[ULPIANUS libro quarto ad edictum. ] §2.14.16.prSi cum emptore hereditatis pactum sit factum et uenditor hereditatis petat, doli exceptio nocet.
[ULPIANUS, On the Edict, book 4] If an agreement is made with the buyer of an inheritance and the seller of the inheritance sues, the plea of fraud is prejudicial.
nam ex quo rescriptum est a diuo Pio utiles actiones emptori hereditatis dandas, merito aduersus uenditorem hereditatis exceptione doli debitor hereditarius uti potest.
For since the deified Pius issued a rescript that beneficial actions must be granted to the buyer of an inheritance, the hereditary debtor can deservedly use the plea of fraud against the seller of the inheritance.
§2.14.16.1Sed et si inter dominum rei uenditae et emptorem conuenisset, ut homo qui emptus erat redderetur, ei qui pro domino rem uendidit petenti pretium doli exceptio nocebit.
But also, if it has been agreed between the owner of the sold property and the buyer that the slave who had been bought should be returned, the plea of fraud will prejudice the person who sold the property on behalf of the owner when he sues for the price.
