Private equity expansion into personal injury law firms: Key considerations

Private equity (PE)’s demand for professional services has surged in recent years, and personal injury (PI) law firms have become an area of increasing interest.

For the last few decades, PE sponsors have driven major consolidation across medicine and other professional services verticals. Substantial capital is now flowing into law firms and law-firm-adjacent assets, with PI practices attracting particular attention.

According to industry reports, investor dry powder has reached approximately $1.3 trillion globally, with 24 percent of that capital held for more than four years.

Sponsors under pressure to deploy aging capital are actively seeking new investment classes with attractive return profiles. PI law firms, an asset class with high margins and fragmented markets ripe for consolidation, fit that profile.

In this alert, we discuss recent transactions, evolving business models, and lessons from PE investment in medicine that may inform PE and PI firms considering strategic relationships.

Recent transactions

In January 2026, Uplift Investors launched Orion Legal MSO, with Dudley DeBosier Injury Lawyers – a 135-attorney PI firm with six offices across Louisiana and Texas – as its founding partner. Orion Legal operates as the group’s Managed Services Organization (MSO), providing nonlegal support services such as marketing, finance, technology, talent acquisition, and administrative infrastructure to add-on portfolio companies. These services enable attorneys to focus exclusively on client advocacy and legal outcomes. Since its founding partnership with Dudley DeBosier, Orion Legal has demonstrated that the MSO model is scalable, having closed multiple add-on transactions with law firms in other states.

Subsequently, other PE-backed platforms have emerged. In April 2026, an Arizona-based PI firm announced it had secured a strategic investment structured around business support services provided through its MSO in a deal with an enterprise value of nearly $500 million. Investment activity in law firms will likely accelerate given that several platforms are ready to invest.

Why PI firms appeal to PE

Characteristics of PI law firms attracting outside capital include:

• Financial: Diversified case inventories spanning auto accidents, premises liability, medical malpractice, and mass torts frequently generate growth, stable margins, and recurrent revenues. Furthermore, the contingency-fee model commonly found in PI firms produces outsized returns on resolutions.
  
  
• Market position: Leading PI firms utilize significant brand recognition, geographic defensibility, and scale advantages in advertising and lead generation that create meaningful barriers to entry. Smaller firms with less developed branding but strong outcomes may stand to benefit from PE investment and guidance in expanding their marketing presence.
  
  
• Competitive advantage: Differentiation in PI increasingly comes from technology-driven intake processes, data analytics for case valuation, and operational innovation that smaller competitors cannot replicate. PE can add value and optimize growth opportunities.
  
  
• Customer base: PI clients exhibit low concentration risk (thousands of individual matters) and, in the mass tort context, long duration and stickiness.
  
  
• Operational: Sponsors value firms with strong management teams willing to enter continuity agreements, systematized operations, and scalable infrastructure that reduce reliance on any single rainmaker.

Taken together, these factors indicate a compelling investment landscape: a fragmented, high-margin sector with significant operational upside and a large total addressable market amenable to platform-style roll-up strategies.

How PE invests in law firms

ABA Model Rule 5.4 and the MSO solution

ABA Model Rule 5.4, which has been adapted in some form by most United States jurisdictions, has long stood as a deterrent to outside investment in law firms. Model Rule 5.4 and its corresponding state rules generally prohibit lawyers and law firms from sharing legal fees with nonlawyers, forming partnerships with nonlawyers for the practice of law, permitting nonlawyers to direct or regulate a lawyer's professional judgment, and practicing in entities in which nonlawyers own an interest or exercise control over professional judgment.

Two principal models for law firms to align and partner with investors in a compliant manner have emerged: 1) the Alternative Business Structure (ABS) law firm model and 2) the MSO model. The ABS model has seen limited adoption, given its availability in only a handful of jurisdictions (e.g., Arizona; Utah; Washington, DC; and Puerto Rico). The MSO model, by contrast, can be implemented in virtually any state and has garnered further traction, given investor confidence in using a model that operates in a similar manner to how sponsors have effectively invested in other regulated professional services (e.g., medicine, dentistry, veterinary, engineering, and accounting).

When properly structured, the MSO model may permit investors to benefit economically from the law firm’s growth without impermissible fee-sharing; however, practitioners are encouraged to exercise caution. No MSO structure is automatically compliant, and the distinction between a permissible operational services arrangement and impermissible economic participation in legal fees can be difficult to discern. Fee structures may include fixed fees, cost-plus arrangements, separately priced service components, or operational performance incentives, but each must be evaluated against the specific jurisdiction’s rules.

To facilitate an MSO model, a PI law firm would typically undertake a corporate restructuring in which the nonlegal business functions are spun off into a newly formed separate legal entity (the MSO). The law firm would then enter into a business support arrangement with the MSO under which the MSO provides the law firm with a host of nonlegal services (e.g., technology, office space and equipment, lead generation, financial services, and nonlawyer personnel) in return for an arm’s-length, market-based service fee. Notably, the law firm is the entity that would remain ultimately responsible for all aspects of the practice of law, including client engagements, maintaining attorney-client privilege, conflicts management, the handling of trust accounts, and receipt of client fees.

By offloading operational complexity to a professionally managed services organization, attorneys can be free to focus on case strategy, client advocacy, and litigation outcomes. Representation of injured individuals under an MSO model may be backed by greater institutional resources than those typically available in a traditional solo or small firm.

Analogous transactions in medicine

PE’s path to law firms began with investments in medicine and the structural innovations they required (i.e., the development of the MSO model). The lessons from medicine offer a roadmap for PE and PI firms considering strategic relationships.

Medicine and healthcare: Structural precedent

Structurally, PE investment in medicine and the subsequent investment models that emerged are perhaps the most analogous to the PE trend with PI firms. For nearly three decades, investors have established alignment strategies with medical groups and healthcare professionals subject to the corporate practice of medicine rules and other regulations. DLA Piper has led hundreds of transactions with an aggregate enterprise value exceeding $100 billion in physician practice management, dental service organizations, and other health services.

Like in medicine, investors looking to align with personal injury law firms could potentially invite scrutiny if their deals are not properly structured. Well-positioned investors will grow and scale to a successful exit by engaging professional advisors with deep experience in heavily regulated industries, who can understand and foresee legal and ethical challenges and advise clients on the appropriate paths to meet their business goals.

Notably, PE and other investors cannot simply import an existing MSO template into law. Law firms are subject to Rule 5.4 and local professional responsibility rules that are often more restrictive and fragmented than the rules applicable to medicine.

However, mutually beneficial solutions are possible, even within a highly regulated space. Investors are expected to continue to seek exposure to professional services economics by isolating scalable business functions from protected professional judgment. Whether that model works in legal services will depend on the precision of the management services agreement, the independence and reasonableness of service-fee arrangements, and the operational discipline with which the parties preserve lawyer independence.

Optimizing value and assessing uncertainty

For PI firm principals considering a PE transaction, the dual challenge is maximizing enterprise value and navigating a regulatory landscape that remains unsettled.

Conveying scalability over individual reliance

A key lesson from healthcare is that investors pay premium multiples for platforms and systems, not solely individuals. Investments in local physician practices typically built around one or a few individual practitioners demonstrate that investors understand and are comfortable with the founder-centric dynamics common to PI law firms. However, when a firm’s current and future revenues depend solely on the personal relationships and reputations of a single founder or small group of rainmakers, investors may face significant key-person risk that depresses valuations and increases deal complexity.

The challenges of enforcing attorney noncompete covenants may also influence investor confidence in valuations. Firms that can demonstrate systematized intake, standardized case processing, technology-enabled workflows, and distributed management structures can earn meaningfully higher multiples.

For PI firms, this means showing that the firm’s marketing engine, case-management systems, settlement analytics, intake processes, and client-service infrastructure can function and grow independent of any one attorney, even the founding partner. Sponsors invest in the machine and its potential, not just the machinist.

EBITDA multiples and valuation benchmarks

Valuation in healthcare and professional services transactions is typically expressed as a multiple of adjusted earnings before interest, taxes, depreciation, and amortization (EBITDA).

Recent PE-backed transactions have closed at high-single-digit to double-digit EBITDA multiples, with platform acquisitions at the higher end and bolt-on acquisitions at lower levels.

PI law firms may expect that initial platform valuations will reflect both the firm’s standalone earnings profile and the credibility of its growth story, encompassing organic case-volume growth, geographic expansion, practice-area diversification, and a defined acquisition pipeline. Sell-side and buy-side quality of earnings analyses will be key, and firms are encouraged to prepare to distinguish reported, adjusted, and pro forma EBITDA clearly.

State-based resistance and regulatory uncertainty

PI firms partnering with PE must navigate a complex regulatory landscape. While properly structured MSOs may comply with Rule 5.4, several states have moved to restrict or regulate such investment, creating meaningful geographic risk for firms and investors. California, Colorado, and Illinois have adopted, or are considering, regulations that limit nonlawyer partnerships with, and ownership of, law firms. Firms and investors are therefore encouraged to evaluate regulatory risk on a state-by-state basis, with particular attention to states with high enforcement risk or where new legislation is pending.

Conclusion

PE capital is flowing into law firms, and well-positioned PI firms are likely the breakout asset class of 2026. Despite certain limitations, properly structured MSOs provide a viable solution to the regulatory and ethical obstacles surrounding law firms. Whether individual law firms will view the opportunity as worth pursuing remains to be seen.

Understanding risks, selecting the appropriate structure, engaging experienced advisors, navigating regulatory uncertainty, and optimizing value potential will determine deal appetite as the market expands.

Firms considering a potential transaction are encouraged to begin by evaluating their operational readiness; engaging a team of trusted advisors across legal, financial, tax, and technology disciplines; proving valuation potential; quantifying return-on-investment and capital gains opportunities; clarifying preferred investment partner characteristics; and ensuring internal alignment among firm leadership.
