[ULPIANUS libro quadragensimo octauo ad Sabinum. ] §45.3.11.prSed si sibi aut Primo aut Secundo dominis suis stipulatus sit, et hic tantundem erit probandum, quod Iulianus, inutilem esse stipulationem.
[ULPIAN, from the forty-eighth book on Sabinus.] But if a slave should stipulate for himself, or for Primus, or for Secundus, his masters, here too the same must be approved as Julian held, namely, that the stipulation is void.
sed utrum adiectio inutilis est aut tota stipulatio utilis non est? puto adiectionem solam esse inutilem: eo enim quod ait 'mihi' omnibus adquisiit ex personae? et puto uel solui eis posse, quemadmodum cum ego mihi aut Titio stipuler.
But is the addition void, or is the entire stipulation not valid? I think that the addition alone is void; for by the fact that he said "for me," he acquired for all of them from his own person. And I think that payment can even be made to them, just as when I stipulate for myself or for Titius.
cur ergo cum Primo aut Secundo dominis stipulatio non constitit nec solutio est? illa ratio est, quia non inuenimus, in cuius persona stipulatio constitit, in cuius solutio.
Why then, when he stipulates for "Primus or Secundus, his masters," does the stipulation not stand, nor is there any valid payment? The reason is that we do not find in whose person the stipulation stood, and in whose person the payment.
