[GAIUS libro uicensimo septimo ad edictum prouinciale. ] §46.6.6.prSeruum pupilli stipulari ita necesse est, si pupillus abest aut fari non potest: nam si praesens sit et fari potest, etiamsi eius aetatis erit, ut non intellegat quid agat, tamen propter utilitatem receptum est recte eum stipulari.
[GAIUS, On the Provincial Edict, Book XXVII] It is necessary for a ward's slave to stipulate only if the ward is absent or cannot speak; for if he is present and can speak, even if he is of such an age that he does not understand what he is doing, it has nevertheless been accepted for the sake of utility that he himself can rightly stipulate.
