Protecting a Manuscript (Book, Screenplay, Comic) Before Sending It to a Publisher or Agent

You just finished a novel, screenplay or graphic novel. You want to send it to a publisher, literary agent or producer. Before you hit "send", a decisive question: do you have a dated proof of your manuscript?

Copyright protects your work from creation. But if someone tomorrow publishes a text suspiciously close to yours, you must prove you had written yours first. Without prior-art proof, your right exists in theory but becomes very hard to defend in practice.

The risk isn't that a reputable publisher steals your manuscript (rare, and reputationally destructive). The risk is leakage: a reader, an assistant, a committee that shares, a parallel project that surfaces 18 months later.

Why specifically protect a manuscript

What copyright protects

Under most copyright laws (US Copyright Act §102, French CPI art. L. 111-1, Berne Convention), the author of an original work enjoys exclusive incorporeal property rights upon creation.

Concretely, what's protected:

• The formalized expression: the text as written, dialogue, narration.
• Detailed characters: name, distinctive traits, narrative arc.
• The specific plot: precise sequence of events, narrative structure.
• The universe: for SF, fantasy, comics — the detailed world-building.

What's not protected

• Ideas alone (e.g., "a detective who solves crimes via blockchain").
• Genres or trends (e.g., a detective novel in the metaverse).
• Public domain elements (mythology, historical facts).
• General narrative techniques (flashback, first-person narration).

Hence the golden rule: the more polished the manuscript, the stronger the proof. A 2-page synopsis is much harder to defend than a complete manuscript.

The 6 methods compared

Detailed method by profile

Novelist (fiction, essay)

Before sending to a publisher or agent:

1. 1
   Finalize a complete V0

   Manuscript completed, proofread, corrected. The more polished, the stronger the proof. Avoid timestamping isolated fragments.
2. 2
   Export to PDF/A

   Durable, archivable format. Also keep the source file (.docx, .odt, .pages) for future editing.
3. 3
   Timestamp version V0

   Via OpenTimestamps (free) or LegalStamp. Keep the .ots file (or equivalent proof) alongside the PDF.
4. 4
   US Copyright Office registration (recommended for US authors)

   $45-65, gives you statutory damages and attorney fees in case of infringement (per 17 USC §412 if registered before infringement or within 3 months of publication).
5. 5
   Document the context

   Project sheet: writing start date, outline, key milestones, final V0. This trail proves your creative process.
6. 6
   Send to the publisher

   With a clear summary email (title, genre, length, date of completion). Keep the acknowledgment of receipt.

Screenwriter (cinema, series, web series)

The WGA Registry (Writers Guild of America, both West and East) remains the US industry standard. Outside the US: SACD in France, DLF in Denmark, etc.

Recommended workflow:

1. Finalize the screenplay (detailed treatment minimum, ideally complete script).
2. Register with WGA (~$25 for non-members) or US Copyright Office ($45-65, stronger legal weight).
3. Double with a blockchain timestamp: WGA keeps a record, but timestamping offers independent verifiability and lifetime validity.
4. Keep successive versions (clearly numbered: V1, V2, V_final).
5. For team projects: a co-writing agreement specifying rights splits.

Graphic novel / comic author

For a comic, two dimensions to protect: the script (text, dialogue) and the artwork (graphic).

• Script: novelist workflow above.
• Final artwork: timestamp each panel in high resolution (TIFF or PNG). See also our guide on protecting photos before publishing.
• Key characters: timestamp detailed character sheets (visual + bio + traits).

Children's / picture book author

If you're both author and illustrator:

• Timestamp the complete storyboard (text + sketches).
• Timestamp the final manuscript + each finalized illustration.
• Keep sources (PSD, AI, Procreate) in addition to exports.

The "send first, protect later" trap

This is the most frequent mistake. Why it can cost dearly:

Typical case: an author sends their manuscript to 12 publishers. Rejection, rejection, rejection. 18 months later, one of those publishers releases a book strangely close to it. The original author wants to act.

Without prior proof to the send date, they must:

1. Reconstitute the chronology via emails (doable but fragile, dates can be challenged).
2. Prove that their manuscript existed in this exact state at send time.
3. Demonstrate substantial similarity, which requires producing the manuscript as originally sent.

With a prior timestamp proof: it all becomes simple. You present the manuscript + the proof dated 15 days before send. The chronology is clear, prior existence undisputed.

During the editorial process: version

A manuscript evolves: editor feedback, rewrites, cuts, additions. Each version can be the subject of a potential separate dispute.

Best practice:

• Timestamp at minimum: V0 (initial send), V_edited (after major revisions), V_final (galley).
• Name clearly: manuscript-title-v0-2026-04-01.pdf.
• Keep editor feedback emails (proof of collaborative process).

For a trilogy or series, timestamp each volume as you go rather than waiting until the end.

Special cases

Co-authoring

• Co-writing contract before starting (rights allocation, signature procedures, decision authority).
• Timestamp the shared version at each milestone.
• Document individual contributions (commits if using a collaborative tool like Google Docs, or versioned exports).

AI-assisted manuscript

If you used AI tools to brainstorm, structure or edit:

• Check the tools' terms of service (who owns generated content?).
• Document your substantial human contribution (US Copyright Office and most EU copyright frameworks do not recognize works "authored" by AI alone).
• Timestamp the final manuscript resulting from your creative work.

Adaptation of an existing work

• Verify rights (public domain? Rights purchased? License?).
• Timestamp your adaptation as a derivative work.
• Keep written authorizations as applicable.

How much it actually costs

For a single manuscript, realistic budget:

The marginal cost of adding a blockchain timestamp to an institutional registration is negligible (< $5, often $0). It's the best security/cost ratio.

Mistakes to avoid

Relying on a single self-sent email → Metadata can be challenged, weak in court. Always double up.

Timestamping a too-light draft → The more complete the manuscript, the more compelling the prior-art proof.

Forgetting to keep intermediate versions → In a dispute over the work's evolution, milestone versions are precious.

Confusing prior-art proof and publishing contract → Timestamping proves creation. The contract governs rights assignment. Two different things.

Not timestamping before pitching a project → A pitch sent to a studio without prior proof exposes you to "creative convergence" risks you can't disprove.

FAQ

Conclusion

Protecting a manuscript isn't about distrusting publishers or agents — it's about protecting against the unpredictable: leaks, committees that share, parallel projects that surface in parallel.

The method fits in three steps: finalize a polished version, timestamp it with an independent trace, keep file + proof + context. For under $100, you neutralize the costliest risk in the author's journey.

LegalStamp is built precisely for this: drag-and-drop interface, blockchain anchoring + eIDAS qualified timestamping, archiving of each version (V0, V_edited, V_final), long-term retention. No CLI, no paperwork — drop the manuscript, get a dated proof in seconds, and send to publishers with peace of mind.
