Competency of Parties to Contract under Section 11

Updated 10 October 2026 · Fact-checked

Under Section 11 of the Indian Contract Act, 1872, a person is competent to contract if they are of the age of majority, of sound mind, and not disqualified from contracting by any law to which they are subject. If any one condition fails, the person is not competent.

Understand Competency of Parties to Contract (Sections 10-12)

A contract is an agreement between parties. The law asks first: are these parties allowed to make a binding agreement? This is the question of competency. Without it, the agreement does not become a valid contract, however fair its terms may be.

Section 10 says all agreements are contracts if they are made by the free consent of parties competent to contract, for a lawful consideration and with a lawful object, and are not expressly declared void. Section 10 also lets the law require writing, registration or witnesses where a specific law demands it. So Section 10 lists the essentials, and Section 11 explains one of them: competency.

Section 11 sets three tests. First, the person must be a major under the law to which they are subject. Under the Indian Majority Act, 1875, this is 18 years, but 21 years where a guardian has been appointed by a court for the person or property, or where the person is under the Court of Wards. Second, the person must be of sound mind. Third, the person must not be disqualified by any law to which they are subject.

Section 12 explains sound mind. A person is of sound mind for contracting if, at the time of making the contract, they can understand it and form a rational judgment about its effect on their interests. So the test applies at the moment of contracting. A person who is usually of unsound mind can contract during a lucid interval. A person who is usually of sound mind cannot contract while delirious or so drunk that they cannot understand what they are doing.

Examples of persons disqualified by law include an alien enemy, a foreign sovereign or ambassador (who may need government consent to be sued), a convict undergoing sentence in jail, and an insolvent in respect of estate matters. Companies and other artificial persons have limited capacity based on their constitution and the law that governs them. In the exam, the focus is on the three tests and on spotting which one fails in a given case.

Key formulas to remember

Section 10: essentials of a valid contract: Free consent + competent parties + lawful consideration + lawful object + not expressly declared void; An agreement meeting these conditions is a contract. A specific law may also require writing, registration or witnesses.
Section 11: competency test: Competent = major + sound mind + not disqualified by any law; All three must be met. Failing any one makes the person not competent.
Age of majority: 18 years; 21 years if a court-appointed guardian exists or the person is under the Court of Wards; Under the Indian Majority Act, 1875. Below this age the person is a minor.
Section 12: sound mind: Sound mind = able to understand the contract and form a rational judgment about its effect on own interests, at the time of contracting; The test applies at the time the contract is made, not generally.

How to solve Competency of Parties to Contract (Sections 10-12) questions

Use this method for any question on competency of parties or the essentials of a valid contract.

1Read the facts and list every party to the agreement.
2Check age for each party. Is the person below 18, or below 21 where a guardian was appointed by a court or the Court of Wards applies?
3Check mind at the time of the contract. Was the person able to understand it and judge its effect? Ignore their usual state.
4Check for a legal disqualification, such as being an alien enemy, a convict in jail, or an insolvent for estate matters.
5If any test fails, conclude that the person is not competent under Section 11, so a Section 10 essential is missing.
6Match your conclusion to the options. Pick the one that names the failed test and the correct legal effect.

Quickest way: Three-gate check

When to use it: Use when the MCQ asks who is competent, or whether a given agreement satisfies Section 11.

Gate 1: age. Below 18 (or 21 with a guardian) means stop: not competent.
Gate 2: mind at the moment of contracting. Cannot understand means stop.
Gate 3: legal disqualification. Convict in jail, alien enemy, insolvent means stop.
If all three gates are passed, the person is competent. Then eliminate options that add extra conditions such as gender, wealth or education.

Common mistakes in Competency of Parties to Contract (Sections 10-12)

Saying the age of majority is always 21 years.
Older books and the guardian rule are remembered, but the general rule is forgotten.
Fix: Remember 18 as the general rule and 21 only when a court-appointed guardian exists or the Court of Wards applies.
Treating a person who is usually of unsound mind as always incompetent.
Students overlook that Section 12 tests the mind at the time of contracting.
Fix: Ask whether the person could understand and judge the contract at that moment. A lucid interval can make them competent.
Treating a usually sane person as competent even when drunk or delirious.
Students focus on the person's general condition.
Fix: Apply the same time-of-contract test. If they could not understand the contract then, they cannot contract.
Confusing Section 10 with Section 11.
Both deal with validity and are studied together.
Fix: Section 10 lists all the essentials of a valid contract. Section 11 explains only who is competent.
Assuming only age and mind matter for competency.
The third condition, disqualification by law, is skipped.
Fix: Always run the third gate. Convicts in jail, alien enemies and insolvents may be disqualified in some matters.
Thinking a person who is competent has an enforceable contract whatever the other terms.
Competency is mistaken for validity itself.
Fix: Competency is only one essential. Free consent, lawful consideration and lawful object must also be present.

Worked examples

Example 1

Ravi, aged 19, with no court-appointed guardian, of sound mind and not disqualified by any law, agrees to sell his bike to Meena for ₹40,000. Is Ravi competent to contract?

Show the solution

Age: Ravi is 19 and has no court-appointed guardian, so the age of majority is 18. He is a major.
Mind: he is of sound mind, so the Section 12 test is met.
Disqualification: no law disqualifies him.
All three Section 11 tests are satisfied.

Answer: Yes. Ravi is competent to contract under Section 11.

Example 2

Anil, aged 20, has a guardian appointed for his property by a court. He enters into an agreement to buy a shop. Is he competent to contract?

Show the solution

Because a court has appointed a guardian for his property, the age of majority is 21, not 18.
Anil is 20, so he is below 21 and is a minor for this purpose.
The first Section 11 test fails.
Whether his mind or legal status is fine does not matter, because one failed test is enough.

Answer: No. Anil is not competent to contract, because he is a minor under the extended age of 21.

Exam tips

Memorise the three tests in Section 11 in order: age, sound mind, not disqualified by law.
Watch the numbers in the question. 18 is the general age of majority, 21 applies with a court-appointed guardian or Court of Wards.
For sound-mind questions, look for the time of contracting, such as a lucid interval or intoxication at that moment.
If an option names a Section 10 essential that is not in the list, such as the contract being in writing, eliminate it unless the facts mention a law that demands writing.
Read the question word: 'competent' points to Section 11, while 'essentials of a valid contract' points to Section 10.
