[IDEM libro quarto decimo digestorum. ] §46.1.13.prSi mandatu meo Titio decem credideris et mecum mandati egeris, non liberabitur Titius: sed ego tibi non aliter condemnari debebo, quam si actiones, quas aduersus Titium habes, mihi praestiteris.
[THE SAME in the fourteenth book of the digests.] If on my mandate you have lent Titius ten, and you bring an action of mandate against me, Titius will not be released; but I ought not to be condemned to you otherwise than if you surrender to me the actions which you have against Titius.
item si cum Titio egeris, ego non liberabor, sed in id dumtaxat tibi obligatus ero, quod a Titio seruare non potueris.
Likewise, if you bring an action against Titius, I shall not be released, but I shall be obligated to you only for that which you could not recover from Titius.
