Section 51 of the Indian Contract Act, 1872: Reciprocal Promises and Readiness to Perform
Section 51 deals with contracts containing reciprocal promises that are to be performed simultaneously. It protects a promisor from having to perform where the other party is not ready and willing to perform the corresponding promise.
What does Section 51 provide?
Where a contract consists of reciprocal promises that must be performed simultaneously, a promisor is not required to perform unless the promisee is ready and willing to perform the reciprocal promise.
In practical terms, neither party can ordinarily insist on simultaneous performance by the other while remaining unprepared or unwilling to perform his or her own corresponding obligation. The provision therefore links the duty of each party to the other party's readiness and willingness where the agreed performances are concurrent.
Meaning of reciprocal promises
Section 2(f) of the Indian Contract Act, 1872 defines promises that form the consideration or part of the consideration for each other as reciprocal promises. Section 51 applies to the particular situation in which those reciprocal promises are to be performed at the same time.
Essential requirements of Section 51
For Section 51 to apply, the contract must contain reciprocal promises, the relevant promises must be intended for simultaneous performance, and the party demanding performance must be ready and willing to perform the corresponding obligation. Whether obligations are truly simultaneous depends on the terms and nature of the contract.
Statutory illustrations
Delivery of goods against payment
If A agrees to deliver goods to B and B must pay on delivery, A need not deliver unless B is ready and willing to pay on delivery. Correspondingly, B need not pay unless A is ready and willing to deliver the goods against payment.
Delivery with first instalment payable on delivery
If A agrees to deliver goods to B for a price payable by instalments and the first instalment falls due on delivery, A need not deliver unless B is ready and willing to pay that instalment. B likewise need not pay the first instalment unless A is ready and willing to deliver the goods upon payment.
How Section 51 works with Sections 52 to 54
Section 51 concerns simultaneous reciprocal performance. Section 52 addresses the order in which reciprocal promises are to be performed. Section 53 deals with prevention of performance by one party, while Section 54 deals with default in performing a promise that should be performed first.
Practical effect
The section is especially relevant to transactions structured as concurrent exchanges, such as delivery against payment. A party relying on Section 51 should be able to establish readiness and willingness to carry out the reciprocal obligation in accordance with the contract. The precise rights of the parties will depend on the contractual terms and the facts of the transaction.
