[ULPIANUS libro uicensimo quarto ad Sabinum. ] §40.4.9.prSi quis ita legatus sit, ut manumittatur, si manumissus non fuerit, liber esse iussus est eique legetur: et libertatem competere et legatum deberi saepe responsum est.
[ULPIANUS in the twenty-fourth book on Sabinus.] If anyone has been left as a legacy on the condition that he be manumitted, and if he should not be manumitted, he is ordered to be free and a legacy is left to him: it has often been answered both that the freedom belongs to him and that the legacy is due.
§40.4.9.1Quod constitutum est uetitum in testamento ad libertatem perduci non posse manumitti, hoc ad eos pertinere puto, qui testatoris fuerunt uel heredis: seruo enim alieno id irrogari non poterit.
As to the rule established that one who is forbidden in a testament to be manumitted cannot be brought to freedom, I think this applies to those who belonged to the testator or to the heir: for such a restriction cannot be imposed on another person's slave.
