There are many ways of course to prevent a right of way being established over your land. 

Physical obstruction, erection of gates, permitted user - all will work if done right. 

Another way is to lodge a notice pursuant to s 31.6 of the Highways Act 1980. 2013 Regulations later provided a prescribed process of how to do this thus ensuring that you could be certain you would be protected.

However, many landowners were advised not to use this process. The problem was that it required the Local Authority to erect a public notice on the land that a s 31.6 notice had been lodged. Many landowners feared this would flush out would-be claimants. 

Good news for landowners. 

New 2016 Regulations which came into force last December remove the requirement for site notices for 31 (6) notice.
