Introduction
Contracts are the foundation of virtually every business and personal transaction — from buying a car to signing a lease to hiring a contractor. Understanding the basics of contract law can help you protect yourself, recognize when your rights have been violated, and make informed decisions before you sign on the dotted line. This guide provides a plain-language overview of how contracts work and what makes them legally enforceable.
What is a Contract?
A contract is a legally binding agreement between two or more parties that creates mutual obligations enforceable by law. When one party fails to fulfill their obligations under a contract it is called a breach of contract and the other party may be entitled to damages or other legal remedies.
Essential Elements of a Valid Contract
For a contract to be legally enforceable it must contain the following essential elements:
1. Offer
One party must make a clear and definite offer to do something — or to refrain from doing something — in exchange for something from the other party. The offer must be specific enough that the other party knows exactly what is being proposed.
2. Acceptance
The other party must clearly accept the offer on the exact terms offered. A counteroffer — where the responding party proposes different terms — is not an acceptance but a rejection of the original offer and a new offer in its place.
3. Consideration
Consideration is something of value exchanged by each party. It is what each party gives up or promises in exchange for what they receive. Consideration can be money, goods, services, a promise to act, or a promise to refrain from acting. A contract without consideration — a pure gift — is generally not legally enforceable.
4. Mutual Assent
Both parties must genuinely agree to the terms — also called a “meeting of the minds.” A contract entered into under duress, fraud, misrepresentation, or undue influence may be voidable.
5. Capacity
Both parties must have the legal capacity to enter into a contract. Minors (under 18), people who are mentally incapacitated, and people who are intoxicated generally lack the legal capacity to enter into enforceable contracts.
6. Legality
The subject matter of the contract must be legal. A contract to perform an illegal act is not enforceable.
Do Contracts Have to Be in Writing?
Not always — many oral contracts are legally enforceable. However certain types of contracts are required by law to be in writing to be enforceable. This requirement is known as the Statute of Frauds and typically applies to:
- Contracts for the sale of real estate
- Contracts that cannot be performed within one year
- Contracts for the sale of goods worth $500 or more (under the Uniform Commercial Code)
- Contracts to pay someone else’s debt
- Prenuptial agreements
- Contracts made in consideration of marriage
Even when not legally required, putting a contract in writing is always advisable. Written contracts provide clear evidence of the terms agreed upon and are far easier to enforce than oral agreements.
Types of Contracts
Express Contract
The terms are explicitly stated — either orally or in writing. Most formal contracts are express contracts.
Implied Contract
The terms are not explicitly stated but are implied by the conduct of the parties or the circumstances. For example when you go to a restaurant and order a meal, an implied contract exists that you will pay for the food.
Unilateral Contract
One party makes a promise in exchange for a specific act by the other party. The contract is formed when the act is performed. A reward offer is a classic example — “I will pay $500 to whoever finds my lost dog.”
Bilateral Contract
Both parties exchange promises. This is the most common type of contract — for example a purchase agreement where the buyer promises to pay and the seller promises to deliver goods.
Adhesion Contract
A standard form contract drafted by one party (typically a business) that the other party must accept as-is with no opportunity to negotiate. Terms of service agreements, insurance policies, and cell phone contracts are common examples. Courts may refuse to enforce adhesion contract terms that are unconscionable or unreasonably one-sided.
What is a Breach of Contract?
A breach of contract occurs when one party fails to fulfill their obligations under the contract without a legally valid excuse. Breaches can be:
- Material breach — a significant failure that defeats the purpose of the contract and entitles the non-breaching party to cancel the contract and sue for damages
- Minor breach — a partial failure that does not defeat the purpose of the contract — the non-breaching party can sue for damages but must still perform their own obligations
- Anticipatory breach — one party indicates in advance that they will not perform their obligations, allowing the other party to treat the contract as breached immediately
Remedies for Breach of Contract
Compensatory Damages
The most common remedy — monetary compensation designed to put the non-breaching party in the position they would have been in had the contract been performed.
Specific Performance
A court order requiring the breaching party to perform their contractual obligations. Most commonly used in real estate contracts where the property is unique and money damages are inadequate.
Rescission
The contract is cancelled and both parties are restored to their original positions as if the contract never existed.
Liquidated Damages
Some contracts specify in advance the amount of damages to be paid in the event of a breach. These are called liquidated damages clauses and are enforceable if the amount is a reasonable estimate of actual damages.
Common Contract Clauses to Watch For
- Arbitration clause — requires disputes to be resolved through arbitration rather than court
- Non-compete clause — restricts one party from competing with the other after the contract ends
- Indemnification clause — requires one party to compensate the other for certain losses or damages
- Force majeure clause — excuses performance in the event of extraordinary circumstances beyond a party’s control
- Limitation of liability clause — caps the amount of damages one party can recover from the other
- Automatic renewal clause — automatically renews the contract unless one party gives notice of cancellation
Tips for Protecting Yourself in Contracts
- Always read the entire contract before signing — never sign something you have not read
- Never sign under pressure — take time to review and ask questions
- Get all promises and representations in writing — verbal assurances are difficult to enforce
- Keep a signed copy of every contract you enter into
- For significant contracts have an attorney review before you sign
- Understand your termination and cancellation rights
