What is a contract?

A contract is essentially a legally binding agreement between two or more parties. It outlines the rights, responsibilities, and obligations that each party has agreed to undertake. These agreements can take various forms, including written, verbal, or even implied by conduct.

A contract is enforceable by law. This ensures that the promises made by the contracting parties involved are upheld and that any disputes can be resolved in a court of law or through arbitration.

What is contract law?

Contract law describes the legal framework that governs these agreements. It is commonly governed by the state common law and establishes the rules for creating valid contracts, interpreting their terms, and enforcing them if necessary. This ensures fairness and predictability in business dealings and everyday transactions.

Key components of a legally enforceable contract

Not every agreement qualifies as a legally enforceable contract. A valid contract needs to have the following key components:

Offer

This is a clear and definite proposal made by one party indicating their willingness to enter into a binding agreement. It outlines the terms of the agreement, such as the service to be provided, the price, and the deadline.

Acceptance

The unequivocal agreement by the other party to the terms of the offer. This acceptance must be communicated clearly, without any additional conditions. Imagine you offer to paint your friend's house for $500. Their enthusiastic "Yes, deal!" is a clear acceptance.

Consideration

This is the value exchanged between the parties. It could be money, goods, services, or even a promise to do (or not do) something. Essentially, each party gives something up to get something in return.

Capacity

All parties involved must be legally capable of entering into a contract. This means they are of legal age (usually 18), of sound mind, and not otherwise prohibited by law from contracting. A minor entering into a contract for a car, for instance, might lack capacity.

Legality

The entire contract's purpose and terms must be legal and not violate public policy. Agreements to commit crimes or engage in illegal activities are not enforceable. Let's say somebody wants to sell illegal drugs; the contract they might draft would be void.

Mutual assent

Both parties must genuinely agree to the terms of the contract, free from any coercion, mistake, or misrepresentation. There must be a "meeting of the minds" on the material terms.

Understanding these key components is crucial when entering into any agreement. For those involved in frequent contract negotiations, it's also helpful to be familiar witheffective negotiation strategies.

Types of contracts

Contracts are the building blocks of countless agreements, big and small. But with so many variations, dealing with them can get confusing. Let's understand different types of contracts based on various categories to empower you to approach every agreement with a clearer understanding.

Based on formality

  • Formal contracts: These are typically written agreements with specific formalities, like signatures and seals. Examples include leases, loan agreements, and mortgages. These formalities provide stronger evidence of the agreement's existence and terms.
  • Informal contracts: These can be written or verbal agreements, often used in everyday transactions like buying groceries. While less formal, they can still be legally binding if they meet the key components mentioned earlier.

Based on how terms are expressed

  • Express contracts: The terms are explicitly stated, either in a written or verbal contract, and both parties clearly communicate their intentions and obligations.
  • Implied contracts: The terms are inferred from the parties' conduct. Imagine hiring a handyman for a small job without a written agreement—the terms (service for payment) are implied by your actions.

Based on mutuality of obligation

  • Bilateral contracts: Both parties have obligations under the agreement. An employment contract where you agree to work and the employer agrees to pay you is bilateral.
  • Unilateral contracts: Only one party has an obligation under the agreement. For instance, offering a reward for a lost pet creates a unilateral contract – the finder has an obligation to return the pet to claim the reward, but you (the offeror) have no obligation until the pet is returned.

Based on performance

  • Executed contracts: Both parties have already fulfilled their obligations under the agreement. For example, you've paid for a haircut, and the haircut is complete – the contract is executed.
  • Executory contracts: At least one party has yet to fulfill their obligations under the agreement. A signed lease agreement where you haven't moved in yet is an example—obligations (paying rent, occupying the apartment) still need to be performed.

Based on the subject matter

  • Employment contracts: These outline the terms of employment between an employer and employee, including salary, benefits, and job duties.
  • Business contracts: These include a variety of contracts utilized in business activities, such as partnership agreements and terms of service, ensuring proper conduct and understanding between parties.
  • Sales contracts: These are governed by the Uniform Commercial Code and address the sale of goods or services, specifying the price, delivery terms, and warranty information.
  • Service contracts: These outline the terms for professional services to be rendered, such as a contract with a web developer or a consultant.
  • Non-disclosure agreements (NDAs): These protect confidential information shared between parties.
  • Real estate contracts: These govern the purchase or sale of real property and outline the terms of the transaction.

Note: This is not an exhaustive list, and there can be some overlap between these categories. The specific type of contract you encounter will depend on the situation and the nature of the agreement.

When contracts can't be enforced

Even the most well-intentioned contracts can fall short and become unenforceable in court. Here are some reasons why a seemingly valid agreement might not hold up:

Contracts lacking capacity

Capacity refers to a party's legal ability to enter into a binding contract. This means they must be of legal age (18 or above), of sound mind, and not otherwise prohibited by law from contracting. For example, a minor cannot enter into a binding contract to purchase a car. Similarly, a person deemed mentally unfit to understand the agreement's terms wouldn't have the necessary capacity.

Contracts with fraudulent misrepresentations

A contract formed through deception can be voidable. This occurs if one party makes a false statement (material misrepresentation) that induces the other party to enter the agreement. The deceived party can then choose to void the contract, essentially canceling it.

Imagine being convinced to buy a car based on false mileage information – a clear case of fraudulent misrepresentation.

Contracts with ambiguous terms

If a contract's terms are unclear and can be interpreted in multiple ways, a court might not be able to enforce it. Ambiguity can lead to disputes about what the parties actually agreed to. To avoid this, ensure your contracts use clear and concise language, leaving no room for misinterpretations.

Contracts that violate public policy

Agreements that promote illegal activities or go against the public good will not be enforced. For instance, a contract to rig a sporting event is not only unethical but also unenforceable. Public policy sets the boundaries for acceptable agreements, ensuring contracts don't undermine societal interests.

Contracts vs. agreements

It's important to distinguish between a contract and a simple agreement. Not all agreements are legally binding contracts, so here's the key difference:

  • Contracts: As we've discussed, contracts are legally enforceable agreements with the key components mentioned above (offer, acceptance, consideration, etc.). If one party breaches a contract, the other party can seek legal recourse, like suing for damages.
  • Agreements: Agreements are broader and can be informal understandings between parties. For example, agreeing to split a pizza with a friend isn't a legally binding contract. There's no formal offer, acceptance, or consideration involved. It's simply a friendly understanding.

Think of a contract as a formal document, while an agreement is a more casual understanding.

What is considered a breach of contract?

A breach of contract occurs when one party fails to fulfill their obligations as outlined in the agreement. This could be failing to deliver a product, perform a service, or make a payment on time.

If a breach occurs, the non-breaching party has options. They can sue for damages (compensation for the loss they suffered), seek to have the contract enforced by the court, or even terminate the agreement altogether.

Fundamental legal principles in contract interpretation

Even with a seemingly clear contract, disagreements can arise about what the terms actually mean. Courts rely on specific legal principles to interpret contracts and determine the intent of the parties involved. Here are some fundamental principles you should know:

Plain meaning rule

Generally, courts will interpret the contract based on the plain meaning of the words used. The assumption is that parties with common sense would understand the terms the same way. Let's say a contract states, "Payment to be done in 30 days." The plain meaning rule would be applied here, suggesting payment is due within 30 days of the contract signing.

Contra proferentem

This principle comes into play when a term in the contract is ambiguous. In such cases, the ambiguity is interpreted against the party who drafted the term. This encourages clearer and more precise drafting by placing the burden on the party who wrote the contract to ensure clarity.

Imagine a contract drafted by a contractor that contains unclear language about what materials are included in the project. Contra proferentem might be used to interpret the ambiguity in favor of the homeowner, requiring the contractor to provide a wider range of materials.

Parol evidence rule

This rule generally prevents the introduction of evidence outside the written contract to change its meaning. The purpose is to promote reliance on the written document as the final and complete agreement between the parties. However, there are exceptions to this rule, such as situations where fraud or mistake is alleged.

For instance, if a written contract accidentally states the wrong price for a product, parol evidence might be allowed to introduce evidence of the correct price discussed during negotiations.

Implied terms

In some cases, courts may imply terms into a contract that are not explicitly stated but are necessary to make the agreement work as intended. These implied terms are based on what a reasonable person would believe to be part of the agreement under the circumstances.

Imagine a contract for a web development project that doesn't mention website maintenance. An implied term might be that the developer is responsible for basic maintenance for a certain period after launch.

These principles guide how courts interpret contracts. However, in day-to-day business, many potential disputes can be avoided through careful contract review and redlining. For best practices in this area, you might find this guide on how to redline documents helpful.
