eSignature legality
in Luxembourg

In Luxembourg, both Law on Electronic Commerce of August 14, 2000 (E-Commerce Law), and the Regulation (EU) No 910/2014 on electronic identification and trust services for electronic transactions (eIDAS Regulation) recognise electronic signatures.

The EU Directive 2000/31/CE on electronic commerce was transposed into Luxembourg law by the E-Commerce Act, a law that was passed on August 14, 2000. It serves as the basis for the Luxembourg E-commerce framework and lays out the fundamental requirements for the use of electronic signatures, the activities of providers of electronic signature solutions, and the supervision of such providers.

Since using electronic signatures and certificate-based digital signatures fast-tracks and makes contracting procedures easier in the given times, they have become more prevalent in its usage in Luxembourg. The legislations that govern electronic signatures in Luxembourg, in addition to the eIDAS Regulation, are as follows:

In Luxembourg, an electronic signature that satisfies the following conditions is considered to be valid:

The Regulation (EU) No. 910/2014 on electronic Identification and Trust Services for electronic transactions in the internal market (the Regulation) outlines the following three types of electronic signatures in Luxembourg:

A contract signed with a QES is regarded as being equivalent to a contract executed with a handwritten signature in Luxembourg due to the coexistence of the eIDAS Regulation and the provisions of the E-Commerce Law. A QES, therefore, has a presumption of validity and qualifies as an original signature. Advanced electronic signatures (AES) have a lower burden of proof than simple electronic signatures (SES), although both types of contracts may need further proof if they are challenged to demonstrate that they satisfy the requirements of Article 1322-1 of the Civil Code for integrity and validity.

It is pertinent to note that, under the laws of Luxembourg for electronic signatures, the use of a specific type of electronic signature for a particular process is not explicitly required. A QES may, however, be required to be used in certain specific use cases.  Additionally, a QES is the only type of electronic signature that satisfies the legal requirements for some specific type of documents as required by law.

Any type of electronic signature that complies with the requirements of eIDAS may be used in the following types of transactions under the Luxembourg law:
