Every CLAT 2027 aspirant who has flipped through a Legal Reasoning passage in the last three years knows one uncomfortable truth: the Indian Contract Act, 1872 is the silent kingmaker of the section. Year after year, the Consortium quietly drops contract-flavoured passages, sometimes labelled as commercial disputes, sometimes wrapped inside consumer protection, sometimes hiding behind a quasi-contract restitution claim. If you cannot identify the doctrine in the first reading, you lose six to eight marks that the topper next to you will scoop up. This guide walks you through the twelve foundational doctrines you absolutely must internalise before December 2026, written in the same voice we use in our morning Legal Reasoning live classes.
Why Contracts Decides Your Legal Reasoning Score
The Legal Reasoning section in CLAT UG carries roughly 35 to 39 questions. Internal data from our 2024 and 2025 batches shows that 5 to 9 of those questions, across the Mock series and the official paper, are rooted in contract principles — offer, acceptance, consideration, free consent, capacity, void agreements, quasi-contracts, and frustration. If you crack contracts cold, you walk into the exam hall with a 6-mark cushion before the clock even starts. For more on how the section is weighted, see our Legal Reasoning strategy guide.
Doctrine 1 — Offer and Acceptance: The Mirror Image Rule
Section 2(a) of the Indian Contract Act defines a proposal as the act by which one person signifies willingness to do or abstain from doing something with a view to obtaining the assent of another. Section 2(b) tells us that the moment the offeree signifies assent, the proposal becomes a promise. The classroom rule we drill is the mirror image rule: acceptance must mirror the offer exactly. A counter-offer — even a tiny tweak in price, quantity, or delivery date — kills the original offer.
The CLAT favourite illustration is Carlill v Carbolic Smoke Ball Co (1893). The Smoke Ball Company advertised a £100 reward to anyone who used their ball thrice daily for two weeks and still caught influenza. The Court of Appeal held that the advertisement was a unilateral offer to the world, accepted by performance, and consideration moved from Mrs Carlill the moment she purchased and used the ball. Expect a CLAT passage to flip this around — for example, a coaching institute “guaranteeing” a rank or refund — and ask you whether a unilateral contract has been formed.
Doctrine 2 — Consideration: The Price of a Promise
Section 2(d) defines consideration as something done, abstained from, or promised at the desire of the promisor. Indian law departs from English law on two important points. First, consideration can move from the promisee or any other person — a stranger to consideration can still sue. Second, past consideration is good consideration in India. Currie v Misa remains the textbook quotation: “some right, interest, profit, or benefit accruing to one party, or some forbearance, detriment, loss, or responsibility given, suffered, or undertaken by the other.” Section 25 lists the exceptions where an agreement without consideration is still valid — natural love and affection in writing, compensation for past voluntary service, and time-barred debt promises.
Doctrine 3 — Intention to Create Legal Relations
Balfour v Balfour (1919) is the case that walks into your CLAT passage at least once every two years. Mr Balfour, posted in Ceylon, promised his wife £30 a month while she stayed in England for medical reasons. When the marriage broke down, she sued. The Court of Appeal held there was no intention to create legal relations — domestic agreements between spouses living amicably carry a rebuttable presumption against legal enforceability. Commercial agreements carry the opposite presumption. CLAT loves testing this with fact patterns involving family loans, sibling promises, and social club arrangements.
Doctrine 4 — Capacity to Contract (Section 11) and the Mohori Bibee Rule
Section 11 says only a person of the age of majority, of sound mind, and not disqualified by law is competent to contract. The age of majority under the Indian Majority Act, 1875, is 18 years. The 1903 Privy Council decision in Mohori Bibee v Dharmodas Ghose settled the position once and for all: a contract with a minor is void ab initio — void from the very beginning, not merely voidable. Even a minor who lies about his age can later raise minority as a defence; estoppel does not apply if the other party knew of the minority. The only carve-outs are necessaries supplied under Section 68 and contracts beneficial to the minor.
Doctrine 5 — Free Consent (Sections 13 and 14)
Section 13 says two parties consent when they agree upon the same thing in the same sense — consensus ad idem. Section 14 takes it further: consent must be free, meaning not caused by coercion, undue influence, fraud, misrepresentation, or mistake. If consent is caused by any of the first four, the contract is voidable at the option of the aggrieved party. If consent is caused by mistake of fact essential to the agreement, the contract is void. Train your eye to identify which vitiating factor a CLAT passage is describing — the answer choices will almost always include all five.
Doctrine 6 — Coercion vs Undue Influence
Coercion (Section 15) is the committing or threatening to commit any act forbidden by the Indian Penal Code, or the unlawful detaining of property, to make a person enter into an agreement. Undue influence (Section 16) is subtler — it arises where one party is in a position to dominate the will of the other and uses that position to obtain an unfair advantage. The classic CLAT trap: a son-in-law pressuring an elderly mother-in-law into transferring property is undue influence; a kidnapper at gunpoint demanding a signature is coercion. The remedy in both is the same — the contract is voidable.
Doctrine 7 — Fraud vs Misrepresentation
Section 17 defines fraud as a false statement, active concealment, or any act intended to deceive — made with knowledge of its falsity. Section 18 defines misrepresentation as an innocent false statement made in the honest belief that it is true. The pivot is intent. A car dealer who knows the odometer has been rolled back commits fraud; the same dealer who genuinely believes the seller’s word and repeats it to a buyer commits misrepresentation. In both cases the buyer can rescind, but only fraud unlocks damages.
Doctrine 8 — Lawful Object and Public Policy (Section 23)
Section 23 declares an agreement void if its consideration or object is forbidden by law, would defeat the provisions of any law, is fraudulent, involves injury to person or property, or is regarded by the court as immoral or opposed to public policy. The Latin maxim ex turpi causa non oritur actio — no action arises from a dishonourable cause — is the philosophical backbone here. CLAT passages frequently disguise this doctrine inside agreements restraining trade (Section 27), agreements in restraint of legal proceedings (Section 28), or wagering agreements (Section 30).
Doctrine 9 — Void Agreements vs Voidable Contracts
A void agreement is one that is not enforceable by law from the very beginning — for example, an agreement with a minor, an agreement without consideration, or an agreement with an unlawful object. A voidable contract is valid until the aggrieved party chooses to rescind it — for example, a contract obtained by coercion or fraud. The aggrieved party in a voidable contract has a window of reasonable time to exercise the option; delay can amount to ratification. This binary distinction is the single most commonly tested concept in CLAT contract questions.
Doctrine 10 — Quasi-Contracts (Sections 68 to 72)
Quasi-contracts are not contracts at all — they are obligations imposed by law to prevent unjust enrichment. The foundational maxim: no person should grow rich at another’s loss. Section 68 covers necessaries supplied to a minor or person of unsound mind — the supplier is entitled to reimbursement from the property of the incapable person. Section 70 covers non-gratuitous acts done for another. Section 71 makes a finder of goods responsible as a bailee. Section 72 mandates the return of money or goods delivered by mistake or under coercion. CLAT passages on income tax refunds wrongly retained, electricity dues paid twice, or goods delivered to the wrong address almost always resolve on Section 72.
Doctrine 11 — Performance and Discharge of Contracts
A contract can be discharged by performance, agreement (novation, rescission, alteration, remission), operation of law (insolvency, merger), breach (actual or anticipatory), or impossibility under Section 56. Performance must be exact, complete, and within the time stipulated. Section 37 obliges parties to perform their promises unless excused. Anticipatory breach — where a party declares before the performance date that he will not perform — gives the other party the immediate right to sue without waiting for the actual performance date. Always check whether the breach in your CLAT passage is anticipatory or actual; the remedies differ.
Doctrine 12 — Doctrine of Frustration (Section 56)
Section 56 codifies the doctrine of frustration: an agreement to do an act impossible in itself is void; a contract to do an act which, after the contract is made, becomes impossible or unlawful, becomes void. The landmark Indian authority is Satyabrata Ghose v Mugneeram Bangur & Co (1954). The Supreme Court clarified that “impossible” need not mean literally physically impossible — it covers events that destroy the very foundation of the agreement, rendering performance impracticable or substantially useless. Frustration dissolves the contract automatically. After Covid-19, CLAT examiners have leaned heavily on pandemic, lockdown, and force majeure fact patterns to test this doctrine.
How to Drill These Twelve Doctrines
Move from concept to case to passage in that order. First, read the bare section. Second, memorise the one landmark case per doctrine — Carlill, Balfour, Mohori Bibee, Satyabrata Ghose. Third, attempt at least twenty Legal Reasoning passages a week from our Daily Practice Papers archive. Fourth, sit a full CLAT mock test every Sunday and audit only your contract-tagged errors. Patterns will emerge inside three weeks.
5-Question Legal Reasoning MCQ — Practice Set
Passage: The Indian Contract Act, 1872 declares that an agreement enforceable by law is a contract. For a contract to be valid, there must be offer, acceptance, lawful consideration, free consent, capacity of parties, lawful object, and the agreement must not be expressly declared void. A contract with a minor is void from inception, whereas a contract vitiated by coercion or undue influence is voidable at the option of the aggrieved party. Quasi-contractual obligations under Sections 68 to 72 prevent unjust enrichment even in the absence of a valid contract.
Q1. Aarav, aged 17, sells his bicycle to Bharat for ₹5,000. Bharat refuses to pay. Aarav sues. Which is correct?
(a) Aarav can recover the price as the bicycle was delivered.
(b) The agreement is voidable at Bharat’s option.
(c) The agreement is void ab initio; no enforceable contract exists.
(d) Bharat must return the bicycle and pay the price.
Answer: (c). Under Mohori Bibee v Dharmodas Ghose, contracts with minors are void from the very beginning.
Q2. Chitra, under threat that her brother will be falsely implicated in a criminal case, signs a sale deed transferring her flat to Dev. What is the legal status of the contract?
(a) Void ab initio.
(b) Valid and binding.
(c) Voidable at Chitra’s option.
(d) Voidable at Dev’s option.
Answer: (c). Consent obtained by coercion under Section 15 makes the contract voidable at the option of the party whose consent was so caused.
Q3. A water supplier mistakenly delivers a tanker of water to Eshan’s house instead of Farhan’s. Eshan uses the water knowing it was not meant for him. Which provision applies?
(a) Section 56 — Frustration.
(b) Section 70 — Liability for non-gratuitous acts.
(c) Section 17 — Fraud.
(d) Section 23 — Unlawful object.
Answer: (b). Section 70 obliges Eshan to compensate the supplier for the benefit received because the delivery was not intended to be gratuitous.
Q4. Gaurav agrees to deliver imported wine to Heena’s bar. Before delivery, the government bans the import of that category of wine. The contract:
(a) Remains binding; Gaurav must pay damages.
(b) Is voidable at Heena’s option.
(c) Is discharged by frustration under Section 56.
(d) Must be specifically performed.
Answer: (c). Subsequent illegality discharges the contract automatically under the doctrine of frustration as clarified in Satyabrata Ghose.
Q5. Isha promises Jai ₹50,000 if he refrains from filing a defamation case against her. Jai forbears and demands payment. Is the agreement enforceable?
(a) No — forbearance is not consideration.
(b) Yes — forbearance to sue is good consideration under Section 2(d).
(c) No — the object is unlawful.
(d) Yes — but only if reduced to writing.
Answer: (b). Forbearance to sue qualifies as consideration; the agreement is enforceable provided the underlying claim was bona fide.
Frequently Asked Questions
Q1. How many marks does the Indian Contract Act typically carry in CLAT UG?
Across the last five Consortium papers and our internal Mock series, contract-rooted Legal Reasoning questions consistently account for 5 to 9 marks. That is roughly 15 to 22 per cent of the section — too large to ignore, too small to over-prepare.
Q2. Do I need to read the bare Act or are summaries enough?
For CLAT UG 2027, you do not need to memorise every section, but you must read the bare text of Sections 2, 10, 11, 13 to 18, 23, 25, 56, and 68 to 72. The Consortium has, in recent years, lifted passage language directly from these provisions.
Q3. Which is the single most important case for CLAT contracts?
If forced to pick one, Mohori Bibee v Dharmodas Ghose remains the most-tested case because it neatly intersects capacity, void agreements, and quasi-contractual restitution. Carlill v Carbolic Smoke Ball is a close second for offer and acceptance.
Q4. How should I revise contracts in the final month before CLAT 2027?
Three steps. First, revise the twelve doctrines above using flash-cards. Second, attempt twenty-five contract-tagged Legal Reasoning passages from our Daily Practice Papers in timed conditions. Third, audit your errors against the doctrine list and re-read only the doctrines where you scored below 70 per cent.
