Resolving a boundary dispute
Generally speaking there are two pathways to resolving a boundary dispute: either you resolve it yourself with your neighbour, or you seek legal help and resolve the dispute using the legal and court system.
Resolving it yourself can be stressful, frustrating and require you to "dig deep" into your reserves of patience in order to work through to a resolution with your neighbour. Going the legal route allows you to distance yourself from the direct contact of the dispute, however it can be prohibitively expensive and take many years to resolve.
The advice we give our clients is to do whatever you possible can to resolve the boundary dispute yourself with your neighbour before going the legal route, because once you commit to that, you likely need to be willing to invest heavily to get your desired outcome.
