In 1984 financial matters came to a head and the club went into administration , to be reformed as Charlton Athletic . ( 1984 ) Ltd. although the club 's finances were still far from secure . They were forced to leave the Valley just after the start of the 1985 – 86 season , after its safety was criticised by Football League officials in the wake of the Bradford City stadium fire . The club began to groundshare with Crystal Palace at Selhurst Park and this arrangement looked to be for the long-term , as Charlton did not have enough funds to revamp the Valley to meet safety requirements
