A more thorough explanation:

Res immobiles are things that cannot be moved. They are also known as chattels real in civil law. Examples of res immobiles include land, buildings, and other permanent structures.

For instance, a house is a res immobile because it is a permanent structure that cannot be moved. Similarly, a piece of land is also a res immobile because it cannot be moved from one place to another.

Understanding the concept of res immobiles is important in real estate and property law because it helps to differentiate between movable and immovable property. This distinction is crucial in determining ownership, transfer of property, and other legal matters.
