Duty and scope
What was the professional actually engaged to do? The engagement letter, contract, instructions, agreed scope, limitations and subsequent communications can be central to understanding what responsibility was assumed.

Professional Negligence Claims Defence
Professional Negligence Claim Made Against You?
An allegation of professional negligence is not the same thing as establishing liability. The claim still needs to be tested against the scope of the engagement, the professional standard, what actually happened, causation and the loss being claimed.
Insurance Dispute Service provides fixed-fee claims analysis, defence preparation and litigation support for professionals and businesses, with specialist Direct Access barrister involvement where appropriate.

The Claim
What actually needs to be tested?
Professional negligence disputes are rarely resolved simply by asking whether somebody made a mistake. The more useful questions concern the professional’s actual responsibilities, the standard required, what difference the alleged error made and whether the claimed loss follows from it.
The alleged breach
What conduct is said to have fallen below the required professional standard? The allegation needs to be compared with the work undertaken, the circumstances at the time and, where necessary, appropriate professional or expert evidence.
Causation
Even where something could have been done differently, the claim still needs to address whether that act or omission actually caused the financial consequence relied upon. Other events may have contributed to or caused the outcome.
Loss
What is the claimant actually seeking to recover and how has that figure been calculated? Valuation, mitigation, alternative outcomes and the documentary basis for the claimed loss may all require examination.
The precise legal issues depend on the claim being made.
The Professional Negligence Pre-Action Protocol itself covers
alleged negligence and can also apply to equivalent breach of
contract or breach of fiduciary duty. The allegations and legal
basis therefore need to be examined in the individual case.
Start With the Retainer
The scope of the engagement can change the whole case.
A claimant may describe what they expected the professional to do. That is not necessarily the same as what the professional actually agreed to do.
The written retainer, terms of engagement and contemporaneous communications may show that the work was narrower, conditional on information supplied by the client, subject to assumptions, or accompanied by warnings which later become important.
- Engagement letters and terms of business
- The instructions actually given
- Changes to the agreed scope
- Assumptions and information supplied by the client
- Warnings, reservations and qualifications
- Advice given and decisions ultimately made by the client
Evidence Before Hindsight
What do the documents created at the time actually show?
Professional-negligence claims are often considered long after the advice or work was carried out. That makes contemporaneous documents particularly important.
A clear chronology can turn a collection of old emails and
files into a coherent defence.
01
Emails and correspondence
What was requested, what information was supplied, what advice was given and what was understood at each stage?
02
Working papers and professional records
Internal notes, calculations, reports, attendance notes, valuations and working documents may explain the reasoning behind the professional’s actions.
03
The claimant’s own decisions
What choices did the client make, what information did they possess and what would they realistically have done differently if the alleged error had not occurred?
04
Expert evidence
Some disputes require expert evidence on professional standard, causation or quantification. The Professional Negligence Protocol expressly recognises that different expert disciplines may be needed for different issues.
05
The financial evidence
A claimed loss should be understood rather than simply accepted as the figure appearing in the Letter of Claim. The assumptions and calculations behind it may need testing.
The Insurance Position
Professional indemnity cover can become part of the dispute.
A professional negligence allegation should also trigger a careful review of the relevant insurance position. Questions can arise about notification, the correct policy year, exclusions, excesses, control of the defence or whether the insurer is reserving its position on indemnity.
Sometimes the professional is therefore dealing with two different disputes: the liability claim being made against them and a separate question about whether their insurer will provide the expected protection.
Before Proceedings
Professional negligence claims usually have a structured pre-action stage.
Where the Professional Negligence Pre-Action Protocol applies, the parties are expected to identify the issues, exchange relevant information and explore whether the dispute can be resolved before court proceedings become necessary.
Stage 01
Preliminary Notice
A claimant who considers there is a reasonable chance of bringing a claim is encouraged to give the professional early written notice, including an outline of the grievance and, where possible, a general indication of value.
Stage 02
Letter of Claim
Once the claimant considers there are grounds for a claim, the Protocol anticipates a detailed Letter of Claim identifying the facts, allegations, causation case, claimed loss, key documents and expert position.
Stage 03
Investigation
The Letter of Claim should normally be acknowledged within 21 days. The professional then normally has three months from the Letter of Acknowledgment to investigate and respond, unless an extension is agreed.
Stage 04
Response and resolution
The response should deal substantively with the allegations. The Protocol also expects the parties to consider settlement and appropriate forms of alternative dispute resolution before litigation becomes the only remaining route.
How We Work
Build a structured defence without automatically starting with an open-ended solicitor retainer.
Insurance Dispute Service provides experienced claims and litigation support through defined stages of work. The objective is to identify what actually needs doing and prepare the case accordingly.
Our own work can be scoped and priced on a fixed-fee basis.
Barrister, expert, court and other third-party fees are
separate where required and should be understood before they
are incurred.
01
Analyse the claim
Understand the allegations, contractual scope, professional duties, causation case, claimed loss and any obvious gaps or inconsistencies.
02
Build the documentary position
Create the chronology, identify the important documents and organise the factual evidence around the issues that matter.
03
Examine the insurer’s position
Where insurance is involved, consider notification, policy response and any reservation-of-rights or indemnity issue alongside the underlying liability dispute.
04
Prepare for specialist legal input
Where appropriate, organise the case so a specialist Direct Access barrister can advise on the legal merits, drafting, strategy or advocacy efficiently.
05
Support the next stage
Depending on the case, that may include practical litigation support, evidence organisation, document management, bundles, hearing preparation and barrister-ready case material.

Important Distinction
Construction professionals follow a separate pre-action protocol.
The Professional Negligence Pre-Action Protocol does not apply to claims against architects, engineers and quantity surveyors. Professional-negligence claims against those professions fall within the separate Pre-Action Protocol for Construction and Engineering Disputes.

Professional negligence claims defence
Does a professional negligence allegation mean I am liable?
No. An allegation is the claimant’s case. The underlying scope of duty, alleged breach, facts, causation, evidence and loss still need to be examined before liability can be assessed.
Can a claim fail even if a mistake was made?
The existence of an error does not by itself answer every question in a professional-negligence claim. The legal effect of the error, whether it caused the loss alleged and the amount of recoverable loss can be separate issues.
Should I notify my professional indemnity insurer?
The relevant policy wording should be checked promptly. Professional indemnity policies commonly contain provisions dealing with notification of claims or circumstances, and the applicable requirements can be important.
What if my PI insurer appoints solicitors?
That is common and may provide the main legal defence to the claim. There may still be separate questions about the insurance position, your own evidence or wider commercial interests which you want to understand independently.
Do I have to wait until court proceedings before instructing a barrister?
No. A suitable Public Access barrister may be instructed before proceedings for specialist legal advice or drafting. The precise route depends on the case and the work that needs to be carried out.
Important information
Insurance Dispute Service provides claims analysis, case preparation and litigation support. The appropriate route depends on the claim, policy, evidence, procedure and work required.
Public Access enables suitably registered barristers to accept direct instructions. Conduct of litigation is a separate reserved activity and appropriate authorisation is required where a professional undertakes that work on a client’s behalf.
This page provides general information and is not legal advice. No particular outcome is guaranteed. Limitation periods, court deadlines, insurance notification requirements and applicable pre-action procedures should be checked for the individual matter.
