Advisory on MSO, ABS and private-equity structures that bring growth capital and liquidity to law firms, while keeping the practice of law in lawyers’ hands.
Law firms can now access outside investment through private equity and family offices, for growth, technology, acquisitions or partner liquidity. The question is no longer whether, but how to do it without breaching professional-conduct rules.
Historically, the primary rule preventing private investors from legally investing directly into law firms in each US state is ABA Model Rule 5.4, which prohibits nonlawyer ownership of law firms or sharing fees with nonlawyers. This is being addressed by the Legal Managed Service Organization, which separates lawyers from the operational management of the firm.
Achelous Advisors advises firms and investors on the structures that make this possible: the Legal Managed Service Organization, Alternative Business Structures, and bespoke private-equity arrangements, and on which one fits a given firm, jurisdiction and goal.
A Legal Managed Service Organization (MSO) is a separate company that provides all of a firm’s non-legal business functions, technology, marketing, intake, HR, finance, real estate, under a long-term management services agreement. The MSO can take outside investment; the law firm itself stays 100% lawyer-owned, and the law firm can still own a percentage of the MSO, depending upon the valuation of the private equity investment.
Because the firm stays lawyer-owned, the MSO model works in most of the 50 US states, the most broadly viable route to outside capital today.
Investors own the operating company; lawyers own the firm. Works in most of the 50 states and in the UK and Australia. Returns come from service fees paid by the law firm, not legal-fee sharing.
True non-lawyer ownership of a law firm in the United States is allowed in Arizona, Utah, Washington D.C. and Puerto Rico, and internationally in both the United Kingdom (since 2011) and Australia.
Personal injury, mass tort, immigration and consumer practices with marketing-driven, scalable economics.
Partnerships needing investment in technology, AI, acquisitions or geographic expansion to compete at scale.
Founders seeking a partial or full liquidity event and an orderly path to retirement.
The MSO model is generally viable in all 50 US states because the law firm remains lawyer-owned. Full non-lawyer ownership under Alternative Business Structures is currently limited to Arizona, Utah, Washington D.C. and Puerto Rico in the US, and is well established in the UK and Australia.
No. You retain 100% ownership of the law practice and all professional decisions. The MSO owns only the business operations and is paid for the services it provides.
Through arm’s-length, market-rate service fees for the operational services it delivers, structured like any third-party vendor relationship, not as a share of legal fees.
ABS allows direct profit participation and investor governance but only in a few jurisdictions. The MSO works everywhere but separates legal fees from investor returns. The right answer depends on your firm, your markets and your goals.
Every engagement begins with a private, no-obligation conversation about your firm’s goals and how to achieve them in a particular practice area and in the current financial climate.
