DBD Director Signature Certification for Corporate Filings
We provide official certification of director signatures for submission to the Department of Business Development (DBD) for various corporate transactions. This service ensures legal compliance for company changes such as director appointments, capital increases, or amendments to company articles, and facilitates submissions for foreign-resident directors.
Why is signature certification required for DBD submissions?
The Department of Business Development (DBD) requires signature certification for certain types of documents, especially for foreign-resident directors or significant company changes. This ensures the authenticity and identity of the signatory in compliance with legal regulations.
Can signatures of directors residing abroad be certified?
Yes! Our Notarial Services Attorneys can certify signatures of directors residing abroad through digital identity verification and signing via video call, in accordance with the Lawyers Council of Thailand Regulation B.E. 2546, ensuring legal validity.
Which types of DBD documents does this service cover?
This service covers signature certification for various documents submitted to the DBD, including applications for company registration (BoJ.1), meeting minutes, amendment registration forms (BoJ.5), notices of change of office or directors (HorSor.1), as well as documents related to capital increases/decreases, MOA/AOA amendments, and filings under the Foreign Business Act.
Why company registrations get rejected — and how to fix it
Short answer: Registrars refuse names that clash or breach naming rules, objectives that do not cover the real business, foreign shareholder powers of attorney without a complete certification chain, and incomplete office-address evidence.

We design the shareholding, objectives and foreign-document chain around the licences you will need next — advice first, filing second.
Durations are working-day estimates excluding agency queues, and are not a guarantee of any authority's decision.
Where do I start if I am unsure which certification I need?
Start with three questions: which authority will receive the document, in which country, and by what date. Those answers determine the authentication route, the translation language and the full sequence.
Why are fees not published on the site?
Scope varies widely with document count, language and the consular steps involved, so we quote against the actual work and confirm details by phone, LINE or email before starting.
Do you serve clients outside Bangkok?
Yes — we serve clients nationwide and overseas, receiving documents by post or courier and scheduling signing appointments when in-person attendance is required.
How is personal data in my documents handled?
Documents are used only for the purpose you state, retained for the period professional duties and data-protection law require, and not disclosed to third parties without consent.
