Insurance Litigation
Allen & Overy’s international team of insurance litigation and arbitration lawyers is renowned for its legal and tactical expertise, depth of resource and clout in resolving coverage disputes.
We specialise in advising on the resolution of large and difficult claims and in the defence of claims against companies and their directors that are insured under all types of liability insurance policies.
A&O is ideally positioned to take on cross-border cases given our extensive office network covering the key insurance markets in Western Europe, Asia and the U.S. We are world leaders in the use of arbitration, typically the preferred form of dispute resolution in insurance policies.
Our insurance cases frequently involve catastrophic losses, difficult coverage and loss allocation issues, often with complex underlying international litigation and arbitration. We are experts in:
- professional indemnity/civil liability
- product liability, toxic tort liabilities and product withdrawals (particularly in the pharmaceutical context)
- environmental, nuisance, property damage and business interruption claims
- directors and officers (D&O) liabilities, often connected to U.S. securities class actions
- catastrophe financial risk
- credit insurance
- crime policy/bankers blanket bond
- regulatory risk and political risk
- distressed captives and insolvent insurers
- insurance and reinsurance advisory services
