In answer to your questions:
1. Why have you only left it until now to try and get 'Your Parking Space' involved? I seriously doubt they will be much use as ParkMaven have instructed DCB Legal to start litigation. You can still try and find out what went wrong with their system but, to behest, it is not going to make much difference in this case as DCB Legal will discontinue in due course.
2. No, HMCTS (Her Majesty’s Courts and Tribunals Service) does not routinely send legal documents via email unless expressly permitted by the court. Court documents, including claim forms, directions, and judgments, are typically served by post to the address provided in the court proceedings.
However, you may request email correspondence by writing to the court, but this is at the court’s discretion. The best approach is:
(a) Contact the Court – You should email or write to the court handling your case, requesting that all correspondence be sent via email while you are abroad. You should provide a valid reason (e.g., temporary absence from the UK) and specify a preferred email address.
(b) Appoint a Representative – If you have someone in the UK who can receive mail on your behalf, you may wish to appoint them as a representative to monitor your correspondence and update you on any deadlines.
(c) Check the Online Court System (MCOL) – As the case will be in the small claims track, you can check the Money Claim Online (MCOL) where updates might be available.
(d) Request an Extension if Necessary – If you expect to be unable to respond to deadlines while abroad, you may apply for an extension under CPR 3.1(2)(a) for case management purposes.
(e) Inform HMCTS of a Temporary Address (if applicable) – If you will have a reliable overseas address, you may inform the court, though this is not always ideal due to international postal delays.
Option (b) is probably the best if it can be arranged.
3. Don't bother responding to a two year old email from DCB Legal. They will receive a copy of your defence from the CNBC and will respond stating that they have received it and intend to continue. If you do want to make sure you only receive email correspondence from DCB Legal, the email them at info.dcblegal.co.uk and give them your email contact and the claim number. Don't give them your phone number as they will be a nuisance as the claim hearing date nears and they want to settle. (don't settle. They will discontinue).
I will come back with a suitable defence over the next few days. The one we have been using has now been amended and I just need to clarify a few details with the judge who is advising me.
