Shadow Systems said "Like if you make a request to know whom owns the vehicle with plate $XYZ123 & the department of motor vehicles sends you not only the owner's name, but address as well." Not any more, here in the UK. I asked for owner information for an historic vehicle I was restoring back in 1990 and was given chapter and verse, names, addresses, dates of acquisition, MOTs, etc. etc. This January I asked for the same information regarding another vehicle, but was met with a firm refusal, all they are willing to supply me with is the anonymised dates of change of ownership.
AK Stiles said " The council will know this from the council tax record for the property (single occupant pays less than multiple people occupying, zero occupants pays less again I believe)". Again, not true. Single occupancy attracts a 25% discount on Council tax, but a vacant property is only exempt from CT for a limited time (two years I think). My next door neighbours fell foul of this when their mother died, they left the house empty for a while, intending to do it up and sell it, but after two years they were presented with a bill for double Council tax. The council explained that this was to dissuade owners from leaving property empty and thus reduce the number of families looking for property.
