15  Offer and Acceptance, Valid Contract: Concept, Elements, Importance and Forms

ImportantLearning Objectives

By the end of this chapter, the reader will be able to:

  1. State the statutory definition of a contract under Section 2(h) of the Indian Contract Act, 1872 and identify the conceptual lineage of Indian contract law in English common law and the codification project of the late nineteenth century.
  2. Identify and apply the essential elements of a valid contract under Section 10 of the Indian Contract Act, 1872, including offer and acceptance, lawful consideration, capacity, free consent, lawful object, and the absence of any provision making the contract void.
  3. Classify contracts on the bases of validity (valid, void, voidable, illegal, and unenforceable), formation (express, implied, and quasi), performance (executed, executory, unilateral, and bilateral), and form (oral, written, and electronic).
  4. Apply the rules on offer (Section 2(a)) and acceptance (Section 2(b)), including the distinction between offer and invitation to treat, the requirement that acceptance be absolute and unqualified, and the rules on communication and revocation under Sections 4 and 5.
  5. Evaluate the foundational case law on contract formation, including Carlill v. Carbolic Smoke Ball Co. (1893), Harvey v. Facey (1893), Lalman Shukla v. Gauri Datt (1913), Felthouse v. Bindley (1862), and Mohori Bibee v. Dharmodas Ghose (1903).

15.1 Introduction

The law of contracts is the doctrinal and procedural framework that supports voluntary exchange in a market economy. A market depends, at the most basic level, on the ability of two persons to make commitments to each other and to enforce those commitments against each other. The institution that converts a commitment into a legally enforceable promise is the contract, and the body of law that defines, regulates, and enforces contracts is the law of contracts.

Indian contract law has its principal statutory anchor in the Indian Contract Act, 1872, which was drafted by the Third Indian Law Commission under the chairmanship of Sir John Romilly and enacted by the Imperial Legislative Council during the term of Viceroy Lord Mayo. The Act is one of the earliest comprehensive codifications of contract law anywhere in the world, predating the equivalent codifications in the Anglo-American common law tradition. It draws substantially on the English common law of contract as it stood in the 1860s, adapted in some respects to Indian conditions and incorporating elements of the Roman-civilian tradition through the influence of the Justinian-derived French Civil Code of 1804.

This chapter, which opens the second part of Module 2, sets out the foundational concepts of Indian contract law: the definition of a contract, the elements of a valid contract, the principal types of contract, and the rules on offer and acceptance. The chapters that follow take up the elements in more detail. Chapter 16 addresses the concept of offer in further depth. Chapter 17 addresses fraud, misrepresentation, and consideration. Chapter 18 addresses major issues that arise in contract performance and enforcement. Chapter 19 addresses the law of insurance, the principal commercial application of contract law to specialised risk-transfer arrangements.

15.2 The Concept and Definition of a Contract

A contract is, in its essence, a legally enforceable promise. It is the institution by which one person undertakes a commitment to another and by which that commitment becomes capable of judicial enforcement. The elements of a contract are accordingly the elements of a promise that has crossed the threshold of legal enforceability.

15.2.1 The Statutory Definition

NoteSection 2(h), Indian Contract Act, 1872

“An agreement enforceable by law is a contract.”

The definition is short and presupposes the prior definition of “agreement” in Section 2(e):

“Every promise and every set of promises, forming the consideration for each other, is an agreement.”

The two definitions, taken together, mean that a contract is a promise (or set of promises) supported by consideration, that has the further attribute of being enforceable by law. The next several sections of the Act elaborate the conditions under which an agreement is so enforceable.

15.2.2 The Lineage of Indian Contract Law

The Indian Contract Act, 1872 was drafted by a commission whose principal members were Sir John Romilly, Sir William Macleod, and Sir Edward Ryan. The drafting drew principally on the English common law of contract as it stood at the time, including the great judgments of Lord Mansfield, Lord Eldon, and Lord Cairns, and on the early treatises of Pothier, Story, Anson, and Pollock. The Act’s substantive content is therefore an Indian codification of the English common law, with selected modifications.

Three features of the Act warrant specific mention. First, the Act applies throughout India, providing a single unified framework rather than the complex state-by-state arrangements that had previously governed contract relations. Second, the Act codifies general contract law (in Chapters I to X) and specifies the rules for particular kinds of contract (originally in Chapters XI and following, since substantially separated into the Sale of Goods Act, 1930 and the Indian Partnership Act, 1932). Third, the Act codifies but does not exhaust the common law: where the Act is silent, the courts continue to apply common law principles, particularly in areas such as undue influence and equitable remedies.

TipThe Indian Contract Act Has Endured Remarkably Well

A practitioner observation worth emphasising is that the Indian Contract Act, 1872, despite being more than a century and a half old, has endured remarkably well. The Act has been amended only sparingly since its enactment, and its core provisions on offer, acceptance, consideration, capacity, free consent, and frustration continue to be the active framework of Indian contract practice. The reasons include the doctrinal coherence of the original drafting, the willingness of Indian courts to adapt the application of the Act to changing commercial conditions, and the relatively conservative approach of the legislature to amendment.

15.3 The Elements of a Valid Contract

Section 10 of the Indian Contract Act, 1872 sets out the conditions under which an agreement is enforceable as a contract.

NoteSection 10, Indian Contract Act, 1872

“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 hereby expressly declared to be void.”

To this core list of elements, the Act and judicial interpretation have added the requirements of certainty, possibility of performance, and (in particular cases) compliance with prescribed legal formalities. The complete list of elements is therefore:

  1. offer and acceptance;
  2. lawful consideration;
  3. capacity of parties;
  4. free consent;
  5. lawful object;
  6. absence of any provision in the Act expressly declaring the agreement to be void;
  7. certainty of terms;
  8. possibility of performance; and
  9. legal formalities, where prescribed for the particular contract.

Each element is addressed in turn.

15.3.1 Offer and Acceptance

An agreement requires an offer by one party (the offeror or proposer) and an acceptance by another party (the offeree or acceptor). The detailed rules on offer and acceptance are examined in the second half of this chapter.

15.3.2 Lawful Consideration

Consideration, defined in Section 2(d), is “something in return” for the promise. It may consist of an act, an abstinence, or a promise. The consideration must be lawful: it must not be forbidden by law, must not defeat the provisions of any law, must not be fraudulent, must not involve injury to the person or property of another, and must not be regarded as immoral or opposed to public policy.

The principal exceptions to the consideration requirement are set out in Section 25, which preserves agreements in writing and registered between near relations on natural love and affection, agreements to compensate for past voluntary services, and agreements to pay a time-barred debt. Consideration is examined in detail in Chapter 17.

15.3.3 Capacity of Parties

Capacity, addressed in Sections 11 and 12, requires that the parties be of sound mind, of the age of majority, and not disqualified from contracting by any law to which they are subject. Minors, persons of unsound mind, and persons disqualified by particular legislation cannot enter into binding contracts. The leading authority is Mohori Bibee v. Dharmodas Ghose (1903), examined below.

15.3.5 Lawful Object

Section 23 requires that the object of the agreement be lawful, applying tests parallel to those applicable to consideration. An agreement with an unlawful object is void.

15.3.6 Not Expressly Void

The Act expressly declares certain categories of agreement to be void, including agreements without consideration (Section 25, with exceptions), agreements in restraint of marriage (Section 26), agreements in restraint of trade (Section 27), agreements in restraint of legal proceedings (Section 28), agreements with uncertain meaning (Section 29), and wagering agreements (Section 30). An agreement falling within any of these categories cannot be enforced as a contract regardless of any other compliance with Section 10.

15.3.7 Certainty of Terms

Section 29 provides that agreements the meaning of which is not certain or capable of being made certain are void. The requirement of certainty is operationalised through the rules on essential terms: an agreement that does not specify the parties, the subject matter, the price, and the quantity (in any context where these are relevant) is unlikely to be sufficiently certain to be enforceable.

15.3.8 Possibility of Performance

Section 56 provides that an agreement to do an act impossible in itself is void. Where the impossibility arises after the agreement is entered into, the doctrine of frustration applies and the agreement may be discharged.

15.4 Classification of Contracts

Contracts may be classified along several dimensions. Each classification illuminates a particular aspect of the contractual relationship.

15.4.1 Classification by Validity

NoteValidity-Based Classification

  1. Valid contract — a contract that satisfies all the elements of Section 10 and is therefore enforceable in court.

  2. Void agreement — an agreement that does not satisfy one or more of the elements (typically because the consideration or object is unlawful, or because the agreement falls within one of the expressly void categories) and is therefore not enforceable from the outset. Void agreements are dead at birth, in the technical phrase, “ab initio”.

  3. Voidable contract — a contract that is enforceable at the option of one of the parties but not at the option of the other. Voidable contracts arise where the consent of one party was obtained by coercion, undue influence, fraud, or misrepresentation. The aggrieved party may elect to avoid the contract or to affirm it.

  4. Illegal agreement — an agreement whose object or consideration is forbidden by law, prohibited by court, or which would defeat the provisions of any law. Illegal agreements are void, and any collateral arrangements made in furtherance of them may also be tainted.

  5. Unenforceable contract — a contract that satisfies the substantive elements but cannot be enforced because of some procedural deficiency, such as the absence of writing where writing is required, the absence of registration where registration is required, or the lapse of the limitation period for enforcement.

15.4.2 Classification by Formation

NoteFormation-Based Classification

  1. Express contract — a contract whose terms are stated in words, whether oral or written. Most commercial contracts are express contracts.

  2. Implied contract — a contract whose terms are inferred from the conduct of the parties, the circumstances of the transaction, or the usage of trade. Where a person enters a hotel, takes a meal, and walks out without paying, the courts will imply a contract to pay for the meal at the prevailing rate.

  3. Quasi-contract — strictly speaking, not a contract but a relationship analogous to a contract created by the law to prevent unjust enrichment. Quasi-contracts are addressed in Sections 68 to 72 of the Act and include the supply of necessaries to a person incapable of contracting (Section 68), the right of a person paying money on behalf of another to recover it from the other (Section 69), and the obligation of a person enjoying a non-gratuitous act to compensate for it (Section 70).

15.4.3 Classification by Performance

NotePerformance-Based Classification

  1. Executed contract — a contract in which the obligations of all parties have been fully performed.

  2. Executory contract — a contract in which the obligations of all parties remain to be performed.

  3. Unilateral contract — a contract in which the offeror has performed his part by the act of making the offer, with the offeree’s acceptance taking the form of performance. The classic example is Carlill v. Carbolic Smoke Ball Co. (1893), examined below.

  4. Bilateral contract — a contract in which both parties have undertaken obligations that remain to be performed at the time of formation. Most commercial contracts are bilateral.

15.4.4 Classification by Form

NoteForm-Based Classification

  1. Oral contract — a contract whose terms are stated in spoken words. Oral contracts are valid in Indian law for most commercial transactions, although they are evidentially difficult to prove and are accordingly used principally for low-value or routine transactions.

  2. Written contract — a contract whose terms are reduced to writing and (in some cases) signed by the parties. Written contracts are evidentially more secure and are required by law for certain categories of transaction.

  3. Electronic contract (e-contract) — a contract entered into through electronic means, whether by exchange of email, completion of an online form, or click-wrap acceptance of standard terms. The Information Technology Act, 2000 expressly recognises electronic contracts in Section 10A and confers legal recognition on electronic records and digital signatures. The Indian Contract Act applies to e-contracts in the same manner as to traditional written contracts.

TipE-Contracts Have Become the Default Form of Indian Commerce

A practitioner observation worth emphasising is that, since the entry into force of the Information Technology Act, 2000 and particularly since the explosive growth of digital commerce in India over the past decade, the e-contract has become the default form of contractual relationship in many sectors. Click-wrap and browse-wrap agreements at the point of online purchase, electronic master service agreements between businesses, and digitally-signed contracts of substantial value have all become routine. The substantive principles of the Indian Contract Act apply unchanged, but the operational practice has been transformed.

15.5 Offer (Section 2(a))

The offer, also called a proposal in the Indian Contract Act, is the first element of any agreement.

NoteSection 2(a), Indian Contract Act, 1872

“When one person signifies to another his willingness to do or to abstain from doing anything, with a view to obtaining the assent of that other to such act or abstinence, he is said to make a proposal.”

The definition has three elements: a signifying of willingness (the communication of the proposal), the content of willingness (an act or an abstinence), and the object of the proposal (obtaining the assent of the other person).

15.5.1 Essentials of a Valid Offer

NoteEssentials of a Valid Offer

  1. Capacity — the offer must be made by a person competent to contract under Sections 11 and 12.

  2. Communication — the offer must be communicated to the offeree. An offer that has not been communicated cannot be accepted.

  3. Definiteness — the terms of the offer must be sufficiently definite to permit acceptance. Vague or indefinite offers are not capable of acceptance.

  4. Intention to create legal relations — the offer must be made with the intention that, on acceptance, it will give rise to legally binding obligations. Social and domestic offers are typically not made with this intention.

  5. Distinguishable from invitation to treat — the offer must be distinguishable from a mere invitation to treat, which invites others to make offers but is not itself an offer capable of acceptance.

  6. Distinguishable from declaration of intention — the offer must be distinguishable from a mere statement of future intention or supply of information, which does not amount to an offer.

  7. Specific or general — the offer may be made to a specific person or to the world at large; in the latter case, acceptance occurs through compliance with the conditions of the offer.

15.5.2 Types of Offer

The principal types of offer recognised in Indian contract law include:

  1. Specific offer — an offer made to a specific person, capable of acceptance only by that person;

  2. General offer — an offer made to the world at large, capable of acceptance by any person who complies with its conditions;

  3. Cross offers — two parties make identical offers to each other in ignorance of each other’s offer; cross offers do not constitute a contract because there is no meeting of the minds;

  4. Counter offer — a response to an offer that varies its terms; a counter offer terminates the original offer and itself constitutes a new offer capable of acceptance or rejection;

  5. Standing offer — an offer that remains open for acceptance over a period or for a series of transactions, typically arising in tender and supply contracts;

  6. Continuing offer — an offer that continues to be capable of acceptance until accepted, rejected, lapsed, or revoked.

NoteCarlill v. Carbolic Smoke Ball Co. (1893): The General Offer

Carbolic Smoke Ball Company published an advertisement undertaking to pay £100 to any person who used its smoke ball as directed and contracted influenza. The advertisement also stated that £1,000 had been deposited with the company’s bankers to demonstrate the company’s sincerity. Mrs. Carlill used the smoke ball, contracted influenza, and claimed the £100. The company refused on a series of arguments, including that the advertisement was not an offer but a mere puff and that no contract could be formed with the world at large.

The Court of Appeal held that the advertisement was a general offer to the world at large, that performance of the conditions constituted acceptance, that the deposit demonstrated the intention to create legal relations, and that consideration was supplied by Mrs. Carlill’s use of the smoke ball. The case is the foundational authority on general offers and continues to be cited in contemporary cases involving advertisements, prizes, and rewards.

NoteHarvey v. Facey (1893): Offer Distinguished from Information

Harvey telegraphed Facey: “Will you sell us Bumper Hall Pen? Telegraph lowest cash price.” Facey replied: “Lowest price for Bumper Hall Pen £900.” Harvey then telegraphed: “We agree to buy Bumper Hall Pen for £900 asked by you.” Facey did not respond, and Harvey sued for specific performance.

The Privy Council held that there was no contract. Facey’s response was a mere statement of the lowest price, not an offer to sell. The case is the foundational authority on the distinction between an offer and the supply of information.

15.6 Acceptance (Section 2(b))

The acceptance is the second element of any agreement.

NoteSection 2(b), Indian Contract Act, 1872

“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.”

The definition presupposes the prior making of a proposal under Section 2(a), and it makes acceptance the constitutive moment of the promise.

15.6.1 Essentials of a Valid Acceptance

NoteEssentials of a Valid Acceptance

  1. Acceptance must be by the offeree — only the person to whom the offer is made can accept it. A general offer may be accepted by any person who satisfies the conditions of the offer.

  2. Acceptance must be absolute and unqualified — Section 7 requires the acceptance to be absolute and unqualified. A purported acceptance that varies the terms is a counter offer, not an acceptance.

  3. Acceptance must be communicated — the acceptance must be communicated to the offeror. Mere mental acceptance is not sufficient.

  4. Acceptance must be in the prescribed manner — where the offer prescribes a manner of acceptance, the acceptance must be in that manner. Where no manner is prescribed, the acceptance must be in some usual and reasonable manner.

  5. Acceptance must be made within the prescribed time — where the offer prescribes a time for acceptance, the acceptance must be made within that time. Where no time is prescribed, the acceptance must be made within a reasonable time.

  6. Acceptance must be made before the offer lapses or is revoked — an offer may lapse or be revoked, and any purported acceptance after the lapse or revocation is ineffective.

NoteLalman Shukla v. Gauri Datt (1913): Knowledge of the Offer

The defendant’s nephew had absconded. The defendant sent the plaintiff Lalman, his servant, to search for the boy and offered a reward to anyone who found him. Lalman did not know of the reward when he found the boy. He subsequently learned of the reward and claimed it.

The Allahabad High Court held that Lalman could not claim the reward because he had not known of the offer at the time of the act that supposedly constituted acceptance. Acceptance presupposes knowledge of the offer; without knowledge, the act is not an acceptance and no contract is formed.

NoteFelthouse v. Bindley (1862): Silence Is Not Acceptance

The plaintiff wrote to his nephew offering to buy a horse and adding “if I hear no more from you, I shall consider the horse mine”. The nephew did not respond but instructed the auctioneer Bindley to keep the horse out of an auction, intending to sell to his uncle. Bindley accidentally sold the horse, and the uncle sued.

The Court of Common Pleas held that no contract had been formed. The nephew’s silence was not acceptance. The offeror cannot impose acceptance on the offeree by stipulating that silence will be deemed acceptance. The case is the foundational authority on the proposition that mental acceptance and silence are insufficient to constitute acceptance.

NoteHyde v. Wrench (1840): Counter Offer Terminates the Original Offer

The defendant offered to sell a farm for £1,000. The plaintiff offered £950, which the defendant rejected. The plaintiff then accepted the original offer of £1,000.

The Court held that no contract had been formed. The plaintiff’s offer of £950 was a counter offer, which terminated the original offer of £1,000. After the counter offer was rejected, the original offer was no longer capable of acceptance. The case is the foundational authority on the rule that a counter offer terminates the original offer.

15.7 Communication and Revocation

Sections 4 and 5 of the Act govern the communication and revocation of offers and acceptances.

NoteSection 4: Communication When Complete

The communication of a proposal is complete when it comes to the knowledge of the person to whom it is made.

The communication of an acceptance is complete:

  1. as against the proposer, when it is put in a course of transmission to him so as to be out of the power of the acceptor (the postal rule);

  2. as against the acceptor, when it comes to the knowledge of the proposer.

The asymmetry creates a window during which the offeror is bound by the acceptance but the acceptor is not yet bound. The window has substantial practical importance in the postal rule applications.

The communication of a revocation is complete:

  1. as against the person who makes it, when it is put in a course of transmission so as to be out of his power;

  2. as against the person to whom it is made, when it comes to his knowledge.

NoteSection 5: Revocation of Proposals and Acceptances

A proposal may be revoked at any time before the communication of its acceptance is complete as against the proposer (that is, before the acceptance is put into a course of transmission to the proposer).

An acceptance may be revoked at any time before the communication of the acceptance is complete as against the acceptor (that is, before the acceptance comes to the knowledge of the proposer).

NoteAdams v. Lindsell (1818): The Postal Rule

The defendants made an offer by letter on 2 September. The plaintiffs received the letter on 5 September and immediately posted an acceptance, which was received on 9 September. Meanwhile, on 8 September the defendants had sold the goods to a third party.

The court held that a binding contract had been formed when the plaintiffs posted their acceptance on 5 September, before the defendants sold to the third party. The postal rule, adopted in Section 4 of the Indian Contract Act, holds that an acceptance by post is complete (against the offeror) at the moment of posting. The case is the foundational authority on the postal rule.

15.7.1 Modes of Revocation of Proposal

Section 6 sets out the modes by which a proposal may be revoked. A proposal is revoked:

  1. by the communication of notice of revocation by the proposer to the other party;

  2. by the lapse of the time prescribed in the proposal for its acceptance, or, if no time is so prescribed, by the lapse of a reasonable time, without communication of the acceptance;

  3. by the failure of the acceptor to fulfil a condition precedent to acceptance;

  4. by the death or insanity of the proposer, if the fact of his death or insanity comes to the knowledge of the acceptor before acceptance.

15.8 Importance of Contracts in Business

The institution of contract is foundational to the operation of any market economy. Several specific dimensions of the importance of contracts in commercial practice merit identification.

NoteFunctions of Contracts in Business

  1. Coordination of complex commercial relationships — large commercial transactions, including cross-border supply, mergers and acquisitions, and infrastructure projects, depend on detailed contractual frameworks that allocate rights, duties, and risks among the parties.

  2. Risk allocation — contracts allocate the risks of the transaction among the parties through provisions on warranties, indemnities, force majeure, limitation of liability, insurance, and dispute resolution.

  3. Specification of expectations — contracts specify the parties’ expectations of performance, providing a benchmark against which performance can be assessed and breach can be identified.

  4. Provision of remedies — contracts, supported by the law of contracts and the law of remedies, provide for the enforcement of expectations through damages, specific performance, injunction, and other relief.

  5. Reduction of transaction costs — by providing a standard legal framework, the law of contracts reduces the cost of negotiating, drafting, and enforcing each individual transaction.

  6. Support for capital formation — long-term contracts, particularly in lending, leasing, and licensing, support the deployment of capital in productive activity by providing assurance of future returns.

  7. Foundation of corporate governance — the corporation itself is, in important respects, a network of contracts, and the framework of contract law underpins the relationships among shareholders, directors, employees, suppliers, and customers.

TipThe Law of Contracts Is the Operating System of the Market Economy

A useful summary of the importance of contract law is that it is the operating system of the market economy. Just as the operating system of a computer enables specific applications to run by providing a stable underlying environment, the law of contracts enables specific commercial transactions by providing a stable underlying framework. The quality of the law of contracts is therefore consequential not only for the parties to specific contracts but for the operation of the economy as a whole.

15.9 Case Studies

15.9.1 Case Study 1: Mohori Bibee v. Dharmodas Ghose (1903): Capacity of Minors

Dharmodas Ghose, a minor, mortgaged his house to Brahmo Dutt to secure a loan. The mortgage instrument fully disclosed Ghose’s minority. After Ghose’s mother brought a suit on his behalf to set the mortgage aside, Brahmo Dutt sought to recover the principal of the loan, arguing that under the rule in Leslie v. Sheill (1914) the minor should be required to restore the property received.

The Privy Council held that the contract entered into by a minor in India is void ab initio, not merely voidable. The minor cannot ratify it on attaining majority, and the principle of restitution does not require the minor to repay what he has received under a void contract (subject to specific exceptions in the law). The case has been the foundational authority on the capacity of minors in Indian contract law for more than a century.

Discussion Questions

  1. What are the policy reasons for treating minors’ contracts as void ab initio rather than as voidable, and to what extent are those reasons still applicable in contemporary commercial practice?
  2. How does the Mohori Bibee rule interact with the doctrine of restitution and the obligation of a minor to compensate for non-gratuitous benefits received?
  3. To what extent should the rule be modified to accommodate the realities of contemporary digital commerce, in which minors routinely transact through electronic interfaces that do not verify age?

15.9.3 Case Study 3: Click-Wrap Agreements in Indian E-Commerce

A representative pattern in contemporary Indian commerce is the click-wrap agreement, in which a user purchasing a product or service online signifies acceptance of standard terms by clicking an “I accept” button or proceeding through a check-out workflow. The agreements typically run to many pages of dense legal text and are seldom read by users in any detail. The Information Technology Act, 2000 expressly recognises electronic contracts in Section 10A.

The legal status of click-wrap agreements has been considered in several Indian decisions, with the courts generally upholding their enforceability subject to standard requirements of conspicuous notice, opportunity to review, and absence of unconscionable terms. The Supreme Court’s discussions of standard form contracts in Central Inland Water Transport Corporation v. Brojo Nath Ganguly (1986) and the more recent decisions on consumer protection have shaped the contemporary application of these principles.

Discussion Questions

  1. To what extent does the click-wrap agreement satisfy the requirements of offer, acceptance, communication, and intention to create legal relations under the Indian Contract Act?
  2. How should the law balance the commercial efficiency of click-wrap agreements with the substantive protection of consumers against unfair terms?
  3. What features of a click-wrap interface, including the conspicuousness of the terms, the nature of the acceptance action, and the availability of language alternatives, are most relevant to the enforceability of the resulting agreement?

Lawful Consideration Consideration must be lawful, meaning not forbidden, not defeating any law, not fraudulent, not injurious, and not opposed to public policy or morality
Capacity of Parties Capacity requires that the parties be of sound mind, of the age of majority, and not disqualified by any law to which they are subject
Free Consent Consent must be free, meaning not caused by coercion, undue influence, fraud, misrepresentation, or mistake; the five vitiating factors are addressed in subsequent sections
