Two homeless Hungarian brothers who have been living in a cave and selling discarded junk for a living are in line to inherit almost $7 billion from a long-lost German grandmother’s fortune, Britain’s Telegraph reports.

Their sister, who lives in America, will also share in the inheritance.

The fortune comes from the estate of a maternal grandmother who died recently in Baden-Wurttemberg, Germany, the Telegraph says.

“We knew our mother came from a wealthy family but she was a difficult person and severed ties with them, and then later abandoned us and we lost touch with her and our father until she eventually died,” 43-year-old Geza Peladi told Hungary’s ATV television.

The name of the deceased is being kept secret to prevent scam artists from coming forward, the paper says.

Geza and his brother, Zsolt, who live in a cave outside Budapest, got the news from a charity worker who was contacted by lawyers for the estate. Under German law, direct descendants are automatically entitled to a share of any estate.

“If this all works out it will certainly make up for the life we have had until now — all we really had was each other — no women would look at us living in a cave,” said Geza. “But with money, maybe we can find a partner and finally have a normal life.”

The brothers are currently getting copies of their mother’s death certificate and proof of their identity before going to Germany to claim the fortune.

Unbelievable, huh?
