[PAULUS libro tertio ad Sabinum. ] §33.2.1.prNec usus nec usus fructus itineris actus uiae aquaeductus legari potest, quia seruitus seruitutis esse non potest: nec erit utile ex senatus consulto, quo cauetur, ut omnium quae in bonis sint usus fructus legari possit, quia id neque ex bonis neque extra bona sit.
[PAULUS, On Sabinus, book III.] Neither the use nor the usufruct of a right of way, passage, road, or aqueduct can be bequeathed, because there cannot be a servitude of a servitude; nor will it be valid under the senatusconsultum by which it is provided that the usufruct of all things which are in one's patrimony can be bequeathed, because this is neither in patrimony nor outside of patrimony.
sed incerti actio erit cum herede, ut legatario, quamdiu uixerit, eundi agendi ducendi facultatem praestet aut ea seruitus constituatur sub hac cautione, ut, si decesserit legatarius uel capite deminutus ex magna causa fuerit, restituatur.
But there will be an action for an uncertain amount against the heir, so that he may provide the legatee, as long as he lives, with the facility of walking, driving, or drawing water, or that the servitude be established under this security, that if the legatee dies or undergoes a change of status for a major cause, it shall be restored.
