[CELSUS libro octauo digestorum. ] §18.1.59.prCum uenderes fundum, non dixisti 'ita ut optimus maximusque': uerum est, quod Quinto Mucio placebat, non liberum, sed qualis esset, fundum praestari oportere.
[CELSUS, Digest, Book VIII] When you sold the land, you did not say "in the state of best and greatest". It is true, as Quintus Mucius was pleased to hold, that the land ought to be delivered not as free from all encumbrances, but in whatever state it actually was.
idem et in urbanis praediis dicendum est.
The same must also be said in the case of urban estates.
