Without prejudice to damages, an heir who has concealed property or rights from an estate or concealed the existence of a co-heir is deemed to accept the estate purely and simply, notwithstanding any renunciation or acceptance up to the amount of the net assets, without being able to claim any share in the property or rights misappropriated or concealed. The rights accruing to the concealed heir and which have or could have increased those of the author of the concealment are deemed to have been concealed by the latter.
Where the concealment has concerned a gift that can be reported or reduced, the heir must report or reduce this gift without being able to claim any share in it.
The heir who has concealed is required to return all the fruits and income produced by the property concealed of which he has had enjoyment since the opening of the succession.
