Actionum libri
Ex libro VIII
Dig. 46,5,11Venuleius libro octavo actionum. In eiusmodi stipulationibus, quae ‘quanti ea res est’ promissionem habent, commodius est certam summam comprehendere, quoniam plerumque difficilis probatio est, quanti cuiusque intersit, et ad exiguam summam deducitur.
Venuleius, Actions, Book VIII. In stipulations which include a promise of as much as the property is worth, it is more convenient to mention a definite sum, for the reason that it is frequently difficult to prove the amount of the interest of each of the persons in question and this is reduced to a very small sum.
