[MODESTINUS libro quinto regularum. ] §41.3.18.prQuamuis aduersus fiscum usucapio non procedat, tamen ex bonis uacantibus, nondum tamen nuntiatis, emptor praedii ex isdem bonis exstiterit, recte diutina possessione capiet: idque constitutum est.
[MODESTINUS, Rules, book 5] Although usucapion does not run against the imperial treasury, nevertheless, if a buyer of land from ownerless property should emerge from that same property before it has been reported, he will rightfully acquire it by long-term possession; and this has been established by decree.
