MIB - men in black??
I had a bit of a scare when I bought an old SORN'ed landy - I just assumed that the SORN would transfer (luckily, I checked the small print on a logbook the day after and discovered I had to reSORN it).
Phoned DVLA; According to DVLA you should send in a SORN request form with the logbook when you send the logbook in with your 'new owner details (even though it's the old owner who sends the logbook in).
So I asked DVLA what to do; they said to wait 'til I got he logbook back and sort it then; having got the logbook, I logged on to DVLA online to SORN but it would only let me SORN from the 1st of the month (and I'd bought the landy on the 28th of the previous month), so phoned them again and was advised to write a letter to the enforcement dept explaining the 2 days between buying and SORNing.
anyway, managed to get the enforcement dept on the phone and they said they wouldn't fine for those 2 days (phew!).
didn't relax until I received the SORN confirmation in the post (and no fine) a few weeks later.
I swear they design these systems to induce maximum stress / make the most money.
