When the subrogation process has the status set to closed, it means that the insurance company either failed or successfully managed to get reimbursement from the at-fault party's insurance company. You can find out your subrogation status and additional details about this process by contacting your representative.
Subrogation is the process that allows your car insurance company to recoup losses from the at-fault driver's insurer for expenses they incurred after paying out a car accident claim. This process allows insurers to compensate you for your accident before determining who was at-fault for the crash, which can sometimes take a long time.
