eSignature Legality in the European Union
Electronic signatures are legally recognized across all 27 EU member states under a single regulation: eIDAS (electronic IDentification, Authentication and trust Services). Unlike the U.S. model, eIDAS defines three distinct tiers of signature, and which one you need depends on the transaction.

Governing Law
eIDAS Regulation (EU) No 910/2014
Adopted in 2014, eIDAS created a single legal framework for electronic signatures, seals, timestamps, and identification that's directly applicable across every EU member state, no country-by-country transposition needed. Article 25 of the Regulation is the key provision: it states that an electronic signature cannot be denied legal effect or admissibility as evidence purely because it's in electronic form.
eIDAS 2.0 — Regulation (EU) 2024/1183
Published April 30, 2024 and in force since May 20, 2024, eIDAS 2.0 expands the original framework. Its headline feature is the European Digital Identity Wallet (EUDI Wallet), a government-backed digital ID app that every member state must make available to citizens, residents, and businesses by the end of 2026. The wallet is designed to make Qualified Electronic Signatures dramatically easier to produce, no separate hardware token required, while adding new categories of "qualified trust services" like electronic archiving. Implementation is rolling out progressively through 2026–2027 as member states and the European Commission finalize technical standards.
The Three Tiers of eIDAS Signature
1. Simple Electronic Signature (SES)
Any electronic data attached to or logically associated with other electronic data, and used by the signer to sign. Covers typed names, drawn signatures, and clicked "I Agree" confirmations. Valid for the vast majority of commercial and consumer transactions under Article 25(1).
2. Advanced Electronic Signature (AES)
Must be uniquely linked to the signer, capable of identifying the signer, created using data the signer can control with a high level of confidence, and linked to the signed data such that any later change is detectable.
3. Qualified Electronic Signature (QES)
An AES created by a qualified signature-creation device and backed by a qualified certificate issued by an EU-recognized Qualified Trust Service Provider (QTSP). Under Article 25(2), a QES is granted the same legal effect as a handwritten signature across every member state, the strongest tier available.
Which tier do you need? For most contracts, offer letters, NDAs, and vendor agreements, an SES is legally sufficient. Reach for AES or QES when a specific national law requires it (some real estate, certain financial instruments, or filings with government bodies), or when you want the strongest possible evidentiary weight for a high-value agreement.
When EU eSignatures May Not Be Accepted
eIDAS itself doesn't set exceptions, those come from each member state's national law layered on top. Categories commonly excluded across most EU countries:
- Wills and matters of family and inheritance law
- Documents requiring notarization or involvement of a public authority
- Certain real estate transfers requiring registration
- Documents related to suretyship provided by consumers
- Some contracts requiring court or public register involvement
Because these carve-outs are set nationally, confirm against the specific member state's law before sending a sensitive document, what's excluded in Germany may not be excluded in the Netherlands.
How Inkfree Meets EU Requirements
Inkfree supports Simple Electronic Signatures (SES) under eIDAS Article 25(1), which covers the large majority of business and commercial transactions across the EU:
Tamper-proof audit trail
logs every step of the signing process, supporting the evidentiary weight required if a signature is challenged
OTP and passcode authentication
added identity assurance for higher-value agreements
Certificate of Completion
a permanent record included with every signed document
Advanced Electronic Signatures (AES) and Qualified Electronic Signatures (QES) are on our roadmap for regulated industries that require the higher assurance tiers.

Questions, answered.
Common questions about eSignature legality in the European Union.
Yes, as a Simple Electronic Signature (SES) under eIDAS Article 25(1), which is sufficient for most business and commercial transactions across all 27 member states.
SES is any electronic mark showing intent to sign. AES adds identity-linking and tamper-detection requirements. QES adds a government-recognized certificate and device, giving it the same legal status as a handwritten signature everywhere in the EU. Most everyday business documents only need SES.
The EUDI Wallet is a digital ID app every member state must offer by the end of 2026 under eIDAS 2.0. It's designed to make producing a Qualified Electronic Signature as simple as unlocking your phone. Rollout is progressive through 2026–2027, so requirements will keep evolving, we'll update this page as implementing rules are finalized.
The regulation itself applies uniformly and directly. What varies by country is which documents are excluded from electronic signature entirely (wills, certain notarized acts, etc.), those exceptions come from each country's own national law.
