Cutting a boundary conifer

True, and we had a problem with that. Unfortunately it is rarely possible to determine the boundary line unless the original markers are still in place. Land Registry told me that the thickness of the drawn lines on Land Registry documents/maps can easily cover 18" of land. I don't know if modern registry is closer than that.

We were able to trace our boundary by finding the original angle iron posts that were hidden in a laurel hedge that was 8ft wide, which had spread into both gardens.
