As if sharing early drafts of a manuscript isn’t hard enough, authors also have to worry about theft and copyright infringement. Fortunately, theft of a manuscript isn’t as common as one may think, but it still happens occasionally, and those stories spread through the writing community like wildfire, so I often have writers ask me if they should ask their beta readers to sign a non-disclosure agreement (NDA). On the surface, it might seem like the safest way to protect your work, but the answer is a little more nuanced.

​Why Some Authors Consider an NDA

Writing a book is a deeply personal—often years-long—investment of time and creativity. Understandably, many authors worry about:

• Idea theft – A fear that someone might take their concept or storyline and publish it first.
• Premature exposure – Concerns that rough drafts could be shared online or discussed publicly in ways that harm the author’s reputation.
• Privacy – If the book includes sensitive or personal subject matter, the author may want added protection.

In these cases, an NDA feels like a safeguard: a legal promise that readers won’t disclose, copy, or misuse the manuscript.

Why NDAs Can Backfire

While the intention is understandable, NDAs with beta readers often introduce more problems than they solve:

• Barrier to participation – Most beta readers are volunteers, often fellow writers or enthusiastic readers. Requiring them to sign a legal document can feel intimidating or transactional, discouraging genuine feedback.
• Limited enforceability – Unless you’re prepared to spend time and money pursuing a breach legally, the NDA may not be practical protection.
• Trust issues – Asking for a contract upfront can signal distrust, which can dampen the collaborative and supportive spirit that beta reading thrives on.

​The Reality: Is Your Work at Risk?

The truth is that outright theft of unpublished manuscripts is very rare. Most people who sign up to be beta readers are doing it because they love books and want to help authors grow. And even if someone did “steal” your plot, execution matters far more than the idea itself—your voice, characters, and unique style can’t be duplicated.

Less formal NDAs

A “handshake clause” is a less formal option that can be as simple as a short paragraph in the header:

This manuscript is being shared with you as a trusted beta reader. By accepting this copy, you agree to keep it private, not share or distribute it, and use it only for the purpose of providing feedback to the author. All rights to the story, characters, and content remain with the author. Thank you for helping make this book stronger!

Or a single sentence in the footer, such as:
​
** Confidential beta copy — not for distribution. ©[Author Name]. All rights reserved. **
​

Alternatives to NDAs

If you still want a measure of protection without the formality of an NDA, you could:

• Vet your beta readers – Choose people you trust, or ask for referrals from fellow authors.
• Set clear expectations – Send a friendly email outlining that the manuscript is private and shouldn’t be shared without permission.
• Use watermarks or personalized copies – Some authors provide PDFs with the reader’s name on them, which discourages unauthorized distribution.

​Adding a watermark to a file is pretty simple and helps protect your work because the watermark will appear faintly in the background of every page, making it clear that the document is private and discouraging unauthorized sharing. Below are instructions on how to add watermarks in a few of the most popular file formats.

​When an NDA Might Make Sense

All that said, there are a few scenarios where an NDA could be appropriate:

• Collaborative projects with co-authors, editors, or ghostwriters where intellectual property is more complex.
• High-profile works under contract with publishers who require confidentiality.
• Sensitive nonfiction involving private stories, research, or interviews.

In these cases, the NDA isn’t about mistrust—it’s part of professional due diligence.

​For most authors sharing a draft with trusted beta readers, an NDA isn’t necessary and can even scare away good help. What matters more is building relationships with readers who respect your work and providing clear communication about expectations.

Think of beta reading less like a legal risk and more like what it is: a partnership in making your book the best it can be.
