Can a Surveyor Settle Fence Disputes in NSW?

A fence that appears to sit in the same place it has always been can still become a serious issue when a neighbour plans a build, sells their property, removes an old hedge or requests a new fence. So, can a surveyor settle fence disputes? A registered surveyor can establish where the legal boundary lies and provide reliable evidence for the parties involved. However, they do not have the authority to force an agreement, award costs or decide a legal dispute.

That distinction matters. In many cases, once the boundary is accurately marked, a practical fence disagreement becomes much easier to resolve. Where it does not, the survey information gives owners, solicitors and the relevant court a sound factual basis to work from.

What a surveyor can determine in a fence dispute

A fence is not automatically the legal boundary. It may have been built inside one property, over the line, or in a position chosen around terrain, trees, drains or an earlier informal agreement. On older Central Coast properties, fences can pre-date subdivision work, retaining walls or past building projects by decades.

A registered land surveyor investigates the cadastral boundary – the legally defined line between titles. This involves examining deposited plans, title information, survey records and physical evidence on site. Existing survey marks may be found and assessed, while measurements are taken using professional survey equipment and checked against the applicable survey information.

If the evidence supports it, the surveyor can place boundary marks or pegs to show the boundary’s location on the ground. The result is not an estimate based on a tape measure, a satellite image or the apparent alignment of nearby fences. It is a professional boundary determination made by a registered surveyor working within NSW surveying standards.

A surveyor can also identify related issues that affect a proposed fence, including easements, restrictions, road widening, irregular lot shapes or an existing structure that may cross the boundary. These issues are often missed when owners assume the fence line tells the whole story.

What a surveyor cannot do

A surveyor does not act as a mediator, judge or legal representative. They cannot require your neighbour to contribute to a new fence, order a fence to be moved or decide who is at fault. They also cannot resolve ownership arguments simply because one owner has maintained land on the other side of a fence for many years.

Under the Fences Act 1991 (NSW), questions about the type of dividing fence, notice requirements and contribution to costs are separate from the technical question of where the boundary is located. The answer may depend on the circumstances, the notices exchanged and any agreement between neighbours.

Where owners cannot agree after the boundary is established, they may need legal advice, mediation or a court process. A survey plan, field evidence and clear boundary mark-out can be valuable evidence in that process, but the final legal outcome sits outside the surveyor’s role.

Why a boundary mark-out is often the first practical step

It is tempting to begin with a quote from a fencing contractor, especially if the existing fence is leaning, damaged or missing. But replacing a fence before confirming the boundary can create an expensive problem. A new fence built in the wrong position may need to be removed, even if both parties believed they were doing the right thing at the time.

A cadastral boundary mark-out removes guesswork before construction starts. It helps each owner see the line on the ground and allows a fencing contractor to price and build against a known reference. It can also protect building plans where a garage, pool, deck, retaining wall or extension is close to the boundary.

The survey may show that the existing fence is already correctly located. That is useful too. It gives both parties confidence to proceed with replacement works and reduces the risk of a disagreement resurfacing later.

Can an identification survey help?

An identification survey and a boundary mark-out serve different purposes, although both involve cadastral investigation. An identification survey is commonly used for property transactions, building certificates and waterfront licence transfers. It identifies the relationship between visible improvements and title boundaries, and may reveal whether structures appear to encroach or whether other title issues need attention.

For a live fencing issue, a boundary mark-out is usually the more direct service because it focuses on locating and marking the boundary for use on site. The right scope depends on the purpose. If you are buying, selling or seeking a council certificate as well as dealing with a fence, an identification survey may be appropriate. If you need to know where to build a new dividing fence, a boundary mark-out may be the efficient starting point.

A registered surveyor can assess the title, site conditions and intended works before recommending the scope. This avoids paying for a report that does not answer the question you actually need resolved.

A sensible process when the fence line is disputed

Start by keeping communication with your neighbour factual and calm. Avoid moving a fence, removing old posts or relying on verbal assumptions while the location is uncertain. Even a well-intended repair can be interpreted as an attempt to take control of disputed land.

Next, arrange for a registered surveyor to investigate and mark the boundary. Provide any plans, correspondence, older survey documents or information about previous works that may assist. The surveyor will still rely on authoritative records and field evidence, but background information can help explain what is found on site.

Once the boundary is marked, discuss the practical outcome. The existing fence may stay where it is by agreement, be rebuilt on the boundary, or require a different solution because of a wall, tree, services or difficult access. Put any agreement about fence position, design and cost in writing. If the issue remains unresolved, obtain legal advice before undertaking work that could affect the other owner’s land.

When the issue is more than a fence dispute

Sometimes a fence disagreement points to a broader property issue. A shed, garage, retaining wall, driveway, pool fence or building addition may be close to, or across, the boundary. In other cases, an easement runs along the side boundary and limits where a fence can be installed or what access must remain available.

These situations need careful handling. Moving a fence may be straightforward, but moving a structure rarely is. An accurate survey gives architects, builders, engineers and solicitors the information needed to assess the next step before costs escalate.

This is particularly relevant on sloping or waterfront-adjacent sites, where fences may follow practical contours rather than title lines. It also matters on properties that have changed through subdivision, consolidation or redevelopment. The more complex the history and site conditions, the less reliable an assumption based on an old fence becomes.

Choosing the right surveyor in NSW

For a boundary issue, engage a surveyor registered in NSW, not simply a contractor offering measuring services. Boundary definition is specialised cadastral work with legal and technical consequences. A registered surveyor has the qualifications, competency requirements and authority to undertake this work and place survey marks where appropriate.

Ask what the proposed scope includes, whether the boundary will be marked on site, what documents will be supplied and whether difficult access, dense vegetation or missing survey marks may affect timing or cost. Clear answers at the outset help avoid delays and allow both neighbours to make informed arrangements.

Central Coast Surveyors assists property owners and project teams with cadastral boundary mark-outs and identification surveys across the region, providing clear site information that can support informed discussions before fencing or construction proceeds.

The most productive next move is rarely to argue over where the fence has stood. Establish the legal boundary first, then use that certainty to reach a practical agreement that protects both properties.
