[PAULUS libro decimo ad Sabinum. ] §7.1.24.prSi quis donaturus usufructuario spoponderit servo in quem usum fructum habet stipulanti, ipsi usufructuario obligabitur, quia ut ei seruus talis stipulari possit, usitatum est.
[PAULUS in the tenth book on Sabinus.] If anyone, intending to make a donation to a usufructuary, makes a promise to the slave in whom the usufructuary has the usufruct and who is stipulating, he will be bound to the usufructuary himself, because it is customary that such a slave can stipulate for him.
