[PAULUS libro octauo ad Plautium. ] §33.5.13.prSi optio serui data mihi fuerit et Sticho aliquid testator sine libertate legasset, tunc sequens legatum consistit, cum tota familia ad unum, id est Stichum recciderit, ut quasi pure legato utiliter sit legatum.
[PAULUS, Book VIII on Plautius.] If the choice of a slave has been given to me, and the testator had bequeathed something to Stichus without freedom, then the subsequent bequest stands when the entire household of slaves has been reduced to one, that is, Stichus, so that it is validly bequeathed as if it were an unconditional bequest.
nec aduersatur Catoniana, si uoluntarius heres institutus sit, quia potest ante aditam hereditatem, etiamsi statim decesserit, familia minui: quod si necessarius heres institutus sit, sequens legatum propter Catonianam inutile est.
The Catonian rule is not opposed to this if a voluntary heir has been appointed, because before the inheritance is entered upon, even if the testator dies immediately, the household of slaves can be reduced; but if a necessary heir has been appointed, the subsequent bequest is void on account of the Catonian rule.
§33.5.13.1Pomponius scribit emptore hereditatis postulante, ut is, cui serui optio legata sit, optet, uidendum esse, an praetor ut id faciat cogere debeat legatarium, quemadmodum si heres institutus id postularet, quia potest per heredem id emptor consequi: et quare non possit, non uideo.
Pomponius writes that when the buyer of an inheritance demands that the person to whom the choice of a slave was bequeathed should make the choice, it must be considered whether the praetor ought to compel the legatee to do so, just as if the appointed heir demanded it, because the buyer can attain this through the heir; and I do not see why it should not be possible.
