Bradford are back in administration after the club's creditors applied for the order.
Bradford's future remains uncertain
Bradford spent a period in administration in 2002, before agreeing a Creditors' Voluntary Agreement (CVA), which saw them stay in the league.
But the Bantams are now in the hands of the accountant firm Kroll.
The club's finances have been the cause of a feud between the Rhodes family and former chairman Gordon Gibb, both major shareholders at Valley Parade.
The Rhodes family and Gibb helped rescue the club early in 2003.
Director David Rhodes told Bradford's website: "Since we [the Rhodes family] are not willing to continue to gift any further funds to the club, and because the club have now defaulted on its CVA payments, the supervisors of the CVA have had no other option but to seek an administration order."
The feud took a twist before last Saturday's game against Crewe when Gibb, who resigned as chairman last month, addressed the crowd from the side of the pitch.
Gibb revealed the reason he resigned was because he "felt let down by the
family he worked with" and no longer wanted to work with them.
