Occupatio (Scots law)
Occupatio or Occupation is a method of original acquisition of property in Scots law. It derives from the Roman law concept of the same name. Occupatio allows a occupier of an object (rem: 'a thing') with the intention to own the property to become the owner. As most property in Scotland is owned, and with the "caduciary", or "escheat", right that all ownerless property falls to the Crown, its application is uncommon. Nevertheless, it remains a valid method of requiring ownership in Scots law. Roman law. In Roman law, "Occupatio" was an original method of acquiring ownership  of un-owned property ("res nullius") by occupying with intent to own. Nicholas argues this is the "archetype" of all other Roman law methods of original acquisition. According to the Roman jurist Gaius, any previously unowned thing becomes the just property of the first occupant able to "capture" it: Abandoned goods ("res derelictae") was also "res nullius" and subject to acquirement through "occupatio". Application in Scots law. Original acquisition. In original acquisition, the new Owner is first person to take ownership (ie: acquire) of the ownerless thing (res nullius). The law of original acquisition is strictly applied, and an original  acquisition will only occur in a few specific situations, including acquisition by occupatio. The Crown's role as "ultimus haeres" and recipient of any "bona vacantia" (ie: abandoned) property in Scotland means that acquisition of previously unowned property is uncommon but occupatio remains a valid method to acquire ownership. Ownerless things capable of occupatio acquisition. The following things (res nullius) were considered capable of acquisition by occupatio: Occupatio of Shells, pearls, gems, pebbles or precious stones on the sea-shore. The above items were considered by the institutional writer Erskine to be "res nullius" capable of acquisition by occupatio. In  Scotland, the foreshore is owned by the Crown as part of the inter-regalia. Occupatio of wild animals. Acquisition of the wild animal with the intent to own it vests the "occupier" or "holder" a real right of ownership"." This is said to apply irrespective of whether the property has been taken from another person's land. This is because the owner of the land have no real right of ownership in the unowned thing itself, only a right "to take". Therefore, wild animals ("ferae naturae)" which are not tame or domesticated animals, or salmon fish, are capable of being  acquired by occupatio to give the "taker" a real right of ownership. If the wild animal frees itself from the occupier, the animal is considered wild or "ferae naturae" again. Animals which return to their owner, such as bees or pigeons, are not considered "ferae naturae." However in practice, the poacher will lose ownership of the wild animal as a matter of forfeiture for committing a criminal offence. This is because poaching and other forms of theft are a criminal offence for the taking of wild animals without an owner's consent, such as Part III of the Deer Scotland  Act 1996. Specific criminal offences in relation to types of Scottish wild animals are found in the Wildlife and Natural Environment (Scotland) Act 2011 and the Wildlife and Countryside Act 1981. Additionally, the criminal courts of Scotland also have a general power under the Proceeds of Crime Act 2002 to order the forfeiture and sale of the captured wild animal. Wild Salmon fish belong to the Crown and therefore form part of the inter regalia, so are excluded from acquisition by "occupatio." Similarly, escaped farmed fish are not considered "ferae naturae" so are not capable of "occupatio" acquisition. Occupatio (Scots
