[POMPONIUS libro trigensimo tertio ad Sabinum. ] §8.2.27.prSed si inter te et me communes sunt Titianae aedes et ex his aliquid non iure in alias aedes meas proprias immissum sit, nempe tecum mihi agere licet aut rem perdere.
[POMPOMIUS, in the thirty-third book on Sabinus.] But if the Titian house is common between you and me, and something from it has been unlawfully projected into another house of mine which is my sole property, surely I am permitted to bring an action against you, or else lose the thing.
idem fiet, si ex tuis propriis aedibus in communes meas et tuas aedes quid similiter esset proiectum: mihi enim soli tecum est actio.
The same will happen if something has likewise been projected from your own house into the house common to me and you; for I alone have an action against you.
§8.2.27.1Si in area communi aedificare uelis, socius prohibendi ius habet, quamuis tu aedificandi ius habeas a uicino concessum, quia inuito socio in iure communi non habeas ius aedificandi.
If you should wish to build on a common plot of land, your co-owner has the right of prohibition, although you may have a right of building granted by a neighbor, because against the will of your co-owner you do not have the right of building on common property.
