Hi dso
If I have understood your question correctly, your IVA was based upon you contributing an aggregate £16,000 over a five year period, and you have already paid £5,000 towards that.
Your creditors may accept a lower sum than the £11,000, as they could discount the benefit of receiving a final payment earlier, and of course there would be savings in IP fees as well. You should ask your insolvency practitioner to give you a settlement figure based upon achieving a 33% return to creditors now, and then see if there is any further room for negotiation depending upon your current circumstances.
Where is the lump sum coming from as a matter of interest?
