Title plan incorrect

We are purchasing a property & the title plan is incorrect in that it looks like the neighbours property encroaches on the driveway so we would not have access to our house. In reality on the ground it is not like this at all. Our solicitor has said if we proceed we might not be able to sell in future. The vendor contacted Ordnance Survey who agreed it was wrong & changed their master map. The vendor then contacted land registry again to request an amendment giving photo evidence & the new OS map. .LR still refuse to change the title plan even though it’s totally wrong & now totally different to the OS plan.. the neighbour’s property has clearly been plotted in the wrong place. All properties have been there 100+ years. Unless this can be rectified we can’t proceed. What are our options? I have read that sometimes LR can make an entry on the register explaining about the register - how likely is this? We are concerned if we go ahead we will have the same issue as the current sellers in the future & potentially have an unsaleable property. I have attached the title plan showing the obvious error on the driveway along with the new updated OS plan showing how it is in reality & a photo clearly showing where the neighbours property is positioned to the right of the drive. Any advice please? Can this be sorted?

Morning Mrs Pentelow - I'm sorry to read of the issues you are facing. Title plans are very rarely amended simply to match any OS changes, especially if the registered information matches what was originally applied for and registered. Moving an OS line simply confirms what OS have seen when surveying the site. It doesn't confirm legal ownership. It reads to me that the most likely solution is for the registered owner of the 'wrong land' so to speak needs to transfer it to the neighbour. The other alternative is for the neighbour to claim ownership of the land and apply to register that claim. The 'best' option is invariably the transfer of part from one to the other. But do rely on your legal rep to advise and confirm
