A more thorough explanation:

de coelo usque ad inferos

De coelo usque ad inferos is a Latin phrase that means "from heaven to the center of the earth." This phrase is often used in the context of real estate law to describe the extent of a property owner's ownership interest in the property.

For example, if you own a piece of land, your ownership interest extends from the sky above the property to the center of the earth below it. This means that you have the right to use and control everything within that space, including any buildings, trees, or minerals that may be present.

Similarly, if you own a house, your ownership interest extends from the roof above the property to the foundation below it. This means that you have the right to use and control everything within that space, including the walls, floors, and any fixtures or appliances that may be present.
