Insurance Litigation

Weil has in-depth knowledge of the complex issues facing the insurance industry. Comprising lawyers located in offices around the U.S., our Insurance Litigation practice is well-equipped to represent the world’s most sophisticated insurance and reinsurance companies on all manner of disputes.
Our blend of litigation and arbitration experience brings expertise to all sides of complex disputes, including successfully defending clients against private, government, and class action suits, and representing plaintiffs in major cases of first impression.

We have achieved successful results for clients at every phase of the litigation process in both trial and appellate courts, including obtaining dismissals of class action and other complaints, defeating class certification, winning summary judgment motions, prevailing at trial or on appeal, and obtaining highly favorable settlements.

We have significant experience in handling internal investigations and in dealing with insurance regulators, including assisting clients with investigations by Congressional committees and state attorneys general.

We also have significant experience in handling complex reinsurance arbitrations, representing or being adverse to some of the largest companies in the world.
