THE ATTORNEY–CLIENT PRIVILEGE GUARANTEES THAT COMmunications between an attorney and client are not admissible in court. It is the oldest and most powerful evidentiary privilege and shields communications between lawyers and clients from disclosure in almost all settings. The attorney work product doctrine covers both the discovery process and admissibility in court. It gives limited protection to documents created in anticipation of litigation and absolute protection to the thoughts, opinions, and strategies of a lawyer preparing for trial. Between these two doctrines, lawyers are able to guarantee confidentiality to clients and prepare their cases for trial with little worry about what might or might not be discoverable by the opposing party. This is obviously a substantial selling point to clients and also makes every lawyer's job much easier.
