Not entirely the same thing but i wrote a letter to the DVLA informing them of a change of ownership of a car because i kept recieving fines etc for it not being taxed. Sold it to a "mate" who just fucked around and never registered it or sorted it out, was sick of getting reminders about it. Got a letter of confirmation back and that was it sorted. P.s if you read this "mate" you'll know the car. There's probably an address on the website for this.
