eSignature law in European Union
Electronic signatures are recognized across all EU member states under Regulation (EU) 910/2014, eIDAS.
Governing law: Regulation (EU) No 910/2014 (eIDAS) (2014)
The eIDAS Regulation (EU 910/2014) creates a single, harmonized framework for electronic signatures across all 27 EU member states. It defines three legally recognized tiers: Simple Electronic Signature (SES), any electronic mark indicating intent; Advanced Electronic Signature (AdES), uniquely linked to and identifies the signer with tamper-evidence; and Qualified Electronic Signature (QES), AdES backed by a Qualified Certificate from a Qualified Trust Service Provider (QTSP). QES is automatically equivalent to a handwritten signature in every member state. SES and AdES are legally admissible but their weight depends on the surrounding evidence, the standard for most commercial contracts. The Regulation also covers electronic seals (for legal persons), timestamps, and electronic registered delivery.
What makes an eSignature valid in European Union
- For SES: any electronic data attached to other data with intent to sign
- For AdES: unique link to signer, signer identification, sole control of signing data, tamper-detection
- For QES: AdES + Qualified Certificate from QTSP + Qualified Signature Creation Device
- Cross-border recognition guaranteed within the EU/EEA
- Non-discrimination: an eSignature cannot be denied legal effect solely because it is electronic
Where eSignatures are not valid
- Documents requiring written form under member-state-specific law (varies by country)
- Certain notarial acts and registry filings (jurisdiction-specific)
- Family-law and inheritance documents in some member states
- Public-administration acts requiring qualified seals
FAQ
Are electronic signatures legal across the EU?
Yes. eIDAS (EU 910/2014) provides uniform legal recognition across all 27 member states, with mutual cross-border validity for QES.
When do I need QES in the EU?
For most commercial contracts SES or AdES is sufficient. QES is required when the law specifically demands qualified form, typically certain real-estate, family-law, and notarial acts.
Can I use a PDF Verified signature in any EU country?
Yes. PDF Verified SES is recognized in every member state under eIDAS Article 25(1). For AdES/QES, we partner with EU-listed QTSPs on Business Plus and Enterprise.
How does eIDAS handle cross-border recognition?
A QES generated in one member state must be recognized as equivalent to a QES in every other member state (Article 25(3)). SES and AdES are admissible but their evidentiary weight depends on member-state procedure.
