Nothing you have shown us makes any difference to anything. However, I would suggest you take much more care to redact your personal information and VRM as you are easily identifiable from what you’ve shown us.
The lease company did not correctly transfer liability to you. This is evidenced by your earlier evidence of their mention of TE7 and TE9 forms they expected you to complete that are not relevant to private parking charges. Had the lease company correctly transferred liability to you as the Hirer, that would have been the end of the matter as far as the lease company was concerned.
Had the correct procedure been followed, both by the lease company and ECP, a Notice to Hirer (NtH) would have been issued to you, in your own name. Together with that NtH, should have been a copy of the NtK, a copy of a statement signed by or on behalf of the vehicle-hire firm to the effect that at the material time the vehicle was hired to a named person under a hire agreement, a copy of the hire agreement and a copy of a statement of liability signed by the hirer under that hire agreement.
None of that has happened. Without any of the above having taken place, you cannot be liable as the Hirer. Only the driver can be liable and, unless you’ve told ECP the identity of the driver, inadvertently or otherwise, they have no idea or proof of who the driver is. They are not allowed to assume or infer you must be the driver because you are the Hirer.
So, for now, you continue to ignore the useless debt demands from any debt collectors. The debt collectors are powerless to do anything. You were advised very early on to ignore them. We do not need to see their useless letters.
You were never the Registered Keeper (RK) of the vehicle. You were only ever the Hirer. You may or may not have been the driver but that is not for you to prove. There is no legal obligation on the Hirer to identify the driver. The burden of proof is on ECP to prove the Hirer was also the driver. They can’t unless the Hirer tells them, which you’ve been told you are under no obligation to do.
This is what is going to happen.. . You are eventually going to receive a Letter of Claim (LoC) from DCB Legal (not DCBL). After that, you will receive an N1SDT Claim Form from the CNBC. We will provide advice on how to respond to those.
The claim will be defended and eventually, the claim will be discontinued. That will then be the end of the matter.
So, ignore all debt recovery letters. Show us the LoC and then the Claim Form when you receive them for further advice.
