Informal Opinion Number: 20030063

Rules: 4-1.7
Client-Lawyer Relationship
Conflict of Interest: Current Clients

Reference Note: Effective July 1, 2007, Rule 4-1.7 was amended. This opinion is based on Rule 4-1.7 in effect prior to that date.
QUESTION:
Attorney entered an appearance for defendant, Doctor A, in a medical malpractice case. When plaintiffs disclosed their expert, Attorney learned that Attorney had an ongoing professional and personal relationship with plaintiffs’ expert. Can Attorney continue to represent doctor A?
ANSWER: If there is a conflict of interest, it would be under Rule 4-1.7(b). If Attorney’s relationship with the expert will materially limit Attorney’s representation of Doctor A, a conflict exists. Even if Attorney does not believe the relationship would result in material limitation of Attorney’s representation, the relationship must be disclosed and discussed with Doctor A. If there is a conflict, but Attorney has a reasonable belief that it would not adversely affect representation, Doctor A could waive the conflict.
