Party wall disputes are a common issue in London, particularly in areas with terraced housing, semi-detached properties, and tightly packed developments. Whether you are the building owner planning works or an adjoining owner concerned about the impact, understanding the Party Wall etc. Act 1996 is essential. The Act sets out a clear legal framework for preventing and resolving disputes relating to shared walls, boundary structures, and excavation works. At Hourican & Associates, we specialise in resolving party wall disputes in London, ensuring that projects move forward lawfully and fairly while protecting all parties involved.

What is a Party Wall Dispute?

A party wall dispute occurs when an adjoining owner does not consent to proposed works notified under the Party Wall Act. This can include:

• Extensions, loft conversions, or structural alterations affecting a shared wall
• Excavations within 3 or 6 metres of a neighbouring foundation (depending on depth)
• Chimney breast removal connected to a party wall
• Construction of new boundary walls up to or astride the property line

Disputes are not uncommon and are a normal part of the statutory procedure. If dissent occurs, surveyors are appointed to resolve matters impartially and create a binding Party Wall Award.

Step-by-Step Guide to Resolving a Party Wall Dispute

• Step 1 – Serve the Correct Notice: Notices must be valid and comply with sections 1, 3, or 6 of the Act. Incorrect notices can invalidate the process.
• Step 2 – Await Response: Adjoining owners have 14 days to consent or dissent in writing. Silence after 14 days is legally treated as dissent.
• Step 3 – Appointment of Surveyors: If there is dissent, each party appoints a surveyor, or both may agree on a single impartial Agreed Surveyor. All surveyors must act impartially under the law.
• Step 4 – Schedule of Condition: A detailed inspection records the adjoining property’s condition, ensuring both parties are protected against false claims or unproven damage.
• Step 5 – Drafting the Party Wall Award: The Award sets out the scope of works, working methods, protective measures, and responsibility for costs. It is binding on both parties.
• Step 6 – Appeal (if necessary): Either owner may appeal the Award to the County Court within 14 days, although appeals are rare and must be based on legal grounds, not personal preference.
• Step 7 – Compliance and Monitoring: The building owner must comply strictly with the Award. Breaches can lead to injunctions or claims for damages in court.

Common Causes of Party Wall Disputes

While the Party Wall Act aims to prevent disputes, disagreements often arise due to:

• Concerns about structural safety and potential damage
• Noise, dust, and disruption from proposed works
• Boundary disagreements or uncertainty over property lines
• Failure to serve valid or timely notices
• Mistrust between neighbours regarding property value impact

Our surveyors at Hourican & Associates are experienced in resolving these issues with professionalism, ensuring compliance with the law and maintaining neighbourly relations where possible.
