Subrogation refers to an insurance company's attempt to recoup expenses for a claim it paid when it's determined that another party is responsible for paying at least a portion of the claim. In law, it is referred to as the "transfer of right of the creditor to the third party who pays the debt of the debtor." Subrogation is an equitable remedy and is subject to all the usual limitations that apply to equitable remedies. Although the basic concept is relatively straightforward, subrogation is considered to be a highly technical area of the law. However, it is an area in which FTC can ably assist with reports and expert testimony.
