Who owns the fence? What the law actually says
Last updated: 16 August 2026
Almost everything you've been told about this is folklore. The posts face your side, so it's yours. The left-hand one is always yours. There's a T-mark, so that settles it. HM Land Registry has published, in plain terms, that there is no legal foundation for these beliefs — and it's worth knowing why before you spend money on a fence that may not be yours to touch.
The rules that aren't rules
Start with the clearest statement anyone official has made about this. HM Land Registry's practice guidance on boundaries says:
"There are various notions that the way a wall or fence is constructed indicates ownership, for example that the posts and arris rails of a fence are on the owner's side. There is, however, no legal foundation for such beliefs."
And on the version most people have heard — that the left-hand boundary as you look from the road is yours — Land Registry is equally direct: "there isn't any legal basis for this."
So, to be explicit, none of the following decides ownership:
- Which side the posts and arris rails face.
- Which side the smooth or "good" side faces.
- Whether it's the left-hand or right-hand boundary.
- Who built it, or who last repaired it.
- Any alternating pattern down a street, or a developer's habit on an estate.
- Where the fence physically stands — a fence line is not automatically the legal boundary.
These beliefs are common because they're often locally true — builders did tend to work a certain way. But a habit isn't a rule, and a surveyor won't accept one.
What a title plan actually shows
Under the Land Registration Act 2002, a registered boundary is a general boundary, and the Act says it directly: "A general boundary does not determine the exact line of the boundary."
That red line on your title plan shows the general position of the boundary. It isn't drawn to a legal tolerance, it doesn't tell you which side of a fence the line runs, and it does not say who owns the fence. Land Registry is clear that there is usually no record at all of who owns the hedge, wall, tree or fence between two properties — that information appears on the register only where the deeds lodged at the time specifically referred to it.
So what about T-marks?
A T-mark is a small "T" drawn on a plan against a boundary, with the stem on one side. It is widely treated as decisive. It isn't — on its own.
Land Registry's position is that T-marks on deed plans which are not referred to in the text of a deed have no special force or meaning in law, and that it will normally ignore them unless specifically asked to show them. Where a T-mark does carry weight, it's because a clause in the deed says something like "the Transferee shall maintain the boundaries marked T on the plan". The obligation lives in that wording, not in the mark.
Which leads to the most useful thing on this page: a covenant to maintain a boundary does not make you its owner. Responsibility and ownership are different questions, and a deed can answer one without touching the other.
The presumptions that are real law
A few genuine legal presumptions do exist. They're narrower than people hope, and — this is the part that matters — they resolve where the line runs, not who owns the thing standing on it.
| Presumption | What it does |
|---|---|
| Hedge and ditch | Where a hedge sits beside an artificial ditch, the boundary is presumed to run along the far edge of the ditch from the hedge. The ditch must be man-made. |
| Ad medium filum | For a road or a non-tidal watercourse, ownership is presumed up to the mid-line. |
| Projections | Eaves and foundations belong with the building they serve, not with the airspace or ground between. |
All three are rebuttable — evidence can displace them. None of them tells you whose fence it is.
Is anyone obliged to repair it?
This is where most pages on this subject state something confident, and we're not going to. The honest answer is that any duty to maintain a boundary feature comes from the deeds — a covenant, imposed at some point in the property's history and recorded in the documents. If there's no such covenant, there may be nothing obliging anyone to do anything.
What we won't tell you is that there is definitively no duty, whether an old covenant still binds a later owner, or that you can make a neighbour repair a fence or recover the cost from them. Those are questions about your specific deeds and their history, and they're exactly what a conveyancer reads documents to answer. Anyone giving you a flat answer to them without seeing your title is guessing.
Where the Party Wall Act comes in — and where it stops
A party fence wall is a real thing under the Party Wall etc. Act 1996, and our whole site is about that Act — so it's worth being precise about its limits here.
- The Act reaches a masonry wall standing astride the boundary. Work on one can need a notice.
- It does not reach a wooden fence or a hedge, whichever side of the line it stands on.
- And it does not decide title. Land Registry puts it plainly: "In general terms the Act does not affect ownership of land."
So the Act can tell you whether you owe your neighbour a notice before working on a shared masonry wall. It cannot tell you whose fence it is. What is a party wall? covers the definitions, and if you're planning a new masonry boundary wall, that's a section 1 question rather than a fence-ownership one.
How to actually find out
In order, cheapest first:
- Get both title registers and plans from HM Land Registry — yours and next door's. They're a few pounds each and available to anyone.
- Read the register for a boundary clause. You're looking for wording about maintaining or fencing a particular boundary, often referring to marks on a plan. Most registers have nothing.
- Ask for the pre-registration deeds. The detail, if it exists anywhere, is usually in the original transfer or conveyance rather than the register.
- Take it to a conveyancer if the documents are ambiguous or the stakes are real. This is document interpretation, and it's what they do.
- If you need certainty, there are two formal routes — see below.
And in the meantime: change nothing. Removing or replacing a boundary feature you can't prove is yours is how a disagreement becomes a dispute.
The two routes to certainty
A boundary agreement is the practical one. You and your neighbour agree where the line runs — and it can also record who's responsible for maintaining a hedge, wall, tree or fence. It can be noted on the register (form AP1, £40 at the time of writing). What it cannot do is move a boundary or transfer land.
A determined boundary is the formal one: form DB, a plan from a chartered land surveyor, and evidence, at £90 at the time of writing. If your neighbour objects and it can't be resolved, it goes to the First-tier Tribunal (Property Chamber, Land Registration division). It fixes the exact line — and only the line. It does not settle who owns or maintains the fence.
Fees are the published GOV.UK figures at the time of writing — check the current ones before you apply.
The short version
There is no rule about posts, sides or T-marks. Your title plan shows a general boundary and usually says nothing about the fence. Any duty to maintain comes from the deeds, if it exists at all. And if you can't establish that a fence is yours, treat it as shared and agree before you touch it — which is Land Registry's own advice, and considerably cheaper than the alternative.
