Enforcement of Uses
The Court of Chancery eventually assumed the task of enforcing uses. Later, it decided that not only was the conscience of the feoffee to uses bound by the use, but also the conscience of his heir. Thus, on the death of the feoffee to uses the use could be enforced against the feoffee's heir to whom the legal fee simple estate had descended.
The idea of a tie in conscience was gradually extended, and with it the sphere of enforceability of the use. The modern position was reached by the beginning of the sixteenth century: The use could be enforced against anyone in the world acquiring an interest in the land other than a bona fide purchaser of the legal estate for value without notice of the use. In a conveyance "to A and his heirs to the use of B and his heirs", the common law took cognisance only of A and went no further. But if A attempted to act inconsistently with the dictates of his conscience, the Court of Chancery would enforce the use against him.
From this time, two different kinds of interests in the land could exist side by side, a fragmentation between legal and beneficial.
