I am hoping somebody could offer some guidance about the correct way to document a recent change to our access arrangements. By way of background my home and my neighbours was accessed by about 10 feet of shared drive off the road, which then led on to 2 separate areas of drive, mine house on one side and my neighbour's to the right. The legal boundary between both properties runs between the houses and continues up the centre through the shared access - each property having a legal right to drive on each other's side of the access area before branching towards our respective houses. Over the years I have suffered persistent ingress from previous occupiers of that house to the point where on an almost daily basis I have been unable to get in or out of my drive due to the access area being blocked in some way. Luckily last year a new family moved in and we no longer have those problems (but they will not stay for ever) so we felt now would be a good time to tackle things permanently - in agreement with my new neighbour I have just invested in works to create two private entrances with a small fence demarcating the legal boundary. Everyone is happy and the two properties are now totally separated with their own entrances.
So I now have one final detail to deal with - it is important that the previous joint access arrangement at the top is now negated and the new arrangement recorded on the Deeds. My question therefore is could someone please advise on a way to get the change legally documented - due to the likely high cost of a solicitor I was wondering if there is a possible DIY route via the Land Registry or if this is too complex to do oneself. If a solicitor is a requirement I would be grateful for any recommendations, I'm not sure if I should approach a normal conveyancer or if I would need to go to a specialist solicitor.
Thank you in advance for any help or advice.
