DBD Director's Signature Certification

Primary users are directors of limited and public-limited companies — both foreigners and Thai nationals who cannot personally appear at the DBD registrar — who use this notarial certification in lieu of in-person signing before the registrar. It is also used when directors live abroad and engage a Thai legal team to file on their behalf. The attorney certifies the director's signature on DBD-prescribed forms such as Bor.Or.Jor.1, 3, 4, 5, 6 and various amendment applications.

Special cases are also supported: directors who recently relocated abroad, directors who travel frequently with limited time, or foreign companies registered in Thailand whose authorized director does not reside in Bangkok. In every case our team can host the appointment at our office, travel to the client, or meet at a mall convenient to the client's location.

DBD has very specific requirements that, if missed, cause immediate rejection: (1) the certifying attorney must display the attorney registration number and Notarial Services Attorney registration number; (2) the Notarial Services Attorney license number must be stated; (3) the attorney seal must be affixed at the prescribed location; (4) the certification wording must state ‘signed in my presence’ along with date, time, and place; (5) for foreign directors, a passport copy certified by the same attorney must be attached.

Additionally, some provincial DBD offices may request extra evidence such as a company affidavit no older than 30 days or a business license. We verify each registrar office's local rules in advance and prepare every supporting paper in a single appointment, eliminating the risk of repeat visits.

Step 1: Send draft Bor.Or.Jor. forms or amendment applications for review. Our team checks the language, signature placement, and attachments. Step 2: Book an in-office appointment, or our attorney travels to the director. The meeting takes about 30–45 minutes per set. Step 3: The attorney verifies the director's passport/Thai ID and compares the on-the-day signature to the specimen on file at DBD to ensure it matches the registered signature.

Step 4: The director signs in front of the attorney; the attorney signs, applies the Notary seal, logs the act in the Notarial Register, and issues a certification number. Step 5: The client (or their counsel) files the documents with DBD — or we can handle the entire filing process end to end.

A Japanese company in Bangkok needed to add a new Japanese director and remove a departing one — the resigning director was in Tokyo and could not fly back to sign at DBD. Our team coordinated for the Tokyo director to certify his signature at the Royal Thai Embassy in Tokyo, while the in-country director used our service in Bangkok; we then completed the DBD amendment filing end to end.

A SET-listed public company needed to amend its Memorandum of Association to broaden its objects — because the two authorized directors had tight schedules, our attorneys travelled to the head office during the lunch break, notarized signatures on 12 document sets within 90 minutes, and coordinated with the company secretary's office on all attachments.
