The electronic signature has become the new standard for validation in the business world. Whether it involves commercial contracts, HR procedures, or governance decisions, it streamlines communication and speeds up decision-making.
However, despite its widespread adoption, some confusion remains: not all electronic signatures are created equal. While the Civil Code grants it the same probative value as a handwritten signature, this validity is strictly contingent on the ability to identify the signer, guarantee the integrity of the document, and provide proof of consent.
Given recurring questions about the legal validity of a digital document and the risks of disputes, it is essential to understand the nuances of the legal framework. Whether choosing a simple, advanced, or qualified signature, the decision should not be left to chance. Here are the key points for understanding the legal framework in effect in France and selecting the appropriate level of security for each of your documents.
An electronic signature is a cryptographic process (a sequence of numbers) that authenticates the signer and ensures the integrity of the document, just like its handwritten counterpart. (France Num)
A digital signature should therefore enable the recipient of a document to identify the individual or organization that affixed the signature and to ensure that the document has not been altered between the time it was signed and the time it is read.
Therefore, an electronic signature must be:
French law has recognized the legality of electronic signatures since the 2000s. However, it was the European eIDAS Regulation, which took effect on July 1, 2016, that truly established a clear and uniform legal framework for digital signatures.
This regulation aims to simplify and harmonize the use of digital identification and authentication services, ensure their legal certainty, and strengthen digital trust.
Article 25(1) of the European Regulation establishes the principle of non-discrimination, pursuant to which “the legal effect and admissibility of an electronic signature as evidence in legal proceedings may not be denied solely on the grounds that the signature is in electronic form or that it does not meet the requirements for a qualified electronic signature.”
European regulations thus recognize the legal validity and evidentiary value of electronic signatures within the European Union. The regulation is directly applicable in all EU member states, meaning that electronic signatures are a legally valid method in France.
Beyond the eIDAS Regulation, French law specifically recognizes and regulates the legality of electronic signatures:
Consequently, the legal validity of an electronic signature is equivalent to that of a handwritten signature in the eyes of French law.
With a few exceptions, all documents can be signed electronically:
The only restrictions apply to private documents relating to family law and inheritance law, in accordance with Article 1175 of the Civil Code.
Under European law, there are three types of electronic signatures. The level of security and reliability, as well as the conditions for using these signatures, vary from one category to another.
A simple electronic signature is defined by the European regulation as “data in electronic form that is attached to or logically associated with other data in electronic form and that the signatory uses to sign.”(Regulation (EU) No. 910/2014 (eIDAS), Article 3)
This type of signature is used, for example, when scanning a handwritten signature to affix it to an electronic document or when signing an order receipt. There are no specific requirements for this category of signature, making it the signing method with the most limited legal validity. In fact, it does not require a process to verify the signer’s identity or to guarantee the integrity of the signed data.
Although its level of security is limited, the simple electronic signature is the most commonly used type of signature because it is quick and easy to use.
However, the simple signature process can be strengthened and made more reliable by establishing a chain of evidence to address any potential challenge to the signature. This evidence file may consist of elements such as the signer’s email address, the IP address of the computer used to sign the document, and so on.
Under the eIDAS Regulation, an electronic signature is considered advanced when it meets the requirements ofArticle 26:
The advanced electronic signature thus relies on a more reliable identification system that enhances its security. More specifically, this may involve submitting a form of identification on the platform, which allows the service provider to verify the accuracy of the information provided and to authenticate the signature.
This can also be achieved by adding an authentication step using an SMS code received by the signatory, which is required to validate the signature.
The qualified electronic signature is the signature format that offers the highest level of legal and technical security. It is based on a more complex system (Decree No. 2017-1416):
Electronic signatures are legally recognized, but the right choice depends on the document and the level of proof required.
The simple rule: the higher the stakes (amounts involved, governance, potential disputes), the more you need to strengthen the signer’s identification, the document’s integrity, and traceability—up to and including considering a qualified signature if necessary.
