***
The right of an insurer which has paid a claim under a policy to step into the shoes of the insured so as to exercise in his name all rights he might have with regard to the recovery of the loss which was the subject of the relevant claim paid under the policy up to the amount of that paid claim. The insurer’s subrogation rights may be qualified in the policy. In the context of insurance subrogation is a feature of the principle of indemnity and therefore only applies to contracts of indemnity so that it does not apply to life assurance or personal accident policies. It is intended to prevent an insured recovering more than the indemnity he receives under his insurance (where that represents the full amount of his loss) and enables his insurer to recover or reduce its loss.
***
The right of one party who has paid for the loss of a second party to obtain recompense from the third party who is responsible for the loss. For example, an insurance company becomes subrogated to the rights of its insured to the extent of the insurer’s payment for collision damage caused by the negligence of the other driver. Often explained as stepping into the shoes of another the insurer steps into the shoes of the insured and collects what they had paid to the insured from the at fault party.
