Introduction
Contract law governs agreements between parties that create legally binding obligations. It forms the foundation of business transactions, employment relationships, and countless everyday interactions. Understanding contract law is essential for protecting your interests, avoiding disputes, and ensuring agreements are enforceable.
Core Concepts and Principles
Elements of a Valid Contract
| Element | Description |
|---|---|
| Offer | A clear proposal to enter into an agreement on specified terms |
| Acceptance | Unequivocal agreement to the exact terms of the offer |
| Consideration | Something of value exchanged between parties (money, goods, services, promises) |
| Intention | Both parties must intend to create legal relations |
| Capacity | Parties must have legal capacity to enter contracts (age, mental competence) |
| Legality | Contract purpose must be legal; illegal contracts are void |
| Certainty | Terms must be clear, complete, and not ambiguous |
Types of Contracts
- Express Contracts: Terms explicitly stated (written or verbal)
- Implied Contracts: Formed by conduct rather than words
- Bilateral Contracts: Both parties make promises (most common)
- Unilateral Contracts: Only one party makes a promise, contingent on the other party’s action
- Executory Contracts: Promises not yet performed
- Executed Contracts: All promises fully performed
- Void Contracts: Not legally enforceable
- Voidable Contracts: Can be affirmed or rejected by one party
Contract Formation Process
Pre-contractual Stage
- Parties negotiate terms
- Letters of intent/memoranda of understanding may be created
- Due diligence conducted
Offer Creation
- Must be definite, certain, and communicated
- Distinguished from “invitations to treat” (advertisements, price displays)
- Contains essential terms
Acceptance
- Must be unconditional and match offer exactly
- Must be communicated to offeror
- Takes effect when received (postal rule exception)
Exchange of Consideration
- Must be sufficient but need not be adequate
- Past consideration generally not valid
- Consideration must not be illusory
Formalization
- Written contracts for certain agreements (statute of frauds)
- Execution of documents
- Delivery and exchange
Contract Interpretation and Construction
Approaches to Interpretation
- Plain Meaning Rule: Terms interpreted by their plain, ordinary meaning
- Four Corners Rule: Document analyzed within its four corners without external evidence
- Parol Evidence Rule: Prior or contemporaneous agreements can’t contradict written contract
- Contra Proferentem: Ambiguities interpreted against the drafter
Construction Principles
- Entire Agreement: All terms must be considered together
- Implied Terms: Terms implied by law, custom, or necessity
- Course of Dealing: Prior conduct between parties can inform interpretation
- Trade Usage: Industry practices may supplement terms
Contract Modification and Discharge
Modification Requirements
- Mutual agreement
- New or additional consideration (in many jurisdictions)
- Formalities (if original contract requires)
Ways Contracts are Discharged
| Method | Description |
|---|---|
| Performance | Complete fulfillment of contractual obligations |
| Agreement | Mutual consent to terminate or novation (new contract) |
| Frustration | Supervening event makes performance impossible |
| Breach | Material failure to perform contractual obligations |
| Operation of Law | Bankruptcy, statute of limitations, merger |
Breach of Contract and Remedies
Types of Breach
- Material Breach: Substantial failure that defeats purpose of contract
- Minor Breach: Non-material failure that doesn’t prevent contract completion
- Anticipatory Breach: Clear indication party won’t perform before performance due
- Actual Breach: Failure to perform when due
Available Remedies
| Remedy | Purpose | Requirements |
|---|---|---|
| Damages | Monetary compensation | Measurable loss from breach |
| Specific Performance | Court order to perform | Unique subject matter, inadequate damages |
| Injunction | Court order to stop breach | Irreparable harm, inadequate damages |
| Reformation | Court rewrites contract | Mutual mistake or fraud |
| Rescission | Cancel contract, return to pre-contract position | Material breach, fraud, duress |
Types of Damages
- Compensatory: Actual losses (expectation, reliance, restitution)
- Consequential: Foreseeable indirect losses
- Liquidated: Pre-determined amount specified in contract
- Nominal: Token sum when breach occurred but no actual loss
- Punitive: Rare in contract law; punishment for egregious conduct
Common Challenges and Solutions
Drafting Challenges
| Challenge | Solution |
|---|---|
| Ambiguous Terms | Define key terms clearly; use examples where helpful |
| Conflicting Clauses | Review entire document for consistency; include hierarchy of documents |
| Missing Terms | Use comprehensive checklists; include “entire agreement” clause |
| Changing Circumstances | Include force majeure, renegotiation, and adaptation clauses |
Performance Challenges
| Challenge | Solution |
|---|---|
| Non-performance | Document all breaches; follow notice provisions carefully |
| Delayed Performance | Include specific timelines and consequences for delays |
| Substandard Performance | Define quality standards clearly; include inspection rights |
| Changed Conditions | Address material changes through formal amendments |
Contract Defenses
Formation Defenses
- Mistake: Mutual or unilateral error about material fact
- Misrepresentation: False statement inducing contract
- Fraud: Intentional deception
- Duress: Threat or coercion
- Undue Influence: Improper persuasion exploiting trust
Public Policy Defenses
- Illegality: Contract violates law
- Unconscionability: Unfairly one-sided terms
- Restraint of Trade: Unreasonably restricts competition
- Statute of Frauds Violation: Certain contracts not in writing

Contract Management
- Maintain centralized contract repository

Contract Negotiation
