Rules of Professional Conduct
A member shall not induce a client to make a substantial gift, including a testamentary gift, to the member or to the member's parent, child, sibling, or spouse, except where the client is related to the member.
A member may accept a gift from a member's client, subject to general standards of fairness and absence of undue influence. The member who participates in the preparation of an instrument memorializing a gift which is otherwise permissible ought not to be subject to professional discipline. On the other hand, where impermissible influence occurred, discipline is appropriate. (See Magee v. State Bar (1962) 58 Cal.2d 423 [24 Cal.Rptr. 839].)
