Got an ADA Demand Letter? Here's What to Do Next

What a demand letter means

An ADA accessibility demand letter is a formal written notice informing you that someone has encountered barriers on your website that they believe violate the Americans with Disabilities Act, and that they intend to pursue legal action unless the issue is remediated.

For many businesses, receiving one is alarming. The combination of legal language, tight timelines, and unfamiliar technical claims can make the situation feel more unmanageable than it actually is.

The reality: demand letters have become a routine part of the web accessibility enforcement landscape in the United States, and organizations that respond thoughtfully — with genuine remediation, not just legal posturing — almost always reach resolution without full litigation.

Understanding the process is the first step.

Where demand letters come from

ADA Title III prohibits discrimination in places of public accommodation. Since a landmark 2019 federal ruling, the dominant legal interpretation is that websites operated by businesses open to the public are “places of public accommodation” under Title III.

Letters come from a few sources:

Law firms specializing in accessibility litigation represent clients with disabilities who have encountered genuine barriers, as well as operating in what critics call “drive-by” litigation: systematically scanning websites with automated tools, identifying violations, and sending demand letters at scale. Both are legally valid under current interpretations.

Individual plaintiffs who genuinely encountered an accessibility barrier — could not use a checkout, couldn’t access account information, were unable to navigate your site with a screen reader — sometimes retain legal counsel and pursue claims directly.

The Department of Justice (DOJ) can also issue compliance letters or initiate investigations, though this is less common for smaller businesses than private party actions.

The two types of letters

Demand letters seeking settlement

The most common form. The letter describes the alleged violations, often identifies specific WCAG failures, and proposes settlement terms — typically a commitment to remediate within a set timeframe, sometimes accompanied by a monetary payment for attorney’s fees and sometimes a small damages figure.

Many of these settle without court involvement. The plaintiff wants a fixed site and legal fees covered. The defendant wants to avoid litigation. Reaching an agreement is usually in both parties’ interests.

Complaints filed in court

If a demand letter is ignored or settlement negotiations break down, the plaintiff may file a lawsuit. Accessibility lawsuits in the US have numbered in the thousands each year. Most settle before trial, but litigation is expensive regardless of outcome.

How to respond: a step-by-step approach

Step 1: Don’t ignore it

This is the most important step. A demand letter that goes unanswered is treated as evidence of bad faith. It signals that you’re not taking the matter seriously, which strengthens the plaintiff’s position and often accelerates escalation to court filing.

Acknowledge the letter promptly, even if only to say you’ve received it and are reviewing it.

Step 2: Engage legal counsel

If your organization doesn’t have in-house counsel familiar with ADA Title III, find outside counsel who does. The legal landscape for website accessibility is active and nuanced — you want advice from someone who has handled these cases specifically.

Step 3: Commission an accessibility audit

You need to understand the actual state of your site — both to respond to the specific allegations in the letter and to understand the full scope of remediation required.

Don’t rely only on automated scanning. Automated tools reliably catch only 30–40% of WCAG failures. A manual accessibility audit or an audit conducted by people with disabilities will give you a complete picture, which is also what your legal team needs to negotiate from an informed position.

Step 4: Begin remediation

The fastest path to resolution is demonstrating genuine progress. This doesn’t mean your site needs to be fully compliant before negotiations conclude — but showing that you’ve identified the issues and begun fixing them meaningfully improves your position.

Prioritize the highest-impact barriers first: checkout and payment flows, account access, and any functionality that directly limits a disabled person’s ability to use your core service.

Step 5: Negotiate

Most ADA accessibility demand letters settle with a combination of:

• A remediation plan with specific milestones and timelines
• Commitment to ongoing monitoring and testing
• A payment for attorneys’ fees (amounts vary widely)
• Sometimes a small additional payment for damages

Settlement agreements often include a monitoring period during which the plaintiff’s counsel can verify that promised remediations have been completed. Having a credible compliance program — regular audits, documented fixes, an accessibility statement — makes the monitoring period go smoothly.

The serial filer phenomenon

A meaningful share of accessibility demand letters are sent by a small number of law firms that systematically target websites across industries. The letters are often templated; the violations cited are often the same few automated-scanner-detectable failures repeated across hundreds of sites.

This practice is controversial. Critics argue it exploits accessibility law for financial gain rather than genuine advocacy. Defenders argue it creates real pressure on businesses to remediate barriers that would otherwise persist indefinitely.

Regardless of where you stand on the debate, the legal liability is real. If your site has WCAG failures, a demand letter based on those failures is legally actionable. The practical response — fix the accessibility issues — is the same whether the letter came from genuine advocacy or systematic litigation.

Preventing the next letter

The best defense against accessibility demand letters is having a site that meets accessibility standards. This is not a one-time project; every new feature, component, or content update can introduce new barriers.

Organizations that effectively prevent accessibility litigation treat it as a continuous quality concern:

• Regular automated scanning embedded in their development pipeline catches the detectable issues before they ship. Our CI/CD accessibility integration service makes this part of the build process.
• Scheduled manual audits surface the issues automated tools miss.
• An accessible accessibility statement demonstrates good faith and gives users a way to report barriers before they seek legal remedies.
• Team training ensures developers, designers, and content authors don’t introduce new barriers unknowingly.

If you’ve received a demand letter and need to understand your site’s current position quickly, a free automated scan is the fastest starting point. For the complete picture your legal team needs, reach out to discuss a full audit.
