Firstly forget about paying the PCN at the £65 rate, we want to explore all possible avenues for getting it cancelled first.
However before we get to that, you need to deal with the Charge Certificate. A Charge Certificate cannot be challenged, but the next document in the process (the Order for Recovery) can be, under the statutory ground that you never received the Penalty Charge Notice.
Have a read of the process on this page
Where a Enforcement Authority believes that a moving traffic contravention has occurred, it may serve a Penalty Charge Notice on the person appearing to them to be the owner of the vehicle. This is...
from the "
Charge Certificate" paragraph down to the end of the page.
Obviously the PCN didn't turn up so it's possible this might happen to the Order for Recovery, so you don't want to rely on the post. Instead, keep an eye on the amount due on the council website, once the debt has been registered with the Traffic Enforcement Centre, the amount owed will go up by a further £9. At that point you are able to make a statutory declaration, even if you haven't received any further paperwork.
You just need to print off form PE3
Form PE3: Challenge an unpaid penalty charge notice.
and note that, counterintuitively, the box under "
My reasons are (give full reasons)" should be left blank.
You will need to make an appointment at your local county court to get it sworn, or most high street solicitors will do it for £5 - £10. Note that you must not sign the form until the person witnessing it tells you to.
Once that's done, you can scan or photograph the form and email it to tec@justice.gov.uk with the PCN number in the subject line.
If anything isn't clear, please ask.
