[ULPIANUS libro septimo disputationum. ] §46.4.16.prSi ex pluribus obligatis uni accepto feratur, non ipse solus liberatur, sed et hi, qui secum obligantur: nam cum ex duobus pluribusque eiusdem obligationis participibus uni accepto fertur, ceteri quoque liberantur, non quoniam ipsis accepto latum est, sed quoniam uelut soluisse uidetur is, qui acceptilatione solutus est.
[ULPIAN, Disputations, Book VII] If a release is given to one of several joint debtors, not only is he himself released, but also those who are bound with him; for when a release is given to one of two or more participants in the same obligation, the others also are released, not because a release was given to them, but because he who was released by acceptilalio is regarded as if he had made payment.
§46.4.16.1Si iudicati fideiussor sit datus acceptus eique accepto latum sit, liberabitur et iudicatus.
If a surety for a judgment debt has been given and accepted, and a release is given to him, the judgment debtor also will be released.
