It is necessary at the outset to emphasize that the promise which has been found was no more at best than a promise to leave the appellants by will the deceased's estate at death. It is well established that such a promise does not involve an obligation not to part with any property during life: and, in any case, the primary judge did not find that a promise had been made to keep until death the assets owned at the time of the exhibition of the will, or at least any particular assets. But such a promise to leave by will does mean that no property will be disposed of in lifetime by a transaction which in substance, if not in form, is testamentary: that is to say, such a promise means that the only testamentary disposition of the property of the promisor shall be by will. A transaction by which the promisor has placed his property in the name of another and for the benefit of that other on his death, whilst really retaining it for himself in his lifetime, is for the purpose in hand a testamentary transaction which would be in breach of a promise to leave by will: see Fortescue v. Hennah [7] ; Logan v. Weinholt [9] ; Jones v. Martin [6] ; and cf. Turner v. Jennings [10] ; and In re Bennett; Bennett v. Bennett [8] . The underlying reasoning of those cases is that, whilst the promisor is free to divest himself of the property by a transaction inter vivos, he may not either enter into an illusory transaction whereby he appears, contrary to the reality, to have parted with his property, or into a transaction whereby he keeps an interest in the property during his lifetime, so arranging the transaction that the property passes on his death to the person into whose name he has transferred it. So to do is to deal with the property in a testamentary fashion in breach of the promise.
