An express trust will come to an end so soon as the time arrives at which the creator intended it should come to an end,10 an idea which is otherwise expressed by the statement that it comes to an end when the purposes of the trust are accomplished.11 So if a trust is intended to endure only during one's life, whether the life of the cestui12or of a trustee,13 it will expire on his death, and if intended to endure only so long as the cestui refrains from assigning his interest, it will terminate upon his assignment thereof.14 Likewise a trust will, it seems, come to an end when the accomplishment of the purposes thereof becomes impossible.15

Sec. 1161

Equitable Ownership.

A trust which is intended to endure only during the continuance of an equitable life interest in a cestui named will come to an end, it seems, if such life interest is merged in the remainder thereon,16 as it will if by reason of a partition each person interested acquires an estate in fee simple in possession.17

- (b) By merger. The acquisition by one person of both the legal estate of the trustee, and the beneficial interest of the cestui que trust, has in some cases the effect of terminating the trust by reason of what is referred to as the "merger" of the equitable in the legal title. Just when such merger, with the resulting termination of the trust, will occur, is however a matter as to which the cases give no satisfactory criterion.

It has been said that one cannot he trustee for himself,18 but this cannot well mean that one is incapable of being one of the trustees of a trust of which he is one of the beneficiaries. This constantly occurs,19 and to apply the doctrine of merge in such a case might.be attended with very considerable practical difficulty, as for instance, when A and B have the legal title and B, C, and D have the equitable interest. The dictum referred to has, however, an obvious application when one has the legal estate in fee simple, and also an equitable estate in fee simple, with no outstanding particular estate in favor of another. In such a case there is no person to assert any trust obligation, and that merger occurs has been several times decided.20 A like view has been taken when there were two or more trustees who are absolutely identical with the beneficiaries in fee
