QUESTION: Explain the different types of contract that can be formed under the Indian Contract Act, 1872.



A contract is a legally binding agreement which recognizes and governs the rights and duties of the parties to the agreement. A contract is legally enforceable as it meets the requirements and approval of the law.

According To Section 2(h) Of The Indian Contract Act 1872

“An agreement enforceable by law is a contract.”


The following are the various types of Contract:

EXAMPLE: Amar said to Akbar, Will you buy my watch for ₹500. Akbar replies, I am ready to buy. This is an express contract made orally.

  • IMPLIED/TACIT CONTRACT: The contract is an implied contract in which a proposal or acceptance is made other than words spoken or written.

These contracts are not created by words, either spoken or written but by an act or conduct of parties.

EXAMPLE:A, a coolie in uniform take up the luggage of B at Railway Station as B allows him to do so. The law implies that B will have to pay for the services of A. This is an Implied contract.

  • QUASI CONTRACT: These are the contracts which are created by the law and not by the words or conduct of the parties. This contract is based on the principle that a person shall not be allowed to enrich himself at the expense of another party.

Under Section 71 of Indian Contract Act 1872: In case of finder of lost goods.

Under Section 72 of Indian Contract Act 1872: When payment is made by mistake and goods are delivered by mistake.


In this case, A’s husband becomes no more. She is very poor and therefore not capable of meeting the cost of cremation. B, one of her relatives, understands her position and spends his own money for cremation. It is done so without A’s request. Afterwards B claims his amount from A where A refuses to pay. Here court applies Section 68 and creates a Quasi Contract between them.
