(b) the client either is represented in the transaction or acquisition by an independent lawyer of the client’s choice or the client is advised in writing* to seek the advice of an independent lawyer of the client’s choice and is given a reasonable* opportunity to seek that advice; and

(c) the client thereafter provides informed written consent* to the terms of the transaction or acquisition, and to the lawyer’s role in it.

Notes and commentary — not rule text

Comment

[1] A lawyer has an “other pecuniary interest adverse to a client” within the meaning of this rule when the lawyer possesses a legal right to significantly impair or prejudice the client’s rights or interests without court action. (See Fletcher v. Davis (2004) 33 Cal.4th 61, 68 [14 Cal.Rptr.3d 58]; see also Bus. & Prof. Code, § 6175.3 [Sale of financial products to elder or dependent adult clients; Disclosure]; Fam. Code, §§ 2033-2034 [Attorney lien on community real property].) However, this rule does not apply to a charging lien given to secure payment of a contingency fee. (See Plummer v. Day/Eisenberg, LLP (2010) 184 Cal.App.4th 38 [108 Cal.Rptr.3d 455].)

[2] For purposes of this rule, factors that can be considered in determining whether a lawyer is independent include whether the lawyer: (i) has a financial interest in the transaction or acquisition; and (ii) has a close legal, business, financial, professional or personal relationship with the lawyer seeking the client’s consent.

[3] Fairness and reasonableness under paragraph (a) are measured at the time of the transaction or acquisition based on the facts that then exist.

[4] In some circumstances, this rule may apply to a transaction entered into with a former client. (Compare Hunniecutt v. State Bar (1988) 44 Cal.3d 362, 370-71 [“[W]hen an attorney enters into a transaction with a former client regarding a fund which resulted from the attorney’s representation, it is reasonable to examine the relationship between the parties for indications of special trust resulting therefrom. We conclude that if there is evidence that the client placed his trust in the attorney because of the representation, an attorney-client relationship exists for the purposes of [the predecessor rule] even if the representation has otherwise ended [and] It appears that [the client] became a target of [the lawyer’s] solicitation because he knew, through his representation of her, that she had recently received the settlement fund [and the court also found the client to be unsophisticated].”] with Wallis v. State Bar (1942) 21 Cal.2d 322 [finding lawyer not subject to discipline for entering into business transaction with a former client where the former client was a sophisticated businesswoman who had actively negotiated for terms she thought desirable, and the transaction was not connected with the matter on which the lawyer previously represented her].)

[5] This rule does not apply to the agreement by which the lawyer is retained by the client, unless the agreement confers on the lawyer an ownership, possessory, security, or other pecuniary interest adverse to the client. Such an agreement is governed, in part, by rule 1.5. This rule also does not apply to an agreement to advance to or deposit with a lawyer a sum to be applied to fees, or costs or other expenses, to be incurred in the future. Such agreements are governed, in part, by rules 1.5 and 1.15.

[6] This rule does not apply: (i) where a lawyer and client each make an investment on terms offered by a third person* to the general public or a significant portion thereof; or (ii) to standard commercial transactions for products or services that a lawyer acquires from a client on the same terms that the client generally markets them to others, where the lawyer has no advantage in dealing with the client.
