A recent Third District Court of Appeal decision clarifies when a shareholder may bring an action on his or her own behalf against a third-party or must bring the action on behalf of the corporation as a derivative shareholder suit. A derivative action is one brought by a shareholder on behalf of a corporation for damages sustained by the corporation. An example would be when an action of a third-party causes the devaluation of the stock of the corporation. Only the corporation can bring suit for that and any collection must be shared between all shareholders. Obviously, a shareholder would prefer to bring such an action in his or her own right so that any judgment would then only be in favor of the shareholder and he or she would not have to share the award with the other shareholders.
