Tell me please what fresh hell is this?
Of course there is a backstory but it culminated with dh being threatened today 
We live on a new housing estate, we share the entrance to our driveway with two other families....
We have owned the house for 8 years but it has been rented out while we've been abroad. We just recently moved back and discovered that no one now living here is aware that it is in fact a shared entrance but not a shared drive. The parking has been pretty bad and I've had to knock on my ndn1's about 5 times to be able to leave my property as she was parked on it. Interestingly enough this seems to piss my neighbor off 
I had been getting some building work done, it took about 6 weeks. I informed my neighbors beforehand and wouldn't allow work after 6pm in order to not put the neighbors out to much.
A truck dented my neighbours (2) fence i got it fixed immediately and was mortified and apologetic.
A delivery truck was blocking the exit once by about 5 inches and my neighbor 1 went batshit at me in the street. It was the same neighbor who was consistently blocking me in and i was only ever nice & polite to her when she was on my property
My ndn2 stood out on the drive with her dh and dm and shouted over to my gardeners that i was a disgrace for having building materials on ndn1's drive.
Still with me?
When the work was finished i took round wine and a card to both neightbours (i also arranged to get their windows washed to clean any builders dust)and thanked them for their patience. In the card i attached a photo copy of the property boundaries for their information and so they would realise that they were in fact parking on my drive and that I wasn't storing property on ndn1's drive that it was in fact my
property.
So that's the back story ... now this is where it starts to get nasty.
Just to make things better we live opposite a school.
Sometimes a random blocks the drive entrance and uses it as a parking space. Last week i lost my rag and put a note on the windscreen with Pratt stick saying RUDE - this isn't a parking space. (Fucking bastarding mumsnet giving me these ideas)..anyway turns out it was ndn2's visitor...I didn't know 
...it made no sense, why would he park blocking when the neighbor had 2 spaces on his drive???
Anyway the ndn 2 stopped speaking to us (which really is ok because they were never very nice to us anyway), but unfortunately they added in talking about us loudly so we overhear , stink eyeing us, ignoring us when we greet them....sort of a pack mentality when they have. Visitors...sort of low level intimidation but very unpleasant.
The council put in keep clear signs at our drive entrance yesterday - i requested them about 6 months ago. The ndn2 has gone apoplectic. Now they don't park on their drive at all, they are parking both cars at the entrance to make it difficult for us to leave.
They've now set up toys for their D.C. On the entrance so we would have to ask the D.C. To move them temporarily while we exit.which we did, politely of course...
This has resulted in non dh going mental 'squaring up" pointing in my dh's face calling him names, taunting him, telling him hit me hit me go on...my chest just kept very calm with his hands behind his back....ndn's poor poor ds was crying terribly it was awful begging him to "leave it dad please"....when people walked by the ndn doh cuddled his boy and said to my dh...look what you've done to my poor boy you're scaring him 
....
I have no idea how to deal with this situation.
Any help please?
