The World's Most Complete Guide to No Win No Fee Law

Comprehensive, authoritative legal information covering contingency fee arrangements in the United States and conditional fee agreements in the United Kingdom.

What Is No Win No Fee?

"No win no fee" is a broad term for legal funding arrangements where a client does not pay their lawyer's professional fees unless their case succeeds. It exists in various forms across common-law jurisdictions worldwide, but the two most developed systems are in the United States and the United Kingdom.

In the United States, this is known as a contingency fee agreement. The attorney agrees to represent the client in exchange for a percentage of the damages recovered — typically between 33% and 40%. If the case is lost, the attorney receives no fee, though the client may still be responsible for case costs such as court filing fees and expert witness charges.

In the United Kingdom, the equivalent arrangement is a Conditional Fee Agreement (CFA). Under a CFA, the solicitor charges their normal base costs plus a "success fee" — an uplift of up to 100% of those costs — only if the case wins. For personal injury claims, the success fee is capped at 25% of the damages awarded for pain, suffering, and loss of amenity. The UK also permits Damages-Based Agreements (DBAs), which work more like US contingency fees.

Both systems exist to ensure access to justice for people who cannot afford to pay legal fees upfront. However, the rules, regulations, caps, and cost consequences differ significantly between — and even within — each country.
