eSignature legality summary
As an EU/EEA state, Denmark is governed directly by eIDAS, which sets three signature tiers across the EU and the principle that a signature cannot be denied legal effect merely because it is electronic. Most commercial contracts require no particular form and may be concluded with a simple electronic signature; where local law prescribes a specific written or notarized form, a qualified electronic signature (QES) or wet ink may be required.
Types of permitted electronic signature
eIDAS defines a simple electronic signature (SES); an advanced electronic signature (AES) meeting the Article 26 requirements (uniquely linked to and identifying the signatory, under their sole control, with tamper detection); and a qualified electronic signature (QES) — an AES created with a qualified signature-creation device and a qualified certificate from an EU-listed trust service provider. Only a QES has the legal effect of a handwritten signature across the EU (Art. 25(2)); an SES or AES is admissible under the non-discrimination clause but carries no special evidentiary presumption.
Documents that may be signed electronically
Most commercial agreements — NDAs, vendor and SaaS contracts, procurement, HR, and similar — can be concluded with an electronic signature where no special form is prescribed. A tamper-evident audit trail and identity verification strengthen enforceability.
Use with caution / not typically appropriate
Use a QES wherever Denmark law requires a specific written or notarized form or a higher-assurance signature, and for high-stakes, regulated, or government-facing matters. Denmark’s civil-law formalities determine which documents fall outside electronic signing.
- Wills and succession documents
- Real-property transfers requiring a notarial deed
- Family-law matters (e.g., marriage, divorce, adoption)
- Powers of attorney that require notarization
- Any document national law requires in a specific written or notarial form (which may need a QES or wet ink)
