There are a number of creditors who are currently rejecting proposals where the mortgage and secured loan payments are more than 40% of salary. If this is what you mean, and your is higher than this, then you will need to seek the advice of your Nominee as to whether your IVA is still viable.
Cybus makes a good point - the creditors can work out the percentages for themselves. I have occasionally put forward an IVA proposal with higher ratios, but always clearly explained the reasons for doing so in the debtor's proposal rather than my nominee's comments.
