Writing a disclaimer that limits your liability comes down to four things: identify exactly what you could be sued over, match each risk to language the law actually recognizes, present it where people will see it, and get affirmative consent whenever you can. A disclaimer is a notice that tells users, customers, or clients what you are and are not responsible for. It is not a force field. No disclaimer protects you from fraud, intentional misconduct, or gross negligence, and courts routinely strike down language that is buried, vague, or wildly one-sided. Within those limits, though, a well-drafted disclaimer is one of the cheapest and most effective pieces of legal protection a business can have.
Draft It in Steps, Not From a Template
The most common mistake is copying a disclaimer from another website. Your risks are not someone else’s risks, and generic language rarely covers the specific thing you will actually get sued over. Work through the following sequence instead.
List your exposures. Write down every product, service, or piece of content you offer. For each one, ask what could go wrong if a user relied on it. A fitness blog has different risks than an online store selling power tools, and both have different risks than a consulting practice.
Match each risk to a disclaimer type. Informational content needs a “not professional advice” notice. Products need warranty language. Affiliate links need financial relationship disclosures. User-generated content needs an accuracy disclaimer. A single paragraph trying to cover all four will cover none of them well.
Check your regulatory obligations. Some industries require exact wording set by a federal agency. Dietary supplements, investment advisers, and anyone making paid endorsements all have non-negotiable requirements covered further down.
Write in plain language. State what you are disclaiming and why. “This blog provides general information about nutrition and is not a substitute for advice from your doctor” works better than a sentence stuffed with “pursuant to” and “herein.” Courts read plain English the same way users do.
Say what the disclaimer covers and what it does not. Vague disclaimers get thrown out. If your warranty disclaimer applies only to implied warranties and not to express promises you made in marketing copy, write that in.
Add an effective date. This lets you track versions and shows a court you maintain the document. Update the date every time you revise the language.
Have an attorney review the final draft. Attorney review for a standard business disclaimer typically runs $150 to $500 depending on complexity and location. It is one of the cheaper forms of legal insurance available.
Know What the Law Will Not Let You Disclaim
Before you write a word, understand the categories courts refuse to enforce. A disclaimer that reaches into these areas is at best useless and at worst evidence that you knew what you were doing.
- Fraud or intentional misconduct. You cannot disclaim liability for deliberately deceiving someone or causing harm on purpose. Courts treat this as a hard public-policy line.
- Gross negligence. Most jurisdictions will not allow a disclaimer to cover reckless disregard for safety or duty. Where ordinary carelessness ends and gross negligence begins depends heavily on the facts.
- Unconscionable terms. Language buried in a take-it-or-leave-it contract, with terms so one-sided they shock the conscience, can be struck down. Courts look at both the process (did the other side have a meaningful choice?) and the substance (are the terms themselves unfair?).
- Essential public services. Businesses that hold themselves out to serve the general public with vastly superior bargaining power, like hospitals, utilities, and common carriers, face far more scrutiny of any exculpatory clause.
- Regulatory violations. A disclaimer that contradicts a mandatory disclosure can trigger enforcement action in addition to being unenforceable in private litigation.
If you find yourself reaching for a disclaimer to cover conduct you already know is substandard, stop writing and fix the conduct.
Pick the Right Type for Your Situation
Most businesses need two or three disclaimer types working together. The categories below are the ones that come up most often.
Informational and Professional Advice
If you publish content touching law, medicine, finance, or any other licensed field, you need a disclaimer stating that the content is general information and does not create a professional-client relationship. A legal blog should say that nothing on the site constitutes legal advice and that reading it does not form an attorney-client relationship. A health site should say the content does not replace diagnosis or treatment from a licensed provider.
This language matters because licensed professionals owe heightened duties. Without a clear boundary, a reader can argue your content created an implied relationship and that you breached the duty of care that goes with it.
Financial and Investment Content
Content discussing investments, markets, or financial planning should state that it is not personalized financial advice, that decisions should be based on individual circumstances and risk tolerance, and that past performance does not guarantee future results. If you are a registered investment adviser, additional SEC requirements apply, discussed below.
Affiliate and Endorsement Relationships
If you earn money or receive free products from the brands you recommend, federal law requires you to disclose that. The FTC’s endorsement guidelines define a “material connection” as any relationship that could affect the credibility of a recommendation, including payment, free products, family ties, or employment.
The disclosure must be clear, conspicuous, and placed with the endorsement itself, not buried on an “About” page or at the bottom of a long post. Plain language works: “Thanks to [Brand] for the free product” or labeling a post “ad” or “sponsored” is enough when placed prominently. Vague abbreviations like “sp,” “spon,” or “collab” do not meet the standard. In videos, the disclosure belongs inside the video, not just the description. In live streams, repeat it periodically. On image-based platforms, superimpose it over the image long enough to be read.
Content Accuracy
Sites that aggregate information, display user-generated content, or compile third-party data should disclaim responsibility for accuracy. The standard approach states that information is provided “as is,” may contain errors or omissions, and may not reflect the most current developments. This is especially important for directories, review sites, and news aggregators.
Warranty Disclaimers If You Sell Products
Sellers face rules that catch people off guard. Under the Uniform Commercial Code, adopted in some form in nearly every state, every sale of goods comes with implied warranties, including that the product is fit for its ordinary purpose (merchantability) and in some cases fit for the buyer’s particular purpose. You can disclaim these, but only if you follow the rules exactly.
To disclaim the implied warranty of merchantability, your language must use the word “merchantability,” and if the disclaimer is written, it must be conspicuous: visually standing out through capitalization, contrasting font, or similar formatting. Alternatively, selling with language like “as is” or “with all faults” excludes all implied warranties without needing to name them, as long as the language makes plain to the buyer that there is no warranty.
Here is the trap. The federal Magnuson-Moss Warranty Act prohibits you from disclaiming implied warranties if you offer any written warranty on the product. If your product comes with a written promise, even a limited 90-day warranty, you cannot simultaneously tell buyers there is no implied warranty of merchantability. You can limit the duration of implied warranties to match the length of your written warranty, but only if the limitation is reasonable, clearly stated, and prominently displayed on the face of the warranty document. A disclaimer that violates Magnuson-Moss is unenforceable under both federal and state law.
Industries Where the Exact Words Are Required
Some federal agencies mandate specific wording. Using your own version instead of the required language can trigger enforcement regardless of intent.
Dietary Supplements
If you sell a dietary supplement and make any claim about how it affects the body’s structure or function, FDA rules require this exact label disclaimer: “This statement has not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure, or prevent any disease.” It must appear in boldface, displayed prominently, and linked to each structure-or-function claim either by placement next to the claim or by a symbol such as an asterisk. The FDA has said it does not intend to exercise enforcement discretion on this.
Registered Investment Advisers
Registered investment advisers must deliver a narrative brochure, Form ADV Part 2A, covering specified disclosures about services, fees, conflicts of interest, and disciplinary history. The SEC prescribes the topics; you do not get to pick them. The brochure must be delivered to clients, and amendments involving disciplinary information must be delivered promptly. You can omit items that do not apply to a particular client, but you cannot skip required disclosures that do apply.
Social Media Endorsements
The FTC’s Guides Concerning Endorsements require that material connections be disclosed clearly and conspicuously whenever the audience would not reasonably expect the connection. A visual disclosure must stand out from surrounding text in size, contrast, and location. An audible disclosure must be delivered at a volume and pace ordinary consumers can easily understand. In interactive media, the disclosure should be unavoidable.
Make It Enforceable: Notice and Consent
A disclaimer nobody sees protects nobody. Enforceability turns on whether you gave the other party reasonable notice and, ideally, got their affirmative consent.
Clickwrap Beats Browsewrap
This is the single most important enforceability factor online. A clickwrap agreement requires users to take an affirmative action, such as checking a box or clicking “I Agree,” before they can proceed. Courts routinely enforce these because consent is unambiguous.
A browsewrap agreement relies on a hyperlink, usually in the footer, that users never need to click or acknowledge. Courts are far more skeptical. The prevailing view is that a conspicuous hyperlink alone is not enough to bind users, and even placing the link near a relevant button does not automatically create constructive notice. Without actual knowledge of the terms, courts generally require both reasonably conspicuous notice and some affirmative action showing assent.
If a disclaimer is important enough to write, it is important enough to present with a checkbox: “I have read and agree to the [Disclaimer/Terms]” before the user completes a purchase, submits a form, or accesses gated content.
Placement
Place disclaimers as close as possible to the claim or content they qualify. The FTC specifically warns that disclosures buried in “terms of use” and similar long agreements are highly unlikely to be read. A disclaimer integral to understanding a claim should not sit behind a hyperlink alone; it belongs on the same page, immediately adjacent.
Size and color matter. Disclaimer text should be at least as large as the text of the claim it qualifies, and should contrast with its background. Labels like “disclaimer,” “more information,” or “fine print” on hyperlinks do not convey the importance of what is behind them.
For content-specific disclaimers, like a “not medical advice” notice on a health article, put the notice directly above or next to the content rather than relying on a single site-wide page. Users arriving from a search engine may never see your homepage.
Accessibility
A disclaimer that part of your audience cannot perceive weakens the “reasonable notice” argument you would need in court. Under a Department of Justice rule applying to state and local government websites, web content must meet the Web Content Accessibility Guidelines Version 2.1 at Level AA. The rule directly binds government entities, but it sets the benchmark courts and regulators increasingly reference for private sites.
In practice, that means a color contrast ratio of at least 4.5:1 against the background for normal-sized text, at least 3:1 for large text, alt text on any image containing disclaimer language, and captions that include spoken disclaimers in videos.
Keep It Current
A disclaimer written three years ago for a business that has since added products, launched an affiliate program, or moved into a regulated service no longer matches reality. Review the language at least annually and update it immediately when any of the following changes:
- New products or services, each of which may add risks the existing language does not address.
- Regulatory changes. Federal agencies revise disclosure rules, and states periodically update consumer protection laws. The FTC’s endorsement guides were substantially revised in 2023.
- Business model changes, including starting to accept affiliate revenue, adding user-generated content, or offering professional consultations.
- Website redesigns, which can quietly move a disclaimer from a visible spot to an invisible one.
Keep every version on file with its effective date. If you ever need to prove what a user agreed to on a particular day, you will need that archive, and version-stamping shows a court you treat the disclaimer as a living document rather than something you set once and forgot.
