ATE Insurance

Protect your clients from disbursements and adverse costs if your case loses. Strengthen your firm’s litigation offering. Our ATE policies feature fully deferred premiums, fast underwriting decisions, and a simple online portal — designed around the way law firms actually work.

What Is After the Event Insurance?

After the Event (ATE) insurance is a legal expenses policy taken out after a dispute has arisen but before legal proceedings begin. It protects your client against the financial risk of losing their case by covering adverse costs and any disbursements your client would be ordered to pay the opposing party should their claim be unsuccessful.

In practical terms, ATE insurance removes the single biggest barrier to litigation: cost. It gives your clients the confidence to pursue valid claims without the fear of a devastating costs order if things don’t go their way.

For commercial clients, ATE also allows litigation risk to be taken off the balance sheet entirely, rather than requiring a provision in the accounts.

Who Is ATE Insurance For?

We work exclusively with law firms, solicitors, and insolvency practitioners across England and Wales. Whether you’re a sole practitioner handling clinical negligence claims or a large firm running complex commercial disputes, we tailor ATE solutions to fit your practice.

Prosperity Insurance is built for firms who want:

  • A dedicated ATE partner who understands litigation from the solicitor’s perspective
  • Delegated authority facilities with pre-agreed premiums — no referral to the insurer on every case
  • No minimum volume requirements, so smaller firms get the same access as larger ones
  • Prosperity Insurance deals with over 350 law firms on its panel who have access to its various services. You are in safe, expert hands with us.
  • Minimal in-life case reporting requirements, keeping your admin burden low
  • An easy-to-use online portal for issuing policies in minutes

Our management team combines over 90 years of insurance and legal experience. We don’t just process applications — we assess risk alongside you and work to find the right policy for every case.

Whether you handle 5 cases a year or 500, we’ll build a facility that works for your firm.

What Does ATE Insurance Cover?

If your client’s case is unsuccessful, an ATE policy covers:

  • Adverse costs — the opponent’s legal fees that the court orders your client to pay
  • Own disbursements — the fees your client has incurred to progress the claim (expert reports, court fees, etc.)

Case Types We Cover

We offer ATE insurance across a broad range of litigation and contentious work, including both delegated authority facilities and individually assessed bespoke policies.

Core areas:

Commercial and specialist areas:

  • Professional negligence
  • Director and shareholder disputes
  • Construction and property disputes
  • Fraud and financial mis-selling
  • Contentious trusts and probate
  • Defamation
  • Pensions disputes
  • Insurance litigation
  • Arbitration proceedings
  • Banking and finance litigation
  • Business interruption

This list isn’t exhaustive. If you have a case type that isn’t listed, contact us — we’re always happy to consider new areas of litigation.

Why Your Clients Need ATE Insurance

Litigation carries inherent financial risk. For many clients — whether individuals or businesses — the prospect of an adverse costs order is enough to stop a valid claim in its tracks.

ATE insurance changes that equation entirely.

For individual clients, it provides a safety net. If the case is lost, the policy covers adverse costs and disbursements. Combined with a conditional fee agreement, your client can pursue their claim with no financial exposure.

For business clients, ATE removes litigation risk from the balance sheet. Instead of making a provision in the accounts for potential adverse costs, the risk is transferred to the insurer — freeing up capital and giving boards the confidence to authorise proceedings.

For your firm, offering ATE demonstrates a proactive, client-first approach. It protects the solicitor-client relationship by ensuring your client is fully informed about costs protection from the outset — in line with the SRA Code of Conduct’s expectations around costs transparency and funding options.

ATE insurance should be arranged as early as possible. Delaying can mean higher premiums, reduced cover, or — in some cases — cover not being available at all.

  1. Your client is protected

Once the policy is in force, your client can proceed with confidence. You keep Underwriters updated at key stages (issuing proceedings, settlement offers made or recieved, expert reports, when a defence is served, if/when a trial date is obtained and any material changes to the cases prospects of success or if it drops below 51%), and continuation of cover is maintained.

Premiums are fully deferred and only payable if the case succeeds. If the case is lost, the premium is fully self-insured as part of the claim.
