[PAULUS libro octauo decimo ad edictum. ] §45.1.76.prSi stipulatus fuerim 'illud aut illud, quod ego uoluero', haec electio personalis est, et ideo seruo uel filio talis electio cohaeret: in heredes tamen transit obligatio et ante electionem mortuo stipulatore.
[PAULUS, On the Edict, Book 18] If I have stipulated for 'this or that, whichever I shall wish', this choice is personal, and therefore such a choice is inherent in the slave or the son; nevertheless, the obligation passes to the heirs even if the stipulator dies before the choice.
§45.1.76.1Cum stipulamur 'quidquid te dare facere oportet', id quod praesenti die dumtaxat debetur in stipulationem deducitur, non (ut in iudiciis) etiam futurum: et ideo in stipulatione adicitur uerbum 'oportebit' uel ita 'praesens in diemue'.
When we stipulate for 'whatever you ought to give or do', only that which is owed on the present day is brought into the stipulation, and not also (as in legal proceedings) what is future; and therefore in the stipulation, the word 'it shall be owed' or 'immediately or on a specified day' is added.
hoc ideo fit, quia qui stipulatur 'quidquid te dare oportet' demonstrat eam pecuniam quae iam debetur: quod si totam demonstrare uult, dicit 'oportebitue' uel ita 'praesens in diemue'.
This is done because he who stipulates for 'whatever you ought to give' points to that money which is already owed; but if he wishes to point to the whole of it, he says 'or it shall be owed' or 'immediately or on a specified day'.
