Director Resolution
Drafted by the company secretary or counsel and signed by all directors who voted in favour. Must reference the meeting minutes (date, place, attendees) and the exact authorised act. Notarised at NSA before legalization.
Affidavit of Director
Two variants. The DBD (Department of Business Development) issues an official certificate listing director names and signature specimens — valid 6 months. Alternatively a notary-prepared affidavit lets directors swear to the same facts immediately — useful when the DBD version is delayed.
Certificate of Incumbency
Used when a Thai parent company needs to evidence ownership of an offshore subsidiary (BVI, Cayman, Singapore). Lists directors, shareholders and registered office. Combine with passport copies of UBO for KYC compliance.
Legalization timeline
NSA notarisation 1 day; MFA legalization 1–3 days; destination embassy 1–7 days. Plan two weeks for full cycle, longer for the Chinese or UAE embassies.
