[POMPONIUS libro quinto decimo ad Sabinum. ] §46.3.16.prSub condicione debitori si acceptum feratur, postea condicione existente intellegitur iam olim liberatus.
[POMPONIUS libro quinto decimo ad Sabinum.] If a release is granted to a debtor under a condition, when the condition subsequently occurs, he is understood to have been released already from the beginning.
et hoc etiam si solutio re fiat, accidere Aristo dicebat.
And Aristo used to say that this also happens even if payment is made in reality.
scripsit enim, si quis, qui sub condicione pecuniam promisit, dedit eam ea condicione, ut, si condicio exstitisset, in solutum cederet, existente condicione liberari eum nec obstare, quod ante eius pecunia facta est.
For he wrote that if anyone who promised money under a condition gave it on the condition that, if the condition should occur, it should go towards payment, then when the condition occurs, he is released, and it is no obstacle that the money had previously become the property of the creditor.
