What Are the Essential Elements of a Valid Contract?
Under Section 10 of the Indian Contract Act, 1872, the essential elements of a valid contract are:
- Offer and Acceptance
- Intention to Create Legal Relations
- Lawful Consideration
- Competency of Parties
- Free Consent
- Lawful Object
- Certainty of Terms
- Possibility of Performance

If any essential element is missing, the agreement may become void, voidable, or unenforceable.
Meaning of Contract Under the Indian Contract Act, 1872
Section 2(h) of the Indian Contract Act states:
“An agreement enforceable by law is a contract.”
Thus:
Contract=Agreement+Enforceability by Law
An agreement becomes a contract only when legal requirements are fulfilled.
Difference Between Agreement and Contract
| Basis | Agreement | Contract |
|---|---|---|
| Meaning | Promise between parties | Legally enforceable agreement |
| Legal Enforceability | May or may not be enforceable | Always enforceable |
| Defined Under | Section 2(e) | Section 2(h) |
| Example | Social promise | Business transaction |
Example
Rahul promises to take Aman for dinner.
This is only a social agreement, not a contract.
But if Rahul agrees to sell his bike to Aman for ₹50,000 and Aman accepts, it becomes a contractual agreement.
Essential Elements of a Valid Contract under Indian Law
1. Offer and Acceptance
A valid contract begins with a lawful offer and lawful acceptance.
Offer
Defined under Section 2(a).
An offer means willingness to do or abstain from doing something with the intention of obtaining assent.
Acceptance
Defined under Section 2(b).
Acceptance occurs when the person to whom the proposal is made gives assent.
Essentials of Valid Acceptance
- Must be absolute and unqualified
- Must be communicated
- Must be according to prescribed mode
- Must be given by authorized person
Example
A offers to sell his laptop to B for ₹40,000.
B says “I accept.”
This creates a promise.
Important Case Law
Carlill v. Carbolic Smoke Ball Co. (1893)
Established validity of general offers to the public
2. Intention to Create Legal Relationship
The parties must intend legal consequences.
Social or domestic arrangements generally do not create contracts.
Example
A husband promises to gift jewellery to his wife.
Normally not enforceable.
But commercial agreements are presumed to create legal obligations.
Landmark Case
Balfour v. Balfour (1919)
Domestic agreements are generally not contracts.
3. Lawful Consideration
Consideration means “something in return.”
Section 2(d) defines consideration.
No Consideration⇒No Contract
Essentials of Consideration
- Must move at desire of promisor
- May move from promisee or third party
- Must be lawful
- Need not be adequate
- Must be real and possible
Example
A agrees to paint B’s house for ₹20,000.
Painting = consideration by A
Money = consideration by B
Exceptions to “No Consideration No Contract”
Under Section 25:
- Natural love and affection
- Past voluntary services
- Promise to pay time-barred debt
Important Case Law
Chinnaya v. Ramayya (1882)
Consideration may move from a third party.
4. Competency of Parties
Under Section 11, parties must be competent to contract.
A person is competent if:
- Major
- Of sound mind
- Not disqualified by law
Minor’s Agreement
A minor’s agreement is void ab initio.
Landmark Case
Mohori Bibee v. Dharmodas Ghose (1903)
The Privy Council held:
Agreement with minor is absolutely void.
Persons Disqualified by Law
- Foreign sovereigns (subject to conditions)
- Alien enemies
- Convicts
- Insolvents
5. Free Consent
Consent means parties agreeing upon the same thing in the same sense.
This is known as:
Consensus ad idem
Under Section 14, consent is free when not caused by:
- Coercion
- Undue influence
- Fraud
- Misrepresentation
- Mistake
Coercion
Defined under Section 15.
Committing or threatening any act forbidden by IPC/BNS to compel agreement.
Example
Threatening to assault someone unless they sign a contract.
Undue Influence
Section 16.
One party dominates the will of another.
Example
Doctor influencing patient unfairly.
Fraud
Section 17.
Intentional deception to induce contract.
Example
Selling fake gold as real gold.
Misrepresentation
Section 18.
False statement made innocently.
Mistake
Mistake may be:
- Mistake of fact
- Mistake of law
Bilateral mistake of fact makes agreement void.
Landmark Case
Raffles v. Wichelhaus (1864)
No consensus ad idem due to misunderstanding.
6. Lawful Object
Under Section 23, object must be lawful.
Object becomes unlawful if:
- Forbidden by law
- Fraudulent
- Immoral
- Opposed to public policy
- Defeats provisions of law
Example
Agreement for smuggling goods is void and illegal.
7. Certainty of Terms
Section 29 states agreements with uncertain meaning are void.
Example
“I will sell you one car at reasonable price.”
Uncertain because no definite terms.
8. Possibility of Performance
Section 56:
Impossible acts cannot become contracts.
Impossible Agreement⇒Void
Example
Agreement to bring a dead person back to life is void.
Landmark Case
Taylor v. Caldwell (1863)
Doctrine of frustration recognized.
9. Agreements Not Expressly Declared Void
Certain agreements are specifically declared void under ICA:
- Restraint of marriage
- Restraint of trade
- Restraint of legal proceedings
- Wagering agreements
Wagering Agreement
A wagering agreement depends on uncertain future events where neither party has control.
