[PAPINIANUS libro septimo quaestionum. ] §8.4.17.prSi precario uicinus in tuo maceriam duxerit, interdicto 'quod precario habet' agi non poterit, nec maceria posita donatio seruitutis perfecta intellegitur, nec utiliter intendetur ius sibi esse inuito te aedificatum habere, cum aedificium soli condicionem secutum inutilem faciat intentionem.
[PAPINIANUS, book 7 of Questions] If a neighbor has constructed a stone wall on your land by precarium (permissive occupancy), it will not be possible to bring an action under the interdict 'quod precario habet'; nor, by the erection of the stone wall, is a donation of a servitude understood to be completed; nor will it be usefully claimed that he has a right to keep a structure built against your will, since the building, having followed the condition of the soil, makes the claim useless.
ceterum si in suo maceriam precario, qui seruitutem tibi debuit, duxerit, neque libertas usucapietur et interdicto 'quod precario habet' utiliter cum eo agetur. quod si donationis causa permiseris, et interdicto agere non poteris et seruitus donatione tollitur.
But if one who owed a servitude to you has constructed a stone wall on his own land by precarium, freedom [from the servitude] will not be acquired by usucapion, and an action will be usefully brought against him under the interdict 'quod precario habet.' If, however, you permitted this for the sake of a donation, you will not be able to bring an action under the interdict, and the servitude is extinguished by the donation.
