The attorney client privilege is designed to encourage full and frank communication between attorneys and their clients.

By Patrick McCormick. A client places the privileged communications at issue in a legal proceeding. There must be an expectation that the communication will not be disclosed. Readers requiring legal advice on any specific case or circumstance should consult with counsel admitted in the relevant jurisdiction. If the purpose is legal advice, the communication is privileged if it's confidential and between lawyer and client. One final consideration arises in the context of in-house counsel.
