The case of Thomas v Thomas (1842) 2 QB 851 is a foundational authority in the English law of contract, primarily concerning the doctrine of consideration. It provides a clear illustration of the legal principle that consideration must be sufficient but need not be adequate. It also establishes a crucial distinction between a promisor's motive for making a promise and the consideration required to make that promise legally enforceable. This note will outline the central issue in the case, provide a summary of the facts, and explain the court’s judgment.

The Issue

The central legal issue before the court in Thomas v Thomas was whether a legally binding contract had been formed between Mrs Thomas and the executors of her late husband's estate. Specifically, the question was whether the promise made by Mrs Thomas to pay £1 per annum towards the ground rent and to keep the property in good repair constituted sufficient consideration to support the executors’ promise to allow her to occupy the house for the rest of her life. The defendant argued that the agreement was a voluntary gift made in respect of the deceased husband's wishes and that the widow's promises were not of sufficient value to create a contract. Therefore, the court had to determine if the agreement was an unenforceable gratuitous promise or a valid contract supported by good consideration.

Basic Facts of the Case

Before his death, John Thomas orally expressed his desire that if his wife, Eleanor Thomas, survived him, she should be allowed to have the house in which they lived and its contents for the rest of her life. This wish was not included in his formal will. After Mr Thomas's death, the executors of his estate, which included his brother Samuel Thomas (the defendant), were aware of the deceased's desire.

In recognition of this, the executors entered into a written agreement with Mrs Thomas. The agreement stated that "in consideration of such desire" of the late Mr Thomas, the executors would convey the house to Mrs Thomas for her life. The agreement also stipulated that Mrs Thomas would pay the executors the sum of £1 per year towards the ground rent and that she would keep the premises in "good and tenantable repair". For some time, Mrs Thomas complied with these terms. However, Samuel Thomas later refused to complete the conveyance of the life interest and brought an action for possession to evict her, claiming the agreement was not supported by consideration.

The Judgement of the Thomas v Thomas case

The Court of Queen's Bench found in favour of Mrs Thomas, holding that a binding contract was in place. The court’s judgment systematically dismantled the defendant's arguments and clarified the nature of consideration.

Patteson J delivered the leading judgment. He explicitly stated that the motive for the promise was not the same as the consideration. The executors’ respect for the deceased's wishes was the motive for entering the agreement, but it was not the legal consideration. He stated, “Motive is not the same thing with consideration. Consideration means something which is of some value in the eye of the law, moving from the plaintiff” (Thomas v Thomas, p 859).

The court held that the widow's promise to pay £1 annually and to keep the property in repair was something of value in the eyes of the law. This promise was a detriment to her and a benefit to the estate. While £1 per year for a house was clearly not a commercially adequate rent, the court confirmed that it is not its role to assess the adequacy of the consideration. As long as the consideration is tangible and has some economic value, it will be deemed sufficient (McKendrick, 2022). The undertaking to perform repairs was also a clear legal detriment.

Coleridge J agreed, stating that the executors were bound by their express promise. He affirmed that courts should not "inquire whether the consideration is adequate, or not" (Thomas v Thomas, p 859). The agreement to pay rent and undertake repairs was sufficient to make the executors' promise to allow her to occupy the house legally binding. The court, therefore, gave judgment for the claimant, Mrs Thomas, preventing her eviction.
