Implied trusts are those which are created by law without any express words on the part of the settlor creating them. Implied trusts are subdivided into resulting trusts and constructive trusts. In the case of resulting trusts, the law presumes that the parties intended to create a trust, and that therefore it is merely carrying out the intention of the parties, which they failed to express. In the case of constructive trusts, the law creates the trust, against the intention of the parties, in order to prevent fraud or injustice.
