If a person owns a piece of land, do they own it all the way down to the center of the earth?
Basically, this kind of unusual question tends to be very technical in nature and require an expert to a specific field of study to answer. But in order to answer the above query for the satisfaction of our dear avid readers after basing from my experience and from the knowledge that I’ve gathered, yes, they do own it.
Let us take the case of building owners, or owners of those skyscrapers out there on our business districts. We all know that in order to build such a structure, you must dig a considerable amount of land wherein the foundations of the structure are to be placed or firstly constructed. But I still have to see or hear someone claiming or owning a piece of land located underneath. Not unless he or they can prove it by showing a land title covering or specifically describing the exact measurements or the land coverage that is literally underground so to speak.
These tall buildings do extreme diggings underneath to solidify and strengthen the foundations for the building itself. They even build layers upon layers of basements which they primarily use for parking purposes. Some would even go to the extent of building shopping malls, train stations (subways) beneath as deep as they want it. And through all these activities, no such claims of “trespassing property underneath” are being filed in court. Not unless you arte trying to destroy or obstruct some structures underneath that are long been there and is currently being used by its owners. If you are trying or planning to build a 14-storey basement but a subway line is on its way, finding an alternative would be the best way. It’s actually a “free zone” underneath when it comes to ownership of parcels of land. If you can claim to own it as deep as you can, the better. And it would be best if you can prove it.
There are actually lots of these issues about territorial claims on nations who either claims responsibility or who owns this or who owns that but never have I heard of something or someone that claims owning the land underneath all the way down to the center of the earth. The challenge is too absurd unless you will take the risk of constructing a “coredigger” instead of a “skyscraper”.
