If you have received a National Mileage Register (NMR) request letter for a vehicle you have never owned, please complete the online form and complete the question relating to the ownership of the vehicle. This should take you no more than 2 minutes, and will help us to complete our investigation into this vehicle's mileage. Your details have been provided to us either by the DVLA or from the company requesting the mileage investigation on the vehicle having taken them from the V5 registration document. You may want to write to the DVLA to ask for proof that you are not the registered keeper of the vehicle. You should provide as much information about the vehicle as possible. The DVLA will update their records and send a letter of confirmation to you within 4 weeks.
