A Non Domino
From FMOTL Wiki
"A non domino" is a latin adjective phrase implying that something is "not from the master". It has a specific usage in land aquisitions, where a deed to land may be granted by someone who is "not the owner". The granter of such a deed is sometimes referred to as the "a non domino"; the deed can be referred to as an "a non domino" deed.
In Scotland, the a non domino facility is described as a legitimate means whereby a right to land may be created by a process of positive prescription. Usually the rights created are auxilliary to rights which already exist closeby or on the same land. For example, it is common for an a non domino deed to be created favouring a landowner the right to use a road which bounds his land. It is not uncommon for land, having no identifiable owner to be claimed on a prescriptive a non domino deed.
