I received a letter on Friday 14.09.12 informing me that DVLA are taking me to court. On 07.01.12 I part exchanged a car which had a private registration on it. I paid the garage money to transfer this on to a retention certificate for me. I received a letter from DVLA a week later confirming I was no longer the registered keeper of the part exchanged vehicle. On the 19.09.11 I moved house and changed the address on my driving licence about a week later. All the corospondance from DVLA was sent to my old address so things have been held up as I only visit my old address every few months to pick up any mail that may have been delivered there for me. The summons I have received from DVLA is for a registration mark that may have been origanally on the car that I part exchanged before I put the private registration on (about 8 years ago so I really can't remember what the original registration number was), although the make and model are the same as the car that got part exchanged. DVLA are saying that because I haven't re-registered the vehicle they are taking me to court. I have contacted the garage with whom took my car as part exchange and as yet they haven't returned my calls. Am I really responsible for re-registering the vehcle even though the garage own the car and i have a letter from DVLA saying I am no longer the registered keeper?
