Conveyancing Advice on Missing Completion Certificates: Informed Client Instruction Defeats Breach, and “Scope of Duty” Limits Loss to the Certification Risk

1. Introduction

In Karen Lamb against Thomas Ross Bennett, George Ewan Moffat And Kenneth James Haward Soper as the partners of the firm of Campbell Boath, Solicitors and as individuals ([2026] CSOH 16), Lady Tait (Outer House, Court of Session) considered a professional negligence claim arising out of a conveyancing transaction involving a commercial unit forming part of a larger residential development in Dundee.

The pursuer (Ms Lamb), a beauty-industry businesswoman, purchased a ground-floor shop at 108 Seagate, Dundee in August 2012 using bank funding. The defenders were her solicitors (a partnership), and they also acted for the lender, Bank of Scotland/Lloyds TSB.

A key feature of the transaction was that, at settlement, the development was not complete and no local authority acceptance of a completion certificate for the wider development would be available. Missives initially sought production of “all necessary certificates of completion” (clause 17.3), but the seller’s solicitors’ qualified acceptance deleted the clause and stated no further certificates would be delivered or exhibited.

Ms Lamb later claimed that defective construction prevented her from occupying and trading from the premises, and she sued her former solicitors for very substantial loss of profits and inconvenience.

Key issues

  • Breach: whether the solicitor adequately advised about the deletion of the completion-certificate protection and the risks of settling without it, and whether the client nonetheless gave clear and informed instructions to proceed.
  • Causation / scope of duty: even if there was breach, whether the claimed losses were within the scope of the duty the solicitor owed—i.e., whether the losses were the “fruition of the risk” the relevant duty was meant to guard against.
  • Quantum: whether the business-plan-based loss of profits case was proved and sufficiently reliable.

2. Summary of the Judgment

Lady Tait granted decree of absolvitor (dismissal) in favour of the defenders.

  • No breach to the pursuer: the court preferred the evidence of the solicitor, Mr Soper, and found the pursuer had been advised of the absence of the completion certificate and the implications, and nevertheless gave clear and informed instructions to proceed without insisting on alternative contractual protection.
  • Scope of duty / causation (obiter/hypothetical): even if there had been breach, the pursuer’s losses flowed from defective building work requiring remedial works, not from the temporary absence/delay of an accepted completion certificate. Therefore the losses claimed did not fall within the scope of the duty said to be breached.
  • Quantum (hypothetical): the loss of profits case, grounded on the pursuer’s business plan, was held speculative and overly ambitious; and the inconvenience claim, if it arose, would have been modest (Lady Tait indicated not to exceed £5,000, rather than the £60,000 sought).
  • Duty to the bank: the court recorded that the defenders were in breach of their duty to the bank by drawing down funds without telling the bank the promised undertaking would not be forthcoming, but that did not found the pursuer’s case.

3. Analysis

3.1 Precedents Cited

Hunter v Hanley (1955 SC 200)

The judgment uses Hunter v Hanley as the familiar Scottish benchmark for professional negligence: whether the professional acted in a way “which no solicitor of ordinary skill acting with ordinary care would have followed” (the judgment adopts this formulation through the skilled witness evidence).

Its influence here was principally to frame the standard-of-care discussion about whether it was professionally acceptable to settle without an accepted completion certificate, and whether alternative protections (e.g., an undertaking/retention) were necessary absent informed client instruction. Notably, the court ultimately decided the case on what advice was given and what instructions were received, rather than on a contested “no ordinary solicitor would have done this” finding.

Hughes-Holland v BPE Solicitors & Anr [2018] AC 599 (“Hughes-Holland”)

Hughes-Holland is a cornerstone authority on distinguishing “but for” causation from the scope of duty question: even where negligence is a factual cause, liability is confined to losses that fall within the purpose of the duty assumed.

Lady Tait used it (with later UKSC cases) to test whether the pursuer’s losses—losses said to arise from inability to trade due to defects—were the kind of losses the defenders’ conveyancing duty regarding completion certification was meant to prevent.

Manchester Building Society v Grant Thornton UK LLP [2022] AC 783 (“MBS”)

Lady Tait drew from MBS the structured approach: identify “what are the risks of harm … against which the law imposes … a duty to take care”, determine the duty’s purpose objectively, and ask whether the loss represents the fruition of that risk.

This was central to the court’s (alternative) conclusion that the pursuer’s losses arose from defective workmanship and the need for remedial works, rather than from the risk that a completion certificate might be delayed or not accepted.

Meadows v Khan [2022] AC 852 (“Meadows”)

Meadows refined and illustrated the “scope of duty” analysis, reinforcing that professionals do not become insurers for all downstream consequences; liability tracks the specific risk the advice/duty was meant to address.

Lady Tait cited Meadows alongside MBS to emphasise that the court must not simply ask whether the transaction would have happened, but must pinpoint whether the loss complained of is within the adviser’s assumed responsibility as defined by the advice’s purpose.

3.2 Legal Reasoning

(a) The duty in conveyancing when completion certificates are not available

The court proceeded on a point that was “not disputed” between parties: Mr Soper had a duty to (a) insist upon retention of clause 17.3 (production of completion certificates), or (b) if accepting deletion, procure other adequate protection, unless (c) he received clear and informed instructions from the pursuer not to insist on such protection.

The judgment’s practical message is that conveyancers can proceed pragmatically (e.g., by undertaking/retention) where immediate certification is unavailable, but they must either secure enforceable protection or obtain demonstrably informed client instructions to accept the risk.

(b) Proof turned on credibility and evidence of advice/instructions

The key determinative step was Lady Tait’s assessment of the evidence. Despite poor file-noting, the court accepted Mr Soper’s evidence that he:

  • met the pursuer to discuss the qualified acceptance;
  • advised that no completion certificate would be available at settlement and explained implications (including enforcement risk);
  • discussed reliance on the architect’s letter, engineer material, lender valuation/reinspection, and local authority inspections; and
  • was instructed to proceed without sending the drafted protective missive.

The pursuer, by contrast, was found unreliable primarily due to lack of recall and inconsistency (including querying documents apparently sent from or signed by her). Importantly, the court treated her evidence as not advancing a coherent competing narrative; rather, she “simply could not remember.” That evidential posture made it easier for the defenders’ account—supported by annotations on the qualified acceptance and the existence of an unsent draft protective missive—to prevail.

(c) Scope of duty as a limiting principle (even if breach were proved)

Lady Tait then articulated a decisive alternative ground: even if there had been breach (e.g., proceeding without an undertaking), the losses claimed were not within the scope of the relevant duty.

The court separated:

  • the “completion certificate risk”: delay or absence of local authority acceptance of a completion certificate (with statutory implications for occupation/use); from
  • the “defective workmanship risk”: that the building works were badly done and would later require extensive remedial works.

On the agreed timeline, the completion certificate for the development was accepted by Dundee City Council on or around 30 January 2013. The pursuer’s own programme could not have yielded trading until after obtaining her own building warrant (granted 17 December 2012) plus an anticipated fit-out period. The court concluded that the temporary absence of the completion certificate at settlement did not cause the loss; the operative problem was defective construction, and acceptance of a completion certificate would not have guaranteed defect-free works in any event (as confirmed by the skilled witness evidence).

(d) Quantum (if it had arisen)

Lady Tait was not persuaded that the business plan reliably proved loss of profits. The plan was held speculative—particularly regarding immediate profitability of new income streams, understated running/staffing costs, and unclear funding for refurbishment (where quotations substantially exceeded budget).

For inconvenience, the court accepted some disruption but found the evidence too vague to justify the claimed figure; an award would have been modest (capped at £5,000 on the court’s hypothetical assessment).

3.3 Impact

  • Reinforcement of “informed instruction” as a defence in conveyancing negligence: where a client is fully advised of a certification/protection gap and elects to proceed, courts may be slow to reallocate that commercial risk to solicitors—especially where the client was strongly motivated to complete.
  • Practical litigation significance of “scope of duty” in Scotland: the judgment demonstrates that even if breach is arguable (e.g., failure to secure an undertaking), pursuers must still connect the type of loss to the risk the duty was meant to avert. Defective-building losses may be characterised as outside the solicitor’s assumed responsibility where the alleged failure concerns certification/contractual protection timing.
  • Evidential warning: lack of file notes did not defeat the defenders here, but the case underscores that credibility battles can be determinative; contemporaneous written advice/instructions would reduce uncertainty for both sides.
  • Business-plan losses remain difficult: ambitious, under-costed projections without robust corroboration are unlikely to satisfy the balance of probabilities for substantial loss of profits.

4. Complex Concepts Simplified

  • Missives / qualified acceptance: the Scottish contractual exchange for property sales. A “qualified acceptance” accepts the offer but with changes; acceptance “de plano” means accepting those changes outright.
  • Suspensive condition: a condition that must be satisfied before the contract becomes binding. Here, an offered suspensive condition was deleted.
  • Completion certificate (local authority acceptance): formal acceptance by the local authority that work complies with the building warrant requirements; it is not a guarantee that the building is defect-free.
  • Undertaking: a solicitor’s binding professional promise to do something (e.g., deliver a document within a set time). It is often used to bridge timing gaps at settlement.
  • Hunter v Hanley test: Scottish professional negligence standard—whether the professional acted in a way no ordinarily competent professional would have done.
  • Scope of duty: a legal control on liability; even if negligence is a factual cause, damages are limited to losses arising from the particular risk the duty was meant to protect against.
  • Decree of absolvitor: dismissal in favour of the defender after proof, effectively absolving them from liability.

5. Conclusion

Lady Tait’s decision is significant for two interlocking propositions. First, in conveyancing negligence concerning missing completion certificates, a solicitor will not be held in breach where the court is satisfied that the client received clear advice about the absence of certification and its risks and nonetheless gave clear and informed instructions to proceed without further contractual protection. Second, even where breach might be established, the court will confine liability by applying the modern scope of duty analysis: losses must represent the fruition of the specific certification-related risk the solicitor’s duty addressed, not broader losses attributable to defective building works and business disappointment.
