A party wall is a term used to describe a wall, partition, or barrier that separates buildings or units of property owned by different individuals. It can be a wall that is part of one building or divides two separate buildings and can also include garden walls built over a boundary, known as party fence walls. Under the Party Wall Act 1996, the term is expanded to cover a variety of circumstances and includes additional structures such as floors and ceilings between flats, and shared garden walls. The Act provides a framework for preventing and resolving disputes in relation to party walls, boundary walls, and excavations near neighbouring buildings.
When planning construction work that impacts a shared wall or boundary, UK law mandates serving a Party Wall Notice to adjoining owners under the Party Wall Act 1996. This legal formality aims to inform neighbours of intended works that may affect their property and offers them a chance to agree or raise concerns. However, the process, while protective, is not devoid of risks which are essential to understand for anyone contemplating or undergoing construction works. In this blog, we take a look into the risks that may come with serving a Party Wall Notice.
Legal Disputes
One of the most common risks of serving a Party Wall Notice is the potential for legal disputes. If the notice is not served correctly, or the information provided is insufficient or inaccurate, adjoining owners may dispute the validity of the notice. This can lead to delays, legal challenges, and potentially increased costs due to legal fees and disruptions in the construction timeline
Delay in Project Commencement
Timing is everything when serving notices. The Party Wall Act requires notices to be served at specific times before the works commence, usually one to two months depending on the type of notice. Failure to comply with these timing requirements can invalidate the notice and delay the start of the project, affecting project scheduling and budgeting.
Financial Implications
The process of dealing with a party wall can incur costs that may not be initially anticipated. If an adjoining owner dissents to the notice, both parties might need to appoint surveyors to draft a Party Wall Award, which outlines how the works should proceed. This can lead to additional costs for hiring surveyors and potentially for making adjustments to the project plans to comply with the terms of the Party Wall Award.
Damage to Relationships with Neighbours
The act of serving a Party Wall Notice can sometimes strain relationships between neighbours, particularly if one party feels that the construction work will negatively impact their property. This can lead to long term discomfort in neighbourly relations, which might be more disadvantageous than any legal or financial issue.
Risk of Damage Claims
Even with a Party Wall Agreement in place, there is always a risk that construction work might cause damage to adjoining properties. If such damage occurs, the building owner may face claims from neighbours. Although a Schedule of Condition, a report detailing the pre-work condition of the adjoining property, can help mitigate this risk by providing a clear baseline for any claims of damage, the risk cannot be entirely eliminated.
Reducing the Risks
The risks associated with serving a Party Wall Notice can be mitigated by ensuring the notice is comprehensive and served in a timely and correct manner. It is advisable to engage the services of experienced Party Wall Surveyors who can manage the process efficiently, ensuring compliance with legal requirements and helping to maintain good relationships with neighbours.
