How to Prove You Wrote Your Manuscript Before Sending It
Before a manuscript leaves your hands, export it as a PDF and put a qualified timestamp on that exact file. Do this for each version you send, and keep your earlier drafts. The timestamp fixes, in a way courts across the EU presume accurate, that this text existed on that date; the drafts show you writing it. That covers what most writers actually worry about: a contest, a writing platform, a co-writer or a client later claiming the text, or an earlier version, came from them. It cannot protect a premise or an idea, and nothing can. Here is what to keep, what to timestamp and when.
This is general information, not legal advice for a specific dispute.
First, a realistic view of the risk
Reputable literary agents and publishers do not make a habit of taking manuscripts. They reject far more than they read, and a dispute would cost them more than any book. Similar premises turn up all the time because copyright protects the words you wrote, not the idea behind them. Two novels about a lighthouse keeper who finds a letter are not a copyright problem; the same chapters with the names changed are.
The situations where writers do end up needing evidence of their text and its date are more ordinary:
- a co-writer, ghostwriting client or former partner who says the text, or part of it, is theirs;
- a chapter posted on a writing platform, blog or forum and copied elsewhere;
- competition entries, anthologies and paid manuscript assessments, where a text sits with people you do not know;
- freelance writing delivered before payment;
- an accusation that you copied, which you answer by showing your version came first.
Why the usual habits are weak
| Habit | What it shows | Weak point |
|---|---|---|
| Posting a printout to yourself | A postmark | An envelope can be posted unsealed and filled later; courts give it little weight |
| Emailing the file to yourself | A date in your own mailbox | You control the account and the message |
| File dates on your computer | Created and modified times | Change whenever you copy or re-save; trivially edited |
| Google Docs or Scrivener history | The text growing over time | Excellent for how, but held by a platform or by you |
| Qualified timestamp on a PDF | This exact text existed at this moment, unchanged since | Says nothing on its own about who wrote it; keep the drafts for that |
Version history in Google Docs, Word or Scrivener snapshots is worth keeping for exactly the reason the timestamp is weak: it shows the work being written. The two together answer both questions a dispute asks, when and who.
What to timestamp, step by step
- Export a PDF of the version you are about to send. PDF, not DOCX: re-saving a Word or Pages file rewrites its internal metadata, which changes its fingerprint even if you did not change a word. A PDF you never open in an editor stays byte-for-byte the same.
- Timestamp the PDF. Its SHA-256 fingerprint is calculated in your browser and only the fingerprint is sent, so the text stays with you. Leave the option to store and display the original unticked for unpublished work.
- Timestamp exactly what you send, too. If an agent asks for a synopsis and the first three chapters, timestamp that package as sent. That is the version anyone else had.
- Keep the PDF unchanged next to its certificate, together with the email or form submission that shows where it went.
- Repeat for significant revisions. A first full draft, the version after edits, the submission version. A dated chain of versions is far harder to argue with than one date.
For a large folder of drafts, notes and research, you do not need a certificate per file: you can timestamp a manifest that covers all of them at once.

What the certificate says, and what it does not
- It shows that this exact file existed at the timestamped moment, unchanged since, and that you declared yourself its author. Under Article 41(2) of the EU's eIDAS Regulation, courts presume the date of a qualified timestamp accurate.
- It does not create or record any rights. Under the Berne Convention, copyright arises when you write the work, with no formality. Most countries have no register of works, which is why evidence of the date matters.
- It does not cover your premise, plot idea or title. Those are not protected by copyright in the first place.
- It does not replace a contract. For co-writing and ghostwriting, a short written agreement on who owns what will settle more than any evidence after the fact.
- For the United States, registration with the U.S. Copyright Office is the precondition for suing in federal court. If that is a realistic scenario, see how a timestamp and a U.S. filing fit together.
A note on querying
Do not mention a timestamp, "copyright protected" or legal warnings in a query letter. Agents read that as a writer who expects to be robbed, and it does nothing for your evidence, which works just as well unannounced. Timestamp quietly, send professionally.

Frequently asked questions
Do I need to protect my manuscript before sending it to agents?
Copyright already exists the moment you write it. What you may lack is evidence of your text and its date. Timestamping a PDF of each version you send gives you that quietly, without mentioning it in your query.
Will an agent or publisher steal my book?
It is rare with reputable agents and publishers. The more common situations are disputes with co-writers or clients and copying of chapters posted online. Similar premises are normal and are not copyright infringement.
Should I timestamp the Word file or a PDF?
A PDF. Re-saving a Word or Pages document rewrites internal metadata and changes its fingerprint even with no edits, so the file would no longer match its certificate.
Does poor man's copyright work for manuscripts?
It is weak evidence. An envelope can be posted unsealed and filled later, and the U.S. Copyright Office says it is not a substitute for registration. A qualified timestamp is presumed accurate by EU courts.
Does the timestamp protect my book idea?
No. Copyright covers the text you wrote, not the premise, plot idea or title. The timestamp dates your text.
Is my manuscript uploaded?
No. The fingerprint is calculated in your browser and only the fingerprint is sent, unless you choose to store a copy of the file.
