its likely not like TV court, It's likely to be you, your lawyer (you do have a lawyer don't you?), the defendant and their legal representative in a small room with no-one else. Rock up with plenty of time, dress well, be polite and do what your lawyer says - worst case you lose and the insurance has to pay out, best case you win and you get your no-claims and excess back (+ reasonable expenses iirc, keep your parking ticket to add to it

We went a few years back when my wife had a head on down a country road, we rocked up dressed for a funeral and the defendant in her Day-Glo leggins - She was rude and unhelpful, we were polite. Judge ruled 100% defendants fault as my misses had tried to drive into the hedge and the defendant hadn't made any effort to avoid the crash. Could easily have gone 50:50 but think the appearance and attitude helped a lot
