An heir who renounces the succession may, however, retain the inter vivos gift or claim the legacy made to him up to the available portion unless the disposing person has expressly required the report in the event of renunciation.
In this case, the report is made in value. Where the value reported exceeds the rights he should have had in the partition if he had participated in it, the renouncing heir compensates the accepting heirs up to the amount of this excess.
