Insurance and reinsurance litigation

Within: Insurance and reinsurance litigation

Berwin Leighton Paisner and Bryan Cave merged to form Bryan Cave Leighton Paisner LLP in April 2018, giving clients access to a ‘very professional service’. The team handles major insurance coverage disputes, usually international in nature and often with an unusual element, for blue-chip clients such as AIG, Munich Re and Travelers; it recently advised the latter in relation to a disputed insurance claim in excess of £1m. Another highlight for the practice, which is particularly known for its ‘good knowledge of D&O defence’, was Anthony Lennox defending the former finance director of a large refrigeration business that became insolvent, assisted by Kelly Jones. Lennox, who heads the firm's insurance and reinsurance disputes practice, has 25 years’ experience of (re)insurance litigation and arbitration. Another notable attraction for clients is head of insurance Jonathan Sacher, who has not lost a reinsurance case in over 20 years.
