^^^^^^^ Sorry, but I think thaayt's wrong.
Once a "vehicle" has been left for work to be executed,the repairer has a Lien over it.....on effect he becomes the ownerand keeper.
in practical terms, the repairer is charged with the responsibility of taking good care of the vehicle and is the temporary owner until the bill is paid.-or until a judgement is obtained in the Court.
The lien is broken if the vehicle is released to anybody...pursuit is then through the County Court.
