E-signature legality in Slovenia

Slovenija

Slovenia recognises e-signatures under eIDAS and ZEISZ.

The law in plain language

Slovenia's Electronic Identification and Trust Services Act (ZEISZ, 2018) implements eIDAS. Electronic signatures are admissible in Slovenian courts.

Primary framework
eIDAS + Zakon o elektronski identifikaciji in storitvah zaupanja (ZEISZ)
National act
ZEISZ (Electronic Identification and Trust Services Act), 2018

Signature tiers recognised in {country}

Slovenia 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.

SES
Simple Electronic Signature

The baseline — admissible as evidence in court. Suitable for everyday commercial contracts.

AES
Advanced Electronic Signature

SES + a second factor (typically SMS) that uniquely binds the signature to the signer.

QES
Qualified Electronic Signature

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
  • Employment offer letters, onboarding paperwork
  • Independent contractor + freelance engagement letters
  • Quotes, invoices, statements of work
  • Internal HR documents (policy acknowledgements, training)

Still need wet ink

  • Real estate transfers and mortgages (notarisation required)
  • Wills, testaments, and inheritance documents
  • Marriage, divorce, adoption and other family law instruments
  • Some employment-termination documents under national labour law
