[ULPIANUS libro duodecimo ad edictum. ] §41.7.1.prSi res pro derelicto habita sit, statim nostra esse desinit et occupantis statim fit, quia isdem modis res desinunt esse nostrae, quibus adquiruntur.
[ULPIAN, from his twelfth book on the Edict.] If a thing is regarded as abandoned, it immediately ceases to be ours and immediately becomes the property of the occupier, because things cease to be ours by the same means by which they are acquired.
