his house is on the other side of our house and no where near our driveway.
Come on OP you can't post about this kind of dispute without a diagram - it's the law.
He then said he was going to cordon it off and block access within a week, which is what his solicitor has advised him to do.
He's bullshitting.
he said he's spent hundreds on solicitors and does not want to deal with estate agents.
Spent hundreds to what outcome? Being told to do something illegal, like cordon off disputed property?
He then said it was still going through the courts, and admitted nothing had been finalised,
What courts? Who is representing your property? How come your agents or landlord aren't aware of this process then? 😂
but then said he owns the deeds so its up to our landlord to prove that he is wrong.
He is the gift that keep on giving. Nobody owns the deeds, the deeds simply exist to prove ownership. If he "owned" them, he's be brandishing them at you. He'd have no reluctance to show them to your agents either. He doesn't want to deal with agents because they won't accept his bullshit, but he reckons he can bully you into backing down with no proof from him.
Please can anyone make sense of this
Yes. A stupid man believes that you - a mere woman - cannot possibly know more about your rental agreement or rights to the space than he does, & thinks that he can impose his will on you by scaring you.
Apart from that you are correct, nothing he has said makes sense - because he is making it all up. He probably feels big talking about his "solicitors" & the "hundreds" he says he has spent.
He hasn't. If he had, your agent would know about it, & your batshit neighbour would be showing you proof.
A few quid will get you a copy of the deeds. Then you can post a copy through his door, enjoy peace of mind, & tell him to piss off when he next harangues you. If he then tries to use or "cordon off" the space, call your agent, remove his crap & put it in the space that actually belongs to him. If he kicks off about it, call the cops.
This situation is really stressing me out
Stop allowing this eejit power over you by responding to him as if anything he says is true. He needs laughing at. The sooner you can start viewing him as a ridiculous imposter, the sooner you will stop feeling anxious about him & his stupid performance.
