Oh don't worry they wont show. They will send a settlement letter prior to the date or possibly as they did with me it will be waiting at court if they are really chancing their arm.
How did I prepare?
I read up on the laws I listed in my claim. You can find them online pretty easily and made sure I had copies of the relevant bits. I had Bank Fodders script from the Going to court Library and a copy of all letters from both parties. My strategy if it came to it was to do the Columbo "I'm sorry I'm a bit stupid but..." schtick As everyone keeps saying they won't show.
