Which of the following is NOT an authorized type of authority given to agents?

The correct choice is customary authority because it is not a defined or officially recognized type of authority granted to agents in the context of insurance. Agents typically operate under three primary types of authority: express authority, implied authority, and apparent authority.

Express authority refers to the explicitly written or verbal powers granted to an agent by the principal (the insurance company), clearly outlining what the agent is authorized to do on behalf of the company.

Implied authority encompasses the powers not specifically stated but are necessary for the agent to fulfill their express responsibilities. This authority allows agents to perform tasks that are necessary for completing transactions or fulfilling their role, even if those tasks are not explicitly outlined.

Apparent authority occurs when a third party perceives that an agent has the authority to act on behalf of the principal, based on the principal's representations. If a principal has led a third party to believe that the agent has certain powers, the agent can be held accountable even if those powers were not expressly granted.

Customary authority, on the other hand, is not a recognized term within the agency law framework and does not represent an official type of authority. Thus, it stands apart from the other three types of authority that agents may have.
