Why do courts usually hear real-property cases where the land is located?

In the context of conflict of laws, courts typically exercise jurisdiction over real-property cases where the land is located because these matters often involve judgments in rem (Latin for "with respect to the thing").1

Unlike in personam actions, which concern personal legal rights and may seek money damages, in rem actions seek a judgment that produces direct effects on a specific legal relationship or property interest. Examples include actions to quiet title, foreclose a mortgage, or remove an encumbrance on land. Because these cases involve proprietary legal rights tied to a specific site, the court at the location of the property is uniquely positioned to exercise authority over the asset. This principle is closely related to the concept of lex loci rei sitae, which refers to the law of the place where the property is situated.12
