Recent judicial rulings and market commentary have thrust the LEG-3 defects exclusion into the spotlight: courts in the United States have interpreted the clause in ways that preserve cover for certain “damage” caused by defective work, generating surprise and concern among carriers that relied on LEG-3 to limit exposure to improvement costs. These decisions — together with public write-ups and market analysis — have exposed ambiguities in the drafting of LEG-3 (notably its mixing of causation language with property-condition language) and have prompted calls for redrafting or clearer guidance from market bodies. The result is a practical uncertainty across underwriting desks and renewal negotiations: some insurers are tightening capacity and terms, while brokers and buyers face inconsistent interpretations of what is and is not excluded under standard LEG-3 wordings.

For insurers, brokers and insurance buyers the stakes are high. LEG-3’s present ambiguity affects indemnity exposure, reserve setting, pricing and the defensibility of claims on major construction programmes; for buyers it can mean unanticipated gaps or sudden increases in cost of cover, or protracted disputes at claim time. This panel will interrogate “the 2026 state of play” for LEG-3: what (if anything) has changed in the latest wordings, how the market is (or isn’t) converging on interpretation and what pragmatic risk-transfer, contractual and on-site strategies both carriers and buyers should adopt now to manage uncertainty. Attendees will leave with a clearer sense of the legal fault lines, practical underwriting implications and immediate steps to reduce exposure and strengthen insurability.
