1.An occupier of land has rights superior to those of a finder over chattels in or attached to that land and an occupier of a building has similar rights in respect of chattels attached to that building, whether in either case the occupier is aware of the presence of the chattel.
2.An occupier of a building has rights superior to those of a finder over chattels upon or in, but not attached to, that building if, but only if, before the chattel is found, he has manifested an intention to exercise control over the building and the things which may be upon it or in it.
3.An occupier who manifests an intention to exercise control over a building and the things which may be upon or in it so as to acquire rights superior to those of a finder is under an obligation to take such measures as in all the circumstances are reasonable to ensure that lost chattels are found and, upon their being found, whether by him or by a third party, to acquaint the true owner of the finding and to care for the chattels meanwhile. The manifestation of intention may be express or implied from the circumstances including, in particular, the circumstance that the occupier manifestly accepts or is obliged by law to accept liability for chattels lost upon his "premises," e.g. an innkeeper or carrier's liability.
4.An "occupier" of a chattel, e.g. a ship, motorcar, caravan or aircraft, is to be treated as if he were the occupier of a building for the purposes of the foregoing rules.
