Ad coelum

Ad coelum is a Latin phrase that means "to the sky." It's used in legal contexts to refer to the idea that a property owner controls everything above and beneath their property.

Think of it like this: imagine you have a big piece of land, and you want to build a really tall tower on it. Ad coelum means that you have the right to build that tower as high as you want, because everything above your land belongs to you.

It also means that everything below your land belongs to you. So if you were to dig a tunnel underneath your land, anything you find there (like oil or minerals) would be yours to keep.

Ad coelum is an important concept in property law, because it helps to establish clear boundaries between different pieces of land. It also gives property owners the freedom to use their land in creative ways, like building really tall buildings or digging deep underground tunnels.
