E-signature legality in Luxembourg
Lëtzebuerg
Luxembourg recognises e-signatures under eIDAS and the 1987 Civil Code amendments.
The law in plain language
Luxembourg implemented eIDAS through amendments to the Civil Code (1987, revised 2020). Electronic signatures are admissible in Luxembourg courts. LuxTrust is the dominant qualified trust service provider — a public-private partnership offering the national identity smartcard and mobile QES app.
- Primary framework
- eIDAS + Loi du 17 juillet 1987
- National act
- Loi du 17 juillet 1987 modifiée par la loi du 17 juillet 2020 (eIDAS transposition)
Signature tiers recognised in {country}
Luxembourg 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
- 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
