Hi tomk
The answer to that is not at all, but your IP will need to know what her earnings/benefits are so that he/she can make an appreciation of what her fair share of household and living expenses should be.
You will need to work out your family income and expenditure, ensure that you are paying shares of the joint expenditure based on the same ratio as your incomes, to see what disposable income you as an individual have remaining. Once this is known, then further advice can be given.
Do bear in mind that the student loans will have to continue to be paid, as they are outside insolvency proceedings.
