Rule 504 - Lawyer-client PrivilegeN. J.S. 2A:84A-20 provides:
(1) General rule. Subject to Rule 37 [Rule 530 ] and except as otherwise provided by paragraph 2 of this rule communications between lawyer and his client in the course of that relationship and in professional confidence, are privileged, and a client has a privilege (a) to refuse to disclose any such communication, and (b) to prevent his lawyer from disclosing it, and (c) to prevent any other witness from disclosing such communication if it came to the knowledge of such witness (i) in the course of its transmittal between the client and the lawyer, or (ii) in a manner not reasonably to be anticipated, or (iii) as a result of a breach of the lawyer-client relationship, or (iv) in the course of a recognized confidential or privileged communication between the client and such witness. The privilege shall be claimed by the lawyer unless otherwise instructed by the client or his representative; the privilege may be claimed by the client in person, or if incompetent or deceased, by his guardian or personal representative. Where a corporation or association is the client having the privilege and it has been dissolved, the privilege may be claimed by its successors, assigns or trustees in dissolution. (2) Exceptions. Such privilege shall not extend (a) to a communication in the course of legal service sought or obtained in aid of the commission of a crime or a fraud, or (b) to a communication relevant to an issue between parties all of whom claim through the client, regardless of whether the respective claims are by testate or intestate succession or by inter vivos transaction, or (c) to a communication relevant to an issue of breach of duty by the lawyer to his client, or by the client to his lawyer. Where 2 or more persons have employed a lawyer to act for them in common, none of them can assert such privilege as against the others as to communications with respect to that matter. (3) Definitions. As used in this rule (a) "client" means a person or corporation or other association that, directly or through an authorized representative, consults a lawyer or the lawyer's representative for the purpose of retaining the lawyer or securing legal service or advice from him in his professional capacity; and includes an incompetent whose guardian so consults the lawyer or the lawyer's representative in behalf of the incompetent, (b) "lawyer" means a person authorized, or reasonably believed by the client to be authorized to practice law in any State or nation the law of which recognizes a privilege against disclosure of confidential communications between client and lawyer. A communication made in the course of relationship between lawyer and client shall be presumed to have been made in professional confidence unless knowingly made within the hearing of some person whose presence nullified the privilege.
