Historical Context Contract Law Before 1872

Before the Indian Contract Act, 1872 was enacted, there was no single, uniform law governing contracts in India. Contractual disputes were settled through a patchwork of personal laws, customs, and colonial directives.

Ancient & Mauryan Period
  • Governed by Vedas, Dharam Shastras, Smritis & Shrutis
  • Mauryan contracts were bilateral transactions
  • Based on free consent and mutual agreement
Mughal Period
  • 'Aqd' = Contract
  • 'Ijab' = Proposal / Offer
  • 'Qabul' = Acceptance
  • No special formality required
  • Free consent + agreement in same sense
Hindu Law
  • Based on customs, traditions & Smritikaras
  • Minors, intoxicated & old persons incompetent
  • After 16 years → competent (per Narada Smriti)
British Period
  • English law applied in Madras, Bombay & Calcutta
  • Charter of 1726 by King George
  • Outside Presidencies → justice, equity & good conscience
02
Foundation Introduction to the Indian Contract Act, 1872
Key Dates
  • Passed on: 25th April 1872
  • Came into force: 1st September 1872
  • Extends to the whole of India (incl. J&K)
Structure of the Act
  • Part 1 — General Principles (Sections 1–75): Offer, Acceptance, Consideration, Capacity, Consent
  • Part 2 — Special Contracts (Ss. 124–238): Indemnity, Guarantee, Bailment, Pledge, Agency
Preamble — Objective
"To define and amend certain parts of the law relating to contracts."
Exam Point Contract Law is the most important branch of mercantile law — it governs trade, commerce, industry and everyday business transactions. A contract is considered the foundation of the civilised world.
03
Section 2(e), 2(b) & 2(h) Agreement and Contract
Contract — Section 2(h)
"An agreement enforceable by law."
Agreement — Section 2(e)
"Every promise and every set of promises, forming the consideration for each other."
Promise — Section 2(b)
"When the person to whom the proposal is made signifies his assent thereto, the proposal is said to be accepted. A proposal when accepted becomes a promise."
Agreement = Offer / Proposal + Acceptance + Consideration
Contract = Agreement + Enforceability by Law
Golden Rule Every contract is an agreement, but every agreement is not a contract.

Difference Between Agreement and Contract

BasisAgreementContract
MeaningPromise + ConsiderationAgreement + Legal enforceability
ScopeWider — includes social & legal agreementsNarrower — only legally enforceable agreements
Legal ObligationMay not create legal obligationNecessarily creates legal obligation
NatureAll agreements are not contractsAll contracts are agreements
Example — Valid Contract
A agrees to sell his car to B for ₹2 lakhs. Both are bound — A must deliver, B must pay. Legal obligations arise → Valid Contract.
Example — Social Agreement (NOT a Contract)
A father promises ₹500 per month pocket money. Son cannot sue in court — no intention to create legal relations.
Status Obligations Obligations such as maintaining wife/children or court orders are outside Contract Law. These are called Status Obligations — not governed by the Contract Act.

Section 10 Essentials of a Valid Contract
Section 10
"All agreements are contracts if they are made by the free consent of the parties competent to contract, for a lawful consideration and with a lawful object and are not expressly declared to be void."
📌
Note Section 10 is not exhaustive. Additional elements not listed in Section 10 are also essential for a valid contract.

Essentials Listed in Section 10

  1. Agreement — Offer + Acceptance + Consideration (Section 2(e))
  2. Free Consent — Consensus ad idem (meeting of minds) — not caused by coercion, undue influence, fraud, misrepresentation, or mistake
  3. Competency of Parties — Major, sound mind, not disqualified by law (Section 11)
  4. Lawful Consideration — Quid pro quo (something in return)
  5. Legal Object — Not forbidden, fraudulent, immoral, or opposed to public policy (Section 23)
  6. Not Expressly Declared Void — Sections 24–30 and 56

Additional Essentials (Outside Section 10)

  1. Two Parties — A person cannot contract with himself; identity must be certain
  2. Intention to Create Legal Relationship — Social/domestic agreements generally excluded
  3. Fulfilment of Legal Formalities — Writing, witness, registration where required
  4. Certainty of Meaning — Terms must be clear, definite, certain
  5. Possibility of Performance — Impossible agreements are void
State of Gujarat vs. Ramanlal S & Co.
Two Parties Essential
Facts

On dissolution of partnership, assets were distributed among partners. The Sales Tax Officer treated this as a sale.

Held

It was not a sale. Partners were joint owners; the same persons cannot be both buyer and seller.

Legal Principle

A contract requires two distinct parties. One person cannot be both sides of a transaction.

Balfour v. Balfour
Intention to Create Legal Relationship
Facts

A husband promised to pay maintenance to his wife while abroad but failed to pay later.

Held

It was a domestic/social agreement. No intention to create legal relationship. Hence, not enforceable in court.

Legal Principle

Social and domestic agreements do not create legal relations and are therefore not enforceable as contracts.

Essential Elements Under Section 10 — Detailed

II. Free Consent — Consensus Ad Idem

Consent means the parties agree upon the same thing in the same sense — meeting of minds. Consent is free when NOT caused by:

III. Capacity of Parties — Section 11

Every person is competent to contract if they are:

IV. Consideration — Quid Pro Quo

Consideration means something in return. It may be a benefit to one party or a loss/responsibility to another.

V. Lawful Consideration and Object — Section 23

Consideration/object is unlawful if it is: forbidden by law, fraudulent, causes injury, immoral, or opposed to public policy.

VI. Not Expressly Declared Void

Illegal Agreements
  • Threat to murder
  • Defamation
  • Opposed to public policy
Void Agreements
  • Restraint of trade
  • Restraint of marriage
  • Restraint of legal proceedings
For a contract to be valid, all essential elements — agreement, free consent, lawful consideration, competency of parties, legal intention, certainty, and possibility of performance — must be present. Absence of any one renders the contract void, voidable, or unenforceable.
05
Classification Types of Contracts

I. On the Basis of Validity

Type 1
Valid Contract

Legally binding and enforceable. Contains all essential elements. Valid Contract = Agreement + All Essential Elements.

Type 2
Void Contract

Initially valid but later becomes unenforceable by law (Section 2(j)). Cannot be enforced in court. E.g., impossibility of performance after contract is formed.

Type 3
Voidable Contract

Enforceable at the option of one party only (Section 2(i)). Arises when consent is not free or one party prevents performance.

Type 4
Illegal Contract

Forbidden by law. Void ab initio. Collateral agreements also become void. E.g., agreements for purchase of drugs.

Type 5
Unenforceable Contract

Valid in substance but cannot be enforced due to a technical defect (absence of writing, non-registration, barred by limitation, lack of stamp duty).

Comparison: Void vs. Voidable Contract

BasisVoid ContractVoidable Contract
MeaningCeases to be enforceable by law (S. 2(j))Enforceable at option of aggrieved party (S. 2(i))
EnforceabilityCannot be enforced at allEnforceable only at option of aggrieved party
CauseChange in law or circumstancesConsent of a party was not free
PerformanceCannot be performedIf right not exercised within reasonable time, any party can sue

Key Rule All Illegal Agreements are Void, but All Void Agreements are not Illegal.
Formation of Contracts

II. On the Basis of Formation

1. Express Contract
  • Terms expressed clearly in words (spoken or written)
  • Section 9: promise made in words → express promise
2. Implied Contract
  • Arises from conduct, actions, or circumstances
  • Section 9: promise otherwise than in words → implied
  • Includes Tacit Contracts (silent, from conduct)
3. Quasi Contract
  • Not an actual contract — resembles one
  • Created by law to prevent unjust enrichment
  • No offer and acceptance required
4. E-Contract
  • Formed through electronic means
  • Also known as: cyber contracts, mouse-click contracts, EDI contracts

III. On the Basis of Performance

Executed Contract
  • Both parties have performed their obligations
  • Example: goods sold for cash payment — delivered & paid
Executory Contract
  • Obligations remain to be performed in the future
  • Unilateral: one party performed, other's obligation pending
  • Bilateral: obligations outstanding on both sides
06
Section 2(a) Proposal / Offer
Definition — Section 2(a)
"When one person signifies to another his willingness to do or abstain from doing anything with a view to obtaining the assent of that other person, he is said to make a proposal."
Terminology
  • Person making offer → Offeror / Promisor
  • Person to whom offer is made → Offeree
  • Person accepting → Promisee / Acceptor
Types of Offer
  • General Offer
  • Specific / Special Offer
  • Cross Offer
  • Counter Offer
  • Standing / Continuing / Open Offer

Types of Offers — Explained

General Offer
Made to the public at large. Anyone can accept by performing the conditions. Remains open until withdrawn or revoked (Section 8).
Carlill vs. Carbolic Smoke Ball Co.
1893 — Leading Case on General Offer
Facts

The company advertised that anyone using its smoke ball as directed and still contracting influenza would receive £100. £100 was deposited in a bank as a show of sincerity. Mrs. Carlill used the ball correctly, contracted influenza, and claimed the reward. The company refused, arguing there was no acceptance and no contract.

Held

The advertisement was a general offer. The deposit of £100 showed intention to create legal relations. Mrs. Carlill accepted the offer by performing the prescribed conditions. A valid contract existed; the company was liable to pay £100.

Legal Principle — General Offer

A general offer can be accepted by anyone by performing the stated conditions. Communication of acceptance is not necessary in case of a general offer.

Specific / Special Offer
Made to a specific person or definite group. Only that person can accept it.
Cross Offer
Two persons make identical offers in ignorance of each other's offer simultaneously. There is no acceptance and no contract — neither accepted the other's offer.
Counter Offer
Offeree accepts with modifications. Rejects the original offer and creates a new offer. Also called Conditional Acceptance.
Formula: Counter Offer = Rejection of Original Offer + New Offer
Standing / Continuing / Open Offer
An offer that remains open for acceptance over a period of time. Example: Tenders invited for supply of goods.

Legal Rules for a Valid Offer

  1. Must Create Legal Relationship — Social invitations do not create legal obligations
  2. Must be Certain — Clear, definite; vague offers cannot create a contract
  3. Must be Communicated — Acceptance without knowledge of offer is not valid
  4. Must Seek Assent — Must be made to obtain the other party's acceptance
  5. May be Conditional — Offeror may impose terms; offeree must accept all conditions
  6. Silence Cannot Amount to Acceptance — Offer cannot deem silence as acceptance
  7. May be General or Specific — To public at large or to a specific person
  8. May be Express or Implied — By words or by conduct
Lalman Shukla vs. Gauri Dutt
Offer Must be Communicated
Facts

Gauri Dutt sent his servant Lalman Shukla to search for his missing nephew. After Lalman had already left, Gauri announced a reward for anyone who found the nephew. Lalman found the boy without knowledge of the reward and later claimed it.

Held

Lalman Shukla was not entitled to the reward. Acceptance requires knowledge of the offer. Since he performed the act without knowing about the reward, there was no valid acceptance and hence no contract.

Legal Principle

Knowledge of offer is essential for acceptance. An act done in ignorance of the offer cannot constitute a valid acceptance or create a contract.

Offer Distinguished from Invitation to Offer

Invitation to Offer
Where a party, without expressing final willingness, proposes certain terms on which he is willing to negotiate — he does not make an offer but only invites the other party to make an offer on those terms.
Invitation to Offer ≠ Offer
BasisOfferInvitation to Offer
MeaningFinal expression of willingness to be bound (Section 2(a))Invitation for others to make an offer; no final willingness expressed
IntentionImmediately bound upon acceptanceWants to negotiate terms first
SequenceCannot precede invitation to offerAlways precedes an offer
Examples of Invitation to Offer
  • Prospectus of a company
  • Display of goods in a shop
  • Advertisement for auction
  • Quotation of prices / price lists
  • Menus in restaurants
Harvey vs. Facey
1893 — Statement of Price is Not an Offer
Facts

Harvey sent a telegram asking: (1) Will you sell Bumper Hall Pen? (2) What is the lowest price? Facey replied only to the second question: "Lowest price is £900." Harvey immediately sent a telegram saying he agreed to buy at £900. Facey refused to sell.

Held

The Privy Council held that while Harvey asked two questions, Facey only replied to the second — quoting the price — and reserved their answer regarding willingness to sell. Hence no offer was made, and no contract was formed.

Legal Principle

A mere statement of the lowest price is not an offer but only supply of information. An offer must show a clear intention to enter into a contract.

Harris vs. Nickerson
1873 — Advertisement for Auction is Invitation to Offer
Facts & Held

Defendant advertised that goods would be sold at auction. Plaintiff travelled to attend but goods were withdrawn before the sale. Court held that the advertisement was only an invitation to offer, not a binding offer. No contract arose and plaintiff could not claim damages. A contract is formed only when the auctioneer accepts a bid.

Legal Principle

An advertisement for auction is an invitation to offer, not an offer itself.

Mac Pherson vs. Appanna
1951 — Supreme Court of India
Facts & Held

Plaintiff offered ₹6,000 for a bungalow. Defendant replied "Won't accept less than ₹10,000." The plaintiff treated this as an offer and agreed to pay ₹10,000. The Supreme Court held that the statement was not an offer or counter-offer but merely a statement of minimum price. No contract was formed.

Legal Principle

A mere statement of the lowest price is only an invitation to offer and not a binding offer.

07
Section 2(b) Acceptance
Definition — Section 2(b)
"When the person to whom the proposal is made signifies his assent thereto, the proposal is said to be accepted. The proposal when accepted becomes a promise."
"Acceptance is to offer what a lighted match is to a train of gunpowder." — Sir William Anson

An offer alone has no legal effect until it is accepted. Before acceptance, the offeror can withdraw the offer. Once accepted, it becomes a promise and a binding contract is formed — it cannot then be revoked.

Offer + Acceptance = Contract

Legal Rules for Valid Acceptance

  1. Only by Person to Whom Offer is Made — Specific offer: only that person can accept. General offer: any person with knowledge of the offer.
  2. Must be Absolute and Unqualified — Acceptance must match the exact terms of the offer. Acceptance with variation = counter offer.
  3. Must be Communicated — Mental acceptance or silence is not acceptance. Must be expressed or implied.
  4. Must be in Prescribed Mode — If a mode is prescribed, acceptance must follow it (unless offeror waives it).
  5. Within Specified or Reasonable Time — Acceptance not given within reasonable time is not valid.
  6. Silence is Not Acceptance — Offeror cannot impose a condition that silence = acceptance.
  7. Acceptance by Conduct (Implied Acceptance) — Performance of conditions of offer amounts to acceptance.
Boulton vs. Jones
1857 — Acceptance Only by Person to Whom Offer is Made
Facts & Held

Boulton bought a business from Brocklehurst. Jones placed an order with Brocklehurst. Boulton supplied the goods though the order was not in his name. Jones refused to pay Boulton. Held: since the offer was not made to Boulton, there was no contract between Boulton and Jones.

Legal Principle

In case of a specific offer, it can be accepted only by the person to whom it is made.

Felthouse vs. Bindley
Silence Does Not Amount to Acceptance
Facts

Felthouse wrote to his nephew: "If I hear no more about the horse, I consider it mine at £30." The nephew intended to sell but gave no reply. The auctioneer Bindley accidentally sold the horse. Felthouse sued Bindley, claiming a valid contract existed with the nephew.

Held

There was no valid acceptance by the nephew. Mere silence cannot amount to acceptance. No binding contract existed between uncle and nephew.

Legal Principle

Silence does not amount to acceptance. Acceptance must be clearly communicated — mental intention is not sufficient.

Bhagwandas Goverdhandas Kedia vs. Girdharilal Parshottamdas & Co.
Communication of Acceptance — Telephone
Facts & Issue

Negotiations for purchase of cotton seed cake were conducted over telephone. A dispute arose regarding when acceptance was complete and at what place the contract was concluded (relevant for court jurisdiction).

Held

The Supreme Court held that telephone is an instantaneous mode of communication. Acceptance is complete only when it is actually received/heard by the offeror. The contract is formed at the place where acceptance is received.

Legal Principle

In instantaneous communication (telephone, telex, fax), acceptance is complete only when received by the offeror — not when spoken by the acceptor.

08
Section 4 Communication of Offer and Acceptance
Communication of Offer — Section 4
"The communication of offer is complete when it comes to the knowledge of the person to whom it is made."
📌
Note Mere receipt of a letter is not sufficient — the person must actually read the message. If a letter is received on 12th March but read on 15th March, the offer is communicated on 15th March.

Communication of Acceptance — Section 4

Against WhomWhen CompletePractical Meaning
Against the Proposer When acceptance is put in course of transmission, out of acceptor's power Moment the acceptor posts the letter → proposer becomes bound
Against the Acceptor When acceptance comes to the knowledge of the proposer Acceptor becomes bound only when proposer actually receives the acceptance
Postal Rule For postal acceptance, the proposer is bound from the moment the acceptor posts the letter — even if the letter is delayed, lost, or wrongly delivered — provided the letter is properly addressed, adequately stamped, and correctly posted.

Instantaneous Communication (Telephone / Telex / Fax / E-mail)

The contract is complete only when acceptance is actually received by the proposer. The contract is formed at the place where acceptance is received.

Entores Ltd. vs. Miles Far East Corporation
Instantaneous Communication — Telex
Facts

Entores (London) sent an offer by telex to Miles Far East (Holland). Acceptance was communicated through telex. A dispute arose regarding the place of contract formation (relevant for court jurisdiction).

Held

Telex is an instantaneous mode of communication. The contract is complete only when acceptance is received by the offeror. If the message is not received due to the acceptor's fault, there is no contract. However, if the offeror fails to receive due to his own fault, he may still be bound. The contract was concluded in London where acceptance was received.

Legal Principle

In instantaneous communication, acceptance is complete only upon receipt by the offeror, and the contract is formed at that place.

Indian Law vs. English Law — Postal Acceptance

AspectEnglish LawIndian Law
When acceptance postedContract immediately complete — acceptance CANNOT be revokedContract complete, but acceptance CAN be revoked before it reaches offeror
Rule NameAbsolute Postal RuleModified Postal Rule
FlexibilityNo flexibility for acceptorGreater flexibility — acceptor may revoke if revocation reaches before acceptance

Standard Form Contracts

A standard form contract is where one party prepares terms in advance and the other simply accepts. Also called boilerplate or take-it-or-leave-it contracts. Examples: transport contracts, railway tickets, insurance policies, mobile services, banking forms.

Key Rule A standard form contract may be enforced even if the other party is unaware of its contents, provided reasonable notice of the terms and conditions has been given. Conditions communicated after the contract is formed are NOT binding.
Mukul Datta vs. Indian Airlines
1962 — Printed Terms on Tickets
Facts & Held

A passenger booked a ticket subject to printed conditions. Dispute arose regarding enforceability of those terms. Court held that terms printed on a ticket are binding only if reasonable notice of them is given to the passenger. Hidden or unusual conditions are generally not enforceable.

Legal Principle

Terms and conditions are binding only when reasonable notice of them is given before or at the time of contract.

Lilly White vs. Mannuswamy
1966 — Exemption Clauses and Negligence
Facts

Customer gave clothes to Lilly White Dry Cleaners. The receipt contained a clause: "Articles accepted at owner's risk." Clothes were lost due to the dry cleaner's negligence. The dry cleaner argued the clause exempted them from liability.

Held

The vague clause "owner's risk" did not completely exclude liability for negligence. The dry cleaner was held liable to pay compensation.

Legal Principle

General exemption clauses cannot protect a party from liability arising out of their own negligence. Exclusion clauses must be clearly worded to cover the liability intended to be excluded.

Raipur Transport Co. vs. Ghanshyam
Special Conditions Must be Communicated Before Contract
Facts & Held

Transport company accepted goods without communicating any limiting conditions. After the contract was concluded, they issued a circular with conditions restricting liability. Court held that conditions communicated after the contract is completed are not binding. A party cannot unilaterally add terms after formation of the agreement.

Legal Principle

Special conditions in a standard form contract are binding only when reasonable notice of them is given before or at the time of contract.

09
Section 5 Revocation of Offer and Acceptance
Revocation — Meaning
Withdrawal or cancellation of a proposal (offer) or acceptance before a contract becomes final.

Communication of Revocation — Section 4

Against WhomWhen Complete
Against the person who makes itWhen it is put into course of transmission, out of his power
Against the person to whom it is madeWhen it comes to his knowledge

Revocation of Offer — Section 5

Section 5 — Rule
"A proposal may be revoked at any time before communication of acceptance is complete as against the proposer."

This means the offer can be revoked any time before the acceptor dispatches acceptance. Once acceptance is dispatched, the offer cannot be revoked.

Important Even if an offeror promises to keep an offer open for a certain time, he may still revoke it before acceptance — because a mere promise to keep an offer open is not binding without consideration.

Revocation of Acceptance — Section 5

Section 5 — Rule
"Acceptance may be revoked at any time before the communication of acceptance is complete as against the acceptor."

This means acceptance can be revoked before the acceptance letter reaches the proposer. If the revocation of acceptance arrives before (or simultaneously with) the acceptance letter, the revocation is valid under Indian law.

Modes of Revocation of Offer

  1. By Notice of Revocation — Offeror expressly withdraws the offer before acceptance
  2. By Lapse of Time — If not accepted within specified or reasonable time, offer lapses automatically
  3. By Non-Fulfilment of Condition Precedent — If a required condition is not fulfilled, offer automatically lapses
  4. By Death or Insanity — If offeror dies or becomes insane AND acceptor has knowledge of it
  5. By Counter Offer — If offeree makes a counter offer, the original offer is destroyed
  6. By Non-Acceptance in Prescribed Mode — If acceptance is not made in the prescribed or usual mode
  7. By Subsequent Illegality — If law changes and the proposed act becomes illegal, offer lapses automatically
Ramsgate Victoria Hotel Co. vs. Montefiore
Lapse of Offer Due to Delay
Facts

Montefiore applied in June for shares of the company. The company did not immediately accept. Five months later, in November, the company allotted shares and informed Montefiore. He refused to accept the shares. The company sued him claiming a valid contract.

Held

An offer cannot remain open forever. The delay of five months was unreasonable. The offer had lapsed before acceptance. No contract was formed.

Legal Principle — Lapse of Offer

An offer must be accepted within the prescribed time, or within a reasonable time if no time is prescribed. Unreasonable delay causes the offer to lapse automatically.

📌
Contracts Over Telephone / Telex Telephone contracts are treated like face-to-face contracts. Acceptance must be clearly heard and communication must be complete. If the line disconnects suddenly, the acceptor must reconfirm — otherwise no valid contract may arise.
