Q: What is doctrine of restitution ?

Ans: Section 65 of the Indian contract act 1872 mainly deals with the doctrine of restitution and it relates to the obligation of the person who has received some advantage under void agreement or contract. This section starts from the very basis that there being an agreement or contract and if there was no agreement or contract then the doctrine of restitution cannot come into play. This doctrine is based on a very common rule of consideration which means that a person pays consideration only when he gets something in return.
