Contract Law
Meaning, Nature and Scope of Contract
Learn what makes an agreement a contract, how Sections 2 and 10 work together, which promises the law enforces and where Indian contract law applies.
The short answer
A contract is a legally enforceable agreement created through consent, capacity, lawful consideration and object, and compliance with every rule that governs the transaction.
What is a contract under Indian law?
Section 2(h) gives the controlling definition: a contract is an agreement enforceable by law. The definition has two parts, agreement and legal enforceability.
An agreement records mutual promises, but enforceability asks a further question. Will a court recognise the promised obligation and grant a legal remedy if it is broken? A family understanding, a political assurance and a commercial sale may all contain promises, yet only the promise satisfying the legal requirements of contract becomes enforceable as such.
This distinction explains the familiar proposition that every contract is an agreement, but every agreement is not a contract. It also prevents a common error: offer and acceptance prove consensus, not the validity of the entire transaction.
The statutory chain from proposal to contract
Sections 2(a) to 2(h) form a sequence. Each term answers a different formation question.
Proposal
A person signifies willingness to do or abstain from doing something with a view to obtaining another person's assent. The statement must be capable of acceptance, not merely a request for information or an invitation to negotiate.
Acceptance and promise
When the person to whom the proposal is made signifies assent, the proposal is accepted. An accepted proposal becomes a promise under Section 2(b).
Promisor and promisee
The person making the proposal becomes the promisor, while the person accepting it becomes the promisee. These roles help identify who owes performance and who may demand it.
Consideration and agreement
The requested act, abstinence or promise may constitute consideration under Section 2(d). Promises forming consideration for each other become an agreement under Section 2(e).
Contract
The agreement becomes a contract only when it is enforceable by law. Section 10 supplies the principal enforceability test.
Section 10 enforceability checklist
A sound answer applies Section 10 element by element and then checks any special formality imposed by another law.
Free consent
The parties must consent to the same thing in the same sense, and that consent must not be caused by coercion, undue influence, fraud, misrepresentation or a legally operative mistake.
Competent parties
Each party must have attained majority, be of sound mind for the transaction and not be disqualified by a law applicable to that person.
Lawful consideration and object
Both what is exchanged and the purpose pursued must survive Section 23 and related statutory rules. A lawful form cannot rescue an unlawful bargain.
Not expressly void
The agreement must not fall within a category expressly declared void, such as certain restraints, uncertain agreements or wagers.
Required form
The Contract Act generally permits oral, written, implied and electronic agreements, but another law may require writing, attestation, registration or a particular electronic signature for the transaction concerned.
Nature of contractual obligation
Contractual liability usually rests on obligations voluntarily assumed, but legal control continues after apparent consent.
Contract law respects party autonomy by allowing people to arrange exchange, allocate risk and define remedies. That autonomy is not absolute. Rules on capacity, free consent, illegality, public policy, unfair consumer terms and mandatory statutory duties can restrict what parties may validly agree.
The law ordinarily uses an objective approach. It asks what the words and conduct would communicate in context, not what one party secretly intended. This makes correspondence, surrounding circumstances, trade usage and performance important when the court identifies the bargain.
Intention to create legal relations
The Indian Contract Act does not list intention as a separate phrase in Section 10, but courts use the setting and seriousness of a promise when deciding whether legal relations were contemplated.
Domestic and social arrangements are commonly presumed not to invite legal enforcement, though that conclusion can change where the arrangement is formal, relied upon, connected with separation or property, or otherwise shows legal seriousness. Commercial dealings normally point the other way, but labels and business settings are not conclusive if essential terms remain unsettled.
The safest exam method is to treat intention as part of the enforceability inquiry and support the conclusion with the parties' words, relationship, subject matter, certainty and conduct. It should not replace the statutory checks in Section 10.
Forms and classifications of contracts
Classification helps identify how the contract was made, whether it can be enforced and what remains to be performed.
By formation
A contract may be express in words, implied from conduct or formed electronically. Section 9 recognises express and implied promises, while the Information Technology Act supports electronic formation.
By enforceability
An arrangement may be valid, void, voidable, illegal or unenforceable because of a procedural defect. These labels have different consequences and should not be used interchangeably.
By performance
A contract may be executed, executory, unilateral or bilateral depending on whether performance has occurred and whether acceptance is by a return promise or a requested act.
By legal source
A true contract comes from consent. Obligations under Sections 68 to 72 resemble contractual duties but are imposed by law and are therefore restitutionary, not consensual contracts.
Scope and limits of the Indian Contract Act
The Act supplies general formation, performance, discharge and breach rules, together with rules for several named contractual relationships.
Sections 1 to 75 govern general principles and restitutionary obligations. Later chapters regulate indemnity, guarantee, bailment, pledge and agency. Sale of goods and partnership were moved into separate statutes, while consumer, employment, property, company, competition and digital laws may add mandatory rules.
The Act is therefore foundational but not exhaustive. A complete legal opinion identifies the transaction, applies the general contract rules, and then checks every special statute, required form, trade usage and binding precedent relevant to that transaction.
Leading cases and what they establish
Read each authority for the proposition it proves, the legal question it answers and the reasoning that supports the result.
Balfour v. Balfour
[1919] 2 KB 571
Held: A domestic arrangement made while the spouses were living amicably was not treated as a legally enforceable bargain in its context.
Why it matters: Use it to explain why factual agreement alone does not establish an intention to create legal relations.
Carlill v. Carbolic Smoke Ball Co.
[1893] 1 QB 256
Held: A clear public promise backed by an act showing seriousness operated as a unilateral offer accepted by performing its stated conditions.
Why it matters: Use it for objective intention, general offers and acceptance through performance.

Points that are often confused
- Writing that offer and acceptance automatically create a valid contract.

Questions to test understanding

Questions students ask
What is the simplest legal meaning of a contract?
A contract is an agreement enforceable by law. The parties must reach agreement, and the transaction must satisfy Section 10 and every applicable special legal requirement.
Is every agreement a contract?
No. An agreement may lack capacity, free consent, lawful consideration or object, certainty, legal intention or a required form. It may also be expressly declared void.
Does an Indian contract always require consideration?
Consideration is the general rule, but Section 25 recognises limited exceptions. Other statutory or restitutionary obligations may also arise without a consensual contract.
Can conduct create a contract?
Yes. Section 9 recognises implied promises. Conduct must objectively show assent to sufficiently certain terms and the remaining validity requirements must still be met.
Is the Indian Contract Act a complete code?
No. It provides central principles, but special statutes, required formalities, trade usages and judicial precedent can modify or supplement those principles.
