Ariz. R. Sup. Ct. ER 1.8
COMMENT [2021 AMENDMENT]
Business Transactions Between Client and Lawyer
 The risk to a client is greatest when the client expects the lawyers to represent the client in the transaction itself or when the lawyer's financial interest otherwise poses a significant risk that the lawyer's representation of the client will be materially limited by the lawyer's financial interest in the transaction. Here the lawyer's role requires that the lawyer must comply, not only with requirements of paragraph (a), but also with requirements of ER 1.7. Under that Rule, the lawyer must disclose the risks associated with the lawyer's dual role as both legal adviser and participant in the transaction, including when lawyers refer clients for nonlegal services provided in the firm by either the lawyer or nonlawyer in the firm or refer clients through a separate entity in which the lawyer has a financial interest, such as the risk that the lawyer will structure the transaction or give legal advice in a way that favors the lawyer's interests at the expense of the client. Moreover, the lawyer must obtain the client's informed consent. In some cases, the lawyer's interest may be such that ER 1.7 will preclude the lawyer from seeking the client's consent to the transaction.
 If the client is independently represented in the transaction, paragraph (a)(2) of this Rule is inapplicable, and the paragraph (a)(1) requirement for full disclosure is satisfied either by a written disclosure by the lawyer involved in the transaction or by the client's independent counsel. The fact that the client was independently represented in the transaction is relevant in determining whether the agreement was fair and reasonable to the client as paragraph (a)(1) further requires.
Use of Information Related to Representation
 Use of information relating to the representation to the disadvantage of the client violates the lawyer's duty of loyalty. Paragraph (b) applies when the information is used to benefit either the lawyer or a third person, such as another client or business associate of the lawyer. For example, if a lawyer learns that a client intends to purchase and develop several parcels of land, the lawyer may not use that information to purchase one of the parcels in competition with the client or to recommend that another client make such a purchase. The Rule does not prohibit uses that do not disadvantage the client. For example, a lawyer who learns a government agency's interpretation of trade legislation during the representation of one client may properly use that information to benefit other clients. Paragraph (b) prohibits disadvantageous use of client information unless the client gives informed consent, except as permitted or required by these Rules. See ERs 1.2(d), 1.6, 1.9(c), 1.14, 3.3, 4.1(b), 8.1 and 8.3.
Gifts to Lawyers
 A lawyer may accept a gift from a client, if the transaction meets general standards of fairness. For example, a simple gift such as a present given at a holiday or as a token of appreciation is permitted. If a client offers the lawyer or a related person a more substantial gift, paragraph (c) does not prohibit the lawyer or related person from accepting it, although such a gift may be voidable by the client under the doctrine of undue influence. In any event, due to concerns about overreaching and imposition on clients, a lawyer may not solicit a substantial gift to be made to the lawyer or related person, or for the benefit of the lawyer or a related person, except where the lawyer is related to the client as set forth in paragraph (c). Nothing in paragraph (c) is intended to interfere with a lawyer's efforts on behalf of a charitable institution, provided that the lawyer or related person has no financial interest in the charitable institution.
 If effectuation of a substantial gift requires preparing a legal instrument such as a will or conveyance, the client should have the detached advice that another lawyer can provide. The sole exception to this Rule is where the client is a relative of the donee.
 This Rule does not prohibit a lawyer from seeking to have the lawyer or a partner or associate of the lawyer named as executor of the client's estate or to another potentially lucrative fiduciary position. Nevertheless, such appointments will be subject to the general conflict of interest provision in ER 1.7 when there is a significant risk that the lawyer's interest in obtaining the appointment will materially limit the lawyer's independent professional judgment in advising the client concerning the choice of an executor or other fiduciary. In obtaining the client's informed consent to the conflict, the lawyer should advise the client concerning the nature and extent of the lawyer's financial interest in the appointment, as well as the availability of alternative candidates for the position.
 An agreement by which a lawyer acquires literary or media rights concerning the conduct of the representation creates a conflict between the interests of the client and the personal interests of the lawyer. Measures suitable in the representation of the client may detract from the publication value of an account of the representation. Paragraph (d) does not prohibit a lawyer representing a client in a transaction concerning literary property from agreeing that the lawyer's fee shall consist of a share in ownership in the property, if the arrangement conforms to ER 1.5 and paragraphs (a) and (i).
 Lawyers may not subsidize lawsuits or administrative proceedings brought on behalf of their clients, including making or guaranteeing loans to their clients for living expenses, because to do so would encourage clients to pursue lawsuits that might not otherwise be brought and because such assistance gives lawyers too great a financial stake in the litigation. These dangers do not warrant a prohibition on a lawyer lending a client court costs and litigation expenses, including the expenses of medical examination and the costs of obtaining and presenting evidence, because these advances are virtually indistinguishable from contingent fees and help ensure access to the courts. Similarly, an exception allowing lawyers representing indigent clients to pay court costs and litigation expenses regardless of whether these funds will be repaid is warranted.
Person Paying for Lawyer's Services
 Lawyers are frequently asked to represent a client under circumstances in which a third person will compensate the lawyer, in whole or in part. The third person might be a relative or friend, an indemnitor (such as a liability insurance company) or a co-client (such as a corporation sued along with one or more of its employees). Because third-party payers frequently have interests that differ from those of the client, including interests in minimizing the amount spent on the representation and in learning how the representation is progressing, lawyers are prohibited from accepting or continuing such representations unless the lawyer determines that there will be no interference with the lawyer's independent professional judgment and there is informed consent from the client. See also ER 5.4(c) (prohibiting interference with a lawyer's professional judgment by one who recommends, employs or pays the lawyer to render legal services for another).
 Sometimes, it will be sufficient for the lawyer to obtain the client's informed consent regarding the fact of the payment and the identity of the third-party payer. If, however, the fee arrangement creates a conflict of interest for the lawyer, then the lawyer must comply with ER 1.7. The lawyer must also conform to the requirements of ER 1.6 concerning confidentiality. Under ER 1.7(a), a conflict of interest exists if there is significant risk that the lawyer's representation of the client will be materially limited by the lawyer's own interest in the fee arrangement or by the lawyer's responsibilities to the third-party payer (for example, when the third-party payer is a co-client). Under ER 1.7(b), the lawyer may accept or continue the representation with the informed consent of each affected client, unless the conflict is nonconsentable under that paragraph. Under ER 1.7(b), the informed consent must be confirmed in writing.
 Differences in willingness to make or accept an offer of settlement are among the risks of common representation of multiple clients by a single lawyer. Under ER 1.7, this is one of the risks that should be discussed before undertaking the representation, as part of the process of obtaining the clients' informed consent. In addition, ER 1.2(a) protects each client's right to have the final say in deciding whether to accept or reject an offer of settlement and in deciding whether to enter a guilty or nolo contendere plea in a criminal case. The rule stated in this paragraph is a corollary of both these Rules and provides that, before any settlement offer or plea bargain is made or accepted on behalf of multiple clients, the lawyer must inform each of them about all the material terms of the settlement, including what the other clients will receive or pay if the settlement or plea offer is accepted. See also ER 1.0(e) (definition of informed consent). This rule does not apply to lawyers representing governmental agencies or officials unless, in the particular action, there is a potential for a conflict of interest between the jointly represented government agencies or officials on the issue of settlement. Lawyers representing a class of plaintiffs or defendants, or those proceeding derivatively, may not have a full client-lawyer relationship with each member of the class; nevertheless such lawyers must comply with applicable rules regulating notification of class members and other procedural requirements designed to ensure adequate protection of the entire class.
Limiting Liability and Settling Claims
 Agreements prospectively limiting a lawyer's liability for malpractice, whether made at the outset of the representation or at any time when the client is unaware of a claim or potential claim, are prohibited unless the client is independently represented in making the agreement because they are likely to undermine competent and diligent representation. Also, many clients are unable to evaluate the desirability of making such an agreement before a dispute has arisen, particularly if they are then represented by the lawyer seeking the agreement. This paragraph does not, however, prohibit a lawyer from entering into an agreement with the client to arbitrate legal malpractice claims, provided such agreements are enforceable and the client is fully informed of the scope and effect of the agreement. Nor does this paragraph limit the ability of lawyers to practice in the form of a limited-liability entity, where permitted by law, provided that each lawyer remains personally liable to the client for that lawyer's own conduct and the firm complies with any conditions required by law, such as provisions requiring client notification or maintenance of adequate liability insurance. Nor does it prohibit an agreement in accordance with ER 1.2 that defines the scope of the representation, although a definition of scope that makes the obligations of representation illusory will amount to an attempt to limit liability.
 Agreements settling a claim or a potential claim for malpractice are not prohibited by this Rule. Nevertheless, in view of the danger that a lawyer will take unfair advantage of an unrepresented client or former client, the lawyer must first advise such a person in writing of the appropriateness of independent representation in connection with such a settlement. In addition, the lawyer must give the client or former client a reasonable opportunity to find and consult independent counsel. Notwithstanding the provisions of paragraph (h)(3), agreements that purport to limit a person's ability to report professional misconduct are not binding on disciplinary authorities.
Acquiring Proprietary Interest in Litigation
 Paragraph (i) states the traditional general rule that lawyers are prohibited from acquiring a proprietary interest in litigation. Like paragraph (e), the general rule has its basis in common law champerty and maintenance and is designed to avoid giving the lawyer too great an interest in the representation. In addition, when the lawyer acquires an ownership interest in the subject of the representation, it will be more difficult for a client to discharge the lawyer if the client so desires. The Rule is subject to specific exceptions developed in decisional law and continued in these Rules. The exception for certain advances of the costs of litigation is set forth in paragraph (e). In addition, paragraph (i) sets forth exceptions for liens authorized by law to secure the lawyer's fees or expenses and contracts for reasonable contingent fees. The law of each jurisdiction determines which liens are authorized by law. These may include liens granted by statute, liens originating in common law and liens acquired by contract with the client. When a lawyer acquires by contract a security interest in property other than that recovered through the lawyer's efforts in the litigation, such an acquisition is a business or financial transaction with a client and is governed by the requirements of paragraph (a). Contracts for contingent fees in civil cases are governed by ER 1.5.
Client-Lawyer Sexual Relationships
 The relationship between lawyer and client is a fiduciary one in which the lawyer occupies the highest position of trust and confidence. The relationship is almost always unequal; thus, a sexual relationship between lawyer and client can involve unfair exploitation of the lawyer's fiduciary role, in violation of the lawyer's basic ethical obligation not to use the trust of the client to the client's disadvantage. In addition, such a relationship presents a significant danger that, because of the lawyer's emotional involvement, the lawyer will be unable to represent the client without impairment of the exercise of independent professional judgment. Moreover, a blurred line between the professional and personal relationships may make it difficult to predict to what extent client confidences will be protected by the attorney-client evidentiary privilege, since client confidences are protected by privilege only when they are imparted in the context of the client-lawyer relationship. Because of the significant danger of harm to client interests and because the client's own emotional involvement renders it unlikely that the client could give adequate informed consent, this Rule prohibits the lawyer from having sexual relations with a client regardless of whether the relationship is consensual and regardless of the absence of prejudice to the client.
 Sexual relationships that predate the client-lawyer relationship are not prohibited. Issues relating to the exploitation of the fiduciary relationship and client dependency are diminished when the sexual relationship existed prior to the commencement of the client-lawyer relationship. However, before proceeding with the representation in these circumstances, the lawyer should consider whether the lawyer's ability to represent the client will be materially limited by the relationship. See ER 1.7(a)(2).
 When the client is an organization, paragraph (j) of this Rule prohibits a lawyer for the organization from having a sexual relationship with a constituent of the organization who supervises, directs or regularly consults with that lawyer concerning the organization's legal matters.
Imputation of Prohibitions
 Under paragraph (k), a prohibition on conduct by an individual lawyer in paragraphs (a) through (i) also applies to all lawyers associated in a firm with the personally prohibited lawyer. For example, one lawyer in a firm may not enter into a business transaction with a client of another member of the firm without complying with paragraph (a), even if the first lawyer is not personally involved in the representation of the client. The prohibition set forth in paragraphs (j) and (l) are personal and are not applied to associated lawyers.
Personal Relationships Between Lawyers
 ER 1.8 (l) applies to related lawyers who are in different firms. A lawyer related to another lawyer, e.g., as parent, child, sibling, spouse or cohabitant ordinarily may not represent a client in a matter where the other lawyer is representing another party, unless each client gives informed consent. The disqualification arising from the relationship is personal and ordinarily is not imputed to members of firms with whom the lawyers are associated. See ER 1.10.
