[ULPIANUS libro trigesimo secundo ad Sabinum. ] §24.1.19.prSi uxor filio donauerit seruum, qui in patris mariti sit potestate, deinde is seruus ancillam acceperit, dominium mulieri quaeretur: nec interesse Iulianus ait, ex cuius pecunia haec ancilla empta sit, quia nec ex re sua quicquam adquiri potest per eum qui donatur ei cui donatur: hoc enim bonae fidei possessoribus concessum est, uirum autem scientem alienum possidere.
[ULPIANUS libro trigesimo secundo ad Sabinum.] If a wife has donated a slave, who is under the power of his father the husband, to the son, and then this slave has received a female slave, the ownership is acquired for the woman; and Julian says it does not matter from whose money this female slave was bought, because nothing can be acquired from one's own property through him who is donated to him to whom he is donated; for this is conceded to possessors in good faith, but the husband possesses knowing that the slave belongs to another.
§24.1.19.1Idem quaerit, si ex re mariti ea ancilla comparata fuerit, an aduersus agentem mulierem de dote maritus pretium possit per exceptionem retinere.
The same author asks, if that female slave was purchased from the husband's property, whether the husband can retain the price by means of an exception against the wife who is suing for her dowry.
et dicendum est posse maritum et exceptionem habere, si dos ab eo petetur, secundum Marcelli sententiam et, si soluerit, secundum Iulianum condicere posse.
And it must be said that, according to the opinion of Marcellus, the husband can indeed have an exception if the dowry is claimed from him, and, according to Julian, if he has paid it, he can bring an action for recovery.
