Make sure you know who your members are
If your charity is a Company Limited by Guarantee (CLG), a lack of clarity about who precisely are your members can lead to unintentional breaches of company law and/or your Constitution. It also can create confusion as to who are entitled to vote at general meetings and who should receive company information.
Members of the company are those persons or entities which hold an interest in the company (in companies with share capital, e.g. limited or PLC companies; they would be shareholders). It is possible that your members are the same as your directors. When a director is replaced their membership interest should be passed to the new director.
