Rule 2-200 Financial Arrangements Among Lawyers
(A) A member shall not divide a fee for legal services with a lawyer who is not a partner of, associate of, or shareholder with the member unless:
(1) The client has consented in writing thereto after a full disclosure has been made in writing that a division of fees will be made and the terms of such division; and
(2) The total fee charged by all lawyers is not increased solely by reason of the provision for division of fees and is not unconscionable as that term is defined in rule 4-200.
(B) Except as permitted in paragraph (A) of this rule or rule 2-300, a member shall not compensate, give, or promise anything of value to any lawyer for the purpose of recommending or securing employment of the member or the member’s law firm by a client, or as a reward for having made a recommendation resulting in employment of the member or the member’s law firm by a client. A member’s offering of or giving a gift or gratuity to any lawyer who has made a recommendation resulting in the employment of the member or the member’s law firm shall not of itself violate this rule, provided that the gift or gratuity was not offered in consideration of any promise, agreement, or understanding that such a gift or gratuity would be forthcoming or that referrals would be made or encouraged in the future.
