It is not rare for two people to each own a tenement (often a parcel of land) next to each other, not knowing exactly where one’s ends and the other’s begins. With buildings, this is not as big of a problem, for they have walls. But with parcels of lands, the parameter of lands is usually imprecisely indicated by the position of decade-old trees or old rubble walls, and therefore, the problem of boundaries is much more common. And as the defiled saying goes: for every problem, there is a lawsuit.
This is not just a problem of our time. Since Roman times, there existed an action at law for situations where the boundaries of contiguous estates were uncertain. For many of us, a border is simply the notion of separation between two spaces, but for Ancient Romans, it was much more than that.
