dominium

Dominium is a legal term denoting ownership of a thing, representing the right to use, enjoy, and dispose of it to the extent allowed by law. It constitutes the most complete title in many civil-law systems, distinguishing ownership from mere possession or limited real rights.

Originating in Roman law, dominium described the highest form of ownership. The owner possessed iura in re: ius utendi (use), ius fruendi (fruits or income), and ius abutendi (disposal or consumption). Although the exact scope changed over time, dominium signified a bundle of sovereign powers over the object.

In feudal and later civil-law practice, dominium was sometimes analyzed as a twofold structure: dominium directum (the direct or ultimate title held by a lord or holder of the ultimate right) and dominium utile (the user’s or beneficiary’s right to use and profit from the property).

In modern property law, dominium is usually treated as the ownership title and its essential faculties, while possession, usufruct, servitudes, and liens are separate rights or encumbrances that can exist alongside or impede dominium. Transfers, leases, and mortgages typically affect dominium or its fruits.

Today, the term is most often encountered in historical or civil-law contexts; many jurisdictions describe ownership simply as property or title, reserving dominium as the formal Latin-language expression for ownership rights in legal discussion or in specific codes.
