[ULPIANUS libro primo ad edictum aedilium curulium. ] §21.1.27.prDebet autem recipere pecuniam, quam dedit pro eo homine, uel si quid accessionis nomine.
[ULPIANUS libro primo ad edictum aedilium curulium.] Moreover, he ought to recover the money which he paid for that slave, or any sum paid under the head of an accession.
dari autem non id solum accipiemus, quod numeratur uenditori, ut puta pretium et usuras eius, sed et si quid emptionis causa erogatum est.
And we shall interpret "to be paid" as referring not only to what is counted out to the seller, such as the price and its interest, but also to whatever has been expended for the sake of the purchase.
hoc autem ita demum deducitur, si ex uoluntate uenditoris datur: ceterum si quid sua sponte datum esse proponatur, non imputabitur: neque enim debet quod quis suo arbitrio dedit a uenditore exigere.
This, however, is brought into account only if it is paid in accordance with the will of the seller; on the other hand, if it is proposed that something was paid of his own accord, it will not be charged; for no one ought to demand from the seller what he paid of his own judgment.
quid ergo, si forte uectigalis nomine datum est, quod emptorem forte sequeretur? dicemus hoc quoque restituendum: indemnis enim emptor debet discedere.
What then, if it happened to be paid under the head of a tax, which would otherwise have fallen upon the buyer? We shall say that this too must be restored; for the buyer ought to depart free from loss.
