In many projects, the same situation repeats itself. A freelancer carries out a job.
A client pays. The file is delivered. And everyone considers the matter settled.
Yet legally, nothing is really secured. Because under copyright law, paying for a service does not mean acquiring the rights to the creation.
This is a common mistake. Many people think that paying an invoice is enough to become the owner of a logo, a website or a visual. In reality, two things need to be distinguished: the medium (the file delivered) and the exploitation rights. Without a contract, only the medium is transferred. The copyright stays with the creator.
For a client to be able to use a creation legally, a copyright assignment contract is essential. This contract sets out precisely which rights are assigned, under what conditions and for what uses. Without this framework, any use may be regarded as unauthorised exploitation — and therefore as infringement.
French law regulates these contracts very strictly. An assignment contract must be in writing and detailed. In particular, it must specify the rights assigned (reproduction, distribution, adaptation), the duration, the territory and the media of exploitation. Without these elements, the assignment may be held invalid or incomplete.
The absence of a contract does not only penalise the creative. It also exposes the client. Without a clear assignment, the client cannot freely use the content, the creator can challenge its use, and a dispute can arise at any time. In some cases, this can even lead to an infringement action.
In 2025, this issue is becoming even more critical. Files circulate quickly.
Content is reused.
Creations are adapted across multiple media. In this context, the absence of a legal framework becomes an operational risk. What used to be a mere formality is becoming a central element of the business relationship.
Ultimately, the assignment contract answers a simple question: who has the right to do what with this content?
But in practice, another question arises: can it be proven?
A contract sets a framework.
But you still need to be able to show when the file was created, when it was sent and how it was used.
The contract remains essential. But it is no longer always enough. Today, legal certainty rests on two pillars: a clear contractual framework and the ability to document the facts.
This is the thinking behind a new generation of tools. By associating a file with a timestamp and a record of sharing, it becomes possible to create proof that can actually be used.
Solutions such as Rightkeeper, for example, make it possible to certify a file as soon as it is created and to track its use over time.
This shift calls for a change. It is no longer enough to deliver a file. You need to structure how it is used. Clarify the rights,
set the terms of use and be able to prove it.
In 2025, not having an assignment contract is no longer a simple oversight. It is a risk. For the creator, who may lose control of their work. For the client, who may be using content without a solid legal basis.
In an environment where content circulates quickly, security no longer rests solely on trust. It rests on what can be formalised… and proven.
