Court documents received!!

[Wave_Rider]

I received a PCN from armtrac on my car Jan 2017 for parking on an access road to my gated permitted residential car park, parked in access road as gates to car park were broken (went out early next morning to move car and found ticket); refused to pay as not our fault etc and in any case also realised that the no parking signs were all at the entrances to the residents car parks (access road serves 3 Apartments blocks each with private parking) and didn't mention the road at all - no road markings on road which just looks like a normal road. Continued to defend actions to armtrac then Gladstone's and have received court forms this morning... Genuinely think it's crap but the forms are scary!!
Advice for filling forms please...??
