What level of agent authority is given when the principal gives the agent authority in writing?

Implied authority arises from the actions or circumstances surrounding the agent's role, rather than from explicit written or spoken instructions. This authority is inferred from the nature of the agent's position and responsibilities, meaning it does not require a formal written grant by the principal.

Apparent authority occurs when a third party reasonably believes that the agent has the authority to act on behalf of the principal, based on the principal's representations. This type of authority is not derived from a written agreement but rather from the principal’s conduct or statements that create a belief in the agent's authority.

Direct authority is not a recognized legal term in the context of agency relationships. Instead, it may refer to the immediate and straightforward instructions given to an agent, but it does not have a formal definition in agency law as express, implied, or apparent authority do.
