E-signature legality in Spain
España
Spain recognises e-signatures under eIDAS and Law 6/2020.
The law in plain language
Spain implements eIDAS through Law 6/2020 of 11 November 2020 on electronic trust services. Electronic signatures are admissible in Spanish courts under Article 3 of the law; qualified electronic signatures have the legal force of handwritten signatures.
- Primary framework
- eIDAS + Ley 6/2020 + Código civil Art. 1262
- National act
- Ley 6/2020, de 11 de noviembre, reguladora de determinados aspectos de los servicios electrónicos de confianza
Signature tiers recognised in {country}
Spain recognises the three eIDAS-aligned tiers. The right tier depends on the contract — most B2B documents are fine with SES; AES adds an identity-binding factor; QES carries the legal force of a handwritten signature for documents that require written form.
The baseline — admissible as evidence in court. Suitable for everyday commercial contracts.
SES + a second factor (typically SMS) that uniquely binds the signature to the signer.
AES + a qualified certificate from a Qualified Trust Service Provider. Equivalent to a wet signature.
Routinely signed electronically
- B2B service agreements, SaaS contracts, supplier MSAs
- NDAs, sales orders, partner agreements
