What If the Boundary Line Runs Directly Down the Middle of the Garden Wall?
A wall standing on the boundary and separating only open land is a party fence wall under the Act, and it can be treated much like a party wall. The Act does not decide who owns what. Where the boundary runs down the middle, both owners have an interest, so agree before building or rebuilding.
Party fence walls in brief
A party fence wall stands astride the line of junction and separates open land, not buildings. Garden walls are the usual example. Ordinary timber fences are not party fence walls under the Act.
Work to these walls is covered by Section 1 and Section 2, but in a limited way. Check with a surveyor which rights apply to your wall.
What the Act does and does not decide
The Act sets out procedure for work: notices, surveyors and awards. It does not settle disputed ownership or where the boundary lies. Those questions belong to property law, and title plans are often general rather than exact.
If the two of you disagree about the line, get legal advice or use mediation before spending money on a wall.
Typical situations
- Repairing or rebuilding a wall that sits centrally on the line: work to an existing party structure, so notice may be needed
- Building a new wall wholly on your own land: this may not need notice for the wall itself, but excavation may
- Building a new wall astride the boundary: notice for a wall on the line of junction is at least 1 month
Practical steps
Look at title deeds, the land registry plan and any T marks. Talk to the neighbour early and in writing. If cost is shared, agree in writing who pays what. Nobody can be forced to pay for half a new wall simply because you want one, though the Act allows some cost sharing where work benefits both.
If the wall is unsafe, take advice quickly, because the owner may have liability if it falls.
When to instruct a surveyor
If the wall carries a building, retains soil or is high, involve a party wall surveyor and probably an engineer. Small low walls may need less, but do not assume.
Frequently asked questions
Who owns a wall on the boundary?
It depends on the deeds and the facts. The Act does not decide ownership.
Is a timber fence covered?
No, not as a party fence wall. Common law and any deed covenants apply instead.
Can I demolish half of it?
Not without considering the other owner's rights. Take advice and serve any notice needed first.
