An "attorney-in-fact" is an authorization to act on someone else's behalf in a legal or business matter. The person authorizing the other to act is the "principal" or the grantor of the power, and the one authorized to act is the "agent" or "attorney-in-fact." The scope of the agent's authority is limited to that given by the power of attorney, which may be limited to one specific transaction or act or may be much broader. The attorney-in-fact need not actually be a licensed attorney. See "Agent".
