & Cross-Border Compliance
Corporate documents notarised by our attorneys carry the seal and registration number issued under the Lawyers Council of Thailand's Regulation on the Registration of Notarial Services Attorneys B.E. 2546 (2003). This is Thailand's only recognised notarial framework; documents bearing this seal are accepted for legalisation at the Department of Consular Affairs (MFA) and, from 28 February 2027, for Apostille under the 1961 Hague Convention, to which Thailand deposited its instrument of accession on 30 June 2026, with entry into force on 28 Feb 2027 per the HCCH depositary; until then, Thai documents still require MFA + embassy legalisation.
For corporate transactions we routinely coordinate with foreign counsel to ensure documents satisfy destination-jurisdiction requirements: US commercial-registry standards for board resolutions, EU AML directives for UBO disclosures, Japanese Shokuji certifications for M&A closings, and Chinese Consular Legalisation requirements for entities operating without Apostille recognition. We match the notarial certificate language, seal placement, and translator declaration to what the destination authority actually issues acceptance letters against — not just what a template guide suggests.
PDPA compliance: corporate documents often contain director PII (passport numbers, home addresses) and shareholder financial data. Our processing follows the Personal Data Protection Act B.E. 2562 (2019) — documents are handled under a controller-to-controller data-sharing agreement, retention capped at 7 years per CCC §193/30, and all electronic copies encrypted at rest (AES-256) with access logs auditable on request.
Frequently Asked Questions
Can foreign companies without a Thai entity use this service?
Yes. Simply send your documents (POA, board resolution, etc.) for our Thai Notary attorneys to certify — no Thai entity required. We serve foreign companies from many jurisdictions.
Should the Board Resolution be in English or Thai?
Bilingual (Thai/English) in the same document is recommended so it's accepted in both Thailand and abroad without re-translation. Our team drafts and reviews before notarising.
After Thailand joins Hague Apostille, is embassy legalisation still needed?
From 28 Feb 2027 Hague-member destinations (130 contracting parties) accept Apostille without embassy legalisation. Non-member destinations (e.g. China, UAE, Bahrain) still require destination-embassy legalisation.
Is the notary's registration verifiable?
Yes — verifiable directly with the Lawyers Council of Thailand (LCT). All 6 of our attorneys are registered Notarial Services Attorneys; registration numbers appear on every certificate.
Total turnaround for full Chain (Notary → MFA → Embassy)?
Timing depends on the number of documents and the receiving authority (Notary, MFA, embassy, or Apostille from 28 Feb 2027). Ask our staff for a case-specific estimate.
Do you support M&A / Due Diligence with large document volumes?
Yes — Notary attorneys work in parallel. Our attorneys work in parallel to handle large M&A batches efficiently. Bulk-volume discounts are available — ask staff for a quotation.
Are prices higher for foreign companies?
No — same pricing for Thai and foreign companies. Additional charges (e.g. rush work or mobile notary outside Bangkok) are confirmed in a written quotation before work begins.
Do you offer retainer packages for in-house legal teams?
Yes — monthly retainer packages are available for organisations with recurring document flow. Contact staff for scope and a written quotation.
