Attorney-in-fact
Attorney-in-fact: An agent authorized to act for another person under a power of attorney. An attorney-in-fact does not need to be a lawyer and cannot practice law for the principal unless licensed; the agent owes the principal duties such as acting in good faith and within the scope of the authority granted.

What attorney-in-fact means
