If we understanding the question correctly, your husband is negotiating a debt management plan and you don't want to show the debt managment company or creditors those accounts.

The issue you have is your creditors want to know what your husband earns. To do this you'll need to show them proof. When your self-employed, these would come in the form of accounts.

We would never advise you to mislead your creditors in any way. If however, he had decided not to be self-employed any more and had recently got a new job and was waiting to start and the future employer had given him a letter saying what he was going to be earning and when he was going to start, then that might be enough. Or even just a few months being employed with a wage slip. That is likely to do as well.

There are many things this depends on. The main problem may be that he owes money to the bank he has his business account with. This can be sorted out. Try to get advice from as many people or companies as you can.
