The new entrant at the eye of the storm
One firm generating a significant amount of litigation in 2025 was Howden US, the American retail broking operation that London-based Howden launched in August of that year. Within months of opening its doors, it was facing lawsuits from Marsh, Aon, Willis Towers Watson, Brown & Brown, and Alliant – five separate actions, each telling a version of the same story.
