The eIDAS regulation distinguishes among the following signature levels:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Simple:<\/strong> lacks true identity or integrity controls, often relying merely on an email address or user ID.<\/li>\n\n\n\n<li><strong>Advanced:<\/strong> uniquely linked to the signatory and created using means under their sole control.<\/li>\n\n\n\n<li><strong>Qualified:<\/strong> based on a qualified certificate issued by a Trust Service Provider (QTSP) and created using a Qualified Signature Creation Device (QSCD).<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"titre2\">The importance of a robust technical evidence file<\/h3>\n\n\n\n<p>Only qualified signatures benefit from a <strong>strong legal presumption of reliability<\/strong>. However, recent case law\u00b9 demonstrates that judges increasingly look deeper into the <strong>technical construction of the evidence file<\/strong>. For it to be deemed valid, this file must contain tangible elements such as:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>A clearly structured <strong>audit file<\/strong>,<\/li>\n\n\n\n<li>A <strong><a href=\"https:\/\/evidency.io\/en\/what-is-eidas-certified-timestamping\/\">qualified timestamp<\/a><\/strong> ensuring a legally recognised date,<\/li>\n\n\n\n<li><strong>Explicit documentation of each technical step<\/strong>, avoiding raw, non-interpretable formats like uncommented XML,<\/li>\n\n\n\n<li>Where appropriate, an <strong><a href=\"https:\/\/evidency.io\/en\/electronic-seal-definition-how-it-works-and-benefits-for-businesses\/\">electronic seal from the QTSP<\/a><\/strong> to secure the entire package and confirm the authenticity of the proof provider.<\/li>\n<\/ul>\n\n\n\n<p><strong>Clarity, coherence, and accessibility of the evidence file<\/strong> are now key criteria in judicial evaluation. Opposing parties will increasingly rely on these standards to dispute the validity of a signature.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"titre2\">Integrating timestamping into internal signature systems<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">What is the purpose of a qualified electronic timestamp?<\/h3>\n\n\n\n<p>As defined in Articles 41 and 42 of the eIDAS regulation, a <a href=\"https:\/\/evidency.io\/en\/qualified-timestamping\/\">qualified timestamp<\/a> associates a legally recognised date and time with a file. It ensures that the file has not been modified since the date was affixed, thereby granting the document a <strong>recognised temporal value across the EU<\/strong>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How to enhance the probative value of an electronic signature using a qualified timestamp?<\/h3>\n\n\n\n<p>Some organisations choose to develop their own in-house electronic signature systems to address specific needs, such as:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Controlling user experience (UX\/UI),<\/li>\n\n\n\n<li>Speeding up deployment,<\/li>\n\n\n\n<li>Ensuring seamless integration with proprietary processes or IT systems,<\/li>\n\n\n\n<li>Or reducing costs, as in-house signatures may be less expensive than using an external qualified provider.<\/li>\n<\/ul>\n\n\n\n<p>In these custom systems, adding a qualified timestamp token from a QTSP is an <strong>effective tool to establish the exact date, reinforce integrity, and confer high evidentiary value<\/strong> to the signed document.<\/p>\n\n\n\n<p>Typical use cases include HR document management, internal approval workflows, or online consent collection.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"titre3\">Courts increasingly examine the technical components of electronic evidence<\/h2>\n\n\n\n<p>In 2025, several Courts of Appeal handed down rulings that reflect a <strong>increased level of scrutiny by judges concerning electronic evidence<\/strong>, even when the signature is issued from a qualified trust service provider. The referenced cases\u00b9 mostly involve disputes between established banks or credit institutions and clients who had signed loan agreements. A common thread is the challenge to the <strong>evidentiary value of the <a href=\"https:\/\/evidency.io\/en\/electronic-signature-overview-case-law\/\">electronic signatures<\/a>, including qualified ones<\/strong>, due to <strong>insufficient or unreadable technical documentation<\/strong>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Examples of rulings rejecting the admissibility of electronic signatures<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Court of Appeal of Rouen, 10 April 2025, Case No. 24\/01774: The evidence file was unusable due to lack of comprehensible documentation.<\/li>\n\n\n\n<li>Court of Appeal of Paris, 3 April 2025, Case No. 23\/19316: A mere \u201celectronically signed\u201d mention was deemed insufficient to establish admissibility.<\/li>\n\n\n\n<li>Court of Appeal of Douai, 27 March 2025, Case Nos. 22\/05040 and 22\/05041: The execution certificates were present but failed to identify the signatory with certainty.<\/li>\n\n\n\n<li>Court of Appeal of Riom, 19 March 2025, Case No. 24\/00497: No proof of the integrity of the signed document was provided.<\/li>\n\n\n\n<li>Court of Appeal of Versailles, 29 April 2025, Case No. 24\/04372 and Court of Appeal of Paris, 15 May 2025, Case No. 24\/02375: The technical documentation was incomplete and too complex for judicial assessment.<\/li>\n<\/ul>\n\n\n\n<p>It is essential to <strong>observe all required technical diligence<\/strong> for a signature to be legally qualified, and in the absence of precise guidelines, ensure that documentation is as clear and detailed as possible.<\/p>\n\n\n\n<p>These rulings share a clear message: <strong>judges now demand detailed documentation of the technical processes underlying electronic evidence<\/strong>. They will not hesitate to reject evidence if the procedures used to verify identity and document integrity are not transparently and legibly presented.<\/p>\n\n\n\n<p>This underscores the need to meet all technical diligence standards required for a legally qualified signature. Failure to provide clear descriptions of authentication methods, document validation, or event logging may result in outright rejection of the evidence. A <strong>well-structured evidence file<\/strong> is therefore essential\u2014one that includes a <strong>qualified timestamp for date-certainty<\/strong> and, where applicable, an <a href=\"https:\/\/evidency.io\/en\/electronic-seal-definition-how-it-works-and-benefits-for-businesses\/\">electronic seal<\/a> to ensure long-term integrity.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"titre4\">Best practices to ensure admissibility of electronic signatures: timestamping and sealing<\/h2>\n\n\n\n<p>To enhance the evidentiary strength of an electronic signature and ensure its admissibility in court, several best practices should be followed:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>When developing internal signature systems, associate a <strong>qualified timestamp from a QTSP whenever there is a high risk of dispute<\/strong>.<\/li>\n\n\n\n<li>In all cases, ensure that the evidence file presented in litigation is <strong>clear, comprehensible, and unequivocally linked to the signed document<\/strong>.<\/li>\n\n\n\n<li>Provide a <strong>plain-language explanation of the signature process<\/strong> suitable for a judge who may not be familiar with technical jargon\u2014this should include authentication methods and technical steps taken.<\/li>\n\n\n\n<li>Preferably, <strong>affix a qualified timestamp at each stage of the technical process<\/strong> to certify its timing.<\/li>\n\n\n\n<li>Where relevant, apply an <strong>electronic seal to the evidence file<\/strong> to secure technical elements, guarantee authenticity, and reinforce enforceability of the agreement.<\/li>\n<\/ul>\n\n\n\n<p><strong>Conclusion<\/strong><\/p>\n\n\n\n<p>The debate over the evidentiary value of electronic signatures cannot be reduced to a simple\/advanced\/qualified distinction. It unfolds against a backdrop of case law from the first half of 2025, in which several French Courts of Appeal dismissed electronic signatures due to technical deficiencies in the supporting evidence. These rulings show that judges now systematically examine the structure of the probative file when assessing admissibility.<\/p>\n\n\n\n<p>Furthermore, attaching a qualified timestamp to a non-qualified signature, as defined under the eIDAS regulation, is a simple and cost-effective solution for strengthening its evidentiary value.<\/p>\n\n\n\n<p><\/p>\n\n\n\n<p><\/p>\n\n\n\n<div class=\"wp-block-buttons is-content-justification-center is-layout-flex wp-container-core-buttons-is-layout-16018d1d wp-block-buttons-is-layout-flex\">\n<div class=\"wp-block-button\"><a class=\"wp-block-button__link has-background wp-element-button\" href=\"https:\/\/evidency.io\/en\/contact-evidency\/\" style=\"background-color:#0c0171\">Contact our experts to learn more about our Qualified Timestamping solution<\/a><\/div>\n<\/div>\n\n\n\n<p><\/p>\n\n\n\n<p><\/p>\n\n\n\n<div class=\"wp-block-group is-nowrap is-layout-flex wp-container-core-group-is-layout-ad2f72ca wp-block-group-is-layout-flex\">\n<div class=\"wp-block-group is-layout-constrained wp-block-group-is-layout-constrained\">\n<p>Case law referenced throughout this article:<\/p>\n\n\n\n<p>Court of Appeal of Rouen, 10 April 2025, Case No. 24\/01774<\/p>\n\n\n\n<p>Court of Appeal of Paris, 3 April 2025, Case No. 23\/19316<\/p>\n\n\n\n<p>Court of Appeal of Douai, 27 March 2025, Case Nos. 22\/05040 and 22\/05041<\/p>\n\n\n\n<p>Court of Appeal of Riom, 19 March 2025, Case No. 24\/00497<\/p>\n\n\n\n<p>Court of Appeal of Versailles, 29 April 2025, Case No. 24\/04372<\/p>\n\n\n\n<p>Court of Appeal of Paris, 15 May 2025, Case No. 24\/02375<\/p>\n<\/div>\n<\/div>\n\n\n\n<div style=\"height:50px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<div class=\"wp-block-group is-layout-flow wp-block-group-is-layout-flow\">\n<p><em><strong>Disclaimer<\/strong><\/em><\/p>\n\n\n\n<p>The opinions, presentations, figures and estimates set forth on the website including in the blog are for informational purposes only and should not be construed as legal advice.
