IV. Prescription
1 A claim in abatement prescribes one year after the date on which the heirs learned of the infringement of their rights and in any event after ten years have elapsed since the succession, in the case of testamentary disposition, or since the testator’s death, in the case of other dispositions.
2 If the declaration of the invalidity of a later disposition revives an earlier one, the prescriptive periods begin on the date on which invalidity was declared.
3 The entitlement to abatement may be invoked as a defence at any time.
