Quick Answer
Capacity to contract is the legal competence of a party to bind itself by agreement. Section 11 of the Indian Contract Act, 1872 says every person is competent to contract who is of the age of majority, of sound mind, and not disqualified from contracting by any law to which he is subject. Fail any one limb and the "agreement" cannot mature into a contract in the ordinary sense. The most important consequence flows from Mohori Bibee v. Dharmodas Ghose (1903): an agreement with a minor is void ab initio — not merely voidable — so it cannot be ratified, ordered specifically performed, or enforced against the minor even on grounds of estoppel or restitution, though Section 68 keeps the minor's estate liable for necessaries actually supplied. Persons of unsound mind (Section 12) and persons disqualified by other laws (alien enemies, insolvents, convicts) sit alongside minors as the three categories of legal incapacity that examiners test most often.
Core Concepts
Who Has Capacity: Section 11
Definition: Section 11 of the Indian Contract Act, 1872 provides: "Every person is competent to contract who is of the age of majority according to the law to which he is subject, and who is of sound mind, and is not disqualified from contracting by any law to which he is subject."
Explanation: Section 11 is a negative-cum-positive filter. It sets three cumulative conditions — majority, soundness of mind, and absence of legal disqualification — and a person must satisfy all three simultaneously to be treated as competent. The age of majority in India is governed by the Indian Majority Act, 1875: a person attains majority at 18, or at 21 if a guardian has been appointed by court for their person or property under the Guardians and Wards Act, 1890. Section 11 does not itself define "sound mind" or list "disqualifications" — those are picked up by Sections 12 and by other statutes respectively, which is why the section works as a signpost to the rest of this topic.
Example: A 17-year-and-11-month-old college student signs a loan agreement for a laptop. Regardless of how close he is to turning 18, he is a minor on the date of the agreement and fails the first limb of Section 11.
Real-World Example: Banks and NBFCs verify the date of birth on a PAN card or Aadhaar before disbursing a personal loan precisely because Section 11 makes any loan agreement with a minor a nullity — the lender would have no legal remedy to recover the principal as a contractual debt.
Why It Matters: Every other rule in this topic — void ab initio, necessaries, restitution — is simply working out what happens because someone fails the Section 11 test. Examiners build entire problem questions around identifying which limb of Section 11 is not satisfied.
Common Misunderstanding: Students often think Section 11 lists three independent grounds for a contract to be voidable. In fact, failing the "minor" limb produces a void agreement (per Mohori Bibee), while failing the "unsound mind" limb can, depending on the degree and timing of the unsoundness, still allow for some contracts made during lucid intervals — the consequences are not identical across the three limbs.
Minors and the Mohori Bibee Doctrine
Definition: A minor is a person who has not completed 18 years of age (or 21 years where a court-appointed guardian manages their person or estate). An agreement entered into by a minor is void ab initio — void from its very inception, as if it never existed in law.
Explanation: In Mohori Bibee v. Dharmodas Ghose (1903) 30 IA 114, Dharmodas Ghose, a minor, mortgaged his house to the moneylender Brahmo Dutt for Rs. 20,000, of which only about Rs. 8,000 was actually advanced. The moneylender's agent knew of the minority. When the moneylender sued to enforce the mortgage, the Privy Council held that since Section 11 makes majority a condition of competence, and since a minor cannot even give the "consent" contemplated by Section 10, there was no contract at all — the mortgage was void ab initio, not merely voidable. Because the agreement was void from the start, the doctrines that normally protect a party who benefited from a void contract — restitution under Section 65, or estoppel under Section 115 of the Evidence Act — could not be used to force the minor to repay or compensate the lender, since the minor never had contractual capacity to be estopped in the first place. This single case is the foundation of Indian minority law and displaced the earlier English position that treated some minors' contracts as merely voidable.
Example: A 16-year-old sells her scooter to a neighbour and takes payment, then later refuses to hand over the scooter. Because the sale agreement is void ab initio, the neighbour cannot sue for specific performance or damages for breach — there was never a contract to breach.
Real-World Example: Ed-tech and gaming platforms that require users to be 18+ to enter paid subscription agreements are not just following a marketing convention — they are avoiding entering into void agreements that would be judicially unenforceable against the minor if the minor later refused to pay.
Why It Matters: Void ab initio has teeth: no ratification on attaining majority (a fresh agreement, with fresh consideration, is needed), no specific performance, and ordinarily no restitution against the minor's own property under Section 65 (which applies only to agreements "discovered to be void," a phrase the courts have read as not covering agreements void from inception due to incapacity).
Common Misunderstanding: A common exam trap is assuming a minor's agreement is "voidable at the minor's option," on the mistaken analogy with a contract induced by misrepresentation. It is not voidable — it is void, full stop, and this distinction changes the entire remedy analysis (a voidable contract binds until rescinded; a void agreement never bound anyone).
Persons of Unsound Mind: Section 12
Definition: Section 12 states: "A person is said to be of sound mind for the purposes of making a contract if, at the time when he makes it, he is capable of understanding it and of forming a rational judgment as to its effect upon his interests." A person who is usually of unsound mind but occasionally of sound mind may contract during a lucid interval; a person who is usually of sound mind but occasionally of unsound mind may not contract while that unsoundness lasts.
Explanation: Unlike the minor's fixed status, Section 12 is transaction-specific and time-specific: the capacity is tested at the moment the contract is made, not by a general label such as "lunatic" or "person of unsound mind." Indian courts have consistently held (following Chiranjilal Chhaganlal Dalal v. Ranchhodal Haridas Luhar and earlier authority) that agreements by persons of unsound mind are, like a minor's agreement, void — because such a person cannot give the free and genuine consent Section 10 demands. Idiocy, lunacy, drunkenness to the point of incapacity, and hypnotic influence are all covered under this head, but the test is always functional: could the person understand this transaction and judge its effect on their interests at this moment, not whether a court has generally certified them insane.
Example: A person with an intermittent psychiatric condition signs a partnership deed during a period when doctors certify he was lucid and rational. The agreement is valid for that transaction even though the same person may have been incapable of contracting a week earlier.
Real-World Example: Hospitals dealing with end-of-life decisions or property transactions involving elderly patients with dementia routinely seek contemporaneous medical certification of mental capacity — exactly the Section 12 inquiry — because a transaction signed during a lucid interval is valid while one signed during an episode is not.
Why It Matters: Section 12 protects vulnerable people from exploitation while not permanently disabling them from ever transacting — a nuance that Section 11's fixed rule on minority does not need, since age moves in only one direction.
Common Misunderstanding: Students often equate "unsound mind" with a formal medical or judicial diagnosis of insanity. Section 12 requires no such certificate — it is a functional test of understanding at the time of contracting, so even an undiagnosed but momentarily incapacitated person (e.g., someone in severe delirium) can fail the test, and a diagnosed but currently lucid person can pass it.
Persons Disqualified by Law
Definition: Section 11's third limb excludes persons "disqualified from contracting by any law to which he is subject." This is a residual category picked up from other statutes and common law principles rather than defined exhaustively within the Contract Act itself. It principally covers alien enemies, foreign sovereigns and ambassadors (qualified immunity), insolvents, convicts, and — in a different sense — corporations acting outside their objects.
Explanation: An alien enemy (a subject of a country at war with India) cannot contract with an Indian citizen during the continuance of the war, except with the permission of the Central Government, because such contracts could aid the enemy state; contracts entered into before the war are usually suspended, not destroyed, and may revive after the war unless they have become time-barred or against public policy. An insolvent, once adjudicated under insolvency law, loses the capacity to deal with property vested in the official assignee/receiver until discharged. A convict undergoing imprisonment cannot enter into contracts during the currency of the sentence (though this incapacity is removed once released, or if given parole/leave in some jurisdictions). A company or statutory corporation, being an artificial legal person, can contract only for purposes within its objects clause under the doctrine of ultra vires — an act beyond its stated objects is void, not merely irregular, following principles from Ashbury Railway Carriage Co. v. Riche as adapted by Indian company law.
Example: During an armed conflict, an Indian trading company cannot lawfully enter into a fresh supply contract with a company headquartered in the enemy state without Central Government clearance, even if both parties are willing.
Real-World Example: When a company goes through insolvency proceedings under the Insolvency and Bankruptcy Code, 2016, the resolution professional — not the erstwhile directors — takes over the power to enter into contracts on behalf of the company, reflecting the same underlying principle that an insolvent's contractual capacity over its estate is legally curtailed.
Why It Matters: This category reminds students that capacity is not just about age and mental state — status under other branches of law (citizenship, insolvency, criminal sentence, corporate constitution) can independently strip a person or entity of the power to contract, and each has its own specific legal consequence rather than a single uniform rule.
Common Misunderstanding: Many students assume convicts and insolvents are "permanently" incapable of contracting, like the popular (mis)understanding of minority. In truth these disqualifications are temporary and status-linked — they end on release, discharge, or the cessation of war — unlike the fixed void-ab-initio consequence attaching to a minor's agreement made during minority.
Effect of a Minor's Agreement and the Doctrine of Restitution
Definition: Because a minor's agreement is void ab initio, no obligation arises from it; however, courts of equity have carved out a limited doctrine of restitution requiring a minor who has obtained property or goods by fraudulently misrepresenting his age to restore that specific property (not its money value) if it is traceable, and Section 33 of the Specific Relief Act, 1963 gives courts discretion to order such restitution when cancelling an instrument.
Explanation: The rule against enforcing a minor's agreement could, without limit, become a licence for fraud — a minor could lie about his age, obtain money or goods, and then plead minority to keep both the goods and the money. Indian courts, drawing on Leslie v. Sheill-type reasoning but adapted through the Specific Relief Act, have allowed restitution only of the actual property/goods still in the minor's possession or traceable in his hands — not a personal money decree for the "value received," since that would be indirect contractual enforcement. This is a narrow equitable safety valve, not a general rule that minors must always return benefits received.
Example: A minor fraudulently represents himself as a major, borrows Rs 50,000, and uses it to buy a motorbike still in his possession. A court may order the bike (traceable property) restored to the lender but will not pass a money decree for Rs 50,000 against the minor personally.
Real-World Example: Consumer platforms that discover a "buy now, pay later" account was opened using a falsified date of birth by a minor typically recover the purchased goods (if still available) rather than suing for the outstanding balance as a debt, mirroring the restitution principle rather than contractual enforcement.
Why It Matters: This shows examiners that "void ab initio" is not an absolute bar to any remedy whatsoever — equity supplies a narrow, property-specific fix for fraud, without reviving the underlying void agreement.
Common Misunderstanding: Students often conflate restitution of specific property with enforcement of the void agreement itself, and wrongly conclude a minor can be made to pay damages or interest. The doctrine is strictly limited to tracing and returning the actual benefit obtained by fraud, never to compensating the other party for loss of bargain.
Necessaries Supplied to a Minor: Section 68
Definition: Section 68 of the Indian Contract Act, 1872 provides that if a person incapable of entering into a contract (or anyone he is legally bound to support) is supplied by another person with necessaries suited to his condition in life, the person who has furnished such supplies is entitled to be reimbursed from the property of such incapable person.
Explanation: Section 68 is not a contract at all — it creates a quasi-contractual obligation so that the minor's estate (his property), not the minor personally, reimburses a reasonable amount for necessaries actually supplied and actually necessary at the time of delivery. English authority in Nash v. Inman [1908] 2 KB 1 illustrates the boundary: a tailor supplied fancy waistcoats to a Cambridge undergraduate minor who was already adequately supplied with clothes by his father; the court held the goods were not "necessaries" given his existing supply, so the tailor could not recover even under the equivalent English rule. "Necessaries" is a relative concept — assessed by the minor's actual station in life and existing supply, and typically includes food, clothing, lodging, education, and medical treatment, but excludes luxuries. Crucially, liability attaches to the minor's property, if any; if the minor owns no property, there is no personal liability at all.
Example: A 16-year-old orphan living independently is supplied groceries and school fees by a local trader over several months. The trader can recover a reasonable amount from any property the minor owns, but cannot make the minor personally liable if he owns nothing.
Real-World Example: Hostel wardens and school administrators who extend credit for a minor boarder's mess bills or uniforms rely on Section 68-type reimbursement from the minor's guardian/estate rather than treating the arrangement as an enforceable personal contract with the minor.
Why It Matters: Section 68 balances the protective policy of voiding minors' agreements against the practical need for traders and service providers to be willing to supply essentials to minors without personal risk of total loss.
Common Misunderstanding: Students frequently say a minor is "personally liable" for necessaries as though a contract exists. The liability is quasi-contractual and reaches only the minor's property/estate — never a personal decree against the minor, and never if the minor has no property at all.

Common Mistakes
Misconception 1: A minor's agreement is voidable at the minor's option, just like a contract induced by fraud or misrepresentation.
Why It's Wrong: Mohori Bibee v. Dharmodas Ghose squarely held that because Section 11 makes majority a precondition of the very capacity to contract, there is no contract to begin with — it is void ab initio, not a valid contract that one party can choose to avoid.
Correct Understanding: Treat a minor's agreement as a legal nullity from day one: it cannot be ratified on attaining majority, cannot be specifically enforced, and does not create a debt recoverable against the minor personally — only Section 68 (necessaries) and the narrow restitution doctrine offer any recovery, and both target the minor's property, not a personal obligation.
Misconception 2: A person diagnosed with a mental illness can never validly enter into any contract.
Why It's Wrong: Section 12 tests capacity at the moment of the specific transaction, not by reference to a permanent diagnosis or label. A person "usually of unsound mind" who contracts during a lucid interval makes a perfectly valid contract for that transaction.
Correct Understanding: Always ask "was this particular person capable of understanding this particular transaction and its effect on their interests at this particular time?" — capacity under Section 12 is transaction-specific and time-specific, not status-based.
Misconception 3: Necessaries supplied to a minor create an ordinary personal debt that the minor must repay like any other loan.
Why It's Wrong: Section 68 does not validate a contract with the minor; it creates a separate quasi-contractual right of reimbursement, and that right is enforceable only against the minor's property/estate, and only to the extent such property exists.
Correct Understanding: If the minor has no property, the supplier of necessaries has no remedy at all, however genuine and necessary the goods supplied were — the loss falls on the supplier, which is precisely why traders are cautious about extending credit to minors without security.

Practice Questions
Recall
-
State the three conditions laid down in Section 11 of the Indian Contract Act, 1872 for a person to be competent to contract. Answer guidance: Recall the exact three limbs — age of majority (per the Indian Majority Act, 1875), soundness of mind, and absence of disqualification by any law the person is subject to — and note that all three must be satisfied simultaneously.
-
What did the Privy Council decide in Mohori Bibee v. Dharmodas Ghose regarding the legal status of a minor's agreement? Answer guidance: The Council held the mortgage was void ab initio, not voidable, because a minor lacks the very capacity Section 11 requires, so restitution and estoppel could not be invoked against him.
Understanding
-
Explain why Section 12's test for "sound mind" is described as transaction-specific rather than status-based. Answer guidance: Discuss that capacity is assessed at the moment of contracting, allowing a generally unsound-minded person to contract validly during a lucid interval, and a generally sound-minded person to lack capacity during a temporary episode.
-
Why does Section 68 impose liability on a minor's property rather than on the minor personally? Answer guidance: Because the underlying agreement is void, no personal contractual obligation can arise; Section 68 instead creates a quasi-contractual, property-limited reimbursement right so that suppliers of essential goods are not left entirely without remedy, while the protective policy behind minority is preserved.
Application
-
A 17-year-old borrows money by falsely claiming to be 19, uses it to buy a laptop, and still possesses the laptop when the lender discovers the fraud. Can the lender recover the money or the laptop? Answer guidance: The lender cannot recover the money as a debt (agreement is void ab initio), but may seek restitution of the specific, traceable property — the laptop — under the equitable doctrine applied through the Specific Relief Act, since the minor obtained it through fraudulent misrepresentation of age.
-
A trader supplies school uniforms and books to a 15-year-old whose parents are alive and already provide him adequately. Can the trader recover payment under Section 68? Answer guidance: Apply the Nash v. Inman reasoning — if the minor is already adequately supplied with such items given his condition in life, the goods may not qualify as "necessaries," and the trader's Section 68 claim would likely fail on that ground, regardless of the minor owning property.
Analysis
-
Critically analyse whether the void-ab-initio rule for minors' agreements, as laid down in Mohori Bibee, adequately balances protection of minors against the risk of enabling fraud by minors who misrepresent their age. Answer guidance: Weigh the protective rationale (minors need protection from exploitation and improvident bargains) against the fraud risk, and explain how the narrow, property-specific restitution doctrine and Section 68 partially plug this gap without reintroducing personal contractual liability, while still leaving genuine gaps (e.g., no remedy if property is not traceable or minor is propertyless).
-
Compare the legal consequences of incapacity due to minority with incapacity due to a temporary insolvency disqualification, and explain why the law treats them differently. Answer guidance: Minority incapacity is inherent to the person and produces a permanently void agreement for that transaction with no possibility of ratification; insolvency disqualification is a status-based, temporary bar tied to the pendency of insolvency proceedings and vests contractual power over the estate in a resolution professional/official assignee, ending automatically on discharge — reflecting that the law's purpose (protecting the vulnerable vs. protecting creditors' collective interests) differs across the two categories.
FAQ
Q1: Can a minor be a partner in a partnership firm in India? A: No, a minor cannot become a full partner because that requires entering into a contract of partnership, which is void under the Mohori Bibee principle. However, under Section 30 of the Indian Partnership Act, 1932, a minor can be admitted only to the benefits of an existing partnership with the consent of all partners, without incurring personal liability for the firm's losses.
Q2: Does turning 18 automatically validate a contract signed while still a minor? A: No. Because the original agreement is void ab initio, there is nothing to "confirm" or ratify. The parties must enter into an entirely fresh agreement, supported by fresh consideration, after the person attains majority.
Q3: Is a contract signed by a drunk person automatically void? A: Only if the intoxication was severe enough, at the time of signing, to deprive the person of the ability to understand the contract and judge its effect on their interests — the Section 12 functional test applies to drunkenness just as it does to mental illness. Mild intoxication that leaves judgment intact does not affect capacity.
Q4: Can a company be held liable for a contract that falls outside its stated objects clause? A: Generally no — such a contract is ultra vires the company and void, since a company's contractual capacity is confined to its objects clause under its memorandum of association, though Indian company law has narrowed the practical impact of the ultra vires doctrine through provisions allowing objects clause amendments and protecting bona fide third parties in limited circumstances.
Q5: What happens to a contract if one party becomes insolvent after signing it but before performance? A: The contract itself was validly formed while the party had capacity; insolvency arising afterward is dealt with under insolvency law (e.g., the Insolvency and Bankruptcy Code, 2016), which may vest the power to perform or disclaim the contract in a resolution professional or liquidator, rather than retrospectively invalidating the original agreement.
Quick Revision
- Section 11: competence requires majority + sound mind + no legal disqualification, all three together.
- Age of majority: 18 years generally; 21 years if a court-appointed guardian manages the minor's person/property (Indian Majority Act, 1875).
- Mohori Bibee v. Dharmodas Ghose (1903): a minor's agreement is void ab initio, not voidable — no ratification, no estoppel, no restitution of money.
- Section 68: incapable person's estate/property (not the person) is liable to reimburse necessaries actually supplied and actually needed.
- Nash v. Inman: goods are not "necessaries" if the minor is already adequately supplied given his condition in life.
- Restitution doctrine: only specific, traceable property obtained by a minor's fraud on age can be recovered — never a money decree.
- Section 12: sound mind is tested at the time of contracting — a lucid interval validates a transaction; a temporary episode can invalidate one.
- Persons disqualified by law: alien enemies (during war, without government permission), insolvents (property vests in official assignee/resolution professional), convicts (during sentence), and companies acting ultra vires.
- Void agreement = no contract ever existed; voidable contract = valid until the aggrieved party rescinds it — do not conflate the two.
- A minor can be admitted to the benefits of a partnership under Section 30 of the Indian Partnership Act, 1932, but cannot be a full partner.
- Capacity (Section 11) is distinct from consent (Section 13-14): capacity asks "can this person contract at all," consent asks "did the parties agree on the same thing in the same sense freely."
