Major US law firms explore PE investment through alternative ownership structures
Several of the largest US law firms are assessing whether alternative ownership models could open the door to private equity investment, as firms seek new sources of capital to fund growth, technology investment and talent acquisition, according to a report by the Financial Times.
According to reports, firms including Paul Weiss, Quinn Emanuel and Proskauer have held discussions with private equity investors or financial advisers about so-called management services organisation (MSO) structures, which are designed to comply with US rules prohibiting non-lawyer ownership of legal practices.
Under the model, a law firm’s legal practice remains owned by lawyers, while a separate entity responsible for administrative services, technology, intellectual property and other business functions can accept outside investment. The legal partnership then pays the MSO for those services.
The structure has already been used in sectors such as healthcare and accountancy, where professional ownership rules have similarly limited private equity participation.
Quinn Emanuel is reported to have held discussions with investment bank Guggenheim Securities to better understand potential investment structures, although no formal sale process has been launched. Paul Weiss confirmed it had listened to presentations from potential investors but said it is not currently pursuing a transaction. Proskauer is also understood to have met with at least one private equity firm, while White & Case has reportedly established an internal group to examine the model.
Interest from private equity reflects growing demand for exposure to professional services businesses with resilient revenues and attractive long-term growth prospects. For law firms, access to external capital could help finance investment in artificial intelligence, technology platforms and lateral partner recruitment, while also providing new ways to incentivise and retain top-performing lawyers.
However, the concept remains controversial within the legal industry. Critics argue that private equity involvement could alter partnership economics, create governance challenges and discourage high-profile lawyers from joining firms backed by financial sponsors. Others question whether older partners could benefit disproportionately from monetising part of their firm’s value.
Private equity investors are also approaching the sector cautiously. While the legal industry offers attractive recurring revenue characteristics, the MSO model has yet to be tested at scale among leading US law firms and could face future regulatory scrutiny.
Outside the US, law firm investment has begun to gather momentum. Offshore firm Mourant recently sold a minority stake to MML, while UK-based sports specialist Northridge Law secured investment from Cordillera Investment Partners earlier this year. Offshore practice Appleby is also reportedly evaluating strategic investment options.
Although no major US law firm has yet completed a large-scale private equity transaction using an MSO structure, the growing number of exploratory discussions suggests sponsors and legal partnerships are increasingly examining whether alternative ownership models could reshape the sector.
