Sean Hanifin counsels and represents insurers in insurance coverage matters including excess judgment and “bad faith” claims, coverage allocation matters, and reinsurance. His practice is not geographically limited, as he has appeared in trial and appellate courts in more than forty states.

Sean’s general liability experience includes addressing intellectual property claims under personal and advertising injury coverages; mass tort claims including asbestos, food borne illness, and pharmaceutical claims (e.g., ephedra, Fen-Phen, and PPA); railroad claims; liquor liability claims; construction defect claims; structure collapses and catastrophic fires (including the MGM Grand Hotel, Las Vegas Hilton, DuPont Plaza Hotel, and Station Nightclub fires).

Sean has resolved both coverage disputes and underlying claims in a wide range of professional liability areas, including architect and engineering design, real estate agents, insurance agents and captive insurance managers, title insurance agents, directors and officers, and healthcare professionals and organizations, including managed health care matters and medical device matters. He has served since 1992 as the national claims counsel for the Title Industry Assurance Company, RRG, a risk retention group formed by the American Land Title Association. Acting on behalf of TIAC and other insurers, he has assisted in the resolution of more than 2,700 title agent, abstracter, and escrow agent professional liability claims.

Sean assists insurers in policy and endorsement drafting and in resolution of disputes that involve alternative risk structures including retrospectively rated coverages, captive insurance, and complex fronting arrangements and reinsurance structures. He has performed reserve adequacy studies in a range of areas, including employment practices, title insurance, liquor liability, and design professionals.

Sean is a contributing author to Law and Practice of Insurance Coverage Litigation (West Publishing), a fellow of the American College of Coverage Counsel, and a member of the American Land Title Association.
