[AFRICANUS libro secundo quaestionum. ] §28.6.33.prSi mater ita testetur, ut filium impuberem, cum erit annorum quattuordecim, heredem instituat eique pupillaribus tabulis, si sibi heres non erit, alium substituat, ualet substitutio.
[AFRICANUS, from the Second Book of Questions.] If a mother should make her will in such a manner that she appoints her impuberate son as heir when he reaches fourteen years of age, and substitutes another for him in pupillary tablets in the event that he does not become her heir, the substitution is valid.
§28.6.33.1Si filius et ex eo nepos postumus ita heredes instituantur, ut Gallo Aquilio placuit, et nepoti, si is heres non erit, Titius substituatur, filio herede existente Titium omnimodo, id est etiam si nepos natus non fuerit, excludi respondit.
If a son and a posthumous grandson by him are appointed heirs in the manner approved by Gallus Aquilius, and Titius is substituted for the grandson in the event that he does not become heir, he answered that if the son becomes the heir, Titius is excluded in any event, that is, even if the grandson is not born.
