Quick Answer

A contract is a legally enforceable agreement. Under the Indian Contract Act, 1872, a valid contract requires an offer and acceptance, lawful consideration, free consent, competent parties, and a lawful object. In the US, contract law splits between common law (services, real estate) and UCC Article 2 (sale of goods). The critical difference is that a minor's contract is void ab initio in India but only voidable at the minor's option in the US. When a contract is breached, courts award expectation damages as the default remedy; specific performance is reserved for unique goods or land where money cannot adequately compensate.

Indian Contract Law

The Indian Contract Act, 1872

Indian contract law is primarily governed by the Indian Contract Act, 1872 — one of the oldest commercial statutes still in force. A contract is defined under Section 2(h) as:

"An agreement enforceable by law."

Section 2(e): An agreement = offer + acceptance. Not every agreement is a contract — a family dinner plan is an agreement, but not a contract.

Essential Elements of a Valid Contract (India)

For a contract to be valid and enforceable under Indian law, all of the following must be present:

ElementSectionExplanation
Offer and Acceptance2(a), 2(b)Definite proposal + unconditional acceptance
Lawful Consideration2(d), 25Something of value moving from the promisee at the desire of the promisor
Capacity11–12Parties must be of majority age, sound mind, not disqualified by law
Free Consent14–22Free from coercion, undue influence, fraud, misrepresentation, or mistake
Lawful Object23–30Purpose must not be illegal, immoral, or against public policy
Certainty29Terms must be clear and unambiguous

Types of Contracts (India)

  • Void agreement (Section 2(g)): Not enforceable by law from the start (e.g., agreement with a minor, agreement in restraint of trade under Section 27)
  • Voidable contract (Section 2(i)): Valid until the aggrieved party chooses to rescind (e.g., contracts obtained through fraud or coercion)
  • Express contract: Terms explicitly stated in words
  • Implied contract: Terms inferred from conduct

Landmark Indian Cases

Mohori Bibee v. Dharmodas Ghose (1903, Privy Council): A minor mortgaged his property to obtain a loan. The court held that a contract with a minor is void ab initio under Indian law — not merely voidable. The lender could not recover the money because no valid contract ever existed. This remains the leading authority on minors' contracts in India.

Carlill v. Carbolic Smoke Ball Co. (1892, English — widely followed in India): Established that an advertisement can be a valid offer to the world at large, and using the product was sufficient acceptance — the foundation of unilateral contract theory.

United States Contract Law

US contract law draws from two sources depending on the type of transaction:

  • Common law — judge-made rules governing services, real estate, employment, and most non-goods transactions
  • Uniform Commercial Code (UCC) Article 2 — adopted in all US states, governs the sale of goods (tangible, movable items)

Common Law vs. UCC Article 2

FeatureCommon LawUCC Article 2
Applies toServices, real estate, employmentSale of goods
AcceptanceMust be mirror image of offerBattle of the Forms (§ 2-207): different terms may still form a contract
ModificationRequires new considerationNo additional consideration needed for good-faith modification
Statute of FraudsWriting required for land, 1-year+ contractsContracts for goods ≥ $500 must be in writing (§ 2-201)

Essential Elements (US)

  1. Offer: A specific, definite proposal capable of acceptance. Advertisements are generally invitations to deal, not offers.
  2. Acceptance: Must be a mirror image under common law; UCC is more flexible.
  3. Consideration: Something of legal value bargained for by each party — can be a promise, act, or forbearance.
  4. Capacity: Contracts with minors are voidable (not void as in India) at the minor's option.
  5. Legality: Subject matter must be legal; overly broad non-competes, gambling contracts may be void.

The Statute of Frauds (MY LEGS)

Certain contracts must be evidenced in writing:

  • M — Marriage
  • Y — One-Year rule (contracts that cannot be performed within one year)
  • L — Land
  • E — Executor's personal promises
  • G — Goods ≥ $500 (UCC)
  • S — Suretyship (guaranteeing another's debt)

Breach and Remedies (US)

  • Expectation damages: Put the non-breaching party where they would have been had the contract been performed
  • Consequential damages: For foreseeable losses flowing from the breach (Hadley v. Baxendale, 1854)
  • Specific performance: Ordered when money damages are inadequate — typically for unique goods or real property
  • Liquidated damages: Pre-specified damages clause enforceable if it was a reasonable estimate of harm (not a penalty)

Key US Cases

Common Mistakes

Misconception: Every agreement is a contract. Why it's wrong: An agreement becomes a contract only when it satisfies all essential elements — offer, acceptance, consideration, free consent, capacity, and lawful object. A promise to meet a friend for coffee is an agreement but lacks intention to create legal relations and consideration. Correct understanding: Use the test: "Would a court enforce this?" If any essential element is missing, there is an agreement but no contract.


Misconception: In both India and the US, a minor's contract is voidable. Why it's wrong: Under Indian law (Mohori Bibee v. Dharmodas Ghose, 1903), a contract with a minor is void ab initio — it never existed. The minor cannot ratify it on attaining majority. In the US, a minor's contract is voidable only at the minor's option; the other party is bound. Correct understanding: India = void; US = voidable at minor's election. This is one of the most commonly tested distinctions in comparative contract law.


Misconception: UCC Article 2 applies to all US contracts. Why it's wrong: UCC Article 2 only governs contracts for the sale of goods — tangible, movable items. Service contracts, employment, real estate, and insurance remain governed by common law even in the US. Correct understanding: Always ask first: is this a contract for goods or for something else? The answer determines which body of law applies.

Practice Questions

Recall

  1. What are the six essential elements of a valid contract under the Indian Contract Act, 1872? Guidance: List offer and acceptance, consideration, free consent, capacity, lawful object, and certainty. Cite the relevant sections for each.

  2. What does the MY LEGS mnemonic stand for in US contract law? Guidance: Marriage, one-Year rule, Land, Executor's personal promise, Goods ≥ $500, Suretyship. Explain why the Statute of Frauds exists — to prevent fraud and perjury in high-stakes contracts.

Understanding

  1. Why does Indian law treat a minor's contract as void rather than voidable? Guidance: Refer to Mohori Bibee v. Dharmodas Ghose (1903). The Privy Council reasoned that because a minor lacks capacity, there is no agreement at all. Contrast with US law where the policy choice is to protect minors by giving them (not the other party) the power to avoid.

  2. Explain the difference between expectation damages and consequential damages in US contract law. Guidance: Expectation damages restore the plaintiff to where they would have been had the contract been performed. Consequential damages cover foreseeable downstream losses. Use Hadley v. Baxendale: the mill owner could not recover lost profits because the carrier did not know the shaft was the only one.

Application

  1. A software company contracts to deliver a custom platform to a bank by March 1. The company delivers on April 15. The bank sues. Under US common law, what remedy is most likely and how would damages be calculated? Guidance: This is a service contract (common law). The bank would seek expectation damages — the cost of cover (hiring another vendor at a higher price) plus any provable consequential losses the company had reason to foresee. Discuss whether this is material or minor breach.

  2. Ramesh, a 16-year-old, borrows ₹50,000 from a moneylender for non-essential purposes. Is the contract enforceable in India? Would the answer differ in California? Guidance: India — void ab initio under Section 11 ICA and Mohori Bibee. Moneylender cannot recover the principal. California — voidable at Ramesh's option; he could disaffirm and recover any consideration already given.

Analysis

  1. A café posts "Coffee — $3" on its menu board. A customer walks in and says "I accept." Has a contract been formed under US common law? Under Indian law? Guidance: Under both systems, the menu is an invitation to treat, not an offer. The customer's statement is the offer; the café's acceptance (making the coffee) forms the contract. Analyse Lucy v. Zehmer and Carlill v. Carbolic Smoke Ball to show how both objective theory and invitation-to-treat doctrine operate.

  2. Compare how India and the US handle a contract where only one party has signed a written agreement. Does the Statute of Frauds require both signatures? Guidance: The Statute of Frauds generally requires a writing signed by the party to be charged (i.e., the defendant), not both parties. Analyse how this asymmetry can be strategically exploited and how the courts have responded.

FAQ

1. Is an oral contract enforceable in India? Yes, as a general rule. The Indian Contract Act does not require contracts to be in writing unless a specific statute demands it (e.g., a sale of immovable property under the Transfer of Property Act, 1882, must be in writing and registered). Oral contracts are fully enforceable, though proving their terms in court is harder. Always reduce important agreements to writing for evidentiary safety.

2. Can a contract be formed by conduct alone, without spoken or written words? Yes. An implied contract arises from the parties' conduct. If you walk into a restaurant, order food, and eat it, you have impliedly contracted to pay even if you never said "I agree." Indian law recognises this under Section 9 of the Indian Contract Act; US law similarly recognises implied-in-fact contracts. Note the distinction from quasi-contracts, which are imposed by courts regardless of any agreement.

3. What is the difference between a void agreement and an illegal contract? A void agreement is simply unenforceable — it produces no legal rights. An illegal contract goes further: the subject matter or object violates a statute or public policy, and courts may decline to assist either party. For example, an agreement in restraint of trade under Section 27 is void; a contract to commit a crime is illegal. All illegal contracts are void, but not all void agreements are illegal.

4. Does consideration need to be adequate (i.e., a fair price)? No, consideration does not need to be adequate, only sufficient — it must have some value in the eyes of the law. Courts will not inquire whether the bargain was fair. A peppercorn is sufficient consideration. However, gross inadequacy of consideration may be evidence of fraud or undue influence, which could make the contract voidable.

5. When will a US court order specific performance instead of damages? Specific performance is an equitable remedy granted when money damages are inadequate. This typically happens when the subject matter is unique — such as a particular parcel of land, a rare painting, or a one-of-a-kind business. Under UCC § 2-716, specific performance may also be ordered where the buyer cannot obtain substitute goods. Courts will not order specific performance of personal service contracts because that would amount to forced labour.

Quick Revision

  • Contract = agreement + enforceability; Section 2(h) ICA
  • Six essentials: offer, acceptance, consideration, free consent, capacity, lawful object
  • Void agreement = no legal effect from start; voidable = valid till avoided
  • India: minor's contract is void ab initio (Mohori Bibee, 1903)
  • US: minor's contract is voidable at the minor's option
  • UCC Article 2 applies to sale of goods; common law applies to services
  • MY LEGS = Marriage, one-Year, Land, Executor, Goods ≥ $500, Suretyship
  • Consideration need not be adequate, only sufficient
  • Expectation damages = "benefit of the bargain" rule
  • Consequential damages = foreseeable downstream losses (Hadley v. Baxendale)
  • Specific performance reserved for unique goods or land
  • Objective theory of assent — courts look at outward conduct, not subjective intent
