Will your neighbour dispute your notice?
Answer six quick questions and see how likely a party wall dispute is, plus the steps that keep your costs down and your build on track.
Most party wall disputes do not come from the building work. They come from surprise, poor communication and a notice that lands without warning. The good news is that dispute risk is something you can lower before you serve. This tool shows you where you stand.
A party wall dispute is deemed to arise when a neighbour does not consent in writing within 14 days of the notice, even if they simply do not reply. Under Section 10 of the Party Wall etc. Act 1996, that triggers the appointment of surveyors and a party wall award. Good communication before serving is the single biggest factor in avoiding it.
Answer six quick questions
What a dispute really means
The word dispute sounds dramatic, but under the Party Wall Act it is a technical state, not a row. If your neighbour does not consent in writing within 14 days of your notice, a dispute is deemed to have arisen, even if they just stay silent.
When that happens, Section 10 kicks in. The parties either appoint one impartial agreed surveyor, or each side appoints their own, and a party wall award is drawn up before works start. A dispute does not stop your build. It adds a step, and it adds cost, especially if two surveyors are involved.
The numbers that matter. Your neighbour has 14 days to respond to a notice. Silence is treated as dissent under Section 10. The building owner normally pays the reasonable fees of both surveyors where two are appointed, which is why lowering dispute risk directly lowers your cost.
How to lower the risk
Almost every avoidable dispute traces back to one thing: the neighbour felt surprised or ignored. Here is what moves the needle.
Talk to them first, before any formal notice lands. Explain what the works involve and how long they will take. Serve a clear, correct notice in good time, not at the last minute. Offer a schedule of condition so they feel protected. And where you can, offer to use a single agreed surveyor, which is cheaper for you and reassuring for them. For the formal route, see our dispute resolution service.

Three situations London homeowners face
These are representative situations, not named clients, but they show how risk turns into cost.
The chat that saved the bill
An owner spoke to their neighbour weeks before serving, walked them through the loft plans, and offered a schedule of condition. The neighbour consented inside the 14 days. No award, no second surveyor. The lesson: an early, honest conversation is the cheapest dispute insurance there is.
The notice that landed cold
A basement notice arrived with no warning to a neighbour who had already clashed with the owner. They dissented at once. Two surveyors, a full award, and weeks of delay followed. The lesson: surprise plus a strained relationship plus intrusive works is the high risk recipe, and it is expensive.
The nervous neighbour who came round
A neighbour was anxious about cracks but not hostile. The owner offered a single agreed surveyor and a schedule of condition. The neighbour relaxed and the job stayed affordable. The lesson: medium risk can be steered down to consent with the right offer at the right time.
