[ULPIANUS libro septuagensimo nono ad edictum. ] §46.6.2.prSi pupillus absens sit uel fari non possit, seruus eius stipulabitur: si seruum non habeat, emendus ei seruus est: sed si non sit unde ematur aut non sit expedita emptio, profecto dicemus seruum publicum apud praetorem stipulari debere:
[ULPIANUS, On the Edict, Book LXXIX] If a pupil is absent or cannot speak, his slave shall stipulate; if he has no slave, a slave must be bought for him; but if there are no funds from which one may be bought, or if the purchase is not convenient, we should certainly say that a public slave ought to stipulate before the praetor.
