Party Wall Case Law: The Leading Authorities Explained

Most searches for party wall case law start with a name rather than a topic. A surveyor drafting an award needs the citation for Kaye. A solicitor advising on a late appeal needs to know whether Freetown or Knight governs.

This digest sets out the leading authorities on the Party Wall etc. Act 1996, grouped by the issue they decide rather than by date. Every citation has been checked against the text of the ruling. Where a case predates neutral citations, we have relied on passages quoted verbatim in later Court of Appeal decisions and said so.

Our property litigation team acts in party wall disputes on both sides of the wall.

When is the Act engaged at all?

If the statutory machinery has not been triggered, the surveyors have no jurisdiction and the parties are left with their ordinary rights.

Power and Kyson v Shah [2023] EWCA Civ 239

The building owner carried out works without serving a section 3 notice, on advice that the Act did not apply. The adjoining owners appointed a surveyor anyway, who used the section 10(4) default procedure to appoint one for the building owner. Those two surveyors then awarded compensation.

The Court of Appeal dismissed their appeal. Coulson LJ agreed with the judge below that the position was, in short, “no party structure notice, no Act”. Lewison LJ added that an adjoining owner cannot unilaterally remove a citizen’s right of access to the courts by appointing a surveyor.

Why it matters: where no notice was served, an adjoining owner must sue, not appoint. Read the ruling.

Selby v Whitbread & Co [1917] 1 KB 736

McCardie J held that the London Building Act 1894 was “not an addition to but in substitution for the common law with respect to matters which fall within the Act”, describing it as a governing and exhaustive code. He preserved a damages claim where a building owner exercises statutory privileges through negligence, improper obstructiveness, avoidable nuisance or unreasonable delay.

Why it matters: the origin of the substitution principle. Quoted verbatim at paragraphs 69 to 72 of Power and Kyson v Shah.

Standard Bank of British South America v Stokes (1878) 9 Ch D 68

Jessel MR held that a building owner’s rights under the party wall legislation were “exclusive, and he has no other rights”, and that he may not begin work until the surveyors have determined the time and manner of doing it.

Why it matters: the earliest clear statement that the statutory scheme displaces common law rights in a party structure. Quoted at paragraphs 64 to 66 of Power and Kyson v Shah.

Louis v Sadiq (1997) 74 P & CR 75

Evans LJ held that the adjoining owner’s common law rights “are supplanted when the statute is invoked”, but that a building owner who commits an actionable nuisance without giving notice and without consent remains liable at common law.

Why it matters: the mirror image of Selby. Ignore the Act and you keep full exposure in nuisance. Quoted at paragraph 77 of Power and Kyson v Shah.

Woodhouse v Consolidated Property Corporation Ltd (1993) 66 P & CR 234

Glidewell LJ held that the dispute resolution provisions of the 1939 Act related only to differences about whether permitted works could be carried out and on what terms. The machinery was tied to the party structure notice.

Why it matters: it anchors the modern jurisdictional analysis. Quoted at paragraph 75 of Power and Kyson v Shah.

Rashid v Sharif [2014] EWCA Civ 377

A 225mm brick wall between two rear gardens in Ilford was held on appeal to be a party fence wall within section 20, not a wall wholly on one owner’s land. The defendants had demolished it and rebuilt it taller without serving notice. Jackson LJ held that this was a trespass, but awarded only £300 in damages in lieu of the mandatory injunction granted below.

Why it matters: the practical authority on garden walls and boundary disputes, and it confirms that a shared wall generates no adverse possession claim. Read the ruling.

Service, validity and defective notices

Once the Act is engaged, most litigation turns on paperwork.

Freetown Ltd v Assethold Ltd [2012] EWCA Civ 1657

The third surveyor posted his award. The issue was whether the fourteen day period in section 10(17), which cannot be extended, ran from posting or receipt. Rix LJ held that section 7 of the Interpretation Act 1978 applies to section 15, so a posted award is served when it would be delivered in the ordinary course of post, subject to the addressee proving otherwise.

Why it matters: it fixes the start of the appeal clock on postal service. Read the ruling.

Knight v Goulandris [2018] EWCA Civ 237

A third surveyor emailed his award as a PDF in September 2015, before the electronic service amendments took effect. No hard copy reached the adjoining owner, who appealed fifteen days later. Patten LJ held that the methods listed in section 15(1) are permissive rather than an exhaustive code, so service by another method is good where the sender proves actual receipt in legible form. The appeal was out of time.

Why it matters: email can start the clock even where the statutory list was not used. Read the ruling.

Gyle-Thompson v Wall Street (Properties) Ltd [1974] 1 WLR 123

Brightman J emphasised the importance of the procedures laid down in the London Building Acts (Amendment) Act 1939 and held that where those procedures were not correctly followed, the purported award was invalid.

Why it matters: the standard citation for the proposition that procedural defects go to validity, not merely to weight. Summarised at paragraph 74 of Power and Kyson v Shah.

Jones v Ruth [2011] EWCA Civ 804

Building works to two houses in a Nottingham terrace ran for years. A 2001 party wall notice failed to identify the works in any detail and was held invalid, and the judge found trespass and nuisance proved.

On appeal, Patten LJ held that foreseeability of injury is not an essential element of the statutory tort under the Protection from Harassment Act 1997, and awarded £28,750 and £115,000 for personal injury.

Why it matters: harassment damages sit entirely outside the Act’s compensation regime. Read the ruling.

The surveyors’ jurisdiction and its limits

Appointed surveyors exercise a statutory function, not a commercial mandate. These cases mark the edges of what an award can lawfully do.

Reeves v Blake [2009] EWCA Civ 611

An adjoining owner instructed solicitors and counsel to prepare High Court injunction proceedings, which were never issued, and the award included those costs. Etherton LJ held that the section 10 costs power is restricted to costs connected with the statutory dispute resolution mechanism. Proceedings to enforce common law or equitable remedies, and preparations for them, fall outside the Act.

Why it matters: surveyors cannot award litigation costs, nor grant relief for trespass or nuisance. Read the ruling.

Kaye v Lawrence [2010] EWHC 2678 (TCC)

Ramsey J decided the extent of the security power in section 12(1), noting there appeared to be no earlier reported decisions on it. He held that a building owner excavating within three or six metres of the boundary under sections 6(1) and 6(2) is exercising rights conferred by the Act, so security can be requested. The works need not be on the adjoining owner’s land.

Why it matters: the authority cited whenever a bond is requested. Read the ruling.

Patel v Peters [2014] EWCA Civ 335

The building owners’ surveyor declined to review timesheets supporting the other surveyor’s fees, gave reasons and proposed an alternative basis of assessment. The other surveyor treated that as a refusal or neglect to act effectively and issued fee awards ex parte under section 10(6) and (7). Richards LJ held that setting out a reasoned position “came nowhere near” refusal or neglect, and quashed the awards.

Why it matters: the ex parte power is narrow. Disagreement is not neglect. Read the ruling.

Gray v Elite Town Management [2016] EWCA Civ 1318

The county court reduced an appointed surveyor’s recoverable fees by two thirds, finding she had largely done what her appointing owner told her rather than exercising her own independent skill. Jackson LJ called that “an entirely proper approach” and refused permission to appeal on the party wall grounds, no point of principle arising.

Why it matters: endorsement of fee reduction where a surveyor fails to act independently, relevant to any surveyor negligence or fee challenge. Read the ruling.

Appeals and enforcement

Zissis v Lukomski [2006] EWCA Civ 341

An addendum award was issued without a third surveyor being selected, and the claimant challenged it by CPR Part 8 claim. Sir Peter Gibson held that a section 10(17) appeal is governed by CPR Part 52 and proceeds by way of rehearing, with the county court receiving evidence because an award is non-speaking and made without a hearing. A party may also claim within Part 52 proceedings that the award is a nullity, or seek declaratory relief instead.

On enforcement, Brooke LJ held that the Act makes no award enforceable as if it were a court order, so CPR 70.5 is unavailable. Section 17 makes sums recoverable summarily as a civil debt.

Why it matters: the procedural map for every appeal and every enforcement step. Read the ruling.

Damages and the common law overlap

Lea Valley Developments Ltd v Derbyshire [2017] EWHC 1353 (TCC)

Notifiable excavation works damaged a neighbouring block of flats. The developer sought a declaration that compensation under section 7(2) fell to be assessed as diminution in value rather than reinstatement cost. Mr A Williamson QC held that common law principles for torts affecting land apply to “loss or damage”, but that either measure may be appropriate on the facts. Both declarations were refused.

Why it matters: there is no fixed measure, so awards assuming reinstatement cost as of right are vulnerable. Read the ruling.

Roadrunner Properties Ltd v Dean [2003] EWCA Civ 1816

Works were carried out to a party wall in Battersea without notice, denying the adjoining owner any pre-works survey. Chadwick LJ held that a building owner “should not be allowed to obtain a forensic advantage by his own failure to comply with the statutory requirements”, and that a court should take a reasonably robust approach to causation.

Why it matters: the causation authority where no schedule of condition exists. Read the ruling.

A case you will see cited that is not on the public record

Chaturachinda v Fairholme is often listed in surveyors’ digests as the leading decision on special foundations under section 7(4). It was decided in the Central London County Court in 2015 before His Honour Judge Bailey, carries no neutral citation, and is not published on Find Case Law.

We have not summarised its reasoning, because we could not obtain the approved transcript from an official source. If you intend to rely on it, order the transcript rather than working from a secondary summary. The section 20 definition of “special foundations” is the starting point in any event.
