Quick Summary of Consensual Contract

A consensual contract is a legally binding agreement between two or more parties that is formed through mutual consent and agreement. This type of contract is based on the principle that all parties involved have willingly and knowingly entered into the agreement without any coercion or duress. In order for a consensual contract to be valid, it must meet the requirements of offer, acceptance, consideration, and legal capacity. Once formed, a consensual contract is enforceable by law and can be used as a basis for legal action if one party fails to fulfil their obligations.

Full Definition Of Consensual Contract

A consensual contract is an agreement between two or more parties where all parties involved have mutually agreed to the terms and conditions stipulated within the contract. This mutual consent is the cornerstone of any legally binding agreement, ensuring that all parties are aware of their obligations, rights, and the potential consequences of non-compliance. In British law, consensual contracts are foundational to both commercial and personal transactions, underpinning the legal framework that governs contractual relationships.

Essential Elements of a Consensual Contract

For a contract to be valid under British law, it must contain several essential elements:

  • Offer and Acceptance: A contract begins with an offer by one party and the acceptance of that offer by another. The offer must be clear, definite, and communicated to the offeree, who then must accept the offer unequivocally.
  • Consideration: This is the value exchanged between the parties, which can be in the form of money, services, goods, or a promise to act or refrain from acting. Consideration must be sufficient but not adequate, meaning it must be something of value in the eyes of the law but not necessarily equal in value.
  • Intention to Create Legal Relations: Both parties must intend for their agreement to be legally binding. In commercial agreements, there is a presumption of this intention, whereas, in social or domestic arrangements, the presumption is generally against it.
  • Capacity: The parties entering into the contract must have the legal capacity to do so. This means they must be of legal age, of sound mind, and not disqualified from contracting by any law.
  • Consent: Consent must be freely given without coercion, duress, undue influence, or misrepresentation. This ensures that all parties are willingly entering into the contract.
  • Legality of Purpose: The contract’s purpose must be legal and not against public policy. Contracts involving illegal activities or purposes contrary to public policy are void and unenforceable.

Formation of Consensual Contracts


An offer is a definite promise to be bound, provided that certain terms are accepted. The offer must be communicated clearly and unequivocally to the offeree. It can be made to a specific person, a group of people, or the public at large. Offers can be revoked at any time before acceptance unless they are irrevocable offers that are supported by consideration.


Acceptance must be an unconditional agreement to all the terms of the offer. Any modification of the terms constitutes a counteroffer, which negates the original offer. Acceptance can be communicated verbally, in writing, or by conduct. The method of acceptance must follow any stipulations provided by the offeror.


Consideration is what each party brings to the table. It distinguishes a contract from a gift. In British law, consideration must be “sufficient” but need not be “adequate,” meaning it must have some value, although not necessarily equivalent to what is received in return. Past consideration (something given or promised before the promise in question) is not valid consideration.

Intention to Create Legal Relations

For a contract to be enforceable, there must be a clear intention by the parties to enter into a legally binding agreement. In commercial transactions, there is a strong presumption that the parties intend to create legal relations. In contrast, social and domestic agreements typically presume the opposite, unless clear evidence indicates otherwise.


The law requires that parties entering into a contract can do so. This includes being of legal age (18 years or older) and having sound mental faculties. Certain individuals, such as minors or those with significant cognitive impairments, are generally not bound by contractual obligations.


Consent must be genuine. If a party’s consent is obtained through misrepresentation, undue influence, duress, or mistake, the contract may be void or voidable. Genuine consent ensures that all parties have agreed to the same terms without being misled or forced.

Types of Consensual Contracts

Express Contracts

These are agreements where the terms are clearly stated, either orally or in writing. Express contracts leave little room for ambiguity, as the details of the agreement are explicitly communicated and understood by all parties involved.

Implied Contracts

Implied contracts are not written or spoken but are formed by the actions or conduct of the parties. These contracts arise from circumstances that suggest an agreement has been reached based on the behaviour of the parties involved. For instance, when a person eats at a restaurant, there is an implied contract that they will pay for the meal.

Unilateral and Bilateral Contracts

  • Unilateral Contracts: These involve a promise made by one party in exchange for the performance of an act by another party. The contract is only formed when the act is performed. An example is a reward contract, where one party promises to pay if another party finds and returns a lost item.
  • Bilateral Contracts: These involve mutual promises between parties. Each party is both a promisor and a promisee, with the contract formed at the point when the promises are exchanged. Most commercial contracts are bilateral.

Enforceability and Remedies

Valid, Void, and Voidable Contracts

  • A valid contract contains all the essential elements and is legally enforceable.
  • Void Contract: A contract that lacks one or more of the essential elements and is therefore unenforceable from the outset.
  • Voidable Contract: A contract that is valid but may be voided at the discretion of one of the parties due to specific circumstances, such as misrepresentation or undue influence.

Remedies for Breach of Contract

When a consensual contract is breached, several remedies are available to the aggrieved party:

  • Damages: Monetary compensation for losses suffered due to the breach. These can be compensatory (to cover direct losses and costs) or consequential (to cover indirect and foreseeable losses).
  • Specific Performance: A court order requiring the breaching party to perform their contractual obligations. This remedy is typically used when damages are insufficient and the subject matter of the contract is unique.
  • Injunction: A court order preventing a party from doing something that would breach the contract.
  • Rescission: Cancellation of the contract, with both parties restored to their pre-contractual positions.
  • Restitution: Return of any benefits conferred under the contract to prevent unjust enrichment.


Consensual contracts form the bedrock of British commercial and personal transactions, ensuring that agreements are based on mutual consent and legal enforceability. The essential elements—offer and acceptance, consideration, intention to create legal relations, capacity, consent, and legality—must be present for a contract to be valid. Understanding the formation, types, and enforceability of consensual contracts is crucial for navigating legal obligations and protecting one’s interests in various contractual arrangements.

In practice, parties must carefully consider these elements when drafting and entering into contracts to ensure they are legally binding and enforceable. Properly executed contracts provide clarity and security, fostering trust and cooperation in business and personal dealings.

Consensual Contract FAQ'S

A consensual contract is an agreement between two or more parties that is formed through mutual consent and understanding without any coercion or duress.

Yes, in order for a contract to be legally binding, it must be consensual. This means that all parties involved willingly and voluntarily agree to the terms and conditions of the contract.

A consensual contract can be either oral or written. While it is generally recommended to have contracts in writing to avoid any misunderstandings or disputes, oral contracts can still be legally enforceable if they meet certain criteria.

In most cases, minors (individuals under the age of 18) are not legally capable of entering into a consensual contract. However, there are exceptions for certain types of contracts, such as contracts for necessities like food, clothing, and shelter.

Yes, a consensual contract can be modified or terminated if all parties involved agree to the changes. It is important to document any modifications or terminations in writing to avoid any future disputes.

If one party fails to fulfil their obligations under a consensual contract, it is considered a breach of contract. The non-breaching party may be entitled to various remedies, such as monetary damages or specific performance (forcing the breaching party to fulfil their obligations).

Yes, if one party was forced or coerced into entering into a consensual contract, they may have grounds to have the contract cancelled or declared void. Duress or coercion undermines the voluntary nature of the agreement.

In many cases, a consensual contract can be assigned to another party with the consent of all parties involved. However, some contracts may contain provisions that restrict or prohibit assignment, so it is important to review the contract terms.

If one party lacked the mental capacity to understand the nature and consequences of the contract at the time of entering into it, the contract may be voidable. However, the determination of mental capacity can be complex and may require legal intervention.
