What do I do with my log book / V5C now my vehicle is a total loss?

As the registered keeper it is your responsibility to notify DVLA that you no longer own the vehicle. To do this simply follow this link https://www.gov.uk/sold-bought-vehicle Alternatively this can be done by post, Fill in the yellow ‘sell, transfer or part-exchange your vehicle to the motor trade’ section of your log book (V5C) and send the perforated section to:
