So you're living in a fancy house. You've got plenty of rooms, a luxurious kitchen with a well-stocked pantry, a huge garden and other neat amenities like a swimming pool and home theater. There's just one little problem...this house doesn't legally belong to you.
Some houses remain unoccupied for long periods of time. Maybe the owners live in another state or even another country, maybe it's on the market for rent but hasn't found any takers, or perhaps the owner is constantly taking long-term trips. Either way, a drifter, a swindler, or someone just looking for a place to stay may decide to take up residence in said empty house.
Truth in Television, but one should do this at their own risk. In the USA and many other countries, this is considered squatting and may overlap with other criminal charges like trespassing or burglary. You also risk injurious or lethal consequences, especially in areas with castle doctrine. On the other hand, in some countries, someone who has lived in an abandoned house long enough with no demands to leave can claim legal ownership.
