In almost every U.S. state, a non-lawyer cannot be a partner in a law firm. The American Bar Association’s Model Rule 5.4, which nearly every jurisdiction has adopted in some form, bars lawyers from forming a partnership with a non-lawyer when any of the partnership’s activities involve the practice of law, and prohibits sharing legal fees with non-lawyers outside a handful of narrow exceptions. Three jurisdictions have carved out their own paths: Washington, D.C. has permitted non-lawyer partners under tight conditions since 1991, and Arizona and Utah opened new routes in 2020.
Why the Rule Exists
Rule 5.4 is built to protect a lawyer’s independent professional judgment. If someone who isn’t bound by legal ethics rules owns part of a firm, that person’s financial interests could pressure lawyers to over-bill, cut corners, or push clients toward outcomes that pay better rather than outcomes that help.
Rule 5.4(a) states that a lawyer or law firm “shall not share legal fees with a nonlawyer.” Rule 5.4(b) states that a lawyer “shall not form a partnership with a nonlawyer if any of the activities of the partnership consist of the practice of law.”1American Bar Association. Rule 5.4 – Professional Independence of a Lawyer Rule 5.4(c) adds that a lawyer cannot let a person who recommends, employs, or pays the lawyer direct or regulate the lawyer’s professional judgment on a client matter. Together these provisions wall off ownership, management, and legal fee revenue from anyone who isn’t a lawyer.
The ABA’s House of Delegates has formally resolved that fee-sharing with non-lawyers is “inconsistent with the core values of the legal profession” and that the prohibition “should not be revised.”
Where Non-Lawyer Ownership Is Allowed
Washington, D.C.
D.C. has permitted non-lawyer partners since 1991 and is the most established exception in the country. Under D.C.’s version of Rule 5.4(b), a lawyer may form a partnership with a non-lawyer only if several conditions are satisfied: the non-lawyer must perform professional services that assist the firm’s legal practice, the firm’s sole purpose must be providing legal services to clients, and every person with ownership or managerial authority must agree to abide by the D.C. Rules of Professional Conduct.2DC Bar. Rule 5.4 – Professional Independence of a Lawyer
In practice that means a lobbyist, economist, or similar professional who actually works alongside the firm’s lawyers can hold an ownership interest. A passive investor who just writes a check cannot. The D.C. Bar has also proposed changing “sole purpose” to “principal purpose,” which would let D.C. firms with non-lawyer owners also offer related services such as lobbying or consulting without running afoul of the rule.3DC Bar.

Arizona
The Arizona Supreme Court repealed its version of Rule 5.4’s ban on non-lawyer co-ownership, concluding that it was an economic restriction rather than a genuine ethics rule. On January 1, 2021, Arizona’s Alternative Business Structure (ABS) program went into effect, creating a licensing system for law firms with non-lawyer economic interests. By the end of 2024, the program had issued at least 116 initial licenses, with 115 actively operating.
An ABS license is not a formality. Every owner, manager, and officer undergoes a background check covering fraud, dishonesty, professional discipline, criminal history, and financial misconduct.4Arizona Supreme Court.

Utah
Utah created a regulatory sandbox in August 2020. Rather than repealing Rule 5.4 outright, the Utah Supreme Court grants approved entities a waiver of the non-lawyer ownership prohibition and, in some cases, the unauthorized-practice-of-law rules.6Utah Office of Legal Services Innovation. The Utah Legal Regulatory Sandbox The sandbox is in Phase 2 and currently authorized through August 2027.
Participation has shifted over time. The sandbox had 39 entrants in 2022 and 11 as of April 2025. Entry requires a $5,000 annual fee, and participants must collect consumer data and respond to consumer complaints.7Utah Office of Legal Services Innovation. Sandbox Resources The Utah Supreme Court has formed a committee to evaluate the results and recommend whether any changes should become permanent.
Financial Arrangements That Are Allowed
Rule 5.4 is not a total firewall between lawyers and non-lawyers. People often confuse what the rule actually bans with what it permits, so the carve-outs are worth knowing:
- A law firm can include non-lawyer employees in a retirement or compensation plan based on the firm’s overall profitability. The arrangement cannot be tied to fees from a particular case.
- A firm can continue paying money to a deceased lawyer’s estate or designated beneficiaries under an existing agreement, and a lawyer who buys the practice of a deceased, disabled, or disappeared lawyer can pay the agreed purchase price to that lawyer’s estate.1American Bar Association. Rule 5.4 – Professional Independence of a Lawyer
- A lawyer may share court-awarded legal fees with a nonprofit organization that employed, retained, or recommended them for the case.1American Bar Association. Rule 5.4 – Professional Independence of a Lawyer
None of these create anything close to a partnership. A profit-indexed retirement benefit for a firm administrator is not the same as that administrator having a voice in how the firm runs its cases.
What Happens If You Try It Anyway
Attempting to set up a non-lawyer partnership in a jurisdiction that forbids it carries real exposure for everyone involved.
The lawyer faces professional discipline. State bars can impose sanctions ranging from a reprimand to suspension or disbarment. Fee-sharing with a non-lawyer can also trigger a separate violation of rules on referral fees, stacking the exposure.
The non-lawyer can be charged with unauthorized practice of law. Penalties vary widely across states, from civil fines in some jurisdictions to misdemeanor or felony prosecution in others, with potential imprisonment on the heavier end.
The agreement itself is likely unenforceable. Courts have treated fee-sharing contracts between lawyers and non-lawyers as void against public policy. In one case, a non-lawyer who was allegedly promised a consulting fee plus a five-percent share of a law firm’s annual profits in certain cases had every claim dismissed; the court found the entire arrangement violated public policy and refused to enforce any part of it. If you are the non-lawyer and the lawyer backs out, you have no reliable way to recover.
What Non-Lawyers Can Do at a Law Firm
Non-lawyers are essential to how firms actually run, even in states with the full Rule 5.4 prohibition. They fill administrative, marketing, human resources, information technology, and financial roles without any ethics problem, so long as they do not give legal advice, exercise independent legal judgment on client matters, or hold ownership.
Paralegals and legal assistants work under attorney supervision on legal research, document drafting, case file organization, client interviews, and trial preparation. What they cannot do is form an attorney-client relationship, set fees, give legal advice, or become partners or shareholders.8American Bar Association. Information for Lawyers – How Paralegals Can Improve Your Practice The line is between supporting the practice of law and practicing it, and ownership sits on the practice side of that line everywhere except D.C., Arizona, and the Utah sandbox.
