Which type of authority includes actual express authority, actual implied authority, and ostensible authority?

The type of authority that encompasses actual express authority, actual implied authority, and ostensible authority is referred to as the authority of the agent. This concept is fundamental in agency law, where an agent acts on behalf of a principal.

Actual express authority is the authority that the principal explicitly grants to the agent, often in written or spoken form. This can include the specific actions the agent is authorized to take. Actual implied authority, on the other hand, is not expressly stated but is inferred from the agent's role or position and the circumstances surrounding their actions. It allows the agent to carry out tasks that are necessary to fulfill their duties. Ostensible authority, also known as apparent authority, arises when a third party reasonably believes that the agent has the authority to act on behalf of the principal, based on the principal's representation or conduct.

In summary, the authority of the agent encompasses all these forms of authority, as it outlines the various ways an agent can be empowered to act on behalf of the principal, while the other options do not encompass the full spectrum of agency authority. Power of attorney, for example, is a legal document that grants specific powers but does not represent the broader concept of agency authority as a whole.
