Do they belong to the property or to an individual? MIL's Neighbours are on about having a right to access a path on a corner of her land because they have had access to for 20 years. PIL complained to them but they kept walking over the land because it meant they didn't have to walk so far from garage to their house. They are claiming an easement because of this, but haven't registered it with Land Registry. They are in council house, but MIL has private property. Can they claim an easement if they are tenants? I think they are trying to intimidate MIL since FIL died, so would welcome advice.
We provide an online Practice Guide which deals with easements claimed by prescription www.landregistry.gov.uk/professional/guides/practice-guide-52#guide-mark-5 Whilst it covers a number of issues, some of which might be more pertinent to your neighbour, and aimed at conveyancers it may be of interest to you. Section 2 especially explains how such rights can be acquired.
