Without going into too much detail hopefully
We live in a small hamlet. For at least 40 years in living memory residents of the hamlet (between 1- 4 households at varying times) have had access to a major road via an unmetalled track across land owned by a (very very very) large estate.
As far as we know the person who made the track originally (long deceased) never asked permission from the landowner (therefore there is nothing in writing), but went about it fairly blatantly, and the track has become so well used over the last 40 years by the hamlet and other locals 'in the know' that google maps has (mistakenly) shown it as a genuine route for around 3 years.
This has recently resulted in an increased volume of traffic (maybe 10 cars a day on top of use by the hamlet) using it as a through road as directed by google maps.
Today (on Easter fecking Sunday!) someone (presumably a representative of the landowner) has blocked each end if the track so it can no longer be passed. This has put approximately 10 miles each way onto the journey of people living in the hamlet to reach the major road.
Can they just do this with no warning? They are one of the biggest landowners in the country so we have no hope of winning any kind of legal battle without pots of money or a absolute blatant disregard of the law.
