Cozen O'Connor is the world's leading subrogation and recovery law firm. We founded our subrogation and recovery practice in 1970.The Anti-Subrogation Rule ("ASR") is a common law defense to subrogation. It is only when the plaintiff's recovery exceeds the sum total of the plaintiff's damages that the right of subrogation arises. Our subrogation attorneys are licensed in Illinois, Indiana, Kentucky, Michigan, New Jersey, Ohio, and Pennsylvania. The time needed for recovery varies with each claim and could take up to one year or longer. What do I need to do during the deductible recovery process? In Illinois, if no suit has been filed, the claim must be filed two years from date of contribution plaintiff's payment. An insurer has no right of subrogation against its own insured for claims arising from the very risk for which the insured was covered. The claims file should contain all correspondence, notes and other material relevant to the claim.
