Quick Answer: Boundary discrepancies on South Australia property titles happen when physical fences, walls, or driveways don't match the boundaries recorded in official property records. These mismatches can signal encroachments, unregistered easements, or heritage restrictions that transfer to the new owner at settlement. A title search boundary review—starting with the Certificate of Title and the deposited plan—is the baseline check every buyer should complete.
Why Boundary Discrepancies Matter in South Australia
South Australia operates under the Torrens title system. In theory, the register is the definitive record of what you own. In practice, physical boundaries on the ground often drift from what's recorded. A fence might have been built in the wrong place decades ago. A driveway might cross onto a neighbour's lot. A garage might encroach on a drainage easement.
These discrepancies don't resolve at settlement. They transfer with the title. Buying a property with an existing encroachment means you inherit the risk—including potential orders to remove structures or negotiate retrospective easements at your own cost.
Common Boundary Issues on SA Titles
Torrens Title Fences and Structures
Most freehold houses in SA are Torrens title. The Certificate of Title references a deposited plan that defines the lot's exact dimensions and boundary angles. If the fence on site doesn't match that plan, you need to know why and how far the discrepancy extends. Minor fence-line variations are common, but structural encroachments—a garage built over the boundary, a retaining wall on a neighbour's lot—can require demolition or financial compensation.
Community Title Boundaries
Community titles in SA define both lot boundaries and common property. Boundary discrepancies on community titles carry extra complexity because the community corporation has obligations for shared infrastructure. A lot boundary that doesn't match the registered community plan may change your contribution to common area costs or alter your exclusive use rights.
Easements Affecting Boundaries
Easements registered on a SA title—drainage, sewer, right of carriageway—don't always have visible evidence on site. Conversely, a visible shared driveway might not be registered. Either scenario creates boundary risk. An unregistered easement may mean you cannot legally use a driveway you assumed was yours. An undisclosed easement may restrict where you can build on your own lot.
Encumbrances and Heritage Overlays
Encumbrances on SA titles can restrict boundary modifications, particularly in heritage areas. If a property sits within a state heritage area, boundary changes, fencing materials, and even paint colours may be controlled. These restrictions attach to the title, not the owner. They override what you might assume you can do with your boundaries.
Boundary Check Checklist for Buyers
Work through this checklist when reviewing a SA property title for boundary risk:
- Compare the deposited plan lot dimensions against the physical boundaries on site
- Identify all registered easements and confirm their physical location matches the plan
- Check for encumbrances that restrict boundary modifications or fencing
- Verify community title lot boundaries against the community plan and common property schedule
- Look for caveats that may signal boundary disputes or unresolved claims
- Confirm heritage overlays that control boundary structures and materials
- Cross-reference the Certificate of Title volume and folio with the current plan to ensure no boundary alterations have occurred since the last registration
- Order the specific plan or dealing if any discrepancy appears between the title description and the physical site
Document Comparison: What Reveals What
| Document | What It Shows for Boundary Checks |
|---|---|
| Certificate of Title | Lot description, registered easements, encumbrances, caveats |
| Deposited Plan | Surveyed lot dimensions, boundary angles, easement positions |
| Community Plan | Lot boundaries, common property boundaries, exclusive use areas |
| Plan / Dealing | Historical boundary changes, subdivisions, easement registrations |
When to Order a Plan or Dealing
If your title search boundary check reveals any mismatch between the registered plan and the physical site, order the specific plan or dealing referenced on the Certificate of Title. This is essential when:
- The lot description on the title refers to a plan you haven't reviewed
- An easement notation references a dealing number you need to examine
- A caveat mentions a boundary dispute or an unresolved ownership claim
- The community title references an exclusive use area that doesn't match the physical layout
A Current Title / State Lease search through TitleFinder is $74.50 AUD and provides the full title detail needed to begin this process. If the title references additional plans or dealings, these can be ordered separately once you know the reference numbers.
Quick Caveat
This article is for general information only and does not constitute legal advice. Boundary disputes and encroachments often require assessment by a licensed surveyor or legal practitioner. Verify all findings with qualified professionals before acting.
Frequently Asked Questions
How do I confirm a SA fence is on the correct boundary?
You need to compare the deposited plan dimensions—available through official property records—against a current survey of the physical site. If no recent survey exists, a licensed surveyor can establish whether the fence line matches the registered boundary. A title search boundary review tells you what the register says; a survey tells you what's on the ground.
Can a boundary discrepancy be resolved after settlement?
Yes, but resolution can be expensive. Options include boundary agreements, retrospective easements, or applications to correct the register. These processes require cooperation from affected neighbours and often involve legal and surveying fees. It is generally cheaper to identify and negotiate resolution before settlement.
Does a community title change how boundary discrepancies are handled?
Yes. Community titles introduce a corporation structure that governs common property and exclusive use areas. A boundary discrepancy on a community title may require a resolution from the community corporation in addition to any agreement with individual lot owners. Check the community plan and by-laws before assuming a boundary issue is yours alone to resolve.
