What is a CONTRACT?

• A CONTRACT

According to Section 2(h) of Indian Contract Act 1872 "An agreement enforceable by law is a contract". It means a contract has two basic characteristics:

1. An Agreement: According to Section 2(e) of Indian Contract Act 1872 "Every promise or set of promises forming consideration for each other is an agreement".

Example: A offers to sell his car to B in Rs. 500000/-. Here,  A is a offerer and B is accepter.
2. Intention to create legal relationship: There must be some intention to create legal relationship.
Example: X invite his friend B on dinner, B does not reach. Here,  X cannot go to the court against B to recover his loss because such agreement doesn't create any legal relationship between them.

7. Possibility of performance: There should be possibility of performing the obligation of the contract.
Example: A agrees with B to discover a treasure by magic on the payment of Rs. 100000/- by B to A. This is a case of impossibility of performance, hence,  unenforceable by the law.
8. Agreement should not be declared as void:
