I live in a private mortgaged property in Edinburgh. At the bottom of my back garden there is an access lane which 8 different properties back onto. One of the owners of the houses backing onto the access lane is parking their car in the access lane . Can you legally park a car in the access lane overnight or should access lanes be left clear of any obstacles at all times? If it is illegal to park in the lane what action can be taken against the people parking the car in the lane?
