Boundary marking is a surveying operation that serves to permanently establish the boundaries of one or more properties. During this procedure, the owners of the contiguous lots for which the land surveyor is to determine one or more limits must intervene. Usually, the owners choose to proceed with boundary marking in the event of a dispute.
Boundary marking can be settled out of court, meaning that there is an agreement between the neighbours regarding the position of a common boundary. If that is not the case and the owners are unable to reach an agreement concerning the common boundary, the boundary marking becomes legally binding.
