[IULIANUS libro uicensimo sexto digestorum. ] §38.2.13.prFilius patroni exheredatus, quamuis nepos ex eo heres scriptus fuerit, bonorum possessionem contra tabulas paternorum libertorum accipere non potest: licet enim necessarius existat patri suo, non per semetipsum, sed per alium ad hereditatem admittitur.
[IULIANUS libro uicensimo sexto digestorum.] A disinherited son of a patron, although a grandson born of him has been written as heir, cannot receive possession of goods contrary to the will of his father's freedmen; for although he may exist as a necessary heir to his own father, he is admitted to the inheritance not through himself, but through another.
et certe constat: si emancipatus filius exheredatus fuerit et seruus eius heres scriptus, etsi iusserit seruo hereditatem adire et ita patri suo heres extiterit, non habebit contra tabulas paternorum libertorum bonorum possessionem.
And indeed it is well established that if an emancipated son has been disinherited and his slave written as heir, even if he has ordered the slave to enter upon the inheritance and has thus become heir to his own father, he shall not have possession of goods contrary to the will of his father's freedmen.
