The Essentials of a Valid Contract: A Comprehensive Guide with Case Laws and Illustrations

Read 5 minutes

Contracts play a pivotal role in the legal and business world. Governed by the Indian Contract Act, 1872, a contract is defined under Section 2(h) as an “agreement enforceable by law.” But for an agreement to transform into a valid contract, it must meet specific criteria. Let’s break down these essential elements with relevant case laws, sections, and illustrations.


1. Offer and Acceptance

The foundation of any contract is an offer by one party and the acceptance by the other. According to Section 2(a), an offer is a proposal made by one party to another, and once it is accepted (Section 2(b)), it becomes an agreement.

  • Case Law: Carlill v. Carbolic Smoke Ball Co. (1893)
    In this case, the defendant company made an offer to the public that they would pay £100 to anyone who contracted the flu after using their product. When Mrs. Carlill accepted the offer by purchasing and using the product as instructed, the court held that a valid contract existed upon her acceptance.
  • Illustration: A offers to sell his bike to B for ₹30,000. B agrees to buy it at that price. The offer and acceptance are clear, thus forming an agreement.

For a contract to be enforceable, both parties must have the intention to create legal relations. This element is often missing in social and domestic agreements.

  • Case Law: Balfour v. Balfour (1919)
    In this case, a husband promised to pay his wife an allowance while he was abroad. The court ruled that there was no intention to create legal relations, as the agreement was domestic in nature.
  • Relevant Section: This concept is embedded in the general principles of contract law but not explicitly stated in the Indian Contract Act.
  • Illustration: A father promises to give his daughter ₹5,000 every month, but later stops. This agreement lacks legal intent and thus cannot be enforced.

3. Lawful Consideration

Section 2(d) defines consideration as something in return (quid pro quo). A contract is valid only if it involves lawful consideration.

  • Case Law: Currie v. Misa (1875)
    In this case, it was held that consideration could include a benefit to the promisor or a detriment to the promisee. Without consideration, a contract is invalid unless it falls under specific exceptions (like natural love and affection).
  • Relevant Section: Section 10 of the Indian Contract Act stipulates that an agreement is valid if it is made for lawful consideration.
  • Illustration: A agrees to sell his laptop to B for ₹20,000. B’s payment of ₹20,000 is the consideration for A’s promise to transfer the laptop.

4. Capacity to Contract

As per Section 11 of the Indian Contract Act, the parties to a contract must be competent, meaning they should be of sound mind, of the age of majority (18 years or older), and not disqualified by law.

  • Case Law: Mohori Bibee v. Dharmodas Ghose (1903)
    In this case, a minor entered into a mortgage agreement, and the Privy Council held that the contract was void because the minor lacked the capacity to contract.
  • Relevant Section: Section 11 explicitly lays down the rules regarding competency.
  • Illustration: A 16-year-old boy agrees to sell his bike to B for ₹15,000. Since A is a minor, the contract is void.

For an agreement to be valid, it must be entered into with the free consent of the parties, as per Section 13. Consent is said to be free when it is not caused by coercion (Section 15), undue influence (Section 16), fraud (Section 17), misrepresentation (Section 18), or mistake (Section 20-22).

  • Case Law: Ranganayakamma v. Alwar Setti (1889)
    In this case, a widow was forced to adopt a child under threat, and the court held that the consent was obtained under coercion, making the agreement voidable.
  • Relevant Section: Section 14 states that consent is free when it is not caused by coercion, undue influence, fraud, misrepresentation, or mistake.
  • Illustration: A threatens to harm B unless B agrees to sell his house to A. Here, B’s consent is not free, and the contract is voidable.

6. Lawful Object

The object of the contract must be lawful. Section 23 of the Indian Contract Act specifies that a contract will be void if its object is illegal, immoral, or opposed to public policy.

  • Case Law: Gherulal Parakh v. Mahadeodas Maiya (1959)
    The court held that an agreement to share profits from illegal betting activities was void, as its object was unlawful.
  • Relevant Section: Section 23 deals with the lawfulness of the object and consideration.
  • Illustration: A agrees to sell weapons to B for use in a robbery. This agreement is void as its object is unlawful.

7. Certainty of Terms

The terms of the contract must be clear and certain. Section 29 of the Indian Contract Act states that agreements that are vague and uncertain cannot be enforced.

  • Case Law: Scammell v. Ouston (1941)
    In this case, the court held that an agreement to purchase a lorry on “hire-purchase terms” was too vague, as the terms were never clarified.
  • Relevant Section: Section 29 declares that agreements whose terms are uncertain are void.
  • Illustration: A agrees to sell B “a car” without specifying which one. This agreement is void for uncertainty.

8. Possibility of Performance

The act agreed upon must be possible to perform. Section 56 of the Indian Contract Act renders agreements to do impossible acts void.

  • Case Law: Satyabrata Ghose v. Mugneeram Bangur (1954)
    In this case, the Supreme Court ruled that if the performance of a contract becomes impossible due to unforeseen circumstances, the contract is void.
  • Relevant Section: Section 56 covers the doctrine of frustration and impossibility of performance.
  • Illustration: A agrees to sell his house to B, but before the sale is complete, the house is destroyed by an earthquake. The contract is void as the performance has become impossible.

9. Not Expressly Declared Void

An agreement must not be one that is expressly declared void by law. Sections 24-30 list specific agreements that are void, such as agreements in restraint of trade (Section 27), marriage (Section 26), or legal proceedings (Section 28).

  • Case Law: Madhub Chander v. Raj Kumar (1874)
    In this case, the court ruled that an agreement restraining one party from carrying out a lawful profession or business was void under Section 27.
  • Relevant Section: Sections 24-30 declare certain types of agreements as void.
  • Illustration: A promises not to open a business in his city for five years in exchange for ₹50,000 from B. This agreement is void as it is a restraint of trade under Section 27.

Conclusion

The Indian Contract Act, 1872, ensures that only agreements that fulfill these essential elements are legally enforceable. By ensuring clarity, legality, and fairness in contractual obligations, these provisions protect the interests of all parties involved in a contract.
