I used to live in house in a terrace of four. Between my four and the next four along, there was a joint driveway that we could use to access our garages at the rear of our gardens.
In our deeds it clearly laid out responsibilities for this driveway. Those with houses on either side of it had responsibility to maintain and keep their half clean and clear, and we - the rest - had similar responsibilities for the area directly outside our garages at the rear.
A very 'loud' couple and their two older teenage sons lived in one of the house on one side of this driveway. Most of us used our rear garages as store rooms, and tended to keep our cars off street on front of the houses areas.
However, one time I was planning on doing a car boot sale on a Sunday, so loaded my car and put it in my garage ready to drive out very early that Sunday. These people used the driveway area next to their house and close to the road as their own private parking area. On the occasions when I wished to use it I would knock and they would move the car they left there, but as I was going out so early I went to them Saturday afternoon to tell them to keep it clear for me.
They got quite abusuve, telling me they would park there whenever they wished as they 'owned' that driveway!!! I told them they should check their deeds (or talk to their Solicitors), as they most certainly did NOT, BUT....did have maintenance responsibilities for it. Got a lot of verbal for that at the time. However, they obviously did follow it up, as, after a few weeks, they kept it clear of cars. However, whenever I went past their house, if the 'boys' were outside they would start swearing at me.
I was not the only person in our little (normally pleasant Close), to suffer from them, and much to all our delight, they eventually put that house on the market and went away.
