Attorneyclient privilege is a legal concept that ensures communications between a client and their lawyer are confidential and protected from disclosure. The attorney-client privilege protects confidential communications made during an attorney client relationship from disclosure.When the client is a corporation, the question of whose communications are privileged can be difficult to answer in practice. The attorneyclient privilege is a way to address communication to your outside or inhouse counsel when you need to send a message (ie, letter or email) However, many forget that lawyers have legal and ethical obligations that prevent them from disclosing your confidential and secret information. The administration of the attorney-client privilege in the case of corporations, however, presents special problems. The attorneyclient privilege is perhaps the bestknown of the many evidentiary privileges that exist under the law. The privilege is also waived when it is put at issue in a case. Some courts presume that a lawyer working in the corporation's legal department is providing legal advice. Every case is different just like every one of our clients.
