Liberty Mutual vs Co-insurers: Legal Battle on Coverage Responsibilities

Liberty Mutual has initiated a federal lawsuit to compel two co-insurers to assume defense costs in a case stemming from a negligence claim involving a contractor and a parked truck.

Liberty Mutual's legal battle centers around an April 2023 incident in the Bronx, where a pedestrian sustained injuries involving a 2017 Western Star truck owned by JP Hogan Coring & Sawing Corporation. Liberty Mutual contends that the truck qualifies as a "covered auto" under Hogan's commercial auto policy. Currently, Liberty Mutual Fire Insurance Company defends El Sol, a contractor, and its employee named in the injured party's lawsuit. Liberty asserts that Crum & Forster Indemnity Company and Starr Indemnity & Liability Company should bear this responsibility.

Understanding the Insurance Dispute

At the core of this lawsuit is a contractual agreement stipulating that Hogan, subcontracted by El Sol for concrete services, add El Sol as an additional insured under a "primary, non-contributory" policy. Hogan's insurance, underwritten by Crum & Forster, includes a $1 million auto coverage limit, enhanced by Starr’s excess policy with a $5 million limit. Liberty Mutual argues that these terms make Crum & Forster the primary insurer responsible for covering defense costs, due to a blanket additional-insured endorsement.

The Contractual Interpretation

The controversy highlights the interpretation of additional-insured provisions, focusing on priority of coverage and contractual obligations. The contract allegedly requires a minimum of $5 million in "Comprehensive Automobile Liability" coverage, meticulously structured between primary and excess policies, to ensure El Sol's protection. Liberty Mutual claims that its policy should activate only after other policies are exhausted.

Legal Proceedings and Market Implications

Liberty Mutual first sought to transfer defense duties to Crum & Forster in August 2024, a request which was later denied by March 2026. Starr reportedly neglected to respond to a tender made in February 2026. The focus is whether Crum & Forster, prompted by policy language and a contractual obligation, must assume primary liability. Thus far, the court has not rendered a decision on Liberty Mutual's claims.

Implications for Insurance Professionals

  • Contractual Clarity: The case underscores the need for explicit contractual language regarding additional-insured coverage and priority structures.
  • Dispute Outcomes: Decisions could set precedents on the application of "primary, non-contributory" clauses in similar contractor-subcontractor relationships.
  • Risk Management: Insurers and policyholders need to assess the adequacy of their coverage and ensure adherence to contract stipulations to mitigate litigation risk.

The lawsuit brought by Liberty Mutual highlights the critical nature of precise contractual terms and policy endorsements in the realm of insurance coverage. As the proceedings unfold, insurance professionals should closely monitor the outcomes to better navigate complex coverage obligations in their contractual frameworks.
