Bringing a professional negligence claim in England and Wales can feel like stepping onto a financial tightrope. Even when the underlying case looks strong, the cost of court fees, expert reports, and counsel can mount quickly, and the prospect of paying the other side's costs if things go wrong puts many claimants off before they start.
After the Event (ATE) insurance exists to take some of that sting out of litigation. This guide walks through what ATE insurance actually does in a professional negligence context, how premiums tend to be structured, where it fits alongside conditional fee arrangements, and the practical points both claimants and the solicitors advising them should weigh up before committing to a policy.
Overview
After the Event insurance is a form of legal expenses cover taken out once a dispute has already arisen, typically shortly before or during the early stages of a claim. Unlike Before the Event cover bundled into household or motor policies, ATE is bought specifically for the matter in hand.
In professional negligence cases, the policy is usually designed to protect the claimant against adverse costs, meaning the legal costs they might be ordered to pay the defendant if the claim fails. It can also cover their own disbursements, things like court fees, expert witness charges, and barristers' fees paid on a non-conditional basis.
Cover limits, exclusions, and premium structures vary significantly between insurers. Many ATE policies in this area are written on a deferred and contingent basis, so the premium only becomes payable if the claim succeeds. Since the Legal Aid, Sentencing and Punishment of Offenders Act 2012, ATE premiums are generally no longer recoverable from the losing defendant in most civil claims, so the cost usually comes out of the claimant's damages.
Key steps
Work out whether you actually need ATE cover. Not every professional negligence claim justifies the expense of a policy. If the case is modest, if the defendant has limited assets, or if costs exposure is low, the premium may eat too much of any eventual recovery. Sit down with your solicitor and map out the realistic costs risk before shopping for a policy.
Gather the case information an insurer will want to see. Underwriters assess risk based on the strength of the claim, the identity of the defendant, the likely quantum, and the evidence available. Expect to provide a case summary, key correspondence, any expert opinion obtained so far, and a costs budget. The more coherent the picture, the better the terms you are likely to get.
Compare policies on cover, exclusions, and premium structure. Headline cover limits matter, but so do the small print exclusions, the position on discontinuance, and whether the premium is staged, deferred, or payable up front. Ask how the insurer handles changes in the case, such as a shift in quantum or the addition of new defendants, and how cover responds if Part 36 offers come into play.
Understand how the premium interacts with your damages. In most current professional negligence claims, the ATE premium is not recoverable from the defendant, so it is typically paid from damages at the end. Make sure you have a clear, written explanation from your solicitor of how the premium, any success fee under a conditional fee agreement, and other deductions will stack up against your likely recovery.
Keep the insurer properly informed as the case develops. ATE policies usually contain ongoing disclosure obligations. Material developments, such as a poor expert report, a significant settlement offer, or a change in prospects of success, normally need to be reported. Failing to do so can give the insurer grounds to avoid the policy at exactly the point you need it most.
Q Does ATE insurance cover my own solicitor's fees?
Usually not. Own-side solicitor fees in professional negligence claims are more often handled through a conditional fee agreement, where the solicitor only gets paid if the case succeeds. ATE typically focuses on adverse costs and disbursements such as court fees, expert reports, and counsel's fees. Some policies can be structured to include certain own-side costs, but this varies and tends to push the premium up.
Q Can the ATE premium be recovered from the losing defendant?
For most civil claims in England and Wales, ATE premiums are no longer recoverable from the defendant following reforms that took effect in April 2013. There are limited exceptions, for example certain clinical negligence expert report premiums, but professional negligence claims generally fall within the standard rule. The premium is normally paid from the claimant's damages at the end of the case.
Q What happens if I lose the case?
That is precisely what a good ATE policy is designed for. Subject to the policy terms, the insurer should cover the adverse costs you are ordered to pay the defendant, along with any covered disbursements you have incurred. Deferred and contingent policies also mean the premium itself is generally not payable where the claim loses, although you should always read the cancellation and discontinuance clauses carefully.
Q Is ATE the same as a conditional fee agreement?
No, but the two are often used together. A conditional fee agreement is the arrangement between you and your solicitor about when and how they get paid, typically on a no win, no fee basis with a success fee if you win. ATE insurance is a separate contract with an insurer that protects you against the financial fallout of losing, particularly adverse costs. They complement each other rather than duplicate cover.
Q When should ATE insurance be put in place?
Generally as early as possible once a claim is being seriously pursued, and certainly before any step that creates meaningful costs exposure, such as issuing proceedings. Insurers sometimes decline cover or charge more if the case is presented to them late. Your solicitor should flag the question of ATE at the initial strategy stage rather than leaving it until litigation is already underway.
Q Will every insurer take on a professional negligence case?
No. Professional negligence is a specialist area, and only a limited number of insurers write ATE for these claims. Insurers often have minimum prospects of success criteria, commonly around 60 percent or higher, and may decline cases against certain types of defendant or with particular causation difficulties. Your solicitor's experience in placing cover can make a real difference to the terms you are offered.
Q Can the policy be cancelled partway through the case?
Yes, and this is one of the most important parts of the wording to understand up front. Insurers typically reserve the right to withdraw cover if the prospects of success drop below a set threshold, if you fail to cooperate, or if you reject a reasonable settlement offer. Cancellation can leave you personally exposed to adverse costs, so the triggers and consequences need to be properly explained before you commit.
ATE policies vary widely on cover, exclusions, and how the premium comes out of any damages you recover. An experienced legal adviser can talk you through how ATE tends to work in professional negligence claims based on what you describe, so you can weigh it up properly before committing.
