The short answer
There is a common assumption that whoever owns a boundary fence or wall must keep it in repair. In fact, ownership alone does not create a legal duty to maintain. Generally, you can let your own boundary fence fall into disrepair without breaching any obligation — unless the deeds impose a maintenance covenant, or another rule applies: a wall that provides support to a neighbour’s land or building (a retaining wall) can carry duties; a dangerous structure can bring safety obligations; and a wall that is a party wall or party fence wall is governed by the Party Wall etc. Act. So responsibility depends on the evidence in the deeds and the nature of the structure, not simply on who owns it.
Why it matters
Knowing who owns a fence is a different question from who, if anyone, must maintain it. The deeds may expressly allocate a maintenance obligation — that is the most common source of a duty — so they are the first place to look. Absent that, an owner is often free to leave a simple boundary fence unrepaired, which surprises neighbours who expect it to be kept up. The important exceptions are walls that hold back soil or give support (where removing or neglecting them can cause real liability), structures that have become dangerous, and party walls and party fence walls, which sit under a separate statutory regime. As with ownership itself, the answer is found in the documents and the facts, not in assumption.
What to do now
- Check the deeds for any maintenance or repair covenant.
- Establish ownership first — then ask separately whether a duty to maintain exists.
- Treat retaining walls and any dangerous structure as special cases needing advice.
- For a shared wall, check whether the Party Wall Act applies.
Common mistakes
- Assuming the owner must always repair the fence.
- Confusing ownership with a duty to maintain.
- Overlooking a maintenance covenant in the deeds.
- Treating a retaining or shared wall like an ordinary fence.
When to call Coburns
We establish ownership and check the deeds objectively, so responsibility for a boundary fence or wall is clear — and flag where a retaining wall or party wall changes the picture.
