Can your neighbour access his land at all with you parking on your land?
Does the right in the deeds specifically refer to access to use the two garages?
Does the right refer to vehicular access?
If not and if the neighbour can still access his land when you are parked on your land it will be down to your neighbour to establish you are unreasonably obstructing the right of access.
Unless the right is specific then I think your neighbour's argument is weak.
Do you have any further questions?
Please accept my answer and I'll be happy to answer any further questions you have.
Do you have an electronic copy of the deeds which you can attach for me to read?
There is nothing in your deeds stating how much access you have to give your neighbour. If you can install a fence leaving reasonable access then I cannot see what your neighbour can say about it. The right on his deeds will be similar, you can buy them from the Land Registry to establish this.
You neighbour only has the right specified. There is no specific right for a 20ft wide access to be given. It also does not say that you have to provide sufficient access to allow him to park where he wants to.
You could erect a fence if it leaves reasonable access then you are not doing anything inconsistent or contrary to the rights in the deeds.
I can take a look at the 86 conveyance/transfer if you get a copy.
The neighbour 's land is then unregistered.
Can you add it via the paperclip?
