Article 330. Relative nullity of a juridical act
(1) Relative nullity may be relied upon solely by the person in whose interest it is provided for or its successors, by the legal representative or by the unsecured creditors of the protected party by way of indirect action. A court may not rely on it on its own motion.
(2) Relative nullity can be cured by express or implied consent of the person in whose interest nullity is provided for. Consent to confirm a voidable juridical act must be certain and evident, and be expressed at a time when the person knew or ought to have known the ground of nullity.
(3) To confirm a voidable juridical act consent needs not be expressed in the form required for the entry into such juridical act.
(4) If both parties may rely on relative nullity of a juridical act or if several persons may seek avoidance, the confirmation of a juridical act by a person does not preclude the others to rely on nullity.
