The Party Wall etc. Act 1996 provides a framework for managing certain building works affecting party walls, boundary structures and neighbouring buildings. It can apply when an owner plans to alter an existing party wall, build on or near a boundary or excavate close to an adjoining property. The Act applies throughout England and Wales.

Party wall issues can affect development programmes, construction costs and relationships between neighbouring owners. Disputes may concern the validity of a notice, the scope or timing of the works, access to neighbouring land, protective measures, surveyors’ fees, damage or the terms of a party wall award.

DTM Legal advises developers, commercial property owners, investors, landlords, tenants and adjoining owners on party wall matters. Our Property Litigation solicitors work closely with our Construction & Engineering team and experienced party wall surveyors to address the legal, technical and commercial issues involved.

Why Instruct DTM Legal?

Party wall disputes can involve both technical construction questions and complex points of property law. Our Property Litigation and Construction & Engineering solicitors work together to assess the notices, proposed works, surveyors’ decisions and practical risks affecting the project.

We focus on the outcome that matters to you. For a building owner, this may mean protecting the development programme and avoiding an injunction. For an adjoining owner, it may involve securing appropriate protective measures, preventing unauthorised interference or obtaining compensation for damage.

We work with party wall surveyors, structural engineers and other specialists where technical evidence is required. Our aim is to resolve disagreements proportionately, but we can act urgently where works have started without notice or an owner needs to challenge an award, seek an injunction or respond to court proceedings.

We provide:

Clear advice on the application of the Party Wall etc. Act 1996
Strategic support for building and adjoining owners
Combined property litigation and construction expertise
Detailed review of notices, awards and technical information
Coordination with party wall surveyors and engineers
Urgent advice where development work is at risk
Robust court representation where proceedings are necessary

Frequently Asked Questions

Commonly asked questions concerning party wall disputes.

The Act can apply to work on an existing party wall or party structure, including cutting into it, increasing its height, rebuilding it or removing chimney breasts. It can also apply to new walls built on or at a boundary and certain excavations near neighbouring buildings.

Not every extension or construction project falls within the Act. The proposed design, position and foundation depth should be reviewed before notices are prepared or work begins.

The Act does not contain a standalone enforcement process for failure to serve notice. However, an adjoining owner may apply to the court for an injunction to stop the work or pursue other legal remedies.

Starting without notice can also make it harder for the building owner to demonstrate the condition of the adjoining property before construction began. Building owners should obtain advice promptly rather than assuming that a notice can simply be served retrospectively.

An adjoining owner cannot necessarily prevent works that the Act lawfully permits, but they can require the statutory procedure to be followed. They may appoint a surveyor and seek appropriate protections concerning how and when the work is carried out.

The adjoining owner may also apply for an injunction where work is proceeding unlawfully or without the required notice. Issues outside the Act, including restrictive covenants, rights of way or planning restrictions, may separately affect whether the development can proceed.

The building owner will usually pay the reasonable costs of preparing the award, including the adjoining owner’s surveyor’s fees, where the works are solely for the building owner’s benefit.

Responsibility may be divided differently where the works address a shared defect or the adjoining owner requests additional work for their own benefit. The surveyor or surveyors will determine responsibility for fees and other relevant costs within the award.

Legal fees relating to injunctions, award appeals or other court proceedings are considered separately and may be dealt with under the applicable court costs rules.

Yes. A party wall award is generally final and binding unless it is rescinded or modified by the County Court. An owner normally has only 14 days from service of the award to appeal.

An appeal should not be undertaken lightly because the unsuccessful party may be ordered to pay legal costs. Immediate advice is important so that the award, the surveyors’ jurisdiction and the proposed grounds of appeal can be assessed before the deadline expires.

Tom Evans provided an excellent service regarding my recent Voluntary Redundancy. Tom was friendly, knowledgeable and helpful in supporting the processing of the legal documentation around redundancy. Tom was very timely and managed our sessions well to ensure we didn’t overrun. I would highly recommend Tom and use him again if I needed legal support.
