New York’s attorney-client privilege, as codified in CPLR §4503(a), protects against disclosure of a “confidential communication made between an attorney or his or her employee and the client in the course of professional employment.” The attorneys’ duty of confidentiality established by this statutory privilege is complemented by New York’s Rules of Professional Responsibility, which incorporates the privilege, and provides, with certain exceptions, that the attorney shall not reveal “confidential information” relating to the representation of the client. Rule 1.6(a).
