"The concepts of lawyer confidentiality and attorney-client privilege both concern information that the lawyer must keep private and are protective of the client’s ability to confide freely in his or her lawyer, but the concepts are not synonymous. Terminology from both, such as “privileged information” or “waiver” are sometimes used interchangeably, further causing the differences between them to become somewhat blurred. However there are several critical differences between the two in their applicability and exceptions and the extent of information covered."
