Dillwyn v Llewelyn [1862] EWHC Ch J67; 45 ER 1285
Incomplete gifts and interests in land.
Facts
A father signed a memorandum leaving his farm to his son. However, this memorandum was not executed by deed. The plaintiff took possession of the land and built a dwelling upon it at a considerable expense. This was done with the knowledge and approval of the father. However, the father died without ever transferring the legal estate to his son. The plaintiff then claimed an equitable interest in the property from his father’s executor.
Issues
The memorandum did not satisfy the formalities required to pass an estate in land. The courts normally treated such a promise as an imperfect gift, and equity will not assist a mere donee who has given no consideration for such a promise by perfecting a gift if it failed.
Decision/Outcome
The court found in favour of the plaintiff. This was not merely an incomplete gift. The father had made an assurance that the son would receive the fee simple, and in reliance upon this the son had spent a considerable amount of money. Lord Westbury held that a donor’s subsequent acts may give a donee rights which he did not acquire from the original gift. He said the current case was analogous to part performance of a contract; in spending money, the son had provided valuable consideration. Equity acts upon what is done not the language of a memorandum. There was a clear intention to convey the fee simple to the plaintiff. Therefore, the court ordered the defendant to convey the freehold to the plaintiff.

This article accurately summarises the facts, issues, and outcome of Dillwyn v Llewelyn [1862] EWHC Ch J67. The case remains good law and continues to be cited as a foundational authority in proprietary estoppel, establishing that expenditure in reliance on an assurance can give rise to an equity that courts will satisfy by compelling conveyance of the relevant interest in land. Readers should note, however, that the doctrinal framework surrounding proprietary estoppel has developed considerably since 1862. The modern requirements — assurance, reliance, and detriment — were consolidated in cases such as Thorner v Major [2009] UKHL 18, and the question of how courts should satisfy the equity (including whether the remedy must be proportionate to the detriment rather than necessarily fulfilling the expectation) has been addressed in subsequent case law, most recently examined in Guest v Guest [2022] UKSC 27. The Supreme Court in Guest confirmed that the court retains a broad discretion in fashioning a remedy, though expectation-based relief remains available. Nothing in these later developments renders this article’s account of Dillwyn v Llewelyn itself inaccurate, but students should read the case alongside modern proprietary estoppel authorities for a complete picture of the current law.
