Many people are frightened when faced with the threat of Court action, even if they know that they have a perfectly good defence to the claim.
Being sued is not the same as having a County Court judgment against you – you may very well win. If you are in the right it is very easy to turn up to the appointment at Court (a private room, no fancy costumes and little formality) and explain your side of the story.
You don’t need a lawyer but you should take along any paperwork (with extra copies). It is also a good idea to make a short list of the points you wish to make. The system is there to help you – don’t be afraid.
