Ad legem Iuliam et Papiam libri
Ex libro IX
Dig. 50,16,150Idem libro nono ad legem Iuliam et Papiam. Si ita a te stipulatus fuero: ‘quanto minus a Titio consecutus fuero, tantum dare spondes?’, non solet dubitari, quin, si nihil a Titio fuero consecutus, totum debeas quod Titius debuerit.
The Same, On the Lex Julia et Papia, Book IX. If I stipulate with you as follows: “Do you promise to pay me whatever I may fail to collect from Titius?” there is no doubt that if I should not collect anything from Titius you will be indebted to me for all that he owed me.
