Explanation: Vested right could be regarded as claims enforceable under the law. The are basic and absolute rights which an individual is entitled to, either by accrual or that which has been amassed or granted to an individual. Vested rights cannot be stripped off by a third party even though the individual may only be entitled to such right in the future such as retirement pay.

The retirement pay of employees cannot be stripped off them even by their employer as it is an enforceable claim or right which has been in agreement since taking up the job that after certain years of service, such employee is entitled to a future retirement pay.
