My Landlord sent a section 21 to me by email (which I'm fine with - I want to move out), but due to past disgruntlements on the landlord's behalf and him potentially knowing that we'll be able to sue him after we've left due to him not protecting our deposit in time, there's a chance that he'll mess us around.
He sent us a section 21 by email, and CCed someone from an agency (so he can prove he sent the email), so we can't pretend we didn't receive it, especially how we replied. This agent appears to be from a property services company that specialises in tenancy evictions and getting unpaid rent for the landlord - this was probably because we were withholding rent payments due to the landlord not adhering to section 48 (giving us a UK address to which we can send correspondence) and he wouldn't accept that he was breaking the contract at the time but has since realised this and all has been resolved, so this agent's service is no longer required.
But what's to stop him from going back on his word at the last moment (after we've signed a new contract) and pretend he didn't send it - because I can't really prove that he sent the email right? Unless the agency he CCed will be willing to act on my behalf too? Will they be legally required to?
