A pre-purchase land survey in NSW helps buyers confirm property boundaries, identify encroachments or easements, and understand any restrictions that may affect the land or future development plans. It can reveal issues such as boundary disputes, incorrect land dimensions, or structures crossing property lines before settlement.

The two most common surveys are:

1. Identification (Boundary) Survey – confirms boundaries, structures, easements, and encroachments.
   
   
2. Contour and Detail Survey – shows land levels, drainage, and site features to assist with future building or renovation plans.
   
   

Obtaining a survey before purchase can help avoid unexpected legal disputes, compliance issues, and costly rectification works after buying the property.
