A lost limitation claim is a professional negligence claim against a solicitor or other professional whose conduct caused the client to lose a valuable claim through expiry of the limitation period — a long-standing category of solicitors PI and one of the highest-frequency causes of loss.
Lost limitation claims are characterised by their clarity on liability (the limitation expired; the underlying claim is barred) and by the difficulty of their quantum analysis (what was the lost claim worth, and what would the client have recovered if it had been pursued in time?).
The professional duty is to advise on, monitor and protect the client’s limitation position. Failure can have catastrophic consequences for the client and is correspondingly significant for the professional’s PI insurer.
The framework includes:
The Supreme Court’s decision in Perry v Raleys clarified the methodology for assessing damages in lost-claim cases. The claimant must prove (i) that they had a real and substantial chance of success on the underlying claim (the Allied Maples test for loss of a chance) and (ii) the value of that chance.
The court applies a two-stage analysis: probabilities for elements that depend on the claimant’s own past conduct (decided on the balance of probabilities); loss-of-chance valuation for elements that depend on a hypothetical third party’s response (the underlying defendant, the court, expert evidence outcomes).
A typical lost limitation claim:
The client engaged the solicitor to pursue a personal injury claim, a commercial dispute or another matter with a defined limitation period. The solicitor failed to issue proceedings within the limitation period. The underlying claim became time-barred; the client lost the value of the claim.
Defence analysis:
First, was there a breach of duty? Failure to issue proceedings within limitation is almost invariably a breach, save in exceptional circumstances (extension granted, limitation defence not available against the underlying defendant).
Second, did the breach cause loss? The client must show the underlying claim had real prospects of success. Perry v Raleys confirmed that frivolous or hopeless underlying claims yield no damages — the claimant must prove the chance was substantial.
Third, what is the quantum? The defence team reconstructs the underlying claim and asks what would have been recovered. This typically involves:
For PI insurer perspective, the defence approach is heavily quantitative. The solicitor’s apparent breach is rarely in dispute; the defence focuses on demonstrating that the underlying claim’s value was lower than the client alleges.
Aggregation analysis applies where multiple lost-claim clients arise from the same firm error. Woodman analysis informs whether multiple lost-limitation claims aggregate.
The Limitation Act 1980 section 14A (latent damage) is critical to the secondary limitation period. The client’s claim against the solicitor for losing the limitation must itself be brought within the limitation period applicable to professional negligence — typically six years from the breach or three years from when the client had knowledge of the negligence.
“PI claim limitation lost” — the most common; client had a PI claim that expired three years after the accident.
“Commercial claim limitation lost” — six-year contract/tort limitation; often lower frequency but higher individual value.
“Latent damage claim limitation lost” — under section 14A, special limitation rules apply.
“Time-barred appeal lost” — the solicitor failed to lodge an appeal in time, losing the appeal opportunity.
“Cascade limitation loss” — where the loss of one limitation triggers loss of other connected limitations.
A claimant client engaged a solicitors firm in November 2022 to pursue a road traffic accident PI claim from August 2022. The three-year limitation expired August 2025. The solicitor failed to issue proceedings; the limitation was missed. The client’s underlying PI claim is time-barred.
Notification: the client makes a complaint and the firm notifies its PI insurer in October 2025. Coverage attaches.
Defence analysis: breach admitted. The defence focuses on quantum of the underlying lost claim.
The underlying PI claim: serious neck injury with 18-month recovery and chronic residual symptoms. Pleaded special damages £140,000; general damages £18,000; total approximately £158,000. The underlying defendant insurer’s settlement position (had the claim been pursued in time) is estimated by a PI specialist at £95,000 to £135,000 with a midpoint of £115,000.
Loss-of-chance analysis: the claim would have had high prospects of success (clear liability, well-documented injury, contingency for tail risk approximately 80%). Recoverable damages against the solicitor: £115,000 × 80% = £92,000.
Settlement: £85,000 plus costs at mediation 7 months after notification.
The firm’s PI policy responds within limits. The lost-limitation claim is one of three similar matters within the firm’s recent diary; the policy’s aggregation clause is examined but the three matters do not have sufficient connection to aggregate.
