Introduction
In the English law of contract, the doctrine of consideration is a fundamental requirement for the formation of a simple contract. For a promise to be legally binding, the promisee must provide consideration in return. The statement that consideration ‘needs to be sufficient in order for it to be enforceable’ captures a core principle of this doctrine. This essay will argue that this statement is an accurate reflection of the law. It will do so by explaining the distinction the courts draw between ‘sufficient’ and ‘adequate’ consideration, using established case law to illustrate how this principle operates in practice. The essay will confirm that while consideration must have some recognisable value in the eyes of the law, the courts will not inquire into the fairness of the bargain itself.
The Distinction Between Sufficiency and Adequacy
The principle that consideration must be sufficient, but need not be adequate, is central to understanding its role in contract law. ‘Sufficiency’ refers to whether what is offered as consideration is something that the law recognises as having value. It must be something tangible, or a right, interest, or forbearance that has some economic value, however small (McKendrick, 2021). By contrast, ‘adequacy’ refers to the commercial value of the consideration in relation to the promise it is exchanged for. The courts are not concerned with whether a party has made a good or a bad deal; their role is not to assess the fairness of the exchange. This judicial reluctance to interfere with bargains is based on the principle of freedom of contract, which presumes that parties are the best judges of their own interests. Provided the consideration is legally sufficient, its adequacy is irrelevant to the question of enforceability.
Illustrating Sufficiency in Case Law
The courts have confirmed this principle in several key cases. A well-known example is Thomas v Thomas (1842) 2 QB 851, where an executor promised to allow a widow to occupy a house for the rest of her life in return for her paying £1 per year towards the ground rent and keeping the house in good repair. The court held that the £1 annual payment was clearly not adequate consideration for a life interest in a property. However, it was deemed legally sufficient because it was a promise to pay a sum of money, which has recognised economic value. Patteson J stated that "consideration must be of some value in the eye of the law".
This idea that even trivial items can constitute sufficient consideration was explored in Chappell & Co Ltd v Nestle Co Ltd [1960] AC 87. In this case, Nestlé offered to sell gramophone records to the public for a certain price plus three chocolate bar wrappers. The question for the court was whether the wrappers were part of the consideration. The House of Lords held that they were. Lord Somervell famously remarked that "A peppercorn does not cease to be good consideration if it is established that the promisee does not like pepper and will throw away the corn." This confirms that as long as the promisor has requested the item as part of the price for their promise, it does not matter that it has little or no intrinsic value to them. The wrappers were part of the deal, and were therefore sufficient.
What is Not Sufficient Consideration?
While the courts take a broad view of what is sufficient, certain things are not recognised as good consideration. For example, past consideration is no consideration. This occurs when a promise is made after an act has already been performed, as seen in Re McArdle [1951] Ch 669, where a promise to pay for home improvements made after the work was completed was held to be unenforceable. Similarly, performing a pre-existing public duty is generally not sufficient consideration for a new promise, as was established in Collins v Godefroy (1831) 1 B & Ad 950. These exceptions demonstrate that while the bar for sufficiency is low, it is not non-existent. The consideration must be given in direct exchange for the promise and must be more than what the promisee is already legally obligated to do.
Conclusion
In conclusion, the statement that consideration must be sufficient to be enforceable is a correct summary of the position in English contract law. The law insists that something of value in the eyes of the law must be exchanged, thereby establishing that a bargain has been made. However, it deliberately refrains from judging the adequacy of that value, leaving parties free to negotiate their own terms. As cases like Thomas v Thomas and Chappell v Nestle demonstrate, the threshold for sufficiency is low, but it serves the important function of distinguishing legally enforceable promises from gratuitous ones. By refusing to assess the fairness of the exchange, the courts uphold the principle of freedom of contract, ensuring certainty and respecting the autonomy of the contracting parties.
