E-signature legality · Europe

Is electronic signature legal in Spain?

Yes. As an EU member state, Spain applies the eIDAS Regulation directly: a simple electronic signature is admissible as evidence and cannot be refused just because it is electronic, while a qualified electronic signature (QES) has the same effect as a handwritten one. Most commercial contracts in Spain have no form requirement at all, so an e-signed service agreement, NDA or freelance contract is binding.

The law

  • eIDAS Regulation (EU) No 910/2014, as amended by Regulation (EU) 2024/1183 — Article 25: an electronic signature cannot be denied legal effect solely because it is electronic
  • Ley 6/2020, reguladora de determinados aspectos de los servicios electrónicos de confianza
  • Ley 34/2002 de servicios de la sociedad de la información (LSSI), art. 23 — contracts concluded electronically are valid

What still needs wet ink, a notary or a qualified signature

  • Acts that require a public deed before a notary (escritura pública), including many real estate transactions
  • Family-law and succession acts

Where Clinch fits

Clinch is built for everyday commercial agreements — freelance and agency contracts, statements of work, NDAs, quotes and service agreements — which in Spainneed no special form. Every signature is captured with the signer's explicit consent, and the signed PDF carries an audit trail (name, email, timestamp of every event, hashed IP) plus a SHA-256 fingerprint of the exact document, so anyone can check it was not changed after signing.

It is a simple electronic signature, not a qualified one: for the documents listed above, use the formality the law requires.
