Sometimes, but not always a boundary dispute will arise when one party constructs a fence, wall or building in a position which highlights that the two neighbours have different views as to where the boundary lies. A good place to start would be the Boundary Disputes Protocol, a non-binding pre-action protocol developed by a number of leading practitioners in the field.
