Citronella- I went bankrupt in 2004 so can only go on my own experience not sure if things have changed since then?
Re costs: yes you pay to go bankrupt ( the irony) it was at least £200 when I went through it- no idea of costs now though. We did struggle to find this money.
Once you file the papers at court you will get a hearing date, from then on you cannot pay any of your creditors at all- you can't be seen to favour one over the other. Once you have the hearing date though you are able to inform them of this and I found they stopped hounding quite so much.
I sought advice from our local ' advice point' like a local CAB- I was asked by the judge if I had gained advice, so would suggest you do too to explore all of your options. When I went for advice I fully expected to be told to enter into an IVA, but due to the level of debt Bankruptcy was recommended straight away.
I was not required to make any payment back after the bankruptcy as I had very little income of my own and wouldn't have been able to afford to, I know others have had to though.
The car was in my name and the receiver set a date for it to be removed from me, however, I was able to make an extremely low offer for it, so purchased it back if that makes sense?
I had to list items of value (didn't really have any) they will not take essential items from you, or anything belonging to your children. I had visions of the TV being taken etc, but it was just the car.
With the bank account, I walked out of the court and straight to the CO-OP who opened me a basic 'cashminder' account- oh that is another thing to be mindful of, once you go into court your bank accounts will be frozen, don't open the new one until after the hearing.
Moneysaving expert has some really good information on the process.
