Property Ownership Is Complicated Figuring out who owns property is surprisingly complicated. For one thing, real property itself is complicated – it’s not just an invisible square on the ground, but might include water rights, mineral rights, air rights, easements that allow other people to access the property, liens for taxes, mortgages, loans, or other improvements, and so on. The boundaries of your property might move in an earthquake, or with rising sea levels or erosion.
