[LABEO libro primo posteriorum a Iauoleno epitomatorum. ] §28.6.9.prSi pater filio impuberi eosdem quos sibi et te unum praeterea heredem instituit, bonorum filii te dimidium, ceteros patris heredes communiter dimidium ita habere, ut unus semis apud te maneat, alterius semissis pro his partibus inter heredes paternos diuisio fiat, quibus ex partibus hereditatem paternam haberent.
[LABEO, Book 1 of Epitomes of Posthumous Works by Javolenus.] If a father instituted for his impuber son the same heirs as for himself, and you alone in addition, you should have half of the son's estate, and the other heirs of the father should collectively have the other half, in such a way that one half remains with you, and the division of the other half is made among the father's heirs in proportion to those shares in which they held the father's inheritance.
