I understand the difference between the two terms but how can you ensure legally that the owner is definitely the owner should they not be the actual keeper of the vehicle? The way I see it and also here, http://m.askthe.police.uk/content/Q743.htm , the person who essentially uses it and is therefore responsible for it should be noted as the keeper and have the v5 in their name. But how do you go about proving someone else owns it. The background behind this is I don't want to own my car just simply use it. Ownership will be passed on to a relative. Do I just make up an invoice and we both sign and date it?

 

all i would say is have a look at laws concerning depravation of assets
anybody" buying" from you would perhaps have to prove where they got the funds-if thats the aim....
if you sell it at too low a price it would look like depravation-the councils etc look at property,savings etc but as yet dont really delve into motor vehicles
most insurers will want the vehicle registered and owned by yourself too
