It seems to me that what you are proposing for yourself is not right.
You, as Melanie says need proper professional advice.
You have mentioned that you and your wife are considering a joint IVA (probably single but interlocking).
I would transfer your wages and those of your wife's to the account that is not overdrawn.
All other debts that your wife and you have can be dealt with by either an IVA/DMP whatever is the most appropriate advice given by an IP.
As mentioned you need to have a chat with an IP and give him/her details of all your personal(and your wife's)financial circumstances and particulars.
Visit
www.iva.com for reviews on firms and practitioners and select one or two to have a chat with. They will give you
the most appropriate advice and it is free.
