Fences, online maps and property boundaries: what to verify

If your fence looks offset from the property line on an online map, start by recording where the two disagree. An aerial image shows features you can see, while the parcel overlay helps you locate a property in the map. A screenshot alone cannot establish the boundary on the ground.

Gather the records for that part of the property

Find the lot and deposited plan references on your title documents. For Torrens title land, the State Library of NSW explains how the deposited plan records property boundaries. Give the surveyor the plan and any previous survey you have. Note which section of fence is in question and whether the issue involves a corner, gate, retaining wall or structure.

Keep the map screenshot and take dated photos from a place you can lawfully access. They help explain what you are seeing. If the fence was recently moved or replaced, share what you know about the timing and provide any plans used for the work.

Explain the decision you need to make

Replacing a fence, checking a possible encroachment and planning a new building can call for different information. Tell the registered land surveyor what decision is pending. Ask what the survey will show about the position of the fence or structure relative to the boundary, and whether the scope covers marking the line on site. Share any plans or written advice the result needs to address.

If the issue is a disagreement with a neighbour, see Legal Aid NSW’s guidance on finding a boundary for fencing work. It explains the boundary notice process and when a registered surveyor can help. Seek advice on how that process applies before committing to work along a disputed line.

If you need to locate the boundary or understand where a structure sits in relation to it, read about identification surveys. If your designer needs ground levels and site features as well, see our comparison of boundary and detail surveys and include both needs in your brief.
