The Hong Kong Company Ordinance requires each private limited Hong Kong Company to appoint a company secretary. The company secretary will be the primary officer in charge of numerous administrative and reporting responsibilities a company is required to adhere to by law. These statutory requirements include (but not limited to) the filing of annual returns, and recording and filing of board resolutions.
If that secretary is an individual, they are required to reside in Hong Kong; if the secretary is a body corporate, their registered or principal office must be in Hong Kong.
A sole director/shareholder can not perform as company secretary.
