[IDEM libro secundo responsorum. ] §8.3.36.prCum fundo, quem ex duobus retinuit uenditor, aquae ducendae seruitus imposita sit, empto praedio quaesita seruitus distractum denuo praedium sequitur: nec ad rem pertinet, quod stipulatio, qua poenam promitti placuit, ad personam emptoris, si ei forte frui non licuisset, relata est.
[THE SAME, Opinions, Book 2] When a servitude of leading water has been imposed on an estate which the seller retained out of two, the servitude acquired for the purchased estate follows the estate when it is sold again; nor does it matter that the stipulation, by which it was agreed that a penalty should be promised, was referred to the person of the buyer, in case he should happen not to be allowed to enjoy it.
