My Fiancé recently recently visited her mother's old address Neighbour, who gave her a Notice To Keeper Reminder Notification PCN Letter, they had received.
Her Parents have not lived at the address since November 2024.
The Date of Breach on the letter shows 24th July 2025.
The Driver, according to the PCN, had exceeded the maximum stay period captured by ANPR.
First of all, are there any grounds for an appeal here and secondly, due to her not receiving the original PCN, do we have any grounds for initialising the original Notice To Keeper PCN, for which the discounted amount would be Liable, as we hadn't received anything up until this point of contact.
Any help, as always, is greatly appreciated.
