Thanks for all your help. Im very new to this all do you mind explaining what a NTK is and when I shall receive it?

Yes it was a yellow sticky pouch in the window. I've read that it is advised NOT to appeal to the parking agency but to the landowners, correct? What happens if you just ignore it altogether? And what do I do once i receive a POPLA number?

Hi, I got a ticket today at my university campus, the car park is always full and therefore is always cars parking in places which arent designated spots, unfortunately today I had to be one of them cars and got a ticket. It was for literally half an hour, I was slightly on a yellow box in the car park but was in no-ones way and did not deny any access. The ticket is from a private agency 'Car Parking Partnership' and after some research I can see that some people are saying I am not entitled to pay the fine. Apparently it is unenforceable. Can I please have someone with knowledge / experience on this issue to shed some light on the situation because I really have no idea whether I should just ignore it or not. Thanks a lot. *edit - I understand these questions have been posted before and I'm sorry but I wasn't sure if by chance the laws have been updated so I wanted a recent view on the matter.
