before the break worth $2.5 million. It turned out that a man moved in on his own and never paid for a thing. He's not the only one. Here's abc's clayton sandell tonight. Reporter: It's a $2.5 million florida mansion free for the taking. At least that's the theory. Last july, after bank of america foreclosed on this five-bedroom waterside estate forcing the owners out, andre barbosa, a 23-year-old brazilian national, moved in. Nobody is happy. We all spent a lot of money to live on this street. Reporter: Police were called but barbosa is claiming adverse possession, allowing anyone to claim an empty property by occupying it seven years. It was intended for properties that had been abandoned or neglected. Reporter: And it's not just in florida, adverse possession is legal in all 50 states. In texas, kenneth robinson lived in here for seven months. He was eventually kicked out. Reporter: She used the arcane law to take over three homes? Georgia. She was later arrested. Property owners can get drawn-out expensive legal migraines. Their stories usually have the same stories. Documents he may file, will all probably end up, leading to the same conclusion, and that is, that he gets kicked out. Reporter: Bank of america is now trying to do just that. When it comes to barbosa's free home, this squatter is far from home free. Clayton sandell, abc news, denver.
