[MARCIANUS libro tertio regularum. ] §46.3.46.prSi quis aliam rem pro alia uolenti soluerit et euicta fuerit res, manet pristina obligatio.
[MARCIANUS in the third book of Rules.] If anyone pays to a willing person one thing instead of another, and the thing is evicted, the original obligation remains.
etsi pro parte fuerit euicta, tamen pro solido obligatio durat: nam non accepisset re integra creditor, nisi pro solido eius fieret.
Even if it is evicted in part, the obligation nevertheless continues for the whole; for the creditor, before performance, would not have accepted it unless it became his in its entirety.
§46.3.46.1Sed et si duos fundos uerbi gratia pro debito dederit, euicto altero fundo remanet integra obligatio.
But also, if he gives, for example, two estates for a debt, and one of the estates is evicted, the obligation remains intact.
tunc ergo res pro re soluta liberationem praestat, cum pro solido facta est suscipientis.
Therefore, a thing paid instead of another only brings release when it has become the property of the recipient in its entirety.
§46.3.46.2Sed et si quis per dolum pluris aestimatum fundum in solutum dederit, non liberatur, nisi id quod deest repleatur.
But also, if any one through fraud gives in lieu of payment an estate valued at more than its worth, he is not released unless that which is lacking is made up.
