The correct answer is C. The CFE Manual explains that legal professional privileges generally protect confidential communications between a professional legal advisor and a client when the communications are made for the purpose of giving or receiving legal advice. Thus, the usual elements include a communication between lawyer and client, a legal-advice purpose, and an intent that the communication remain confidential.

A written contract requiring confidentiality is not typically required for the privilege to apply. The privilege arises from the nature of the relationship and the purpose and confidentiality of the communication, not from a separate written agreement. Of course, engagement letters or representation agreements may exist in practice, but they are not themselves a standard legal element of privilege. That is why option C is the only choice that does not usually need to be present.

This distinction is important for fraud examiners because privileged communications can extend beyond direct attorney-client conversations in some circumstances, including communications with nonlawyer professionals assisting counsel, provided the communications remain confidential and are tied to legal advice. But the existence of privilege still does not depend on a written confidentiality contract. Therefore, C is the most accurate answer.
