Fences, Property Lines, and Property Encroachment
Fences shape the appearance of a garden, improve privacy, and help define property lines. They also become a very quick source of tension when they are not installed correctly. Property encroachment is a common reason for neighbourly disputes, and many problems only appear years later when a fence replacement, a house sale, or a new neighbour brings greater attention to the accuracy of the property lines.
This blog explains how encroachment happens, why property lines are so important, and how to avoid costly complications in the future.
What Is Property Encroachment
Property encroachment occurs when a structure crosses the legal property line and enters neighbouring land. Fences are often involved because many people assume that an existing fence is correctly positioned, even when no one has checked the actual property lines for years. Encroachment can affect garden use, property value, and relationships between neighbours.
- a fence placed a few centimetres inside or outside the real property line
- a retaining wall that extends into the neighbouring garden
- trees or shrubs that grow over the property line and cause disruption
- garden buildings that unintentionally cross the boundary
A fence that lies slightly across the property line may go unnoticed for a long time. However, a relaxed neighbour today may sell their home in the future, and the next homeowner may be far more careful about protecting their property lines. What appears insignificant now can become a major obstacle later.
Why Fence Encroachment Happens
Encroachment usually comes from misunderstandings or inherited mistakes. Many older fences were installed without checking the property lines against official documents. These errors then pass from one owner to another.
Property deeds contribute to this confusion. Some deeds show precise measurements that define the property lines clearly, while others include only a simple outline with no exact dimensions. When documentation varies, it is very easy for property lines to be misjudged, especially if someone relies on existing garden features instead of official records.
- assumptions based on hedges or old posts that are not aligned with the property lines
- garden layouts that gradually change and distort the perceived boundary
- forgotten informal agreements between past neighbours
- unclear communication during planning or installation
Always speak with your next door neighbour before any work begins. We have seen many situations where a property owner installs a fence without discussing the plans with the neighbour, and the only information available to the property owner is a simple boundary outline in their deeds. Once the fence is in place, the neighbour then presents deeds that provide detailed measurements of every part of the garden, the boundaries, and the original markers. This means the fence must be moved.
In several cases, the property owner had no idea that the next door neighbour held far more comprehensive documentation relating not only to their own garden, but also to neighbouring properties along the street. Deeds and other documents can be misplaced as properties change ownership, so it is always best to talk to your neighbour first and confirm everything before proceeding.
The Influence of Fence Design on Property Line Placement
The design of the fence itself also plays an important role in how close it can sit to the property line. Different construction styles have different physical footprints, which affect where the posts, rails, and boards can be positioned without crossing the boundary.
Some fences use larger posts with the boards fixed to the front face, such as kit form featherboard. In these designs, the posts sit on the boundary side of the fence, and the horizontal rails and boards are fixed to the inner face. This means the structure naturally extends further into the property than many people expect. Because of this, these fences often need to sit slightly further inside the property line to prevent any part of the structure from crossing into neighbouring land.
By contrast, fences with slotted posts and prefabricated panels have a more central installation line. The panel fits into the middle of the post, so the post footprint is shared evenly on both sides. This makes it easier to place the fence very close to the property line without risking encroachment.
Understanding the design style before installation is essential. A fence that looks narrow in a brochure may occupy far more space once installed, especially when thicker posts or deeper rails are used. Careful planning ensures that the fence design stays correctly positioned relative to the property line and avoids future dispute.
Preventing Fence Encroachment
A well planned approach protects property lines, prevents disputes, and provides long term clarity.
1. Confirm the Legal Property Lines
Check the title plan or deed plan before any work begins. Some documents provide exact measurements of the property lines, while others do not. When accuracy matters, a professional survey offers certainty and removes guesswork.
2. Communicate With Neighbours
A friendly conversation about the property lines helps reduce misunderstandings. Sharing drawings or measurements builds trust and ensures both parties understand the intended fence position. This can sometimes be difficult but is worth the effort up front in the long run.
3. Use Professional Installers
Professional fencing contractors understand boundary regulations and the importance of accurate property lines. Their experience helps identify potential issues and ensures that the fence follows the correct line. Look for installers that are vetted by larger installers and have good reviews.
4. Keep Records
Store copies of surveys, photographs, drawings, and invoices. Clear documentation supports you if questions arise later, especially during a future house sale.
5. Take Photos and Measurements Before Replacing a Fence
If you are replacing an old fence, take clear photos showing its position relative to permanent features. Measure distances to fixed points so you can compare them with the property lines shown on deeds or surveys. When installing the new fence, either match the exact line or move it very slightly into your own garden to ensure full compliance with the property lines. A small inward adjustment can prevent future disagreements, especially when the original fence was installed without proper checks.
What To Do If Encroachment Is Discovered
1. Review All Documentation
Look at title plans, deeds, and any available surveys. Compare these details with the fence position and discuss the findings with your neighbour. Many problems come from misunderstandings rather than deliberate encroachment.
2. Seek Professional Guidance
If you cannot agree on the property lines, a chartered surveyor or property solicitor can provide an independent assessment based on factual information.
3. Agree on a Practical Solution
Solutions may include repositioning the fence, formalising the property lines through an agreement, or granting a licence for the affected area. Cooperation usually leads to a long lasting resolution.
Considerations for the Future
Accurate property lines are crucial when selling a house. Even a fence that sits a few inches across the property line can delay a sale. There would be nothing worse than a misplaced fence holding up an entire property chain while surveys, reports, and indemnity insurances are arranged. These delays add stress, time, and unexpected cost to an already demanding process.
Protecting your property lines is therefore both a present and future investment. A small amount of care during installation prevents extensive complications many years later and ensures that any future sale is smooth and straightforward.
