Hatton formally announced on Monday the end of his working relationship with Warren and challenged his promoter to put on display the elusive documents, which Warren claimed he held but Hatton denied existed.
Warren showed a contract and a letter which appear to clearly show that Hatton, who signed the contract on 10 December, 2004, still has three fights left under Warren.
Also on display at a hotel in London's Park Lane was Warren's proof that Hatton has made £6.3m so far in his career, which is also something that the boxer has denied.
The next stage in the Hatton-Warren feud will be in court before Hatton's proposed fight for a rival promoter on 26 November. Warren has applied for an injunction against that fight taking place. A decision in court for Warren is unlikely to be the end of the affair. Hatton's lawyer has spoken of simply paying damages if they lose, but the promoter insisted: "How can you put a price on fights that I've not yet made? That is preposterous.''
There is no time limit attached to the three remaining fights, which would preclude Hatton from simply not fighting for a year or two before finding himself a free man. Hatton now faces the prospect of losing in court and then never fighting again. Presumably, if that happened, Warren would seek damages.
