[IULIANUS libro decimo digestorum. ] §12.6.20.prSi reus et fideiussor soluerint pariter, in hac causa non differunt a duobus reis promittendi: quare omnia, quae de his dicta sunt, et ad hos transferre licebit.
[JULIAN, Digest, Book 10.] If the principal debtor and the surety have paid equally, in this case they do not differ from two co-debtors; therefore, it will be permissible to transfer everything that has been said of the latter to the former as well.
