[MARCIANUS libro tertio regularum. ] §41.2.43.prSi quis fundum emerit, cuius particulam sciebat esse alienam, Iulianus ait, si pro diuiso sciat alienam esse, posse eum reliquas partes longa possessione capere: sed si pro indiuiso licet ignoret quis sit locus, aeque eum capere posse, quod sine ullius damno pars, quae putatur esse uendentis, per longam possessionem ad emptorem transit.
[MARCIANUS, in the third book of Rules.] If anyone buys a tract of land, knowing that a small part of it belongs to another, Julian says that, if he knows it belongs to another as a divided part, he can acquire the remaining parts by long possession; but if it is undivided, even though he does not know which specific part it is, he can equally acquire it, because the share which is believed to belong to the seller passes to the buyer through long possession without damage to anyone.
§41.2.43.1Sed et Pomponius scripsit libro quinto uariarum lectionum, si sciat uel putet alienum esse usum fructum, bona fide diutina possessione capere posse.
But Pomponius also wrote in the fifth book of Various Readings that, even if one knows or believes that the usufruct belongs to another, one can acquire [the property] by long possession in good faith.
§41.2.43.2Idem, inquit, et si emero rem, quam sciam pignori obligatam.
The same rule, he says, applies if I buy a thing which I know is pledged.
