To write a disclaimer for a book, match the language to what you actually wrote: a fiction disclaimer for a novel, a professional-advice disclaimer for non-fiction that touches health, money, or law, a memory-and-privacy disclaimer for a memoir, a fair use note if you quote copyrighted material, and a content warning if the book contains distressing material. Keep it to a few sentences, place it on the copyright page, and tailor it to your specific content rather than pasting a generic template. No law requires a disclaimer, but one is standard practice and useful evidence of your intent if a reader ever claims your book harmed them.
Pick the Disclaimer Type That Fits Your Book
Most books need one or two of the types below, not all of them. Start with the one closest to your content and add others only if they apply.
Fiction
The standard fiction disclaimer tells readers your characters, settings, and events came from your imagination. A workable version:
This is a work of fiction. Names, characters, businesses, places, events, and incidents are either the products of the author’s imagination or used in a fictitious manner. Any resemblance to actual persons, living or dead, or actual events is purely coincidental.
The key phrase is “purely coincidental.” It signals that you did not intend to portray any real person. If your novel draws heavily from a real setting or historical period, add a line noting that while certain locations or historical events are real, the characters and storyline are invented. Aim for honesty about what’s real and what isn’t rather than a blanket denial that anything in the book connects to reality. Readers and courts both see through that.
Non-Fiction and Professional Advice
If your book covers health, finance, law, psychology, fitness, nutrition, or any subject where readers might act on your words, say clearly that the book is informational and not a replacement for a licensed professional. A solid version:
The information in this book is provided for educational and informational purposes only and is not intended as a substitute for the advice of a qualified medical professional [or: financial advisor / attorney / licensed therapist]. Always seek the guidance of a qualified professional with any questions you may have regarding your specific situation. The author and publisher are not responsible for any adverse effects or consequences resulting from the use of any suggestions or information contained in this book.
Swap in the relevant profession. Three elements do the work: stating the content is informational rather than prescriptive, directing readers to consult a professional, and declining responsibility for outcomes. Health books in particular should urge readers to consult their physician before making changes to diet, exercise, or medication.
Memoir
Memoirs sit between fiction and non-fiction. You’re telling a true story filtered through memory, and the standard approach acknowledges that openly:
This book is a memoir. It reflects the author’s present recollections of experiences over time. Some names and identifying characteristics have been changed, some events have been compressed, and some dialogue has been recreated.
If you changed names to protect privacy, say so. If you combined two people into a composite or rearranged the timeline for readability, disclose that too. The disclaimer isn’t an apology for imprecision. It’s a statement that memory is subjective and that you took reasonable steps to protect the people in your story. Changing names and details is smart where a passage could embarrass or harm someone’s reputation, but a disclaimer alone won’t stop a defamation claim if the person is clearly identifiable from context.
Fair Use
If your book quotes song lyrics, excerpts from other books, academic papers, or other copyrighted material, address fair use. Federal copyright law identifies four factors courts weigh in deciding whether a use is fair: the purpose and character of the use, the nature of the copyrighted work, how much was taken relative to the whole, and the effect on the market for the original. No single factor is decisive.1Office of the Law Revision Counsel. 17 USC 107 – Limitations on Exclusive Rights: Fair Use
A fair use disclaimer typically reads:
This book contains excerpts from copyrighted works used under the fair use provisions of United States copyright law. Such material is included for purposes of commentary, criticism, and scholarship. No infringement of copyright is intended, and all excerpts remain the property of their respective copyright holders.
The disclaimer doesn’t determine whether your use qualifies as fair use. That’s a legal conclusion only a court can make. It signals intent and shows you weren’t trying to steal someone’s work. If you’ve quoted three full pages of a bestselling novel, a disclaimer won’t save you. Keep excerpts brief, use them for genuine commentary or criticism, and when in doubt get permission or consult a publishing attorney.
Content Warnings
Content warnings aren’t liability disclaimers, but they set reader expectations before potentially distressing material. If your book contains graphic violence, sexual content, substance abuse depictions, self-harm, or similar material, a brief note helps readers make informed choices.
A short version works: This book contains depictions of [domestic violence / substance abuse / sexual assault] that some readers may find distressing. Place it on the copyright page or on a separate page immediately before the story begins. Specific content areas are more useful than vague language like “mature themes.” Readers who need warnings need them to be specific.
Where to Place It
The copyright page is the standard location. Readers who look for legal information expect to find it on the back of the title page. Place the disclaimer after your copyright notice and “All rights reserved” line, but before printing details or ISBN information.
For books where a specific warning applies only to certain chapters, add a brief note at the beginning of those sections in addition to the main disclaimer. Memoirs sometimes place their disclaimer on a standalone page before the first chapter, giving it slightly more weight than a line buried among copyright details. That works well when the disclaimer is central to how a reader should interpret the whole book.
No legal rule dictates the exact spot. The goal is that a reader encounters the disclaimer before engaging with the content it addresses. Front matter accomplishes this for most books.
What a Disclaimer Can and Cannot Do
A disclaimer establishes that you did not intend your fiction to depict a real person, that your health book was not meant to replace a doctor, or that your memoir reflects subjective memory. If someone sues, well-written language helps demonstrate you acted in good faith and that the reader was warned about the content’s limitations. Courts consider this kind of evidence.
The limits matter just as much. A disclaimer cannot protect you from claims of gross negligence or intentional misconduct. If your cookbook includes a recipe with a dangerously incorrect dosage of an ingredient and someone gets hurt, a boilerplate “not responsible for damages” line won’t help. Courts routinely refuse to enforce liability waivers that attempt to shield against reckless behavior, that are overly broad, or that violate public policy.
A fiction disclaimer won’t protect a roman à clef where every reader in town can identify the real person behind a thinly veiled character. If the character shares a real person’s job, physical description, hometown, and biographical details, no “all persons fictitious” line will convince a jury the resemblance is coincidental. The disclaimer addresses unintentional resemblance. Intentional depiction dressed up as fiction is a different problem.
Disclaimers also cannot override consumer protection law. If you sell a book promising to cure a disease and add a line saying “these statements have not been evaluated,” you’ve still made a potentially actionable claim. The Federal Trade Commission holds authors and publishers to the same advertising standards as anyone else making health or financial claims.
Extra Language for Regulated Topics
Financial and Investment Books
If you write about investing, the Investment Advisers Act of 1940 is relevant. The Act defines “investment adviser” broadly but excludes publishers of bona fide financial publications of general and regular circulation. To qualify for the exclusion, your book must provide general, impersonal analysis rather than advice tailored to individual readers, and it must not serve as a vehicle for managing subscribers’ portfolios or timing recommendations to market events.2Office of the Law Revision Counsel. 15 USC 80b-2 – Definitions
A disclaimer in a financial book should state clearly that the content is general financial education, that it does not constitute personalized investment advice, and that readers should consult a licensed financial advisor before making investment decisions. That language supports your position under the publisher’s exclusion and shows you weren’t holding yourself out as an adviser to individual readers.
Medical and Health Books
Health-related books carry particular risk because readers sometimes treat them as medical guidance. State explicitly that the book does not provide medical advice, that it is not intended to diagnose or treat any condition, and that readers should consult a qualified healthcare provider before acting on anything in it. If your book discusses medications, supplements, or treatment protocols, add a line about not discontinuing prescribed treatments without physician guidance.
Books with External Links
If your book includes URLs pointing to third-party websites, tools, or downloads, add a line disclaiming responsibility for external content. Websites change, go offline, or get acquired. A link that pointed to a helpful resource on publication day might redirect to something else a year later. A brief statement that you have no control over third-party content and do not endorse external sites protects you from guilt-by-association if a linked resource goes sideways.
“As Is” Language
Some publishers include an “as is” disclaimer for informational content, borrowing from product warranty law. Under the Uniform Commercial Code, disclaiming the implied warranty of merchantability requires either using the specific word “merchantability” or selling something explicitly “as is” or “with all faults,” and the disclaimer must be conspicuous, meaning formatted so a reasonable person would notice it.3Legal Information Institute. UCC 2-316 – Exclusion or Modification of Warranties
In practice, this appears as a line stating that the information is provided “as is” without warranty of any kind, express or implied, including warranties of accuracy, completeness, or fitness for a particular purpose. Whether the UCC warranty framework applies to books the way it applies to physical goods is a question courts haven’t answered uniformly, but the language costs nothing to include and may help if someone claims your reference book contained inaccurate data that caused them financial harm.
Drafting Tips
Keep it short. Two to four sentences is ideal for most books. A full-page wall of legal text on your copyright page signals anxiety, not professionalism, and readers skip it anyway.
Write in plain language. If your disclaimer needs a law degree to parse, it’s working against you. The point is communicating clearly to an ordinary reader what your book is and what it isn’t.
Tailor it to your actual content. A cookbook and a true-crime book face different risks and need different language. Use the examples above as starting points and adjust. If your novel is set in a real city but populated with invented characters, say that. If your self-help book draws on personal experience but you’re not a licensed therapist, say that.
For books where the stakes are high (health advice someone might follow literally, financial guidance involving real money, memoirs about identifiable people who might object), spend the money on a publishing attorney’s review. A lawyer who specializes in media or publishing law can review your disclaimer and your manuscript for a few hundred dollars. That’s far less than defending even a frivolous lawsuit.
