For an arbitration provision in a retainer agreement to be enforceable, an attorney must generally explain to a client the benefits and disadvantages of arbitrating a prospective dispute between the attorney and client. Such an explanation is necessary because, to make an informed decision, the client must have a basic understanding of the fundamental differences between an arbitral forum and a judicial forum in resolving a future fee dispute or malpractice action. See RPC 1.4(c). That information can be conveyed in an oral dialogue or in writing, or by both, depending on how the attorney chooses best to communicate it. The Court refers the issues raised in this opinion to the Advisory Committee on Professional Ethics, which may propose further guidance on the scope of an attorney’s disclosure requirements. The new mandate will apply prospectively, except as to Delaney, who must be allowed to proceed with his malpractice action in the Law Division.
