Fight your parking ticket - how to appeal your fine | This is Money
They never put the ticket on my car
It used to be the case that if you received a Notice to Owner in the post, but no ticket was applied to your car, then you could appeal.
For a ticket to stand, previously it had to have been physically applied to the car. So if you return to your car and find that a parking attendant is in the process of writing a ticket, you could drive off without being pursued for the offence. The attendant might say 'I have already started writing the ticket', or may ask that you wait while he completes it, but you are not required to remain at the scene.
Note that this only applied when the ticket is being issued by a parking attendant. Police officers and traffic wardens can also issue tickets, although the overwhelming majority are handed out by parking attendants.
Changes in the rules for parking tickets in April 2008, meant that this defence no longer applies, and councils may now send you a ticket through the post. However, if this happens the first thing you should do is request photographic evidence of the contravention.
If the council cannot supply this, then you can argue the contravention did not occur. Check the photo carefully against the actual area. Has it been cropped to make it misleading, does the picture actually show a contravention, is it marked with date and time, does it definitely show your car? In many instances, there may not be sufficient proof.
