What Counts as Encroachment
Encroachment in South African property law occurs when a neighbouring owner places a permanent structure — a wall, fence, building, or other improvement — on your property without your consent. It can also refer to trees or roots that extend across the boundary in a way that causes damage. Encroachment is a specific legal concept with established remedies, and it is distinct from minor trespass or nuisance.
Step 1 — Establish the Boundary
Before any dispute can be resolved, the exact boundary must be established with legal certainty. Boundaries in South Africa are defined by registered survey data held in the Deeds Office and Surveyor-General records. The boundary as described in the title deed and survey diagram is the legal boundary — not where a fence has historically stood or where both parties have informally assumed it to be.
If you believe there is an encroachment but are not certain where the legal boundary falls, appoint a registered land surveyor to locate and mark the boundary. A survey costs R5,000 to R20,000 depending on the complexity and the suburb, but it is the only authoritative basis for any dispute. Without a survey, any discussion about encroachment is arguing about assumptions.
Step 2 — Raise It Directly and in Writing
Once you have survey confirmation of the encroachment, approach the neighbour directly and in writing. Be factual, not accusatory — the encroachment may be entirely unintentional (they may not know where the boundary is either). Provide the survey data and a clear statement of what encroaches and by how much.
Many boundary disputes are resolved at this stage through mutual agreement: the encroaching structure is removed or relocated, or a boundary adjustment agreement is reached. Any boundary adjustment must be formally registered at the Deeds Office to be legally binding.
Legal Remedies for Encroachment
If the neighbour refuses to acknowledge or remove the encroachment, South African law provides several remedies:
- Rei vindicatio — an action to recover property being used by another without consent. In an encroachment context, this is used to compel the removal of the encroaching structure.
- Mandament van spolie — an urgent interdict to restore possession where possession has been unlawfully disturbed. Used where an encroachment is newly placed and you want it removed urgently before it becomes established.
- Court discretion to award compensation in lieu of removal — in some cases, a court may refuse to order removal (particularly where the cost of removal is disproportionate to the area encroached upon) and instead award the encroached owner compensation for the loss of the land used. This is not the encroaching owner's right to invoke — it is the court's discretion.
Trees and Vegetation
South African common law gives you the right to cut branches and roots that encroach over your boundary — but only to the boundary line, and after giving the neighbour notice. You may not cut on their side of the boundary. If the tree is a protected species under the National Environmental Management: Biodiversity Act or your municipality's by-laws, you may need permission before cutting.
If an encroaching tree causes damage to your property (root damage to foundations, falling branches damaging a roof), you can claim damages from the tree owner. The neighbour is liable for damage from their tree if they were aware of the risk and did not take action.
When to Involve an Attorney
Involve an attorney from the outset if: the encroachment involves a significant structure (a wall, a building, a swimming pool); the neighbour is unresponsive or hostile; you need to act urgently (a structure is being built over your boundary right now); or the financial value of the encroached land is significant.
An attorney's letter following the survey report often produces resolution without litigation. If litigation is necessary, the legal costs can be substantial — weigh the cost of litigation against the value of the encroached land and the cost of removal.
