Abstract
One of the methods of transferring land rights between private legal subjects and public legal subjects is land rights exchange. Land rights exchange occurs when an owner of a land right exchanges their right with another land right owned by another owner. Land ownership between a private legal subject and a public legal subject is valid if the applicable law is fulfilled. This research aims to investigate the validity terms in land right exchange between private legal subjects and public legal subjects. This research employs a legal normative method, with the approach methods applied being the statute approach and the case approach. As a result of this research, the land right exchange between private legal subjects and public legal subjects is valid as long as it fulfills the material and formal requirements stipulated in Law 5/1960, Government Regulation 24/1997, and other relevant regulations. At the very least, a land rights exchange is valid if the legal subject can exchange the land rights and the exchange process is conducted by the applicable law.
