How to prove you created something first (without a solicitor)
Your photo is being used without credit. Your music is circulating under someone else's name. Your writing appears word-for-word on another site. The first question a solicitor will ask: "Do you have proof that this is yours, and that you had it before they did?"

Summary
Copyright arises automatically at the moment of creation — but that's not enough in a dispute. You also need to prove you made it first. Self-emails are almost worthless. Solicitors are expensive. The UK Copyright Service (£35) is legitimate but limited. Blockchain timestamping is instant, permanent, and free for your first 3 certifications.
The problem: having copyright isn't enough
In the UK, copyright arises automatically when you create an original work — no registration required (Copyright, Designs and Patents Act 1988). The moment you take a photo, write a song, or draw a character, you own the copyright.
But when someone publishes your work under their name, the question shifts from "who owns the copyright" to "who can prove they had it first". That's what proof of prior creation means: demonstrating that at a specific point in time, you were already in possession of this work.
The self-email myth
It's the most common advice, and the most overrated. Email send dates can be manipulated on most mail clients. Attachments can be replaced. A digital forensics expert will dismantle it in minutes. Courts regularly dismiss self-emails because they don't withstand technical scrutiny.
The same applies to unverified screenshots, social media posts, and file modification dates on your computer — all falsifiable.
Methods that actually hold up
A solicitor or notary
A witnessed and dated declaration by a solicitor carries real evidential weight. But it costs hundreds of pounds per work, requires appointments, and isn't practical for photographers, musicians, or writers producing dozens of works a year.
UK Copyright Service
The UK Copyright Service offers registration for around £35 per work. It provides a third-party record of the work at the date of registration — useful, but expensive for high volumes, and the record exists only on their private servers (not publicly verifiable).
Blockchain timestamping
Your file never leaves your device — only its unique digital fingerprint (a SHA-256 hash) is sent. That fingerprint is permanently recorded on the Bitcoin blockchain via the OpenTimestamps protocol.
The proof is permanent(the Bitcoin blockchain doesn't expire), publicly verifiable by anyone on opentimestamps.org without going through Incipite, and legally recognised across the EU under eIDAS regulation (Article 41).
Method comparison
| Method | Cost | Duration | Withstands scrutiny? |
|---|---|---|---|
| Self-email | Free | Permanent | ❌ No |
| UK Copyright Service | ~£35 | Private record | ✅ Yes (UK) |
| Solicitor | £200–500+ | Permanent | ✅ Yes |
| Blockchain timestamp | Free / £2.99 | Permanent | ✅ Yes (EU + global) |
How it works in practice
With Incipite, the whole process takes under 3 minutes:
- 1
Drop your file
Photo, MP3, PDF, video, ZIP archive — any format, up to 200 MB free or 2 GB on a paid plan. Your file never leaves your browser.
- 2
Your fingerprint is anchored on Bitcoin
The SHA-256 hash of your file is submitted to the Bitcoin blockchain via OpenTimestamps. The final anchor takes 10–60 minutes (one block confirmation).
- 3
You receive a PDF certificate
The certificate contains your name, the UTC date and time, your file's SHA-256 hash, and the Bitcoin transaction ID. Verifiable on opentimestamps.org.
What if someone has already copied your work?
Gather everything you have: EXIF metadata from original photos, dated cloud backups (iCloud, Google Drive, Lightroom), draft versions with version history, emails showing the work in progress. Going forward, certify before you publish — proof made at creation is worth far more than proof assembled after a dispute.
Certify your next creation in 3 minutes
Free for your first 3 certifications. No credit card required.
Frequently asked questions
Is a self-email valid as legal proof of creation?
No. Email dates can be manipulated and attachments replaced. Courts routinely dismiss self-emails because they don't withstand technical forensic scrutiny.
Is copyright automatic in the UK?
Yes, under the CDPA 1988, copyright arises automatically on creation. But in a dispute you must also prove you created it before the person who copied you.
Is blockchain timestamping recognised by courts?
Yes. Under eIDAS regulation (Article 41), electronic timestamps are legally recognised across the EU. The proof is independently verifiable on opentimestamps.org.
What is the cheapest reliable method?
Blockchain timestamping via Incipite is free for the first 3 certifications, then £2.99 per work. The UK Copyright Service charges £35+ per registration.
What if someone has already copied my work?
Gather EXIF metadata, dated cloud backups, draft versions, emails showing work in progress. Going forward, certify before you publish.
