Can a confidential communication between an attorney and a client be privileged from disclosure?

A communication, made in confidence, between an attorney and his or her client in which legal advice is sought or obtained is privileged from disclosure, unless the privilege is waived. See, e.g., United States v. Landof, 591 F.2d 36, 38 (9th Cir.1978). The privilege is not limited to actual communication by the client, but also applies to both the substance of the attorney's and the client's communication, including, but not limited to papers prepared by the attorney if the papers tend to reveal the confidential communications. Matter of Fischel, 557 F.2d 209, 211 (9th Cir.1977).
