Spain's National Court has asked for a copy of the contract before deciding whether to proceed with a complaint alleging misappropriation of funds by the club in the Neymar signing.
"We will be happy to deliver all documentation requested of us," Rosell told a news conference.
"The National Court has already asked us for the information about Neymar's contract."
Judge Pablo Ruz on Wednesday requested copies of the Neymar contract and the club's related financial records before deciding whether to proceed with the complaint against Rosell, as club president.
Barcelona has said it paid a total 57 million euros to sign Neymar from Brazilian club Santos, but it declined to give full details, citing a need for confidentiality.
A Barcelona club member accuses Rosell of misappropriation of funds because the members do not know the "real destination" of some 40 million euros supposedly paid to Neymar family business N&N.
