Actual authority is the authority given by the principal to the agent and could be in written or oral form. The capacity of an agent to act is the same as the capacity of his/her principal. The express actual authority of an agent means that an agent has been told orally or in written form by the principal to act on his behalf. Hence, the agent’s authority may be restricted by the terms of agreement known as power of attorney.

However, in such a case, the third party may rely on the agent’s apparent
