[PAULUS libro quinto ad Sabinum. ] §8.4.7.prIn tradendis unis aedibus ab eo, qui binas habet, species seruitutis exprimenda est, ne, si generaliter seruire dictum erit, aut nihil ualeat, quia incertum sit, quae seruitus excepta sit, aut omnis seruitus imponi debeat.
[PAULUS, on Sabinus, book 5] In the transfer of one house by an owner of two, the class of servitude must be specified, lest, if it is stated generally "to serve," it either has no effect because it is uncertain which servitude has been reserved, or all servitudes must be imposed.
§8.4.7.1Interpositis quoque alienis aedibus imponi potest, ueluti ut altius tollere uel non tollere liceat uel etiam si iter debeatur, ut ita conualescat, si mediis aedibus seruitus postea imposita fuerit: sicuti per plurium praedia seruitus imponi etiam diuersis temporibus potest.
A servitude can also be imposed even when another's house is interposed between them—for example, a right to build higher or not to build higher, or even if a right of way is owed—in such a way that it becomes effective if a servitude is subsequently imposed on the intervening house; just as a servitude can be imposed through the estates of several persons even at different times.
quamquam dici potest, si tria praedia continua habeam et extremum tibi tradam, uel tuo uel meis praediis seruitutem adquiri posse: si uero extremo, quod retineam, quia et medium meum sit, seruitutem consistere, sed si rursus aut id, cui adquisita sit seruitus, aut medium alienauero, interpellari eam, donec medio praedio seruitus imponatur.
Although it can be said that, if I have three continuous estates and transfer the furthest one to you, a servitude can be acquired either for your estate or for my estates; but if it is for the furthest estate which I retain, since the middle one is also mine, the servitude is established, but if I subsequently alienate either the one for which the servitude was acquired or the middle one, the servitude is suspended until a servitude is imposed on the middle estate.
