A more thorough explanation:

LOCUS REI SITAE

Locus rei sitae is a Latin term that means "place where a thing is situated." In civil law, it refers to the rule that the proper forum for a case involving real estate is the place where the land is located.

For example, if a dispute arises between two parties over the ownership of a piece of land, the case should be heard in the court that has jurisdiction over the area where the land is located. Similarly, if a person wants to file a lawsuit to enforce a real estate contract, they must do so in the court that has jurisdiction over the place where the property is situated.

Another example would be if a person wants to file a lawsuit against their neighbor for building a fence that encroaches on their property. The case should be heard in the court that has jurisdiction over the area where the land is located.

Locus rei sitae is a legal principle that ensures that cases involving real estate are heard in the proper forum. This principle is important because it ensures that the court that has the most knowledge and expertise about the area where the land is located will hear the case. This helps to ensure that the case is decided fairly and justly.
