One of the essential conditions for the conclusion of the contract is that it must not be void. Section 10 of the Indian Contract Act states that “all agreements are contracts. which are not expressly cancelled”. A contract can be signed for several reasons, for example: Lowe v. Peers set a precedent in the Marriage Limitation Act. In this case, the defendant argued that if he married someone other than the plaintiff, he would give her £1,000 within three months of her marriage. Such an agreement is inconclusive. An agreement is invalid when it prevents a person from asserting his contractual rights through ordinary legal proceedings or when he limits the period within which he can assert his rights.
