Proving the prior existence of your creations in court
Evidence is also measured by how well it holds up before a judge. Here is what French law admits and what makes a certificate hard to challenge.
Evidentiary value
What the law says, and what holds up in court.
Except where the law states otherwise, evidence may be produced by any means.
Article 1358 of the French Civil Code
Evidence is unrestricted in civil matters
Article 1358 of the French Civil Code provides that, except where the law states otherwise, evidence may be produced by any means. A timestamped certificate is therefore admissible: the judge assesses its probative value (the weight given to it) based on its technical reliability.
What makes a certificate hard to challenge
Fingerprint, independent timestamping, unalterable registry: the mechanics are detailed in "Securing your creations." Before a judge, each of these three elements must be verifiable by a third party.
From evidence file to litigation
Built up as the creation takes shape, the case file is ready to be presented, in the pre-litigation phase (the amicable stage, before any trial) as well as in litigation. It establishes the context of the creation and lets the debate focus on the harm suffered.

Judicial assessment
How a court evaluates timestamped evidence
A digital certificate is assessed like any electronic evidence, against three criteria. Knowing them means building a case file that answers them in advance.
Authenticity and integrity
The judge first checks that the record matches the file presented. That's the whole point of the cryptographic fingerprint mentioned above: the slightest alteration to the file produces a fingerprint that no longer matches the certificate.
Reliability of the process
The judge then examines the mechanism itself: who applies the date, under what standard, with what traceability. A timestamp issued by a recognized independent provider and an entry in a proven public registry provide stronger elements than a private database.
Link to the dispute
A certificate carries weight when it links the fingerprint and the date to an author, chosen at the time of deposit, and to the claimed creation. This link, more than the technology, makes the difference at the hearing.
Overview
The legal framework by country
Texts and rulings that today give evidentiary value to an electronic timestamp or to an entry in a distributed registry.
France
In a fashion design case, the Marseille Judicial Court accepted a secure digital timestamp as proof of prior existence in copyright law, relying on the record rather than the date of a traditional official report by a commissaire de justice (a public officer, formerly known as a huissier de justice). A European first, consistent with the freedom of evidence set out in Article 1358 of the Civil Code.
European Union
The eIDAS Regulation (EU) No 910/2014 (on electronic identification and trust services) prohibits denying the admissibility of an electronic timestamp on the sole ground that it is in electronic form. The 2024 revision extends this to electronic registries.
Italy
Article 8-ter grants distributed-registry timestamps the same legal effect as a recognized electronic timestamp at European level. It was one of the first comprehensive national frameworks on the matter.
China
The Hangzhou Internet Court was the first jurisdiction to admit digital timestamp evidence in an infringement case, a position endorsed the same year by the Supreme People's Court for all Internet courts.
United States
Since 2017, the Federal Rules of Evidence have allowed self-authentication of electronic records. Rule 902(14) specifically covers data identified by a cryptographic fingerprint, exactly what a certificate produces.
Germany & United Kingdom
Both countries apply their general frameworks to digital evidence (§ 371a ZPO in Germany), with case law specific to digital assets and registries still being built.
Arguing the case
Presenting the evidence at the hearing
Three habits our partner lawyers always follow.
Not all judges have technical training. The fingerprint is explained by analogy with a human fingerprint: it identifies one file, and only that one. The registry is presented as a public log kept in its original state. The Ipocamp certificate includes a summary that can be understood without technical expertise.
A date set by an independent network and a long-established, widely replicated public registry carry more weight than a proprietary solution: reliability is judged by track record and by the independence of the process.
The certificate proves existence and integrity at a given date. It works best alongside correspondence, metadata and internal documents that tell the story of the creation's context and ownership (who holds the rights).
