I basically do not feel that in signing the form that you cause yourself any difficulties. In terms of protecting your privacy, the DTI's Individual Insolvency Register is available on-line for anyone who cares to search it, and they are much more likely to do that than to do a Land Registry search.
However, where does it say specifially in the IVA proposal that you will undertake to sign the form? If this is not mentioned, then you don't need to sign it if you don't want to.
This form is just a formality, and if I were your IP I would think that you were being uncooperative if you refused to sign, when this was an express term of your proposal.
