This is a toughie.
Although you haven't really committed an offence etc some jobs do credit checks as a character reference (bit harsh i think) and (like my job) if you are in enough debt to become bribeable etc.
Some employment contracts state that you can become sackable if you do enter an IVA as well as bankruptcy.
I needed to get Security Clearance at SC level and they did a check, obviously i failed so they sent me a financial questionnaire which is basically like an I&E form so that they can see if you are under enough financial pressure to be bribeable or not. I did get the clearance in the end, subejct to a review after 2 years. Clearly my debt will have reduced a lot in that time.
You are best asking to be honest and being upfront. In the majority of jobs it wont be a problem. in my case if i had lied and they had employed me and found out i would have got sacked for gross misconduct.
Just be honest and you should be ok
