Legal advice?

[WiNgNuTz]

Ok, i have an issue that i would like to get some advice on, and figured here would be the best place to start, especially as we seem to have some people on here that are knowledgeable about legal things.

Some of you may remember my old China 1.4. Now this car was bought from me by some "interesting individuals" (Read: pikeys) and scrapped, and despite their appearances, went about business in the correct manner, ie. gave me all the relevant details for the v5c, which i then personally put in the post (so i know it got sent off). This happened in March this year

Then, when the tax was due on the 1.4, i received the usual form to retax or sorn the vehicle. so i rang the DVLA. They informed me that they had not received the v5c informing them of the scrapping, so advised me to send the tax renewal form back to them with a covering letter explaining that i'd sent the v5c back, and what date i sold the car. So i did.

I then received a confirmation letter dated 6th sept, saying they'd updated the records. Sweet!

Unfortunately, that was not the end of the matter. I received a letter last week summoning me to Watford magistrates court on 21/01/2013, saying that on 19/06/2012, i was the registered keeper of the 1.4, which "did not meet the insurance requirements".

Now, my question is this....

Have i got a leg to stand on here, or should i just go with it and hope for the best? Baring in mind, between getting the tax renewal form, and the summons, i have heard not a bean from the DVLA or anyone else on the matter.

Please help, i could do without this to start 2013 off!
