I had this situation with my lease company. Some important points
Read your lease contract carefully and find the section that deals with parking tickets
What you have is not a “fine”. This is massively important and your dealings with the lease company hinge on this. Private parking companies cannot issue a “fine”. They can give you an invoice for alleged breach of contract. Never, ever refer to it as a “fine” when you’re dealing with the lease company
My idiot lease company paid £1,300 of parking tickets without consulting me then hit me with the bill. Took a lot of arguing to get the money back. My lease contract had the following clause
10.1 In respect of any responsibility, claims, liabilities, losses, damages, or expenses, including legal fees and any liability resulting from legislation for the payment of fines or penalties for parking, driving or similar offences or contraventions in connection with Vehicles (the “Liability”): (a) ARVAL has no responsibility for the Liability; (b) the Hirer accepts all responsibility for the Liability including taking all appropriate action; and © the Hirer indemnifies ARVAL and holds ARVAL harmless against the liability, ARVAL shall be entitled to charge the Hirer a reasonable administration fee for any work carried out or documentation processed relating to the liability.
The bit in bold was key. Legally a private company cannot issue a fine or penalty, so this clause had no relevance for private parking tickets, it only applies to tickets issued by the council or police. Took a long time to get the parking company to accept this. In reality they know it to be true but most people don’t fight it. They eventually admitted I was right and gave me the money back.
(no doubt someone will say I shouldn’t have parked where I did, but I was parked on my own land where no private parking company has any authority, but this has been an 8 year battle against these crooks)
