Can a director also serve as the company secretary?

Yes — but a sole director cannot also be the company secretary of the same company. In Singapore a director may also serve as the company's secretary, with one key restriction: where a company has only one director (a sole director), that director cannot simultaneously act as the company secretary, and a separate qualifying secretary must be appointed. This rule prevents one person from controlling both the director and secretary functions without any internal check. For small companies with a single director who is also the shareholder, it means appointing or designating another locally resident person as secretary — a direct reason many micro-businesses outsource the secretary function to a CSP. If the company has two or more directors, one of them may serve as secretary (provided they are a local resident and not the sole director).
