Neighbour Ignores a Party Wall Notice – What Happens?
If you’re planning to carry out work on or near a shared boundary and your neighbour ignores a Party Wall Notice, it can feel frustrating and uncertain. However, the Party Wall etc. Act 1996 lays out clear legal procedures for what happens next.
This article provides a step-by-step guide to what to do if your neighbour fails to respond to your Party Wall Notice - and how to keep your project legally on track.
What is a Party Wall Notice?
A Party Wall Notice is a formal notification served by a building owner to an adjoining owner (typically a neighbour), informing them of proposed works that fall under the scope of the Party Wall etc. Act 1996. This includes:
- Building on or at the line of junction (boundary line)
- Altering, repairing, or demolishing a party wall or structure
- Excavating within three or six metres of neighbouring foundations, depending on depth
A valid notice gives the neighbour 14 days to either:
- Consent to the works,
- Dissent and appoint a surveyor, or
- Do nothing.
It’s the third option - silence - that triggers a specific legal consequence.
What Happens If a Neighbour Ignores a Party Wall Notice?
1. A Dispute is Automatically Deemed to Have Arisen
Under Section 5 of the Party Wall etc. Act 1996, if an adjoining owner does not reply to a Party Wall Notice within 14 days, the law considers this a deemed dissent. This automatically triggers a dispute, even if the neighbour has not formally objected.
This is not a dead end - it actually sets in motion the dispute resolution process.
"If an owner on whom a party structure notice or a counter notice has been served does not serve a notice indicating his consent [...] he shall be deemed to have dissented from the notice and a dispute shall be deemed to have arisen between the parties."
Section 5, Party Wall etc. Act 1996
2. A Surveyor Must Be Appointed
Once a dispute is deemed to have arisen, both parties are required to appoint a surveyor under Section 10 of the Act.
- If the neighbour fails to appoint a surveyor within 10 days of being requested to do so, the building owner can appoint one on their behalf.
- Alternatively, both parties may agree to use a single ‘agreed surveyor’ instead of each appointing their own.
This mechanism ensures that a neighbour cannot delay or obstruct works indefinitely by simply ignoring the notice.
3. A Party Wall Award is Made
Once surveyors are appointed, they prepare a Party Wall Award. This legally binding document sets out:
- The work to be done
- How and when it will be carried out
- Access arrangements
- Who pays what costs (usually the building owner)
- Provisions for protection and damage repair
The award protects both parties - ensuring the building owner can proceed, and the neighbour has safeguards in place.
4. Work Can Proceed Once the Award is Served
After the Party Wall Award is agreed and served, the building owner may legally begin the notifiable works, provided:
- The notice period has elapsed (typically one month or two months, depending on the type of work), and
- There is no appeal made to the county court within 14 days of the award being served.
Even if the neighbour remains silent throughout, they are still bound by the award.

Common Misunderstandings
“If they don’t respond, I can go ahead anyway.”
No - the lack of a response is not a green light. It results in a deemed dispute, which requires formal resolution through the appointment of surveyors and the issuance of a Party Wall Award.
“They can block the work by ignoring me.”
Also false. The Act is structured to prevent obstruction through silence. If the adjoining owner fails to respond or appoint a surveyor, you can do it for them - and progress the award regardless.
Why Silence Doesn’t Stop You - But the Process Must Be Followed
The key principle of the Act is balance. It grants the building owner legal rights to undertake works, but also gives the adjoining owner protections. If a neighbour chooses not to engage, that doesn’t invalidate the process - it just means their opportunity to input is lost.
However, skipping formal steps because a neighbour ignores you is risky. You must:
- Ensure valid service of the notice
- Wait the statutory response period
- Appoint surveyors properly
- Wait for the Award to be served and the appeal period to expire
Failing to do so can expose you to legal challenge, injunctions, or claims for trespass and damage.
What If the Neighbour Can’t Be Found?
If you're unable to locate the adjoining owner, you can serve the notice addressed to “The Owner” and fix it to a conspicuous part of the premises, as allowed under Section 15 of the Act. This ensures the legal process can still proceed even if the neighbour is absent.
What Happens If the Neighbour Appeals?
An adjoining owner has 14 days after being served with the Party Wall Award to appeal it in the County Court. Grounds for appeal are limited and usually relate to procedural flaws or unreasonable terms. If no appeal is made, the award becomes final and binding.
What Are the Consequences of Skipping the Process?
Attempting to begin work without following the Party Wall Act procedure - even if the neighbour ignores your notice - can lead to:
- An injunction stopping your work
- A claim for trespass
- Liability for damage without any protection
- Court orders to undo the works
- Significantly increased legal costs
Do You Still Need a Party Wall Surveyor?
Yes - once the neighbour fails to respond and a dispute is deemed to exist, you cannot proceed unilaterally.
A surveyor must be appointed (either mutually or separately) and an award made. Trying to proceed without one can expose you to enforcement and litigation.
FAQs: Neighbour Ignores a Party Wall Notice
What happens if my neighbour ignores the Party Wall Notice?
After 14 days, a dispute is deemed to have arisen, and you must appoint a surveyor to resolve it under Section 10 of the Act.
Can I appoint a surveyor for them?
Yes. If they fail to appoint a surveyor within 10 days of being requested to, you may appoint one on their behalf.
Do I need to stop work while I wait?
Yes. You must not begin notifiable works until the surveyors have issued a Party Wall Award and the appeal period has passed.
Can my neighbour block the work by ignoring the notice?
No. Their silence triggers a default legal process - it doesn’t give them veto power.
Can I serve notice again if I made a mistake?
Yes - if a notice was not validly served (e.g. missing information or wrong address), you can serve a corrected notice and restart the clock.
What if they come back after ignoring the notice?
They are still bound by the award and cannot prevent works once the process has been lawfully completed.
