Jon Neumann is an experienced trial lawyer representing insurers and other clients in complex disputes in federal and state courts, as well as in varied domestic and international arbitral forums. Jon represents health insurers in health-benefits litigation and other high-stakes disputes with health care providers. He also regularly advises clients on contract and extra-contractual claims, business torts, and real estate and other commercial matters. Additionally, Jon provides coverage advice and helps insurers in the defense of arbitrations and civil litigation including claims relating to breach of contract, breach of fiduciary duty, bad faith, business torts, insurance coverage, punitive damages, and state consumer-protection statutes.

Jon’s health care practice is focused on managed care and employee benefits matters. He has represented managed care entities and administrators in virtually all aspects of insurance arbitration and litigation including ERISA, contractual and extra-contractual disputes with providers and hospitals, prompt pay litigation, insurance fraud, and medical liability claims.

In conjunction with his insurance coverage and bad faith practice, Jon guides insurers through the legal aspects of complex coverage disputes, including class actions involving institutional bad faith claims, national insurance claim-handling programs, and computerized evaluation tools. He provides coordinating counsel services for the national defense of institutional claim-handling programs and offers counseling services to help insurers avoid litigation and minimize bad-faith exposure. Jon also advises on the efficient and fair management of claim-handling operations.

Jon’s reinsurance practice is focused on helping reinsurers and retrocessionaires strategically approach complex disputes involving issues such as actuarial modeling and other damage assessments, ratification, rescission, allocation, underwriting, the duty of utmost good faith, mergers and acquisitions, the purchase and sale of blocks of business, and other controversies related to the retrocession of risk through reinsurance treaties and other risk-transfer arrangements.
