Under Dutch law, the effect of annulment of a legal act by a prejudiced creditor, is only relative. The creditor can only seek annulment to the extent that his interests have been harmed, and the annulment has no effects beyond what is strictly necessary to remedy the adverse effects to the creditor. The implication of this is that the legal act remains valid against all other creditors. However, rights acquired by third parties by virtue of an annulled legal act (other than gratuitous acts), are not affected by such an annulment. With regard to a third party who has acquired property in good faith, based on a gratuitous title, an annulment by a prejudiced creditor has no effect to the extent that this third party shows that he has not as yet derived profit from the legal act at the time the property is claimed from him.
