What do you mean by 'disputed' ?Are you saying that you have no idea what this debt is supposed to be for? That is, you've no idea who the person or company is that is claiming the money or why they are claiming anything? Or are you saying 'Yes, I did have this transaction: purchase or contract or services, or whatever, but I don't owe anything now, or don't owe as much as claimed', or what?
It could be a con.Write back and ask this 'lawyer' which Court the proceedings were issued in and to give a court reference number to identify the claim.Nobody can get a CCJ (County Court Judgment) without proceedings , that is a claim, being issued in the Court. It's all done through the Court. You'd know that the claim had been made because you'd have got a copy of the claim from the Court itself with time to acknowledge you'd got it, and asking whether you dispute the claim in total, deny it, or if not, whether you accept that you owe part or all of it. You'd reply to the Court and put in a written denial of the claim , sent to the Court.
Whatever these people say they can't get a CCJ without issuing a claim through the court (as above).All sounds very fishy, does this!
