Stewarts Law LLP’s litigation-only policyholder disputes practice focuses solely on high-value and complex coverage disputes for policyholders, combining ‘true deep technical expertise and commercial understanding’ to achieve its reputation as heavyweight policyholder advocates, particularly in the COVID-19-related business interruption sphere. The practice is bolstered by its experienced and dedicated team of insurance coverage experts led by ’outstanding’ Aaron Le Marquer, who, alongside extensive COVID-19-related business interruption work, is experienced in all lines of commercial insurance, with a particular focus on high-value and complex disputes, often with a cross-border element. Chloe Derrick has a wealth of experience in a broad range of insurance coverage disputes, with strong multi-jurisdiction experience. The practice benefits from the recent promotion of James Breese to partner, who has acted on a number of business interruption cases and significant political risk insurance disputes.
