Rule 1.7 - Conflict of Interest: Current Clients(a) Except as provided by 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 same matter before a tribunal; and(4) each affected client gives informed consent, confirmed in writing.SDCL app TO CHAPTER 16-18 r. 1.7
