On paper, the concept of land ownership sounds very simple- you pay money and in return you’re given unfettered access to a predetermined amount of land. But how much of that land do you actually own? Do you own the sky above it? How about the land below it? What about all the animals that may live there; do you own those too? All of these questions and more define what exactly it means to “own” a piece of land. Surprisingly, many of the answers aren’t well defined from a legal standpoint as you’ll soon see.
