It is correct that the DVLA deliberately states its record as being that of keepers, not owners (although the two may at times be one and the same). However, they contradict themselves when they state that if you sell a vehicle you MUST inform the DVLA without delay. Moreover, if someone wants to tax a vehicle, without being the keeper or owner then he/she may be refused that service, particularly if the insurance and registration document is in two different names. The consequence is that, for example if you are the owner, your son is the keeper, but you want to insure and tax it for him then "the system" will refuse to cooperate with you to maintain that position - even though the system was ostensibly designed for precisely that. They are trying to avoid resposibility for sorting out ownership arguments while ensuring who is responsiuble for infringements (speeding, parking, etc.), yet they deliberately meddle in things in a way that implies another aim. Thus, in practice, the DVLA is trying to do two things at once and achieving neither - the system is a mess that, to my knowledge, is unique to this country.
