Electronic signatures have transformed how companies manage contracts and agreements. But despite their widespread adoption across European businesses, many users still have questions about how they work, when they are legally valid, and how they differ from other types of signatures. Confusion about these topics can lead organisations to either underuse electronic signatures (missing out on their efficiency and legal benefits) or to rely on signing methods that provide weaker legal protection than they realise.
At Namirial, as a Qualified Trust Service Provider accredited under eIDAS, we answer these questions every day. Here are the most common questions, and the complete answers.
1. Is Typing My Name and Clicking “Send” a Legally Binding Signature?
Yes, but with important caveats. Under the eIDAS Regulation (EU Regulation No. 910/2014), completing a form with your name and clicking send constitutes a simple electronic signature. It is legally valid as an expression of intent, and Article 25 of eIDAS establishes that no electronic signature can be denied legal effect solely because it is in electronic form.
However, a simple signature offers very limited protection in practice. The fundamental problem is attribution: it is extremely easy for anyone to type another person’s name into a form or click a submit button. In the event of a dispute, if the signer claims they never agreed to the contract, or that the version they signed was different from the version now being enforced; proving that the signature was made by the specific person it represents becomes very challenging.
For genuine legal protection, an advanced electronic signature is strongly recommended for any document of meaningful value. This type of signature is uniquely linked to the signatory, allows the signatory to be identified, and makes any subsequent modification to the document detectable.
Namirial’s advanced electronic signature captures biometric data from the signing gesture, device information, geolocation, IP address, and a qualified timestamp, creating a legally robust audit trail that can be presented as evidence in any EU court and which is cryptographically impossible to falsify.
For the highest stakes (legally regulated transactions, contracts requiring the force of a notarial act, acts with third-party registration requirements) a qualified electronic signature (QES) provides the maximum legal certainty, equivalent to a handwritten signature in all EU Member States.
2. Do You Need to Initial Every Page of a Contract?
With electronic signatures, no. Initialling each page of a paper contract is a traditional practice designed to demonstrate that the signer has read each page and to prevent pages being added, substituted, or removed after signing. An electronic signature eliminates this need entirely, and does so more reliably than manual initialling.
When a document is electronically signed using a qualified platform, the entire document content is protected by a cryptographic hash function. The hash is a mathematical fingerprint of the document that is unique to that exact content. If anything is changed in the document after signing, even a single character, a single space, or a single page swap, the hash of the modified document will be entirely different from the hash recorded at the time of signing, and the verification will fail immediately.
This means that the integrity protection provided by an electronic signature is absolute and mathematically rigorous: it covers every byte of every page simultaneously, with zero possibility of undetected modification. Manual page-by-page initialling, by contrast, is vulnerable to the substitution of individual pages that the initialler has not carefully examined.
The qualified timestamp embedded in every Namirial signature also certifies the exact moment at which the document was signed, making it impossible to falsely claim that a different version of the document was the one actually signed, or to back-date a signature.
3. Is the Electronic Signature Legal in the EU?
Yes. The eIDAS Regulation creates a clear legal foundation for electronic signatures across all 27 EU Member States. Article 25 states explicitly that an electronic signature cannot be denied legal effect or admissibility as evidence in legal proceedings solely on the grounds that it is in electronic form.
Advanced electronic signatures have full legal effect for the vast majority of commercial contracts, and qualified electronic signatures have the same legal effect as handwritten signatures for all purposes in all Member States.
There are a small number of contexts where qualified electronic signatures or specific national formalities are required, certain real estate transactions, specific public administration procedures, and some regulated financial contracts vary by Member State. For these contexts, Namirial’s qualified signature solutions provide the appropriate level of assurance.
For everyday business contracts, employment agreements, commercial contracts, NDAs, service agreements, supplier contracts, HR documentation, an advanced electronic signature provides full legal validity and is the recommended approach.
4. Can I Save My Signature Image and Reuse It?
Technically, you can save an image of your signature, but this significantly weakens the legal protection it provides, to the point of offering almost none.
A saved signature image is simply a JPEG or PNG file. Anyone with access to your computer, email account, or the image file itself can copy it and paste it onto any document they choose. It offers no biometric proof of identity, no record of when or where it was applied, and no cryptographic binding to the specific document. In legal terms, it is equivalent to rubber-stamping your name: it may look like a signature, but it provides no reliable evidence that you personally signed that specific document at that specific time.
For this reason, Namirial does not permit signatures to be stored and reused. Each advanced electronic signature is created fresh at the moment of signing, capturing live biometric data, device information, geolocation, IP address, and a qualified timestamp, making it unique, non-replicable, and cryptographically bound to both the signer and the document. This unique binding is precisely what gives it its legal force.
5. Does My Electronic Signature Need to Look Identical to My Handwritten Signature?
No. The legal validity of an advanced electronic signature does not depend on visual similarity to a handwritten version, or on having any particular visual appearance at all.
What matters legally is the biometric data captured during the signing act: the points that form the trace, the speed, pressure, acceleration, and rhythm of the hand movement. This biometric data is unique to each individual and is the true “signature” from a forensic and legal perspective. The visible shape on screen is simply the by-product of capturing that data.
If a signature is challenged in court, the biometric data can be analysed by a court-appointed handwriting expert, who can compare it against a reference sample made by the same person using the same device, not by comparing the visual shapes, but by analysing the underlying biometric dynamics. This is the same methodology used by forensic graphologists in criminal proceedings worldwide.
This also means that if you sign consistently but your on-screen signature looks slightly different from your usual handwritten version (which is very common, since stylus input on glass feels different from pen on paper), this has no impact on the legal validity of the signature.
6. What Happens to a Document After Signing? Is It Stored Somewhere?
When a document is signed using Namirial’s platform, several things happen simultaneously:
- The completed document is cryptographically sealed with a qualified timestamp
- A complete audit trail (probative document) is generated, recording all evidence collected during the signing process
- The signed document and audit trail are sent automatically to the sender at their registered email address
- The signed document is sent to the signatory for their records
The document can be stored in Namirial’s qualified long-term archiving service, which guarantees its legal validity and retrievability for decades: even after the signing certificates expire, using long-term validation (LTV) technology. This is particularly important for contracts with long durations, regulated retention requirements, or potential future legal significance.
How to Sign a PDF Document Digitally with Namirial
Namirial’s platform allows you to sign PDF documents using all three eIDAS signature levels: Simple, Advanced, and Qualified, with no need to install any software for the signatory. The process is straightforward:
- The sender uploads the document to Namirial’s platform and identifies the signing fields and signatories
- Each signatory receives the document by email with a secure link
- The signatory opens the document on any device: desktop, tablet, or smartphone
- They apply their signature (biometric, OTP, or certificate-based, depending on the configured level)
- The signed document is immediately available to all parties, with full audit trail
Integration via API allows signing to be embedded directly into existing systems, CRM, ERP, HR platforms, document management systems, so that users never need to leave the tools they already work in.
