Rule 1.7 . Conflict of Interest: Current Clients.

(a) Except as provided in paragraph (b), a lawyer shall not represent a client if the representation involves a concurrent conflict of interest. A concurrent conflict of interest exists if: (1) The representation of one client will be directly adverse to another client; or (2) There is a significant risk that the representation of one or more clients will be materially limited by the lawyer’s responsibilities to another client, a former client or a third person or by a personal interest of the lawyer. (b) Notwithstanding the existence of a concurrent conflict of interest under paragraph (a), a lawyer may represent a client if: (1) The lawyer reasonably believes that the lawyer will be able to provide competent and diligent representation to each affected client; (2) The representation is not prohibited by law; (3) The representation does not involve the assertion of a claim by one client against another client represented by the lawyer in the same litigation or other proceeding before a tribunal; and (4) Each affected client gives informed consent, confirmed in writing.
