Cozen O'Connor is the world's leading subrogation and recovery law firm. We founded our subrogation and recovery practice in 1970. Auto insurance subrogation is a process where your insurance company compensates you first, then seeks reimbursement from the at-fault party to an accident. Our attorneys have successfully handled subrogation claims for a variety of insurers, both international and domestic, both pre-suit and in litigation. Subrogation is a common process in which your insurance company gives you money for your damages upfront, then goes up against the defendant for reimbursement. It is important, therefore, to choose your recovery method wisely before you file. You have no legal obligations to respond to a subrogation letter.
