Capacity, Free Consent and Lawful Object: CA Foundation Business Laws

Updated 4 October 2026

This topic tests whether an agreement is a valid contract. Parties must be competent (adult, sound mind, not disqualified), consent must be free (no coercion, undue influence, fraud, misrepresentation or mistake) and the object and consideration must be lawful. Solve questions by applying the rule to the facts and then stating the effect: valid, void or voidable.

Understand Capacity, Free Consent and Lawful Object

A contract needs more than offer and acceptance. The law asks three further questions. Can these parties contract? Did they agree freely? Is the deal itself lawful? If the answer to any is no, the agreement is either void or voidable.

Capacity. Under the Indian Contract Act 1872, a person is competent to contract if they are an adult (18 years, or 21 if a court-appointed guardian exists or the person's property is under the Court of Wards), of sound mind, and not disqualified by any law. A minor's agreement is void ab initio, meaning void from the start. A minor cannot ratify it on becoming an adult. A minor can be a beneficiary, for example a promisee or payee. A minor cannot be a partner, but may be admitted to the benefits of a partnership with the consent of all the partners. A minor is liable for necessaries supplied to them, but only from their own property, not personally.

Free consent. Consent is free when it is not caused by coercion, undue influence, fraud, misrepresentation or mistake. If consent is caused by the first four, the contract is voidable at the option of the party whose consent was not free. Mistake works differently. A mistake of both parties about a fact essential to the agreement makes it void. A mistake of one party only does not affect the contract. A mistake about Indian law does not excuse anyone.

Lawful object. The consideration and object must be lawful. They are unlawful if forbidden by law, defeat a law, are fraudulent, injure a person or property, or are immoral or against public policy. Sections 26 to 30 list agreements that are expressly void: in restraint of marriage, in restraint of trade, in restraint of legal proceedings, uncertain agreements, and wagering agreements. Learn these as a set, with their exceptions.

Key rules to remember

Competent party: Adult + sound mind + not disqualified by law; Majority is 18 years, or 21 if a court-appointed guardian exists or the Court of Wards manages the property.
Minor's agreement: Minor's agreement = void ab initio; No ratification after majority, no specific performance, and no estoppel against the minor on the plea of age. A minor is liable for necessaries only out of their own property.
Coercion (section 15): Committing or threatening to commit an act forbidden by the IPC, or unlawfully detaining or threatening to detain any property, with the intention of causing any person to enter into an agreement; Voidable. The act need not be forbidden where it is done, and the person making the threat need not be a party. Money paid under coercion must be returned (section 72).
Undue influence: Dominant position + use of it to obtain unfair advantage; Voidable. Burden of proving no undue influence lies on the dominant party. Typical relationships: parent-child, doctor-patient, guardian-ward.
Fraud: Act done with intent to deceive or induce a contract; Includes suggesting a falsehood as fact, active concealment, a promise made without intent to perform, and acts declared fraudulent. Mere silence is not fraud unless there is a duty to speak or silence is equivalent to speech. Voidable, with right to damages.
Misrepresentation: Innocent false statement, made with honest belief, that induces a contract; Voidable, but no damages. The right to rescind is lost if the party could discover the truth with ordinary diligence. This ordinary-diligence exception in section 19 applies where consent was caused by misrepresentation or by silence amounting to fraud under section 17(1), but not where there was an active false statement amounting to fraud.
Mistake: Bilateral mistake of fact essential to agreement = void; unilateral mistake = contract valid; Mistake of foreign law is treated as mistake of fact. Mistake of Indian law is no excuse.
Void agreements, sections 26 to 30: Restraint of marriage (26), trade (27), legal proceedings (28), uncertainty (29), wagers (30); Exceptions: sale of goodwill under reasonable restriction (27), arbitration of future disputes (28), and prizes for horse races of ₹500 or more (30).

How to solve Capacity, Free Consent and Lawful Object questions

Use this order for any problem question. It keeps your answer in the provision, facts, conclusion structure that earns marks.

1Read the facts and underline the parties' ages, relationships, statements made and any threat or pressure.
2Identify the issue in one line, for example: Is the agreement voidable for undue influence?
3State the rule in plain words with its exact conditions. Mention the section only if you are sure of it.
4Match each condition to a fact in the question, one by one.
5Check for exceptions: necessaries for a minor, silence with a duty to speak, ordinary diligence for misrepresentation or silence amounting to fraud (but not an active false statement), goodwill exception for trade restraint.
6State the effect: valid, void or voidable, and who can act (for example, only the aggrieved party can rescind).
7Add consequences if relevant: refund, restitution, damages, or no damages.
8Close with a one-line conclusion that answers the question asked.

Quickest way: Capacity, consent, object triage

When to use it: Use this when you have about 5 minutes for a 5-mark problem question and must decide the answer quickly.

Ask first: is any party a minor? If yes, the agreement is void, so write the minor rules and stop.
If both are adults, scan for pressure words: threat, dominant, false, concealed, mistaken.
Threat of an illegal act points to coercion. Trust or authority points to undue influence.
False statement: made with intent to deceive is fraud (a reckless statement without belief in its truth can also be treated as fraud under case law), honestly believed is misrepresentation.
Both parties wrong about a key fact: mistake, void.
Finally check the object for illegality, or a match with sections 26 to 30.
Write rule, application, conclusion in three short paragraphs.

Common mistakes in Capacity, Free Consent and Lawful Object

Saying a minor's agreement is voidable and the minor can ratify it after turning 18.
Students mix up minor's agreements with contracts voidable for lack of free consent.
Fix: Remember it as void ab initio. Ratification is not possible because there was never a contract to ratify.
Treating all five factors of free consent as making the contract voidable.
The factors are learned as one list.
Fix: Coercion, undue influence, fraud and misrepresentation make it voidable. Bilateral mistake makes it void. Unilateral mistake has no effect.
Calling every false statement fraud.
Students ignore the intent element.
Fix: Fraud requires intent to deceive. Under case law, a statement made recklessly without belief in its truth can also be treated as fraudulent. An honest false statement is misrepresentation, and only fraud gives a right to damages.
Saying silence is always fraud.
Students remember concealment but forget the rule on silence.
Fix: Silence alone is not fraud unless there is a duty to speak, as in contracts uberrimae fidei, or the silence is equal to speech.
Holding a minor personally liable for necessaries.
Students know the minor is liable and stop there.
Fix: Only the minor's property is liable, not the minor personally, and the goods must be suitable to the minor's condition in life.
Missing the exceptions to sections 27 and 28.
Students memorise only the general rule.
Fix: Note the exceptions with each rule: sale of goodwill for section 27, and arbitration clauses for future disputes for section 28.

Worked examples

Example 1

Ravi, aged 17, buys a motorbike from Sameer on credit and signs an agreement. Later he refuses to pay, saying he is a minor. Sameer sues. Advise Sameer.

Show the solution

Issue: Is the agreement with a minor enforceable?
Rule: A minor's agreement is void ab initio. A minor is liable only for necessaries, and then only from their own property.
Application: Ravi is 17, so he is a minor and the agreement is void. A motorbike is a luxury here, not a necessary.
Ravi cannot be made to pay under the agreement, and he cannot be sued personally. He also cannot be forced to ratify it later.

Answer: Sameer cannot enforce the agreement. It is void because Ravi is a minor and the motorbike is not a necessary, so Sameer's claim fails.

Example 2

Meera sells her house to Karan after he tells her the municipal corporation will demolish the area next year. He knows this is false. Meera later learns the truth. Can she cancel the contract? Does she get damages?

Show the solution

Issue: Is Meera's consent free?
Rule: Fraud is an act done with intent to deceive and induce the other party to contract. The contract is voidable at the option of the deceived party, who may also claim damages.
Application: Karan stated something he knew was false, meaning he acted with intent to deceive, and this induced Meera to sell.
Therefore the contract is voidable at Meera's option, and Meera may also claim damages for any loss.
If Meera could easily have discovered the truth, that would not defeat her claim, because Karan made an active false statement amounting to fraud. The ordinary-diligence exception applies only to misrepresentation or silence amounting to fraud.

Answer: Yes. Karan's statement was fraud, so the contract is voidable at Meera's option and she may rescind it and also claim damages.

Exam tips

Write the rule in plain words first, then apply it to the facts. Do not just state a conclusion.
Always say void or voidable in your conclusion. It is the examiner's main check.
Learn the fraud versus misrepresentation difference as a short list: intent, knowledge, damages and duty of diligence.
For section 26 to 30 questions, name the type of void agreement and its exception if there is one.
Nothing is deducted for wrong answers in this subjective paper, so attempt every question.

Practice questions from Indian Regulatory Framework

Capacity, Free Consent and Lawful Object: frequently asked questions

What is the difference between fraud and misrepresentation?

Fraud requires a false statement or act made with intent to deceive. Under case law, a statement made recklessly without belief in its truth can also be treated as fraudulent. In misrepresentation, the person honestly believes the statement. Both make the contract voidable, but only fraud allows a claim for damages.

How do I answer a minor's agreement question?

State that a minor's agreement is void ab initio. Then check whether the question involves necessaries, benefit to the minor, ratification or partnership. Apply the matching rule and conclude.

Is a contract caused by coercion void or voidable?

It is voidable at the option of the party whose consent was caused by coercion. That party can rescind it, and must return any benefit received.

Which agreements are void under sections 26 to 30?

They are agreements in restraint of marriage, restraint of trade, restraint of legal proceedings, uncertain agreements and wagering agreements. Each has limited exceptions, so learn those with the rule.
