I think our paperwork shows the registration info of the person who registred it. Like in UK this is not ownership by itself. The paperwork also has a section for any liens on the property. This can be the creditor from the beginning or a private person or a government entity can have a claim due to debts. Nowadays these are all in the system of course. The paper card does not mean anything. Everything is looked up on the spot.
A vehicle's registration papers show the keeper's name and details but the document states in large letters "This document is not proof of ownership".
