Introduction – Capacity to Contract

Capacity to contract refers to the legal ability of a person to enter into a contract that is enforceable by law. It is a fundamental requirement for the validity of a contract under Indian Contract Law, 1872. Without the requisite capacity, any agreement entered into may be void or voidable.

The law recognizes that certain individuals may lack the mental, legal, or social ability to understand the obligations and consequences of a contract. This ensures fairness and protects vulnerable parties from exploitation.


Definition – Capacity to Contract

Section 11 of the Indian Contract Act, 1872, lays down the rules regarding capacity to contract:

“Every person is competent to contract who is of the age of majority, is of sound mind, and is **not disqualified from contracting by any law to which he is subject.””

Thus, three main conditions determine capacity: age, soundness of mind, and legal disqualification.


1. Age of Majority

A person must have reached the age of majority to enter into a contract.

  • Definition: Under the Indian Majority Act, 1875, a person attains majority at 18 years.
  • Minor’s Contracts:
    • Void ab initio: A contract with a minor is void from the beginning and cannot be enforced by law.
    • Exceptions:
      1. Contracts beneficial to the minor – e.g., contracts for education, apprenticeship, or necessities.
      2. Contracts entered into by a guardian on behalf of a minor.

Case Example:
Mohori Bibee v. Dharmodas Ghose (1903) ILR 30 Cal 539 – The Privy Council held that contracts entered into by minors are absolutely void, establishing a fundamental precedent.

2. Soundness of Mind

A person must be mentally capable of understanding the nature and consequences of a contract.

  • Unsound Mind: A person who cannot comprehend the contract due to mental illness, temporary or permanent, is considered incapacitated.
  • Contracts by Lunatics:
    • Void if the person was incapable of understanding the contract at the time of formation.
    • Partially valid if the other party was unaware of the incapacity and the contract benefited the person.

Case Example:
R. vs. Coggs & Barnard (1703) – Demonstrated principles of consent and capacity for mental competence in early common law.

3. Disqualifications under Law

Certain persons are disqualified from contracting by law, including:

  1. Alien Enemies: During war, a citizen cannot contract with an enemy of the state.
  2. Persons Disqualified by Statute: Certain laws may prohibit contracts for specific individuals (e.g., insolvents under the Bankruptcy Act).
  3. Intoxicated Persons: Persons under the influence of alcohol or drugs at the time of contracting, if unable to understand the nature of the agreement.

Case Example:
Imperial Bank of India v. Santokh Singh (1956) – Contracts signed by intoxicated persons may be voidable if mental incapacity is proved.


4. Special Cases

a. Contracts by Married Women

  • Historically, married women had restrictions, but now under the Hindu Minority and Guardianship laws, they can contract independently.

b. Contracts by Corporations and Associations

  • Artificial persons like companies contract through authorized representatives.
  • The Companies Act, 2013, specifies that contracts outside the company’s memorandum of association may be ultra vires (beyond legal powers) and hence unenforceable.

5. Importance of Capacity in Contract Law

  1. Protection of Minors and Vulnerable Persons: Prevents exploitation and unfair obligations.
  2. Ensures Free Consent: Capacity is essential for understanding the terms and legal consequences.
  3. Maintains Legal Certainty: Courts can invalidate contracts entered by persons lacking capacity, reducing disputes.
  4. Social and Moral Responsibility: Encourages fairness and accountability in contractual relationships.

Key Case Laws on Capacity to Contract

  1. Mohori Bibee v. Dharmodas Ghose (1903 ILR 30 Cal 539) – Contracts by minors are void.
  2. R. vs. Coggs & Barnard (1703) – Highlighted importance of mental competence.
  3. Imperial Bank of India v. Santokh Singh (1956) – Contracts by intoxicated persons may be voidable.
  4. Ferry v. Burningham (1852) – Contracting capacity of lunatics; contract unenforceable if mental incapacity is proved.

Conclusion

Capacity to contract is a cornerstone of contract law, ensuring that only those legally competent can create enforceable obligations. It safeguards minors, mentally incapacitated persons, and other disqualified individuals from entering into binding agreements. The law strikes a balance between freedom to contract and protection of vulnerable parties, ensuring that contractual relationships remain fair, just, and enforceable.
