My friend went bankrupt recenty, best thing she did.
If you are moving into rented the best thing you can do is put your house on the market now, or hand the keys back to the mortgage company if there is no equity.
Regarding your car - if you need it for work it should be fine to keep it too, especially if worth no more than £3k.
Bank accounts - set up a building society account with a passbook or cash card now ready for bankruptcy, or try and arrange for your wages to be paid by cash or cheque to someone else's account. Take out all the cash you can now to live off until new bank acocunts are sortd out and speak to the Official Receiver as soon as you get the order and make sure he writes to the bank confirming he has no objection to you keeping the account for your wages.
Make sure you don't / haven't paid off parents or family members who lent you money rather than other debts - that can be claimed back.
It may be better to move ASAP i.e. before the bankruptcy if you can as this will avoid any problems with telling the landlord about the bnkruptcy. Won't affect things going forward but may be more difficult to get somwhere iyswim
With utilities if they give you a prepayment meter make sure they do not crank up the maount per unit to claw back the olddebt - not allowed. May be advisable to go with a diffrent supplier in the new place just to be sure.
I assume you and dh are both going bankrupt?

Good luck with new baby - my two are 17 mths apart and it is wonderful (if hard work at the beginning )
