The transferee may have the option to acquire the interest which the transferor subsequently acquires. This gives definitions of transferor, transferee and the like. The trust property is said to "result" back to the transferor (implied settlor). In each case the assets return (or result back) to the transferor. The transferor should subsequently acquire some interest in the property he had agreed to transfer. It will operate on any interest which the transferor may acquire in such property. A transferor failing upon one theory might still prevail upon the other. The transferor, however, generally has the option of a restitutionary action to recover the property. The transferor has to state what these are beforehand.
