Growth and Challenges in Legal Professional Liability Insurance

Insurers in the legal professional liability (LPL) sector have experienced substantial growth in policyholders' surplus over the past five years, according to a report by AM Best. Despite this increase in surplus, premiums within this niche have seen only minimal growth during the same period. The report, titled “Specialty Legal Professional Liability Insurers Continue to Grow, Despite Varied Performance,” highlights challenges facing law firms, including a litigious environment, third-party litigation financing, and larger court settlements.

The report focuses on a composite group of 16 insurers primarily serving the LPL market, noting that limited geographic reach has constrained premium growth. The performance of these insurers has varied since the COVID-19 pandemic, with the LPL composite's operating ratio often outperforming the commercial casualty composite. In 2024, for instance, the LPL composite reported an operating ratio of 58.7, compared to 84.7 for commercial casualty insurers.

Since 2020, the LPL segment has demonstrated moderate year-over-year premium growth, primarily in the low single-digit range annually. Total direct premium written increased by over 18% between 2020 and 2025, compared to less than 1% growth in the previous five-year period. Rate increases have remained modest, mainly single-digit, as LPL insurers encounter competition from major carriers like Chubb and AIG. This competitive landscape requires innovation in product offerings and high levels of customer service to retain market positions.

David Blades, Associate Director of Industry Research and Analytics at AM Best, highlights the LPL market's health despite competitive pressures and challenges including fraudulent claims and cybersecurity threats. Effective risk management is critical to sustain market viability amid these issues.

Social inflation has led to higher loss adjustment expenses for LPL insurers compared to their commercial casualty peers over the past five years. The claims-made basis of LPL coverage contributes to these expenses. Although claim frequency has remained stable, severity has increased due to rising defense costs and more frequent high-value claims, pushing the industry towards a hardened rate environment since 2020. This rate adjustment aligns with inflationary pressures linked to the pandemic.

Emerging risks in areas such as artificial intelligence, cybersecurity, and increasing regulatory scrutiny necessitate higher premiums for LPL coverage to adequately protect law firms, notes Dylan Catania, Associate Analyst at AM Best.
