Topic 1
Agreement and kinds of contracts
Section 2(h): a contract is an agreement enforceable by law. Section 2(e): every promise and every set of promises forming consideration for each other is an agreement. Hence Contract = Agreement + Enforceability; "all contracts are agreements but all agreements are not contracts" (social, domestic and moral agreements are not).
Offer and acceptance
Intention to create legal relations
Balfour v. Balfour (1919) — domestic arrangement not a contract
Lawful consideration
Capacity of parties
Free consent
Lawful object
Not expressly declared void
Certainty and possibility of performance
Legal formalities where required
| Kind | Meaning | Example |
|---|---|---|
| Valid | Has all essentials; enforceable | Sale of a car for ₹5 lakh |
| Void agreement | Not enforceable from the start | Agreement with a minor |
| Void contract | Valid when made, becomes unenforceable later | Contract becomes illegal by a new law |
| Voidable | Enforceable at the option of one party | Consent obtained by coercion |
| Illegal | Forbidden by law; collateral agreements also void | Agreement to smuggle goods |
| Unenforceable | Valid but cannot be enforced due to a technical defect | Unstamped agreement |
| Contingent (Section 31) | Performance depends on a future uncertain event | Insurance, indemnity |
| Quasi-contract (Sections 68–72) | Obligation imposed by law without agreement | Money paid by mistake must be returned |
| Express / implied / executed / executory | By formation and performance | Bus ride (implied), sale on credit (executory) |
Quasi-contracts
- Supply of necessaries to a person incapable of contracting (Section 68).
- Payment by an interested person (Section 69).
- Obligation to pay for non-gratuitous act (Section 70).
- Finder of goods (Section 71).
- Money paid or goods delivered by mistake or coercion (Section 72).
Topic 2
Offer and acceptance
- Offer (Section 2(a)): signification of willingness to do or abstain from doing something with a view to obtaining the assent of the other.
- Types: express or implied; specific or general offer (Carlill v. Carbolic Smoke Ball Co., 1893); cross offers; counter offer; standing offer.
- Invitation to offer (price tags, catalogues, tenders, auctions) is not an offer — Pharmaceutical Society v. Boots (1953).
- Rules of acceptance: absolute and unconditional, communicated to the offeror, in the prescribed or usual manner, within reasonable time, by the offeree, before the offer lapses; silence is not acceptance (Felthouse v. Bindley, 1862).
- 1Offer complete
When it comes to the knowledge of the offeree
- 2Acceptance complete against the proposer
When put in course of transmission
- 3Acceptance complete against the acceptor
When it comes to the knowledge of the proposer
- 4Revocation of offer
Any time before acceptance is complete against the proposer
Exam tip
Lalman Shukla v. Gauri Dutt (1913): a person who finds a missing boy without knowing of the reward cannot claim it — acceptance requires knowledge of the offer.
Topic 3
Capacity to contract
Section 11: every person is competent who is of the age of majority (18), of sound mind (Section 12) and not disqualified by law.
- Minor: agreement is void ab initio (Mohori Bibee v. Dharmodas Ghose, 1903); no ratification on attaining majority; no estoppel; minor can be a beneficiary/promisee; liable for necessaries out of their property (Section 68); can be admitted to the benefits of partnership.
- Unsound mind: contracts during unsoundness void; lucid intervals allowed.
- Disqualified persons: alien enemies, foreign sovereigns, convicts, insolvents.
Topic 4
Free consent, consideration and legality of object
Consent (Section 13): agreeing upon the same thing in the same sense (consensus ad idem). Free consent (Section 14): not caused by:
Coercion (Section 15)
Threat to commit an act forbidden by IPC/BNS or unlawful detention — voidable
Undue influence (Section 16)
Domination of will by a person in a position of trust — voidable
Fraud (Section 17)
Deliberate false representation — voidable + damages
Misrepresentation (Section 18)
Innocent false statement — voidable
Mistake (Sections 20–22)
Bilateral mistake of fact — void; mistake of law — no relief
Consideration
Section 2(d): when at the desire of the promisor, the promisee or any other person has done or abstained, or does or abstains, or promises to do or abstain from something, such act, abstinence or promise is consideration.
- Must move at the desire of the promisor; may move from the promisee or any other person (Chinnaya v. Ramayya, 1882); may be past, present or future; need not be adequate; must be real and lawful.
- "No consideration, no contract" (Section 25) — exceptions: natural love and affection (written and registered), compensation for past voluntary service, promise to pay a time-barred debt (written and signed), agency (Section 185), gifts actually made.
Legality of object (Sections 23–30)
The object or consideration is unlawful if it is forbidden by law, defeats any law, is fraudulent, injures person or property, or is immoral or opposed to public policy.
- Expressly void agreements: in restraint of marriage (Section 26), restraint of trade (Section 27 — except sale of goodwill), restraint of legal proceedings (Section 28), uncertain agreements (Section 29), wagering agreements (Section 30), agreements to do impossible acts (Section 56).

Actual or attempted (tender)

Novation, rescission, alteration, remission, waiver

Supervening impossibility — frustration (Taylor v. Caldwell, 1863)
