And while these were traditionally handled manually, digitization has given way to more efficient electronic signature systems. But not all of them offer the same legal guarantees.<\/p>\n<p>In this guide, we\u2019ll explain whether it\u2019s legal to digitally sign employment contracts with employees, what types of electronic signatures exist, and how to implement a streamlined, frictionless process.<\/p>\n<h2>Is it legal to sign an employee\u2019s employment contract digitally?<\/h2>\n<p>Let\u2019s get to the central question you\u2019re asking yourself\u2014and the one that brought you here:<\/p>\n<blockquote><p>Is it possible to sign employment contracts digitally?<\/p><\/blockquote>\n<p>The short answer: Y<strong>es, it is possible to electronically sign employment contracts with employees, and in fact, it\u2019s recommended<\/strong>.<\/p>\n<p>However, not just any signature will do. Many employees think that simply <strong>inserting an image of a handwritten signature into the employment contract is sufficient<\/strong>. We regret to inform you that this <strong>is not the case<\/strong>. For a digitally signed employment contract to be fully legally valid, it must guarantee two things:<\/p>\n<ol>\n<li>The employee\u2019s identity<\/li>\n<li>The integrity of the document\u2014that is, proving that it has not been altered after signing<\/li>\n<\/ol>\n<h2>Legal Framework for Electronic Signatures on Employment Contracts<\/h2>\n<p>Beyond the technical requirements that an electronic signature must meet, it is worth noting that, at the European level, electronic signatures are governed by the <strong>eIDAS Regulation (No. 910\/2014)<\/strong>, which explicitly states that<strong> their legal effects or admissibility as evidence in court cannot be denied simply because they are digital<\/strong>.<\/p>\n<h2>Types of Electronic Signatures Applied to Labor Relations<\/h2>\n<p>In a context where retaining current talent requires fast, bureaucracy-free processes, waiting days for a new employee to print, sign, scan, and return their contract not only delays the hiring process but also undermines the employee experience.<\/p>\n<p>For this reason, the use of electronic signatures for employment contracts with employees (or any type of <a href=\"https:\/\/www.viafirma.com\/en\/category\/blog-en\/human-resources\/\">human resources<\/a> document) is crucial to avoid penalties, challenges to employment contracts, or issues regarding evidentiary validity in legal proceedings.<\/p>\n<p>The eIDAS Regulation recognizes <a href=\"https:\/\/www.viafirma.com\/en\/faqs\/types-of-electronic-signature\/\"><strong>three levels of electronic signatures<\/strong><\/a>, each with its own characteristics and specific features:<\/p>\n<h3>Simple Electronic Signature for Human Resources<\/h3>\n<p>This is typically the ideal option for <strong>low-criticality documents<\/strong>: a checkbox to accept terms and conditions, a signature drawn with a mouse to request vacation time, or an attendance record.<\/p>\n<p>However, in most cases, a simple electronic signature in Human Resources<strong> is usually insufficient.<\/strong> This is the case, for example, with documents that we want to remain <a href=\"https:\/\/www.viafirma.com\/en\/faqs\/what-is-a-long-lived-signature\/\"><strong>valid over the long term<\/strong><\/a>; a simple electronic signature does not guarantee the signatory\u2019s unique identity or the document\u2019s long-term integrity. Therefore, if an employee denies having signed a document in court or claims that the document\u2019s content has been altered, the company will find itself in a difficult position and will have a hard time proving the document\u2019s authenticity.<\/p>\n<h3>Advanced Electronic Signature for Human Resources<\/h3>\n<p>For its part, the advanced electronic signature is the most recommended option for talent management, as it meets four essential criteria:<\/p>\n<ul>\n<li><strong>It uniquely links the signer<\/strong><\/li>\n<li>It allows for <strong>clear identification of the signer<\/strong><\/li>\n<li>It has been created using <strong>data under the signer\u2019s exclusive control with a high level of trust<\/strong><\/li>\n<li><span style=\"font-size: 16px;\">It is <strong>linked to the document<\/strong> in such a way that <strong>any subsequent modification is detectable<\/strong><\/span><\/li>\n<\/ul>\n<p>This category includes methods such as <a href=\"https:\/\/www.viafirma.com\/en\/documentation\/sms-otp-signature\/\">OTP signature<\/a>s and biometric signatures. If you are looking to hire employees who will work remotely, this is the ideal solution.<\/p>\n<h3>Qualified Electronic Signature for Human Resources<\/h3>\n<p>This represents the <strong>highest level of legal certainty<\/strong>. It is created using a <strong>qualified digital certificate<\/strong> issued by a Certification Authority and a <strong>secure signature creation device<\/strong>. In practice, it has the same legal effect as a handwritten signature and is equivalent to it.<\/p>\n<p>To use it, all signers <strong>must have an active digital certificate<\/strong>, which often creates some friction when hiring certain types of candidates.<\/p>\n<h2><span style=\"font-weight: 400;\">What type of signature should be used in HR documents, depending on the document?<\/span><\/h2>\n<table>\n<tbody>\n<tr>\n<td><b>HH.RR.

The technology you\u2019ll need depends on the type of signature you choose for the document in question: a digital certificate for a qualified signature or <a href=\"https:\/\/www.viafirma.com\/en\/electronic-signatures\/\">electronic signature software<\/a> for an advanced signature.<\/p>\n<h2>Digitize Your Hiring Processes with Full Legal Assurance<\/h2>\n<p>As you\u2019ve seen, signing employment contracts with employees\u2014or using this process in the Human Resources department\u2014is much more than just a tool for<strong> going paperless<\/strong>: it\u2019s the new employee\u2019s first interaction with the company.
