In Switzerland, electronic signatures are used where traditional wet ink signatures are not mandatorily required by the law. In fact, certain electronic signatures have a better admissibility than traditional wet ink signatures owing to the advanced ability to prove the signature’s authenticity. Digital signatures require digital certificates, and are tend to be used less commonly than an electronic signature. This is likely because these signatures require the involvement of a comparatively complex infrastructure with the interaction of a third-party trust service provider.

Paramount Conditions:Paramount Conditions: Existence, Authenticity and Valid Acceptance are three paramount conditions which provide sanctity to electronic signatures under Swiss Laws. a QES along with an authenticated stamp has the same legal validity and admissibility as a handwritten signature.

Legal sanctity of e-signatures and e-documents

Apart from eIDAS regulations that are applicable to all member states of the European Union, there are two main laws covering the utilization of electronic signatures in Switzerland:

Article 2(g) of the FAES specifies that a digital certificate used for a RES or QES must be issued by an authorized organization that gives services in accordance with the requirements set out in the FAES and who is certified by an accredited conformity assessment body. Additionally, a qualified certificate can only be issued to a natural person and must contain a declaration stating that the electronic signature is valid for that document only.

Under Swiss Civil Procedure Code, Swiss courts are free in their appraisal of the evidence presented to them, and there’s no preference by law for different type of evidence. Thus, no signature shall be denied validity or enforceability solely because it is in an electronic form or that it does not meet the requirements for a QES.

However, if a SES or AES is used in a transaction, the onus of demonstrating that the integrity of the content of the document was preserved falls on the signatory. Additionally, while SES, AES, and RES might not be denied legal effect and admissibility as evidence, it doesn’t necessarily mean that it’ll receive identical legal treatment as a handwritten signature. In Switzerland, a QES has the same legal validity and admissibility as a handwritten signature.

Use cases of electronic signature in Switzerland:

The COVID-19 pandemic has radically changed our lifestyles and how one conducts business. Most non-essential companies have established completely remote work setups. This “new normal” has concentrated more attention on electronic means of transactions. The “new normal” in the age of Covid-19 proceeds to facilitate the use of eSignatures.

Documents that cannot be e-signed in Switzerland:

While a QES combined with an authenticated stamp has an identical legal effect as a handwritten signature, a QES may not actually be sufficient to validly conclude a contract where Swiss law requires a qualified written form. Swiss law provides for a variety of mandatory written form requirements that may apply, looking at the scope and content of the contract in question. Thus, it’s recommended to assess the necessity for a handwritten signature on a case-by-case basis, considering the scope and content of the documents in question. Specific use cases that generally require a traditional written signature include:
