ADA website lawsuits: why the numbers don't match

If you've searched for ADA website lawsuit statistics, you've seen numbers that don't agree. Vendor pages tend to quote whichever figure suits their pitch. This post lines up the three main trackers, explains why their counts differ, and pulls out what they agree on, which is the part that should shape what you do.

The evidence at a glance

Why do the trackers report different numbers?

Each tracker draws a different boundary around "ADA website lawsuit."

The biggest difference is state courts. UsableNet counted 3,195 federal cases, close to Seyfarth's 3,117, plus 1,919 cases in New York and California state courts. Seyfarth deliberately excludes state courts and notes that a significant number of demand letters and state lawsuits fall outside its count (Seyfarth, 2026).

So none of these numbers is the full picture. Demand letters, which often settle before any lawsuit is filed, aren't counted by anyone.

What do all the trackers agree on?

1. Filings went up in 2025

Seyfarth's federal count rose 27%, from 2,452 in 2024 to 3,117 in 2025. Website cases made up 36% of all federal ADA Title III lawsuits, up from 28% the year before (Seyfarth, 2026).

2. A few states account for most federal cases

In Seyfarth's 2025 federal data, New York had 1,021 filings, Florida 961 (nearly double its 470 in 2024) and Illinois 585. California had only 4 federal filings, because California plaintiffs usually file in state court (Seyfarth, 2026).

3. Ecommerce is the main target

70% of the 2025 filings UsableNet tracked were against ecommerce businesses, and 36% of the top 500 ecommerce retailers received at least one lawsuit (UsableNet, 2025).

4. Small businesses get sued too

Companies with over $25 million in annual revenue were the target in 36% of UsableNet's cases. That means most cases targeted smaller businesses (UsableNet, 2025).

5. Being sued once doesn't stop the next suit

1,427 federal cases, 45% of federal filings, targeted companies that had already been sued (UsableNet, 2025). Settling one case without fixing the site leaves the door open.

6. A small group of plaintiffs files most cases

In EcomBack's data, 33 plaintiffs filed more than half of all 2025 lawsuits. Across all filings, 251 plaintiffs and 40 law firms were involved (EcomBack, 2026).

7. Accessibility widgets didn't prevent lawsuits

UsableNet counted 1,416 lawsuits against companies using accessibility widgets in 2025 (UsableNet, 2025). EcomBack found nearly 25% of lawsuits targeted sites with such tools and concluded they proved ineffective at preventing litigation (EcomBack, 2026). In 2025 the US Federal Trade Commission also finalised a $1 million order against overlay vendor accessiBe over claims that its tool could make sites compliant.

What problems do these lawsuits usually cite?

Most complaints describe barriers a screen-reader or keyboard user hits on a real page. The WebAIM Million 2026 shows how common those barriers are: 95.9% of the top million home pages had detectable WCAG failures, with low-contrast text on 83.9%, missing image alt text on 53.1% and missing form labels on 51% (WebAIM, 2026).

The good news is that these are among the most fixable problems on the web. Most are detectable by automated testing, and many take minutes to fix once found.

What should a site owner do?

1. Audit your key pages now. Start with the homepage, product or pricing pages, and sign-up or checkout. Fix contrast, labels, alt text and keyboard access first.
2. Test with a real browser and a keyboard. Tab through every page. Check that focus is always visible and never hidden behind sticky headers or banners.
3. Don't rely on a widget. The data shows sites with overlays are still sued. Fix the underlying code instead.
4. Fix, don't just settle. Nearly half of federal filings hit companies already sued. A settlement without fixes invites the next case.
5. Re-audit after every release. New features and content can bring new barriers.
6. Get expert help for high-risk sites. If you run a large ecommerce site or have received a demand letter, combine automated testing with a manual accessibility audit and legal advice.

How ProCurveUX helps

ProCurveUX checks your live pages against WCAG 2.2 AA rules alongside UX and conversion checks. It loads each page in a real browser on desktop and mobile, tabs through it, and flags issues such as low contrast, missing labels, invisible focus and focus hidden behind sticky elements. Every finding includes a screenshot, CSS selector and fix, ranked by impact.

Automated testing finds many issues but can't confirm full WCAG conformance. ProCurveUX is a fast first pass, not a legal compliance certificate.
