[IDEM libro quadragensimo octauo ad edictum. ] §46.5.5.prIn omnibus praetoriis stipulationibus hoc seruandum est, ut, si procurator meus stipuletur, mihi causa cognita ex ea stipulatione actio competat.
[THE SAME, on the Edict, Book XLVIII] In all praetorian stipulations this must be observed: that if my procurator enters into a stipulation, an action from that stipulation shall, after an inquiry into the case, belong to me.
idem est et cum institor in ea causa esse coepit, ut interposita persona eius dominus mercis rem amissurus sit, ueluti bonis eius uenditis: succurrere enim domino praetor debet.
The same holds also when a manager begins to be in such a situation that, through the intervention of his person, the owner of the goods is about to lose the property, for instance, if the manager's property has been sold; for the praetor ought to succour the owner.
