AQA A-Level Law | Free Revision Notes

Estimated study time: 30–40 minutes

Contract law is concerned with legally enforceable agreements and the rights and obligations that arise from them. This The nature of contract law A-Level Law revision page introduces the structure of the AQA contract law course, including formation, contractual terms, vitiating factors, discharge and remedies. It also examines the central role of agreement in contractual liability. This overview provides the foundation for later study of freedom of contract [Freedom of contract] and the detailed rules governing individual contractual disputes.

Revision Notes 📚

The nature of contract law A-Level Law revision: what does contract law cover?

Contract law governs agreements that the law recognises as creating enforceable rights and obligations between parties.

It is part of civil law, so a contractual dispute normally involves one party bringing a civil claim against another rather than a criminal prosecution. Your earlier understanding of the distinction between criminal and civil liability [Criminal law and civil law] therefore provides useful background.

For AQA, contract law is organised around five broad areas:

1. Formation

2. Terms

3. Vitiating factors

4. Discharge

5. Remedies

A contractual problem may involve one or several of these areas. AQA specifically requires rules and principles concerning formation, terms, vitiating factors, discharge and associated remedies.

The basic structure of contractual liability

A useful way to understand contract law is to see a contract as moving through a series of possible stages.

Stage	Central question	AQA content
Formation	Has an enforceable contract been created?	Offer and acceptance, consideration and intention to create legal relations
Terms	What obligations have the parties undertaken?	Express and implied terms, conditions, warranties, innominate terms, statutory terms and exclusion clauses
Vitiating factors	Is there something wrong with the way the agreement was obtained?	Misrepresentation and economic duress
Discharge	Have the contractual obligations come to an end?	Performance, actual breach, anticipatory breach and frustration
Remedies	What legal response is available?	Compensatory damages, specific performance, rescission, termination and relevant consumer remedies

These categories provide a framework for analysing contractual scenarios.

A scenario should not automatically be treated as a formation problem merely because a contract is involved. If the facts clearly establish that a contract exists, the important issue may instead concern its terms, a vitiating factor, discharge or the appropriate remedy.

Contract formation

Before contractual rights can normally be enforced, there must first be a valid contract.

AQA identifies three essential requirements:

• offer and acceptance

• consideration, including privity of contract

• intention to create legal relations

The first of these establishes whether the parties have reached the necessary agreement.

Later lessons examine the distinction between offers and invitations to treat [Offers and invitations to treat], the rules governing acceptance [Acceptance], consideration and intention to create legal relations in much greater detail.

Agreement

An agreement is established through offer and acceptance.

In basic terms:

• one party makes an offer

• the other party validly accepts that offer

• the offer and acceptance together establish agreement between them.

AQA requires students to consider offers, offers in unilateral contracts, invitations to treat and acceptance, including communication issues.

Agreement is therefore one of the foundations of contractual liability.

However, agreement is not the same thing as a complete enforceable contract.

The existence of agreement must be considered alongside the other formation requirements of consideration and intention to create legal relations.

For example, two people may appear to agree that one will do something for the other. That does not automatically prove that a legally enforceable contract exists. The remaining formation requirements must also be satisfied where they are genuinely in issue.

Why agreement is central to contract law

The importance of agreement reflects the voluntary nature of contract law.

Contractual obligations generally arise because parties have entered into an arrangement under which particular obligations are undertaken. This connects directly to the theory of freedom of contract [Freedom of contract], which considers the importance of parties being able to determine the contractual obligations they accept.

Agreement helps establish:

• who the parties are

• what has been agreed

• whether negotiations have produced a contract

• the point at which contractual obligations may begin.

This means that accurately identifying an offer and an acceptance can determine whether contractual liability exists at all.

Agreement must be distinguished from negotiations

Not every communication made while people are negotiating creates contractual obligations.

The AQA specification distinguishes between:

• an offer

• an offer in a unilateral contract

• an invitation to treat

• an acceptance.

This distinction matters because contractual liability depends upon the legal effect of what the parties have said or done.

For example, identifying something merely as an invitation to negotiate when it is actually an offer, or treating a continuation of negotiations as an acceptance, may lead to an incorrect conclusion about whether a contract was formed.

The detailed rules are developed later in offer [Offer] and acceptance [Acceptance].

Consideration and intention to create legal relations

Agreement is only part of formation.

Consideration

Consideration concerns what is supplied in connection with the promises made under the contract.

The specification also connects consideration with privity of contract and, within the theory of contract law, with economic duress.

The detailed rules governing consideration are covered in consideration [Consideration].

Intention to create legal relations

Parties must also have the necessary intention to create legal relations.

This requirement distinguishes agreements intended to produce legal consequences from arrangements that are not intended to be legally enforceable.

Therefore:

Agreement + consideration + intention to create legal relations → the essential requirements of contract formation

This is a useful conceptual structure, although each requirement has its own detailed legal rules.

Contractual terms

Once a contract exists, the next issue may be what the parties are legally required to do.

These obligations are found in the terms of the contract.

AQA requires knowledge of:

• express terms

• implied terms

• conditions

• warranties

• innominate terms.

An express term is expressly included in the parties' agreement.

An implied term forms part of the contract even though it has not been expressly stated in the same way.

You will develop this distinction in express and implied terms [Express and implied terms].

The classification of a term is important because it can affect the consequences of its breach.

AQA also requires statutory terms imposed on certain consumer contracts by the Consumer Rights Act 2015, covering contracts to supply goods and contracts to supply services.

At this introductory stage, remember the central distinction:

Formation asks whether a contract exists. Terms determine what the contract requires.

Exclusion and limitation clauses

The specification also includes exclusion and limitation clauses.

These are contractual terms through which a party may seek to exclude or restrict liability.

AQA requires students to study:

• their nature

• common law controls concerning incorporation

• construction in outline

• statutory controls.

Their effectiveness therefore cannot simply be assumed because they appear in a document connected with a transaction.

This topic develops the wider issue of determining exactly which contractual obligations and liabilities the parties have undertaken.

Vitiating factors

A contract may appear to have been validly formed but still be affected by a vitiating factor.

AQA specifies two:

• misrepresentation

• economic duress.

A vitiating factor concerns a problem affecting the contractual relationship rather than simply asking whether offer and acceptance took place.

For example, misrepresentation [Misrepresentation: nature] concerns a situation where the required elements of a misrepresentation are established in connection with entry into the contract.

Economic duress concerns improper economic pressure affecting contractual consent.

The important distinction at this stage is:

• formation asks whether the required elements of a contract exist

• vitiating factors ask whether an apparent contractual agreement has been affected by misrepresentation or economic duress.

Discharge of a contract

Discharge concerns the ending of contractual obligations.

AQA requires three broad areas:

• performance

• breach

• frustration.

Performance

A contract may be discharged because the contractual obligations have been performed.

This is explored fully in performance [Performance].

Breach

AQA distinguishes between:

• actual breach

• anticipatory breach.

A breach occurs where contractual obligations are not performed as required. Anticipatory breach involves a refusal to perform before performance is due.

Frustration

A contract may also be discharged through frustration where the requirements of the doctrine are satisfied.

These are different legal routes to discharge, so they should not be treated as interchangeable.

Contractual remedies

Identifying a legal wrong is not always the end of a contract problem. The claimant's practical concern will often be the remedy available.

AQA specifies:

• compensatory damages

• specific performance

• rescission

• termination of the contract for breach.

The specification also requires relevant statutory consumer remedies under the Consumer Rights Act 2015.

Compensatory damages

Contractual damages are designed to compensate for recoverable loss resulting from breach.

AQA requires knowledge of:

• categories of recoverable loss

• causation

• remoteness

• mitigation.

These principles are developed later in compensatory damages and recoverable loss [Compensatory damages and recoverable loss].

Specific performance

Specific performance is an equitable remedy that may require the party in breach to perform the contractual obligation.

Rescission

Rescission is an equitable remedy associated with matters such as vitiating factors. It must not simply be used as another word for every situation in which a contract ends.

Termination for breach

A sufficiently serious breach may allow the innocent party to treat the contract as at an end.

This is distinct from rescission.

Putting the areas together

A strong way of approaching contract law is to ask questions in a logical sequence:

1. Formation: Was there a valid contract?

2. Terms: What obligations did the contract contain?

3. Vitiating factors: Was the agreement affected by misrepresentation or economic duress?

4. Discharge: Have the contractual obligations been discharged?

5. Remedies: What legal response is available?

Not every scenario requires all five stages.

For example, imagine that the facts expressly tell you that A and B entered into a valid contract and then ask whether B's refusal to perform amounts to breach. There is little value in spending most of the answer proving offer, acceptance, consideration and intention. The relevant focus is breach and its consequences.

By the end of the contract unit, you will combine these areas when tackling synoptic contractual scenarios [Synoptic contract problems].

Contract law comes from different legal sources

The rules of contract law are not contained in one single code.

Contract law contains rules derived from both:

• common law

• statute law.

This links back to your earlier study of sources of law [Sources of law].

For example, the specification expressly requires statutory rules contained in the Consumer Rights Act 2015 and the Unfair Contract Terms Act 1977, alongside wider contractual principles developed through common law.

The important examination point is to identify and apply the relevant rule rather than assume that all contract law comes from either legislation or judicial decisions alone.

Key Words 🔑

Key word	Student-friendly definition	How it may be used in an exam
Contract	A legally enforceable agreement creating rights and obligations between parties.	Used when deciding whether contractual rights or liabilities exist.
Agreement	The element of formation established through offer and acceptance.	Used when analysing communications between parties to determine whether they reached agreement.
Vitiating factor	A factor that affects an apparently formed contract, such as misrepresentation or economic duress.	Used to identify why an apparent contractual agreement may be legally affected.
Discharge	The ending of contractual obligations through a recognised method such as performance, breach or frustration.	Used when explaining whether parties remain bound by contractual obligations.
Remedy	A legal response available where contractual rights have been affected.	Used when advising a claimant about the practical consequences of establishing liability.

Hints from the Examiner Reports 💡

Examiner hint: Identify the particular contractual issue before writing. AQA examiner reports repeatedly warn that students can waste substantial time rehearsing every element of formation when the question is actually about one specific issue, such as agreement, breach or discharge.

Examiner hint: Follow the wording of the question closely. Where a question tells you to focus on agreement, there is normally no credit in lengthy discussion of consideration and intention to create legal relations unless those matters genuinely become relevant.

Examiner hint: Analyse the sequence of events rather than simply listing legal rules. Stronger responses to agreement problems have considered alternative interpretations of negotiations and then reached supported conclusions. Weaker answers have often introduced rules in a confused order without developing a coherent argument.

Examiner hint: Use contractual terminology precisely. In particular, rescission should not be used as a general synonym for ending a contract after breach. Rescission and termination for breach are legally distinct.

Examiner hint: Do not stop at liability when a scenario also requires remedies. Examiner reports emphasise that students should consider the practical remedy available rather than simply writing that the claimant can "claim damages" without further explanation.

Common Mistakes ⚠️

Mistake: Assuming that agreement alone creates a contract

Why this is incorrect: Agreement through offer and acceptance is an essential element of formation, but AQA also requires consideration and intention to create legal relations.

How to improve: When formation is genuinely in issue, work systematically through the relevant formation requirements rather than stopping after identifying offer and acceptance.

Mistake: Discussing formation in every contract problem

Why this is incorrect: A scenario may already make it clear that a contract exists. The real issue might concern its terms, a vitiating factor, discharge or remedies.

How to improve: Read the instruction first. Identify the specific legal issue before deciding which rules need to be explained and applied.

Mistake: Treating every contractual problem as the same type of issue

Why this is incorrect: Formation, terms, vitiating factors, discharge and remedies perform different functions within contract law.

How to improve: Ask what stage of the contractual relationship the facts concern. Is the question about creating the contract, determining its obligations, a problem with consent, ending obligations or responding to a legal wrong?

Mistake: Calling any ending of a contract "rescission"

Why this is incorrect: Rescission is a specific equitable remedy. It is not another name for termination following breach.

How to improve: Use the precise legal concept required by the facts. Keep rescission, termination for breach and discharge by frustration clearly separate.

Mistake: Listing rules without applying them

Why this is incorrect: Scenario questions assess your ability to use legal rules to resolve the facts, not simply reproduce notes.

How to improve: After stating each relevant rule, connect it immediately to the facts and explain what that connection suggests about the parties' rights and liabilities.

Maximum: 5 marks

Question 5

Indicative content:

Formation concerns whether a legally enforceable contract has been created and includes offer and acceptance, consideration and intention to create legal relations.

Discharge concerns how contractual obligations come to an end. AQA requires performance, breach and frustration.

A strong answer clearly distinguishes creating contractual obligations from ending them.

Maximum: 5 marks

Question 6

Indicative content:

• Priya and Rowan apparently have agreement.

• Agreement is established through offer and acceptance.

• A conclusion should recognise that agreement by itself is insufficient to establish all the essential requirements of formation.

Maximum: 5 marks

Question 7

Indicative content:

The three principal areas are:

1. Vitiating factors, because Sasha alleges misrepresentation.

2. Discharge/breach, because Theo has refused to perform a contractual obligation.

3. Remedies, because Sasha wants to know the legal response available.

Higher marks require explanation of how each area relates to the facts rather than simply naming the categories.

A well-structured answer should avoid unnecessarily reconsidering all the rules of formation because the facts state that Sasha and Theo have entered into a contract.

Maximum: 10 marks

Question 8

Indicative content may include:

• Agreement is an essential aspect of contract formation.

• Agreement is established through offer and acceptance.

• It reflects the voluntary basis on which contractual obligations arise.

• Agreement alone does not establish every requirement for an enforceable contract because consideration and intention to create legal relations must also be considered.

• Once a contract exists, disputes may concern its express or implied terms.

• A contract may be affected by a vitiating factor such as misrepresentation or economic duress.

• Obligations may subsequently be discharged through performance, breach or frustration.

• A dispute may finally require consideration of an appropriate contractual remedy.

• Strong answers should recognise that the particular facts and wording of the question determine which areas actually require analysis.

Maximum: 10 marks

A high-level response will develop a clear line of reasoning showing that agreement is fundamental to formation but forms only one part of the wider system through which contract law establishes obligations, regulates their performance and provides remedies when contractual rights are affected.
