A freelance illustrator in Lisbon licenses a character design to a studio in Singapore. Neither country requires a qualified electronic signature for that kind of contract, and the two sides never use one. Eighteen months later the studio reuses the character in a second project without paying a further fee, and the illustrator has to show a court, or more likely a mediator, that she made the design first and that the file she is holding up is the same one she sent. No signature dispute is involved. The entire case turns on one question: can she prove when the work existed.
This is the situation most creative and IP disputes actually sit in. The document was never signed because it never needed to be. What decides the outcome is proof of creation, and that proof does not come from a signature at all.
A signature and a timestamp answer different questions
These two concepts get merged in casual conversation, but legally they are not the same tool.
- A signature (simple, advanced, or qualified under ZertES or eIDAS) answers: who agreed to this document, and did they consent to its terms.
- A qualified electronic timestamp answers a different question entirely: did this exact file exist at this exact moment. Under eIDAS Article 41, a qualified timestamp carries a legal presumption of the accuracy of the date and time it indicates, and of the integrity of the data it is attached to.
A copyright dispute is almost always a timestamp question, not a signature question. Nobody is arguing about whether the illustrator consented to a contract. They are arguing about who made the character first. Confusing the two leads people to think that because a document has no signature requirement, it has no way to be proven, which is not true.
Copyright itself does not need a signature or registration
Under the Berne Convention, copyright exists automatically the moment a qualifying work is created, in every one of the treaty's 181 member countries. There is no signature step, no filing step, no fee. The right attaches to the work itself as soon as it takes a fixed form, whether that is a design file, source code, a manuscript, or a photograph.
Because Berne member states recognise each other's authors under Article 5, a work created in one member country carries copyright protection in all the others, without any local registration. This is what makes the right genuinely international, not tied to a single jurisdiction's signature rules or trust-service regime.
What Berne does not give you is evidence. The right exists whether or not you can prove it, but a right you cannot prove is a right you cannot enforce. That gap, between having the right and being able to demonstrate it, is where most disputes are actually decided.
Why the signature framework does not apply here
Qualified electronic signatures exist to solve a narrow, specific problem: certain document types, in certain jurisdictions, must carry proof of identity and consent equivalent to a handwritten signature. Under Swiss law, ZertES Article 11 sets that bar for the document categories where it applies. Under EU law, eIDAS Article 25(2) does the same. Neither of these is about proving when creative work was made. They are about proving who agreed to what.
Most copyright material never passes through that framework at all. A logo, a manuscript, a piece of music, a dataset, a photograph, a software repository, none of these is a contract requiring a signature by default. Waiting for a signature requirement to trigger some kind of protective action means most creative work sits with no evidentiary record until a dispute forces the question, at which point it is too late to create one.
What actually holds up when creation date is disputed
In practice, courts and mediators weigh evidence of creation date on a spectrum of reliability:
- File system metadata and email timestamps are the weakest form. Both can be altered locally, and neither is independently verifiable.
- Self-mailing or third-party cloud storage dates are stronger but still depend on trusting a platform's internal clock and access logs, which were not designed to serve as legal evidence.
- A cryptographic hash of the file, sealed with a qualified electronic timestamp from an accredited Qualified Trust Service Provider (QTSP) is the strongest form available. The hash proves the exact file, byte for byte. The qualified timestamp proves the exact moment, with the legal presumption of accuracy that eIDAS Article 41 provides. Because the underlying right is recognised globally under Berne, this evidence is not limited to a single jurisdiction the way a signature framework can be.
This is also why blockchain timestamps alone are not the same thing as a qualified timestamp. A blockchain entry can show that a hash existed on a given date, but it does not carry a QTSP's regulatory accreditation or the legal presumption that comes with it. It is evidence a court may weigh, not evidence a court is required to presume accurate.
The practical takeaway
If a piece of work does not fall under a qualified signature requirement, that is not a gap in its legal protection, it means the protection was never going to come from a signature in the first place. Copyright already exists automatically under Berne. What is missing, for most creators and companies, is the sealed, timestamped record that turns an automatic right into a provable one, wherever in the world the dispute eventually happens.
