Nova Scotia is an old province. Some of the deed boundaries are nearly as old as the town, city or municipality in which you live and may not accurately reflect your property boundaries.
You should get a boundary retracement when buying, selling or developing any portion of your property. This includes the building of fences or out buildings.
When buying or selling property, a boundary retracement ensures that both parties know exactly where the property is situated. This is especially useful for subdivided properties which may require Right of Way access or is earmarked for future municiple development.
Boundary disputes can take place even in well-established neighborhoods. Should there ever be a dispute over property boundaries, easements or covenants restricting development of your property, you will be prepared with a current certified map of your land.
