[MARCELLUS Apud IULIANUM libro uicensimo nono digestorum notat. ] §28.5.5.prSi eiusmodi sit condicio, sub qua filius heres institutus sit, ut ultimo uitae eius tempore certum sit eam existere non posse et pendente ea decedat, intestato patri heres erit, ueluti 'si Alexandriam peruenerit, heres esto': quod si etiam nouissimo tempore impleri potest, ueluti 'si decem Titio dederit, heres esto', contra puto.
[MARCELLUS Apud IULIANUM libro uicensimo nono digestorum notat.] If the condition under which a son was instituted heir is of such a kind that at the last moment of his life it is certain that it cannot be fulfilled, and he dies while it is pending, he will be heir to his intestate father; for example, 'if he shall have reached Alexandria, let him be heir.' But if it can be fulfilled even at the very last moment, for example, 'if he shall have given ten to Titius, let him be heir,' I think the contrary.
