What is Capacity to Contract?

The primary element of a valid partnership contract is the capability or eligibility of partners to form a business agreement. The capacity to contract here means the legal ability of an individual or an entity to enter into a partnership. According to business law, the partner must be competent and fulfill the specified criteria before signing a contract.


Section 11 of the Indian Contract Act, 1972 details the capacity in contract law. It defines the ability to form contracts based on three aspects. They are as follows.


  • Attaining specified age

  • Being of sound mind

  • Not be disqualified from entering into a contract on the basis of any law he is subjected to


Apart from contractual capacity, partnership contracts must also include the following.


  • Offer

  • Consideration

  • Intent

  • Legality

  • Acceptance


The meaning of contractual capacity can be understood in detail through norms and examples.


Refer to the official website of Vedantu for a detailed explanation.


Detailed Explanation of Capacity to Contract in a Business


Given below is a thorough explanation of the contractual norms to judge an individual’s capacity to enter into a contract.


1. Attaining the Age of 18

A minor does not hold the capacity of holding a contract in business. Any agreement made with a minor in business is void ab-initio, which means ‘from the beginning’. If any person aged below 18 years enters into a contract, he cannot ratify the agreement even when he turns 18. This means that an invalid agreement can never be ratified.


  • Minor being a Beneficiary in a Contract.

Even though a minor is prohibited from entering a contract, he can register himself as a beneficiary of an agreement. Section 30 of the Indian Partnership Act, 1932 mentions that a minor cannot participate as a partner in the business, but he can enjoy the benefits earned by the firm.


  • A Minor always enjoys the benefits of being a Minor

A minor gets to enjoy some extra benefits in business. This contractual benefit needs to be explained in terms of the capacity to contract with examples. For instance, if a minor pretends to be a major and enters into a contract, he can later plead the minority through some simple formalities. The rule of estoppel is not applicable to a minor.


  • Contract through the means of a Guardian

In some cases, a guardian can enter into a valid business contract on behalf of a minor individual. Here, the guardian has no right to bind a minor to buy any immovable property under the contract. However, with proper certification and approval, the minor’s property can be sold when required. 


  • Insolvency

According to business law, a minor cannot be declared insolvent at any point in time. Even if the minor owes some dues to the firm, he will not be held personally liable for it.


  • Mutual contract by a Minor and an Adult individual

When a joint contract is signed between a minor and major, it has to be done in the presence of the minor’s guardian. In such contracts, the liability of the contract is held by the adult.


2. An individual has to be of Sound Mind

Section 12 of the Indian Contract Act (1872) necessitates a person to be of sound mind, have a complete understanding of the contract terms and conditions, and hold the ability to judge its impact on his interests.


Here, the capacity of parties to the contract also applies to an individual who is usually of unsound mind and occasionally in sound mind. However, in this case, the contract has to be signed when he is in a state of complete soundness. A contract made by an individual of unsound mind shall be considered as null and void according to capacity law definition.


A person under the influence of any sort of intoxication is considered incapable of entering into a contract. Such individuals can make a contract only when they are sober and have a complete understanding of the contractual terms.


3. People Disqualified under Law

Other than minors and people of unsound mind, some individuals might be restricted from entering into any contract as well. Such individuals do not hold the capacity to contract under valid business laws. Disqualification under contractual laws could include reasons related to politics, legal status, etc. This could also happen when a person is a foreign sovereign, national enemy, convict, or insolvent.


  • Alien enemies: people who are having citizenship in countries who don't have cordial relationships with India or in a war situation are called Alien enemies. People signing the contract during a war situation is not encouraged and a contract during a peace situation is valid.

  • Convict Serving Sentence: People who are on Bail or serving their sentence are not allowed to sign a contract.

  • Legal professionals: People who work as judges, advocates, public prosecutors are not allowed to sign a contract related to their connections.


For example, Advocate has taken a case from a Y person, the legal proceedings are going on. So advocates cannot sign a contract with that person in buying that property.


  • Insolvent: The insolvent person is allowed to purchase the property but cannot sell his own property.

  • Company: The company is formed under the law. Different companies are bound by different laws. Here, the company is considered as an artificial person. The company cannot sign contracts outside its limits.

  4. Affective disorders: People having depressions or bipolar disorder will have frequent mood changes. So people with these problems are not allowed to be involved in any contract.
