If a person has only usus and fructus rights, what do they possess?

The person who has only usus and fructus rights possesses what is known as usufruct. In legal terms, usufruct is a right that allows an individual to use and enjoy the benefits (fructus) of property owned by another party, while the ownership (naked ownership) remains with the original owner. Essentially, this means that the individual can utilize the property and derive profit from it, such as collecting rent or harvesting crops, but cannot sell or destroy the property itself.

The concept of usus refers to the right to use the property, while fructus pertains to the right to enjoy the fruits or benefits produced by that property. Together, these rights define the usufruct, highlighting the distinction between ownership of the property and the rights to use and benefit from it.

Considering the other options, appurtenances refer to rights or services that come with the property, corporeal interests pertain to actual physical interests in property, and laches is a legal doctrine concerning the failure to assert a right in a timely manner. None of these accurately capture the nature of merely having usus and fructus rights, affirming that usufruct is indeed the correct concept related to the rights described in the question.
