Corporate documents we certify
Company Affidavit, list of shareholders (BOJ.5), Memorandum of Association, Articles of Association, Board Resolutions, Shareholders’ Resolutions, director powers of attorney, certifications of company seal, and all forms of international business contracts.

Why corporate certification must be rigorous
Corporate documents carry binding legal and financial weight. The Notary verifies (1) the entity's status with the DBD, (2) authorized directors per the company affidavit, (3) signing conditions (sole, joint, with seal), (4) the original ID of the signing director, and (5) that the board/shareholders’ resolution was genuinely passed.
Process for corporate clients
1) Send drafts plus a recent company affidavit (≤30 days old) for our pre-review.
2) Bring authorized directors to our office, or we visit yours.
3) Attorney verifies director ID + original company affidavit.
4) Director signs and seals in front of the attorney.
5) Attorney applies Notary seal, logs the act, and forwards to MFA + embassy if requested.

FAQ
Frequently asked questions
Is a Thai Notary Public different from a foreign Notary Public?
In Thailand, the Notary Public role is performed by ‘Notarial Services Attorneys’ licensed by the Lawyers Council of Thailand. Their certifications are valid abroad once further attested by the MFA Department of Consular Affairs and the destination embassy.
How long does the process take?
Typically 30–60 minutes per document set when booked in advance. MFA legalization adds 1–3 working days.
Can the notarized document be used abroad immediately?
Most overseas use requires three steps: (1) Notary by attorney (2) MFA legalization (3) Destination embassy attestation. We handle all three.
What is the starting fee, and are there additional costs?
Notary by attorney starts at THB 1,500 per document set. MFA legalization adds THB 200–800 government fee and THB 2,500–5,000 service fee per applicant for filing.
How can clients outside Bangkok or abroad use this service?
We deliver nationwide and worldwide. Domestic clients can ship documents by post; international clients can use international courier, with video-verified identity where permitted by law.

Service-specific FAQ
Why must the DBD certificate be < 30 days old?
Embassies and foreign banks need confirmation that company data (directors, address, capital) is current. Over 30 days is often rejected on the spot.
Is the company seal required?
Yes if registered as part of company by-laws with DBD. If not registered, state it clearly in the resolution and certificate.
Director is overseas — can't fly in?
Sign before a Notary in the director's country, then send back for Thai MFA legalisation — we coordinate the foreign Notary.
Valid for BOI/IEAT filings?
Yes — notarised documents from a licensed attorney are accepted by BOI, IEAT, EEC, SEC and DBD.
Since when is Apostille available for corporate docs?
from 28 Feb 2027 — Thailand acceded to the Hague Apostille Convention, replacing embassy legalisation for 126 contracting states.
Department of Business Development (DBD), Ministry of Commerce — Corporate filings at DBD require director signatures certified by a licensed attorney with chamber seal. [ref]
Lawyers Council of Thailand — Notarial Services Attorney licence issued by the Lawyers Council of Thailand under Royal Patronage. [ref]
HCCH — Hague Conference on Private International Law — Thailand acceded to the Apostille Convention effective from 28 Feb 2027, removing chain authentication for 126 contracting states. [ref]
Supplemental Q&A from the 2026 SEO brief (this service)
What do I need for Power-of-Attorney (POA) notarization?
Bring (1) an UNSIGNED draft POA — you must sign in front of the attorney; (2) original passport or Thai ID; (3) attorney-in-fact details; (4) referenced supporting documents (land title, company affidavit). English POAs need a Thai translation if used in Thailand.
Does a foreigner's Will in Thailand need Notary certification?
A Will executed in Thailand under Civil Code §§1655-1672 needs only two witnesses — Notary is not required. But if the Will must be used abroad (e.g. to administer estate in the home country), we recommend Notary + MFA + embassy legalization for smoother acceptance.
How is a Certificate of Single Status notarized?
Thais: obtain from your district office → certified translation → MFA → foreign spouse's embassy. Foreigners: sign an Affidavit of Single Status before a Thai attorney or your embassy → MFA → present at Thai district office to marry.
What corporate documents are needed to open an account or register abroad?
Standard pack: (1) DBD company affidavit ≤30 days, (2) BOJ 5 shareholder list, (3) MOA, (4) meeting minutes authorising the transaction, (5) POA to the overseas signer, (6) directors' passports. All notarized → MFA → destination embassy (or Apostille).
What should an expat in Thailand bring for notarization?
(1) Original passport + current-visa page copy; (2) proof of Thai address (lease or utility bill); (3) original documents to notarize; (4) certified translation first if the document is not in English/Thai; (5) tell us the destination country so we can advise the correct chain (Apostille vs. embassy).
