[GAIUS libro septimo ad edictum prouinciale. ] §8.2.6.prHaec autem iura similiter ut rusticorum quoque praediorum certo tempore non utendo pereunt: nisi quod haec dissimilitudo est, quod non omnimodo pereunt non utendo, sed ita, si uicinus simul libertatem usucapiat.
[GAIUS in the seventh book on the Provincial Edict.] However, these rights, similarly to those of rustic estates, perish by non-use for a certain period of time: except that there is this difference, that they do not perish by non-use in every case, but only if the neighbor at the same time acquires freedom by usucapion.
ueluti si aedes tuae aedibus meis seruiant, ne altius tollantur, ne luminibus mearum aedium officiatur, et ego per statutum tempus fenestras meas praefixas habuero uel obstruxero, ita demum ius meum amitto, si tu per hoc tempus aedes tuas altius sublatas habueris: alioquin si nihil noui feceris, retineo seruitutem.
For example, if your house is subject to a servitude to my house, that it is not to be raised higher, or that the light of my house is not to be obstructed, and I, during the statutory period, have kept my windows blocked or obstructed, I lose my right only if you, during this period, have kept your house raised higher: otherwise, if you have done nothing new, I retain the servitude.
item si tigni immissi aedes tuae seruitutem debent et ego exemero tignum, ita demum amitto ius meum, si tu foramen, unde exemptum est tignum, obturaueris et per constitutum tempus ita habueris: alioquin si nihil noui feceris, integrum ius suum permanet.
Likewise, if your house owes a servitude of inserting a beam, and I have removed the beam, I lose my right only if you have blocked the hole from which the beam was removed, and have kept it so for the established period: otherwise, if you have done nothing new, the right remains unimpaired.
