Void Agreements and Agreements Void for Uncertainty
Updated 10 October 2026 · Fact-checked
A void agreement is not enforceable by law and cannot be enforced by either party. The Indian Contract Act expressly declares some agreements void, such as those in restraint of marriage, trade or legal proceedings, wagering agreements, and agreements whose meaning is uncertain (Section 29). In MCQs, match the facts to the right category.
Understand Void Agreements and Agreements Void for Uncertainty
An agreement is a promise or set of promises that people exchange. It becomes a contract only if it is enforceable by law. A void agreement is one that is not enforceable at all. Section 2(g) of the Act defines it as an agreement not enforceable by law. It is void from the start, so no one can sue on it.
The Act lists certain agreements as void even when the parties agree freely. These are: agreements in restraint of marriage (Section 26), agreements in restraint of trade (Section 27), agreements in restraint of legal proceedings (Section 28), uncertain agreements (Section 29), wagering agreements (Section 30), and agreements to do impossible acts (Section 56).
Restraint of marriage: Section 26 makes void every agreement in restraint of the marriage of any person other than a minor. A restraint on the marriage of a minor is not declared void by this section. Example: Ravi promises Meera ₹1,00,000 if she never marries. Meera is an adult, so this is void.
Restraint of trade: an agreement that stops a person from carrying on a lawful profession, trade or business is void to that extent. The main exception is the sale of goodwill. The seller can agree not to carry on a similar business within specified local limits, as long as the restriction is reasonable. The Indian Partnership Act also permits certain reasonable restraints, for example under Sections 11(2), 36(2) and 54. These cover a partner not carrying on a competing business during the partnership, an outgoing partner not carrying on a similar business within a specified period or local limits, and partners agreeing not to compete after dissolution of the firm.
Restraint of legal proceedings: Section 28 makes an agreement void if it absolutely restricts a party from enforcing their rights through ordinary courts, or limits the time within which a party may enforce their rights, or extinguishes a party's right or discharges a party from liability on the expiry of a specified period so as to restrict enforcement. There are two exceptions. A contract to refer to arbitration disputes that may arise between the parties is valid (Exception 1). A written agreement to refer existing questions to arbitration is also saved (Exception 2).
Uncertain agreements (Section 29): if the meaning of an agreement is not certain, or cannot be made certain, the agreement is void. Example: Ajay agrees to sell Sunil 'a quantity of rice' at 'a fair price', with nothing else to fix the amount or price. This is void. But if the meaning can be made certain, it is valid. Example: selling 'all the rice in my godown' is certain because the quantity can be determined. Another classic illustration: an agreement to sell 'a hundred tons of oil' is void because the kind of oil is not stated, unless the kind can be made certain from the context or the course of dealing between the parties.
Wagering agreements (Section 30): a wager is a promise to pay money or money's worth on an uncertain event, where one party wins and the other loses, and neither has any interest other than the stake. Wagering agreements are void. Exception: Section 30 saves subscriptions or contributions towards a plate, prize or sum of money of ₹500 or more to be awarded to the winner of a horse race. Also, genuine contracts of insurance and genuine share market transactions are not wagers.
Even a void agreement can have consequences. Section 65 requires anyone who has received a benefit under a void agreement, or under a contract that becomes void, to restore it.
Key formulas to remember
- Void agreement (Section 2(g))
- Void agreement = agreement not enforceable by law
- It is not enforceable from the start. No party can sue on it. Benefits received may still have to be restored under Section 65.
- Restraint of marriage (Section 26)
- Every agreement in restraint of the marriage of any person, other than a minor, is void
- A restraint on a minor's marriage is not declared void by this section. Courts have interpreted the rule as aimed at total restraint, with reasonable partial restraint treated differently. That is case-law interpretation, not the words of the section.
- Restraint of trade (Section 27)
- Agreement restraining lawful profession, trade or business = void; exception: sale of goodwill within specified local limits
- Restraint must be reasonable and tied to the area where the business was carried on.
- Restraint of legal proceedings (Section 28)
- Agreement that absolutely restricts enforcement of rights through courts, or limits the time within which rights may be enforced, or extinguishes a right or discharges liability on expiry of a specified period = void
- Exceptions: arbitration for disputes that may arise, and a written agreement to refer existing questions to arbitration.
- Uncertain agreements (Section 29)
- Meaning not certain, or not capable of being made certain = void
- If it can be made certain, it is valid.
- Wagering agreement (Section 30)
- Promise to pay money or money's worth on an uncertain event; each party stands to win or lose; no other interest = void
- Genuine insurance contracts are not wagers. Subscriptions or contributions towards a plate, prize or sum of money of ₹500 or more, to be awarded to the winner of a horse race, are saved.
How to solve Void Agreements and Agreements Void for Uncertainty questions
For any MCQ on void agreements, identify what the agreement does and then match it to a category.
- 1Read the facts and find the core promise: marriage, trade, courts, uncertain terms, a bet, or impossibility.
- 2Match it to the right Section: 26, 27, 28, 29, 30 or 56.
- 3Check whether a stated exception applies (minor, goodwill, arbitration, a prize of ₹500 or more for a horse race winner, certainty possible).
- 4For Section 29, ask if the missing details can be made certain from the context or later facts.
- 5For wagering, check if both parties have no real interest other than the stake and the outcome is uncertain.
- 6State the effect: void means unenforceable from the start.
- 7Choose the option that matches your conclusion and eliminate options that call it valid or voidable.
Quickest way: Keyword matching
When to use it: Use when you have about one minute per MCQ and the question is a direct scenario.
- Spot the keyword: 'never marry' = Section 26; 'shall not carry on business' = Section 27; 'cannot go to court' = Section 28; 'a quantity' or 'some goods' = Section 29; 'bet' or 'if the horse wins' = Section 30.
- Look for the exception word: 'goodwill', 'arbitration', 'minor', 'insurance'.
- If an exception applies, the agreement is valid. Otherwise it is void.
- Eliminate options that say voidable or valid.
Common mistakes in Void Agreements and Agreements Void for Uncertainty
Calling a void agreement voidable.
The two terms sound alike.
Fix: Void means no enforceability at all. Voidable is valid until the aggrieved party cancels it.
Treating every restraint of trade clause as valid if the parties agreed.
Students think freedom of contract has no limit.
Fix: Under Section 27 such agreements are void unless the sale of goodwill exception applies.
Declaring an agreement void under Section 29 even when the terms can be fixed.
Students stop at 'unclear' without checking if it can be made certain.
Fix: Ask if the context supplies the missing detail. If yes, it is valid.
Treating all insurance and share trading as wagers.
They involve uncertain events and money.
Fix: Insurance involves insurable interest, and genuine share deals are not wagers.
Applying the restraint-of-marriage rule to minors.
Students forget the minor exception.
Fix: Section 26 voids restraints on the marriage of persons other than minors.
Worked examples
Example 1
Arun sells his bakery and goodwill in Pune to Bhavna and promises not to start a bakery in Pune for five years. Is the agreement valid?
Show the solution
- The promise restrains Arun from carrying on a trade, so Section 27 is relevant.
- Section 27 has an exception for the sale of goodwill.
- Arun sold goodwill and the restraint is limited to Pune, the local area of the business.
- The restriction is reasonable, so the exception applies.
Answer: The agreement is valid, because it falls within the goodwill exception to Section 27.
Example 2
Karan agrees to sell Rohit 'some bags of cement' at 'a fair price'. Nothing else is said. What is the status of the agreement?
Show the solution
- The quantity is not stated: 'some bags' is indefinite.
- The price is 'a fair price' with no way to fix it.
- There is no context, course of dealing or later act that makes the meaning certain.
- Under Section 29, an agreement whose meaning is not certain or cannot be made certain is void.
Answer: The agreement is void for uncertainty under Section 29.
Exam tips
- Memorise the section numbers 26 to 30 in order: marriage, trade, legal proceedings, uncertainty, wagering.
- Always remember the exception for each: minor, goodwill, arbitration, certainty possible, and genuine insurance or a horse race prize of ₹500 or more.
- Watch for options mixing 'void' and 'voidable'. Only one is correct.
- Scenario MCQs often hide the category in one phrase, such as 'if it rains tomorrow' for a wager.

Void Agreements and Agreements Void for Uncertainty: frequently asked questions
What is the difference between a void agreement and a void contract?
A void agreement is not enforceable by law from the start (Section 2(g)). A void contract is one that was enforceable when made but becomes unenforceable from the time of a later event, for example impossibility (Section 2(j)). Rights already accrued before that event are not undone. Section 65 requires benefits received under either to be restored.
Is a wagering agreement illegal in India?
It is void under Section 30, so you cannot sue to recover the winnings. Some states have additional laws that make betting an offence.
Can a non-compete clause in an employment contract be enforced?
During employment, reasonable restrictions can be valid. After employment ends, a clause stopping you from working in your trade is generally void under Section 27.
When is an agreement void for uncertainty?
When its meaning is not certain and cannot be made certain. If the missing details can be worked out from the context, it is valid.
