A bargain may be vitiated not only by fraud of one of the parties aimed against the other, but by the fraud of one or both aimed against the creditors of one of them. Such transactions generally relate to executed transfers, and the decisions on them, therefore, fall outside the scope of this book except in so far as they show by analogy the invalidity of an executory transaction. Where the property transferred or surrendered is a chose in action, the matter has been previously touched upon.*0 It is possible, however, for an executory agreement to be fraudulent as against creditors, and without considering what may be the rights or remedies of creditors in attacking such an agreement, it may be said that as between the parties it is an illegal agreement.91
