- A quasi contract is not a real contract
- It is not based on express or implied intentions of the parties
- It is not based upon the offer and acceptance rule
- It lacks one of the essentials of a valid contract i.e. consent of the parties
- It does not arise from any formal agreement but is imposed by law
- The right under it is available against specific person(s) and not against the world
- A suit for its breach may be filed in the same way as in case of a general contract.
Note: In English law, quasi contracts are also known as constructive contracts.
Shiva pays some money to Ganesh by mistake. It is actually due to Parvathi. Ganesh must refund the money to Shiva.
