Dominum directum (Feudal): the right of the lord (i.e., the right to direct) in the disposition of an asset (typically land).
Dominum utile (Feudal): the right of use and utility of an asset, and to keep the benefits (such as the right to live on the land, and to keep the profits from agriculture).
The terms derive from Latin dominum (domain, dominion), directum (direction, in the sense of leadership), and utile (use, utility).
An asset is defined to mean itself and those things that naturally go with it. For land, that would include buildings, trees, underground resources, etc. It would not include "movable" property, such as wagons or livestock.
The definition was constructed from the sources. [1] [2] [3] [4] [5]
The "lord" holding dominum directum may be anyone with sovereign power over the asset, such as a monarch or other nobility, or an established Christian Church.
