A new endorsement from the Insurance Services Office (ISO) introduces a disclosure requirement that could reshape how litigation funding is handled in insurance claims. The endorsement mandates that policyholders pursuing coverage must disclose any third-party litigation funding agreements related to the claim or suit. The condition applies broadly and includes the obligation to reveal details such as the identity of funders, the scope of their involvement, and any financial interest or control they may exert over the litigation process.

According to National Law Review, the move reflects growing concern among insurers about the influence and potential risks posed by undisclosed funding arrangements. Insurers argue that such agreements can materially affect the dynamics of a claim, especially if the funder holds veto rights over settlements or expects a large portion of any recovery.

The endorsement gives insurers a clearer path to scrutinize and potentially contest claims that are influenced by outside funding, thereby shifting how policyholders must prepare their claims and structure litigation financing.

More broadly, this endorsement may signal a new phase in the regulatory landscape for litigation finance—one in which transparency becomes not just a courtroom issue, but a contractual one as well.

A major ruling by the Competition Appeal Tribunal (CAT) has delivered a setback to litigation funder Innsworth Advisors, which unsuccessfully opposed the settlement in the landmark Mastercard consumer class action. Innsworth has been ordered to pay the additional legal costs incurred by class representative Walter Merricks, marking a clear message from the tribunal on the risks of funder-led challenges to settlements.

As reported in the Law Gazette, the underlying class action, one of the largest in UK legal history, involved claims that Mastercard’s interchange fees resulted in inflated prices passed on to nearly 46 million consumers. The case was brought under the collective proceedings regime, and a proposed £200 million settlement was ultimately agreed between the class representative and Mastercard. Innsworth, a funder involved in backing the litigation, challenged the terms of the settlement, arguing that it was disproportionately low given the scope and scale of the claim.

The CAT, however, rejected Innsworth’s arguments and sided with Merricks, concluding that the settlement was reasonable and had been reached through an appropriate process. Moreover, the tribunal found that Innsworth’s intervention had caused additional work and expense for the class representative team—justifying the imposition of cost penalties on the funder.

For the litigation funding sector, this ruling is a cautionary tale. It underscores the importance of funder alignment with claimants throughout the litigation and settlement process, particularly in collective actions where public interest and judicial scrutiny are high.
