A trust is said to be executory where some further act is requisite to be done by the author of the trust himself or by the trustees, to give it its full, effect; as, in the case of marriage articles; or, as in the case of a will, where, property is vested in trustees in trust to settle or convey.; for, it is apparent in both of these cases, a further act, namely, a settlement or a conveyance, is contemplated. 2. The difference between an executed and an executory trust, is this, that courts of equity in cases of executed trusts will construe the limitations in the same manner as similar legal limitations. White’s L. C. in Eq. 18. But, in cases of executory trusts, a court of equity is not, as in the case of executed trusts, bound to construe technical expressions with legal strictness, but will mould the trusts according to the intent of the creator of such trusts White’s L. C. Eq. 18. 3. When a voluntary trust is executory, and not executed, if it could not be enforced at law, because it is a defective conveyance, it is not helped in equity, in favor of a volunteer.
