I think you will be ok but I agree with Paul that you need to inform your IP.
Sharing from experiences of dealing with debt
The greatness of a man is not in how much wealth he acquires, but in his integrity and his ability to affect those around him positively.

It may depend if the IVA is seen (as it some times as BR) I know this as we have just gone though this for my husband. I was able to act on my husbands behalf because my IVA is almost at the end of the 6 years (Nov.2011) We went to a private company who does this work and people who are BR are not able to act in an EPA. The guy who set ours up said it was to safe guard the person form people who may take their money (which I know is not the case) but it is not unheard of for distant family members to do that.
Sorry to hear about your husband we are getting to that point with my husband, Take care

Nothing you can buy feels as good as not being in debt.
