A very long story cut short, in 2015 I applied for a joint IVA with my wife to Knightsbridge insolvency. They said creditors had rejected the proposal however an IVA could be made in just her name. I noticed in 2017 they had actually registered an IVA on my credit file and after an issue arose whilst trying to sell our house, we found out that my wifes IVA was invalid because within the IVA, out of 5 accounts, 4 were actually mine and one could not be confirmed so was written off. This means they registered an IVA on my file but one was never even created, and they created an IVA for my wife by using my actual credit accounts, not one account in her IVA was valid and in her name! this has caused Huge problems for us so we want to do something about it such as sue/claim I don't know what to do, who do we need to speak to? A financial lawyer?
