A Certificate of Destruction or CoD:
There are two types of CoD:
The ATF enters the vehicle details onto an online system.
The registered owner will receive a printed CoD a couple of weeks later from the NVDF.
Completed in triplicate with one copy provided to the person depositing the vehicle at the ATF.
Proof of ownership is required (for example the vehicle log book and/or ID).
If you have more than three whole calendar months remaining on your tax disc you can claim a motor tax refund (Form RF120).
You should always get a CoD or the ownership transferred. Without this, you still have responsibility for the vehicle.
