The board of directors will usually have the authority to appoint a new director by passing a board resolution to approve the directors appointment.
Companies with amended articles of association may have included additional requirements around shareholder appointment or approval so you must always consult the articles to confirm if there are any additional requirements or restrictions.
To file the appointment with the Regulator, we will need:
the signed board or shareholder resolution,
a consent to act and fit & proper declaration signed by the person being appointed as the director.
