An agent can indeed be held liable for actions taken while representing the principal in several situations.

When the agent violates duties owed to the principal, such as acting against the principal’s interests or failing to perform responsibilities as agreed, the agent may be liable for any resulting damages or losses. This highlights the importance of the fiduciary duty an agent has towards the principal.

Additionally, if the agent exceeds their actual authority—meaning they act beyond the powers granted by the principal—they can be held responsible for any consequences that arise from those actions. This underscores the boundary set within the agent's scope of authority and the legal implications of overstepping it.

Moreover, if the agent explicitly assumes liability for a particular transaction, that agreement also exposes them to personal liability, regardless of the principal’s involvement. This scenario emphasizes the circumstances under which agents can be held accountable for their actions, particularly when they take on risk voluntarily.

Collectively, these scenarios illustrate that an agent's liability can arise from a breach of duty, exceeding authority, or explicitly accepting liability for specific actions, leading to the conclusion that all listed factors contribute to potential liability.
