Rule 3-320 Relationship With Other Party's Lawyer
A member shall not represent a client in a matter in which another party's lawyer is a spouse, parent, child, or sibling of the member, lives with the member, is a client of the member, or has an intimate personal relationship with the member, unless the member informs the client in writing of the relationship.
Discussion:
Rule 3-320 is not intended to apply to circumstances in which a member fails to advise the client of a relationship with another lawyer who is merely a partner or associate in the same law firm as the adverse party's counsel, and who has no direct involvement in the matter. (Amended by order of Supreme Court, operative September 14, 1992.)
