Dominium directum et utile

Dominium directum et utile is a legal Latin term used to refer to the two separate estates in land that a fief was split into under feudal land tenure.^[1] This system is more commonly known as duplex dominium or double domain. This can be contrasted with the modern allodial system, in which ownership is full and not divided into separate estates—a situation known as dominium plenum "full ownership".
