What refers to private property taken by the state for public use?

Expropriation is the legal process by which a governmental entity takes private property for public use, often with compensation provided to the property owner. This process is often based on the principle of eminent domain, allowing governments to claim private land or property to facilitate projects that serve the public interest, such as infrastructure development (roads, schools, parks).

In regard to the other terms, usufructuary pertains to the right to use and enjoy the benefits of property that belongs to another, which is not related to the government's taking of property for public use. Negative servitude refers to a servitude that restricts the property owner's use of their property in a way that benefits another, which again does not involve the state taking property. Reconduction refers to the renewal of a lease and does not involve property expropriation. Therefore, expropriation is the most accurate term describing the taking of private property by the state for public objectives.
