US personal injury law firms are leading a push to open the doors to private equity investment in the legal sector, even in the face of long-standing regulatory opposition to outside ownership of law practices.

According to the Financial Times, a growing number of US firms that built their practices around high-volume, billboard-driven mass tort and injury representation are quietly exploring capital injections from private equity firms. The motivation is fast growth, increased leverage, and the ability to scale operations rapidly, something traditional partner-owned firms have found difficult in a consolidating market.

The move represents a departure from the conventional owner-operator model historically favored by the legal profession, where practicing attorneys hold equity in their firms. Private capital could provide aggressive funding for marketing, case acquisition, litigation infrastructure, and operational expansion, enabling firms to ramp up nationwide acquisition of cases. Critics, however, warn that outside investors prioritizing returns could create pressure to maximize volume over client outcomes.

Private equity’s entrance into legal services is not entirely new, but the aggressive push by personal injury firms may mark a tipping point. If regulators and bar associations ease restrictions on non-lawyer ownership or passive investment, this could fundamentally reshape how US law firms are structured and financed.

For the legal funding industry, this trend signals a potential increase in demand for third-party litigation financing and capital partners. As firms leverage outside investments for growth and case volume, funding providers may find new opportunities or face increased competition.

A high-stakes dispute between insurers AmTrust and Sompo is unfolding in UK court, centered on a failed litigation funding scheme that left AmTrust facing an estimated £59 million in losses. At the heart of the case is whether Sompo, as the professional indemnity insurer of two defunct law firms, Pure Legal and HSS, is liable for the damages stemming from their alleged misconduct in the operation of the scheme.

An article in Law360 reports that AmTrust had insured the litigation funding program and is now pursuing Sompo for reimbursement, arguing that the liabilities incurred by Pure and HSS are covered under Sompo’s policies. The two law firms entered administration, leaving AmTrust to shoulder the financial burden. AmTrust contends that the firms breached their professional duties, triggering coverage under the indemnity policies.

Sompo, however, disputes both the factual and legal underpinnings of the claim. The insurer denies that any breach occurred and further argues that even if the law firms had acted improperly, their conduct would not be covered under the terms of the policies issued.

This case follows AmTrust’s recent resolution of a parallel legal battle with Novitas, another financial party entangled in the scheme. That settlement narrows the current dispute to AmTrust’s claim against Sompo.
