Handling a boundary dispute between neighbours

Boundary disputes engage multiple statutes depending on the nature of the dispute. Fence disputes fall under the Dividing Fences Act, building encroachments under the Encroachment of Buildings Act 1922, and long-standing occupation may trigger adverse possession principles.

In short

This is an 8-step workflow for handling a NSW residential boundary dispute, including fence disputes, encroachments, and adverse possession issues.

Time: 5-15 hours depending on whether a surveyor and expert evidence are needed.
Audience: NSW property lawyers acting for a residential owner in a dispute with a neighbour about a common boundary.

8 steps

The workflow

1

Gather title and survey material

Obtain title searches, the registered plan of subdivision, and any historical survey plans. Commission a current registered surveyor report where the boundary location is in doubt.

Tools: NSW LRS
2

Identify the dispute type

Identify whether the dispute is a fence dispute, a building encroachment, tree damage, easement misuse, or adverse possession claim — each has its own legal pathway.

Tools: Quillio
3

Apply the Dividing Fences Act

For dividing fence disputes, issue a Fencing Notice under the Dividing Fences Act 1991 specifying the proposed work and estimated contribution.

Tools: Quillio
Dividing Fences Act 1991 (NSW) s 11
4

Consider an encroachment application

Where a building encroaches across the boundary, consider an Encroachment of Buildings Act 1922 application to the Supreme Court for relief (removal, compensation, transfer of land).

Tools: Quillio
Encroachment of Buildings Act 1922 (NSW) s 3
5

Assess adverse possession

Assess whether the occupation is sufficiently long, exclusive and open to ground an adverse possession claim for Torrens or old system land.

Tools: Quillio
Real Property Act 1900 (NSW) Part 6A
6

Attempt neighbourhood resolution

Attempt mediation through the Community Justice Centre or direct negotiation. Document offers of settlement to preserve costs arguments.

7

Escalate to Local Court or NCAT

Escalate a dividing fences dispute to the Local Court if the notice is not agreed. Escalate other boundary disputes to the Supreme Court as appropriate.

Dividing Fences Act 1991 (NSW) s 13
8

Register final orders and update title

If the dispute is resolved by court order or deed, register any relevant plan, transfer of land, or easement with NSW LRS to update the title.

Tools: NSW LRS
Outcome

What you will have at the end

A resolved boundary dispute — either by agreement, Local Court fence orders, Supreme Court encroachment relief, or registered plan adjustment.

Common issues

  • Relying on a visual inspection rather than a registered surveyor report
  • Missing the Dividing Fences Act notice requirements
  • Overlooking the discretionary nature of Encroachment of Buildings Act relief
  • Not considering adverse possession where appropriate
  • Failing to register the final outcome on title
