Land boundaries - no man's land
In Wales...We have a house that backs onto multiple fields, and there's fencing up at the edge of the field, but a bit of land, about 3/4m between where our garden "naturally" ends (there's an embankment down to a stream at the end, and the fencing for the field is about 3/4m beyond the embankment/natural end of our garden. We don't have a fence, as many of us don't, as the view is quite nice. A few (14!) years ago we had a massive problem with Russian Vine, choking the shrubs and trees in our garden that has come from this bit of wild land between what we thought was the end of the garden and the field fencing. We approached the council who just told us to do a land registry search. We paid, and the map of the outline of our land is not really conclusive (it's quite zoomed out with a really thick red line). We have taken it upon ourselves, with neighbours, to tackle the vine that had spread five houses across. We've been maintaining that wee bit of land now for a long time, as have neighbours, it's absolutely wild, but are just trying to keep on top of the vine. Next door moved in a few months ago, and have just built a fence (which is not that usual where we are) right up to the fence of the field. No-one has an issue with it, but it has got the other neighbours as well as us, wondering if we have any entitlement to that wee bit of land too.
For a bit of added drama, a few months ago in winter, we had young lads walking up and down the length of the steam and climbing into gardens (maybe that's why neighbour fenced it in to be fair).
We've lived here 15 years, have been maintaining the bit at the back for about 13 once we knew we'd have to deal with the vine ourselves.
We've in the last month heard that there will be a development in this field. No word on what it might be, just that the land is up for sale, likely housing. We love this wee no man's land, as it's full of nature, and wouldn't want to turn it into some astro turfed tundra.
Very long winded way of asking if we should try to establish a boundary at where the field fence is, which we actually aren't sure is ours.
