Partnerships With Nonlawyers
The Core Prohibition
Rule 5.4(b) of the Model Rules of Professional Conduct says it in one sentence: a lawyer shall not form a partnership with a nonlawyer if any of the activities of the partnership consist of the practice of law.1 The rule has one trigger and one command. The trigger is a partnership between a lawyer and a person without a law license, one of whose activities is law practice. The command is flat: do not form it. The text sets out no balancing of costs and benefits, makes no exception for careful lawyers, and does not ask whether the nonlawyer ever interfered with a client matter. Forming the partnership is the violation.
Commentators read the rule the same way. Footnotes in Cincinnati Insurance Co. v. Wills, 717 N.E.2d 151 (Ind. 1999), quote Hazard and Hodes on Rule 5.4(b): it "flatly prohibits a lawyer from sharing the profits and losses of a law practice with a nonlawyer," and it "applies even though the lawyer retains control over all legal aspects of the business."2 That passage is commentary, not the court's holding, but it describes the rule's structure accurately. The rule asks about the form of the association and the nature of its activities. It never asks who has the last word on a legal question.
That flatness sets the rule apart from ordinary conflict analysis. A conflict inquiry examines a particular representation and asks whether the lawyer's judgment was likely compromised. The partnership ban looks only at structure. The danger it targets comes from the shared financial stake, and that stake exists from the day the partnership forms, whoever holds formal decision-making power. A rule keyed to who has final authority would let every combined practice claim that its lawyers were in charge. The only check would be an after-the-fact audit of the firm's internal dealings.
The profession has three concerns about lay participants in a legal business. The commentary quoted in the Wills footnotes lists them: nonlawyers who are part of the business arrangement may practice law, may learn client confidences, and may impair the lawyer's independent professional judgment.3 The same commentary explains why law practice is reserved to lawyers. Rules 5.4 and 5.5 restrict it to lawyers on the theory that only lawyers have the qualifications to practice competently and according to the rules of professional discipline.4
The accountant shows the first danger at work. Suppose a lawyer and an accountant split a fee according to the time each devotes to the client's problem. The accountant can enlarge his share by spending more time on advice that drifts from financial matters into legal ones, which belong to the licensed lawyer.5 The profession has long been wary of both fee sharing with nonlawyers and law practices in which nonlawyers hold an ownership or managerial role. It sees both as likely to undermine the lawyer's professional independence.6
The discipline gap compounds the problem. The Rules do not apply to nonlawyers, so, as Professors Rotunda and Dzienkowski observe, the bar would have trouble regulating the profession if nonlawyers outside law firms had an incentive to profit from the practice of law.7 A lay partner who shares in the profits of legal work has exactly that incentive and sits beyond the bar's reach.
Subsection (b) is one of several overlapping restraints in Rule 5.4. Rule 5.4(a) bars a lawyer or law firm from sharing legal fees with a nonlawyer, subject to a short list of exceptions.8 It also protects the client's expectation that the relationship is solely with the lawyer, with no undisclosed third person holding a stake in the matter or taking part in the representation.9 Rule 5.4(c) bars a lawyer from letting a person who recommends, employs, or pays her direct or regulate her professional judgment.10 Rule 5.4(d) bars practice through a professional corporation or association authorized to practice law for a profit if a nonlawyer owns any interest, is a corporate director or officer, or has the right to direct or control a lawyer's professional judgment. The only ownership carve-out is the temporary interest held by the fiduciary representative of a lawyer's estate.11 Read together, these provisions mean that a lawyer may not practice in any arrangement where a layperson holds authority or control that intrudes on the client relationship or on the lawyer's judgment. In nearly every state today, the answer to whether a lawyer may practice in partnership with a nonlawyer is an emphatic no.12
The same rule bars multidisciplinary practice, a fee-sharing association of lawyers and nonlawyers in a firm that delivers both legal and nonlegal services. Under Rule 5.4, a lawyer cannot share legal fees with nonlawyers, form a partnership involving the practice of law with nonlawyers, form a law firm in which a nonlawyer has an interest, or allow a nonlawyer to direct her professional judgment.13 The sections that follow map where the rule reaches and where it stops, and a later section takes up the debate over relaxing it, including the District of Columbia's exception.
