I often get asked about the attorney-client privilege and what it means and whether anything said to an attorney is confidential.  I usually answer that yes, as a general matter, anything said between an attorney and client is confidential and cannot be used against the client unless the client consents or they themself divulge information about the conversation.  There are exceptions, of course.  If the conversation is between a third-party then it is not private, unless that third-party is working for the attorney.  Also, if the client divulges that he/she will commit a serious/violent crime in the very near future than the attorney generally has a duty to report that information.  Otherwise, everything is confidential and the confidentiality generally last forever (even beyond the death of the client, usually).
