Facebook founder Mark Zuckerberg has said that an alleged contract and e-mails that a New York man claims entitle him to a 50% stake in the social networking site are “forgeries”.
Paul Ceglia says that Mr Zuckerberg signed a contract in 2003 which gave Mr Ceglia half-ownership of Facebook.
In a court filing, Facebook and Mr Zuckerberg demand that Mr Ceglia turn over the alleged contract and e-mails.
Lawyers representing Mr Ceglia disputed Facebook’s claims.
“Those so-called expert opinions have been provided without examining the actual contract which is at issue in the case,” said Dennis C Vacco, who is one of Mr Ceglia’s attorneys.
