The express authority takes place between the agent and the company and is specifically granted to an agent.
The implied authority falls under the heading of the “doctrine of ostensible authority” and also exists between the agent and the corporation. It provides that the agent has the capacity to act in a manner the public may reasonably believe is within his or her normal duties.
The apparent authority takes place between the agent and a company but deals with what a third party is led to believe. This doctrine holds a company liable for the agent’s actions.
