"Subrogation" refers to the act of one person or party standing in the place of another person or party. Contractual provisions which would deny the insured complete recovery for a loss are unenforceable. Subrogation is the right of an insurer to pursue the party that caused the loss to the insured in an attempt to recover funds paid in the claim. The purpose of subrogation is to prevent an insurance company from paying for medical costs and other losses when it is not obligated to do so. Subrogation is a civil procedure in law. An attorney can help you further protect your financial recovery.
