Rule 1.10. Imputation of Conflicts of Interest: General Rule.
(a) While lawyers are associated in a firm, none of them shall knowingly represent a client when any one of them practicing alone would be prohibited from doing so by Rules 1.7, or 1.9, unless the prohibition is based on a personal interest of the prohibited lawyer and does not present a significant risk of materially limiting the representation of the client by the remaining lawyers in the firm, or unless permitted by Rules 1.10(b) or (c).
(b) When a lawyer becomes associated with a firm, the firm may not knowingly represent a person in the same or a substantially related matter in which that lawyer, or a firm with which the lawyer was associated, had previously represented a client whose interests are materially adverse to that person and about whom the lawyer had acquired information protected by Rules 1.6 and 1.9(c) that is material to the matter unless:
(1) the disqualified lawyer is screened from any participation in the matter and is apportioned no part of the fee therefrom; and
(2) written notice is promptly given to the appropriate client to enable it to ascertain compliance with the provisions of this rule.
(c) When a lawyer has terminated an association with a firm, the firm is not prohibited from thereafter representing a person with interests materially adverse to those of a client represented by the formerly associated lawyer and not currently represented by the firm, unless:
(1) the matter is the same or substantially related to that in which the formerly associated lawyer represented the client; and
(2) any lawyer remaining in the firm has information protected by Rules 1.6 and 1.9(c) that is material to the matter.
(d) A disqualification prescribed by this Rule may be waived by the affected client under the conditions stated in Rule 1.7.
(e) While lawyers are associated in a firm, a prohibition in paragraphs (a) through (i) of Rule 1.8 that applies to any one of them shall apply to all of them.
(f) The disqualification of lawyers in a firm with former or current government lawyers is governed by Rule 1.11.
(g) The disqualification of lawyers in a firm with a former judge, arbitrator, mediator or other third-party neutral is governed by Rule 1.12.
(h) Where a lawyer in a firm is disqualified from a matter due to consultation with a prospective client pursuant to Rule 1.18(b) and (c), disqualification of other lawyers in the same firm is governed by Rule 1.18(d).
(i) The disqualification of a lawyer when another lawyer in the lawyer’s firm is likely to be called as a witness is governed by Rule 3.7.
Comment: Definition of ‘‘Firm’’
(1) For the purposes of the Rules of Professional Conduct, the term ‘‘firm’’ denotes lawyers in a law partnership, professional corporation, sole proprietorship or other association authorized to practice law; or lawyers employed in a legal services organization or in the legal department of a corporation or other organization. See Rule 1.0(c). Whether two or more lawyers constitute of firm within this definition depends on specific facts. See Rule 1.0, Comments (2)—(4).
Principles of Imputed Disqualification
(2) The rule of imputed disqualification stated in paragraph (a) gives effect to the principle of loyalty to the client as it applies to lawyers who practice in a law firm. Such situations can be considered from the premise that a firm of lawyers is essentially one lawyer for purposes of the rules governing loyalty to the client, or from the premise that each lawyer is vicariously bound by the obligation of loyalty owed by each lawyer with whom the lawyer is associated. Paragraph (a) operates only among the lawyers currently associated in a firm. When a lawyer moves from one firm to another, the situation is governed by paragraphs (b) and (c).
(3) The rule in paragraph (a) does not prohibit representation where neither questions of client loyalty nor protection of confidential information are presented. Where one lawyer in a firm could not effectively represent a given client because of strong political beliefs, for example, but that lawyer will do no work on the case and the personal beliefs of the lawyer will not materially limit the representation by others in the firm, the firm should not be disqualified. On the other hand, if an opposing party in a case were owned by a lawyer in the law firm, and others in the firm would be materially limited in pursuing the matter because of loyalty to that lawyer, the personal disqualification of the lawyer would be imputed to all others in the firm.
(4) The rule in paragraph (a) also does not prohibit representation by others in the law firm where the person prohibited from involvement in a matter is a nonlawyer, such as a paralegal or legal secretary. Nor does paragraph (a) prohibit representation if the lawyer is prohibited from acting because of events before the person became a lawyer, for example, work that the person did while a law student. Such persons, however, ordinarily must be screened from any personal participation in the matter to avoid communication to others in the firm of confidential information that both the nonlawyers and the firm have a legal duty to protect. See Rules 1.0(k) and 5.3.
(5) Rule 1.10(c) operates to permit a law firm, under certain circumstances, to represent a person with interests directly adverse to those of a client represented by a lawyer who formerly was associated with the firm. The Rule applies regardless of when the formerly associated lawyer represented the client. However, the law firm may not represent a person with interests adverse to those of a present client of the firm, which would violate Rule 1.7. Moreover, the firm may not represent the person where the matter is the same or substantially related to that in which the formerly associated lawyer represented the client and any other lawyer currently in the firm has material information protected by Rules 1.6 and 1.9(c).
(6) Rule 1.10(d) removes imputation with the informed consent of the affected client or former client under the conditions stated in Rule 1.7. The conditions stated in Rule 1.7 require the lawyer to determine that the representation is not prohibited by Rule 1.7(b) and that each affected client or former client has given informed consent to the representation. In some cases, the risk may be so severe that the conflict may not be cured by client consent. For a discussion of the effectiveness of client waivers of conflicts that might arise in the future, see Rule 1.7, Comment (22). For a definition of informed consent, see Rule 1.0(e).
(7) Where a lawyer has joined a private firm after having represented the government, imputation is governed by Rule 1.11(b) and (c), not this Rule. Under Rule 1.11(d), where a lawyer represents the government after having served clients in private practice, nongovernmental employment or in another government agency, former-client conflicts are not imputed to government lawyers associated with the individually disqualified lawyer.
(8) Where a lawyer is prohibited from engaging in certain transactions under Rule 1.8, paragraph (k) of that Rule, and not this Rule, determines whether that prohibition also applies to other lawyers associated in a firm with the personally prohibited lawyer.
(9) The disqualification of lawyers in a firm with a former judge, arbitrator, mediator or other third-party neutral is governed by Rule 1.12.
(10) Where a lawyer is disqualified from a matter as a result of a consultation with a prospective client pursuant to Rule 1.18(b) and (c), disqualification of the other lawyers in the firm is governed by Rule 1.18(d).
(11) The disqualification of a lawyer when another lawyer in the lawyer’s firm is likely to be called as a witness is governed by Rule 3.7.
