Circular 230 § 10.29 — Conflicting interests.

(a) Except as provided by paragraph (b) of this section, a practitioner shall not represent a client in his or her practice before the Internal Revenue Service if the representation involves a conflict of interest. A 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 practitioner's responsibilities to another client, a former client or a third person or by a personal interest of the practitioner.

(b) Notwithstanding the existence of a conflict of interest under paragraph (a) of this section, the practitioner may represent a client if:

(1) The practitioner reasonably believes that the practitioner will be able to provide competent and diligent representation to each affected client;

(2) The representation is not prohibited by law;

(3) Each affected client gives informed consent, confirmed in writing.

(c) Copies of the written consents must be retained by the practitioner for at least 36 months from the date of the conclusion of the representation of the affected clients and the written consents must be provided to any officer or employee of the Internal Revenue Service on request.
