Commercial liability insurers are escalating their long-running dispute with the litigation funding industry by introducing policy language that could require insured companies to disclose third-party funding arrangements. The move reflects mounting concern among insurers that litigation finance is contributing to rising claim costs and reshaping litigation dynamics in ways carriers struggle to underwrite or control.

An article in Bloomberg Law reports that the Insurance Services Office, a Verisk Analytics unit that develops standard insurance policy language, has drafted an optional provision that would compel policyholders to reveal whether litigation funders or law firms with a financial stake are backing claims against insured defendants. While adoption of the provision would be voluntary, insurers could begin incorporating it into commercial liability policies as early as 2026.

The proposed disclosure requirement is part of a broader push by insurers to gain greater visibility into litigation funding arrangements, which they argue can encourage more aggressive claims strategies and higher settlement demands, particularly in mass tort and complex commercial litigation. Insurers have increasingly linked these trends to what they describe as social inflation, a term used to capture rising jury awards and litigation costs that outpace economic inflation.

For policyholders, the new language could introduce additional compliance obligations and strategic considerations. Companies that rely on litigation funding, whether directly or through counterparties, may be forced to weigh the benefits of financing against potential coverage implications.

Litigation funders and law firms are watching developments closely. Funding agreements are typically treated as confidential, and mandatory disclosure to insurers could raise concerns about privilege, work product protections, and competitive sensitivity. At the same time, insurers have been criticized for opposing litigation finance while also exploring their own litigation-related investment products, highlighting tensions within the market.

If widely adopted, insurer-driven disclosure requirements could represent a meaningful shift in how litigation funding intersects with insurance. The development underscores the growing influence of insurers in shaping transparency expectations and suggests that litigation funders may increasingly find themselves drawn into coverage debates that extend well beyond the courtroom.

US-based litigation funder Diamond McCarthy has agreed to back a high-stakes investment treaty claim brought by Lansdowne Oil and Gas against the Irish state, with the claim reportedly valued at up to $100 million. The dispute arises from Ireland’s policy shift away from offshore oil and gas development, which Lansdowne argues has effectively wiped out the value of its investment in the Barryroe offshore oil field.

According to NewsFile, Lansdowne Oil and Gas, a small exploration company listed in London and Dublin, is pursuing arbitration against Ireland under the Energy Charter Treaty. The company alleges that Ireland’s 2021 decision to halt new licences for offshore oil and gas exploration, followed by regulatory actions affecting existing projects, breached treaty protections afforded to foreign investors. Lansdowne contends that these measures frustrated legitimate expectations and amounted to unfair and inequitable treatment under international law.

Diamond McCarthy’s involvement brings significant financial firepower to a claim that would otherwise be difficult for a junior energy company to pursue. The funder will cover legal and arbitration costs in exchange for a share of any recovery, allowing Lansdowne to advance the case without bearing the full financial risk. The arbitration is expected to be conducted under international investment dispute mechanisms, with proceedings likely to take several years.

Ireland has previously defended its policy changes as part of a broader climate strategy aimed at reducing fossil fuel dependence and meeting emissions targets. Government representatives have indicated that the state will robustly contest the claim, arguing that the measures were lawful, proportionate, and applied in the public interest. Ireland is also in the process of withdrawing from the Energy Charter Treaty, although existing investments may remain protected for a period under sunset provisions.
