It would be best if opened your own basic bank account prior to bankruptcy, though you are still obliged to provide details of any bank accounts held over the past two years, joint or otherwise.
Most banks are tolerant these days, but Barclays, Lloyds and Cooperative are probably the best, provided you do not owe them money. It would be best if you did not disclose the impending bankruptcy when opening the account or they might ask you to return once the bankruptcy has taken place.
