[IDEM libro trigensimo nono ad Quintum Mucium. ] §18.1.67.prAlienatio cum fit, cum sua causa dominium ad alium transferimus, quae esset futura, si apud nos ea res mansisset, idque toto iure ciuili ita se habet, praeterquam si aliquid nominatim sit constitutum.
[THE SAME, Commentary on Quintus Mucius, Book XXXIX] When an alienation takes place, we transfer ownership to another with its legal condition, such as it would have been if the property had remained with us; and this is so throughout the whole civil law, except if something has been specifically established.
