You are the one that is signing your IVA proposal confirming that the figures are accurate, and it will therefore be you who will suffer if creditors find out that false figures have been put forward.
If the IP has done this deliberately, I suggest that you find a more reputable company to work with. Creditors are currently auditing proposals put forward by various firms, in an attempt to stamp out inappropriate practice such as this.
