A shareholder of corporate stock refers to an individual or legal entity that is registered by the corporation as the legal owner of shares of the share capital of a public or private corporation. Shareholders may be referred to as members of a corporation. A person or legal entity becomes a shareholder in a corporation when their name and other details are entered in the corporation's register of shareholders or members, and unless required by law the corporation is not required or permitted to enquire as to the beneficial ownership of the shares. A corporation generally cannot own shares of itself.
