I'm with Eleanor on this - if they begin to sue you they will have to give you copies of paper/micro-film documents that explain and verify their claim. They will have to give you these after they begin court action against you (and this is partly why they are unlikely to begin court action against you).(posted 8461 days ago)They do not have to give you paper copies under the Data Protection Act but they do have to give you legible copies of electronically stored info. You can force them to do this whether they are suing you or not.
So what you should do now is write to them as Eleanor has said but make sure you say that you are requesting sight of the documents under the Civil Procedure Rules.
They'll probably refuse, which will be a clue that they have no intention of suing you - because they know they have to be seen to comply with Civil Procedure Rules.
