[POMPONIUS libro nono ad Sabinum. ] §18.4.1.prSi hereditas uenierit eius, qui uiuit aut nullus sit, nihil esse acti, quia in rerum natura non sit quod uenierit.
[POMPONIUS, on Sabinus, book 9.] If the inheritance of a person who is living or who does not exist should be sold, nothing is accomplished, because that which was sold does not exist in the nature of things.
