Mr. Costigan’s primary area of concentration is reinsurance and insurance coverage disputes involving workers compensation, property and casualty, and professional liability lines of business.

His reinsurance coverage experience includes representation of reinsurers and cedents in resolving disputes over the cession of workers’ compensation losses, allocation of continuing losses, number of occurrences, pre-hearing security, follow the fortunes doctrine, and coverage of declaratory judgment expenses. He has conducted depositions or appeared in legal proceedings in England, France, Bermuda, and Switzerland in connection with international arbitrations.

Mr. Costigan’s insurance coverage experience involves representation of insurers with regard to a wide array of issues arising from workers compensation, CGL, umbrella, marine bumbershoot, and professional liability insurance policies, including allocation of asbestos, talc, and environmental losses, liability to additional insureds, date of loss, related claims, and potential bad faith exposure.

He also has experience with insurer insolvency issues, having represented the liquidators of insurers or reinsurers domiciled in New York, New Hampshire, Kentucky, and New Jersey. He successfully assisted liquidators in prevailing on arguments that the liquidation process alters the normal application of law to an insurance or reinsurance contract in material ways, e.g., that an otherwise appropriate “all sums” recovery is impermissible against an insolvent insurer and a state law voiding a reinsurer’s pre-insolvency arbitration agreement is preserved by the McCarren-Ferguson Act from pre-emption by the Federal Arbitration Act.

Mr. Costigan has handled a broad array of litigation matters, including patent infringement, copyright infringement, antitrust, employment, and intellectual property license disputes. He has represented several clients in the negotiation and performance of licensing agreements, founder agreements, scientific advisory board agreements and consulting agreements. He has also advised clients with respect to business acquisitions and negotiated the purchase and sale of businesses.

Mr. Costigan received his B.A. from St. Joseph’s University and his J.D. from Fordham University School of Law.
