Renunciation has no effect if the renouncing party’s reserve estate has not been affected. If the hereditary reserve has only been partially infringed, the renunciation only produces effects up to the amount of the infringement of the renouncing party’s reserve resulting from the liberality granted. If the reserve is impaired to a greater extent than that provided for in the renunciation, the excess is subject to reduction.
A renunciation relating to the reduction of a liberality relating to a specific property lapses if the liberality impinging on the reserve does not relate to that property. The same applies if the liberality was not made for the benefit of the specified person or persons.
