eSignature Switzerland: the short answer

Searched as eSignature Switzerland, electronic signature Switzerland, or "is an e-signature legal in Switzerland", the answer is the same: yes, for ordinary business documents, under Bundesgesetz uber die elektronische Signatur (ZertES, SR 943.03), with Code of Obligations art. 14 para. 2bis. What varies is which documents are carved out and which tier of signature they need, and that is the part worth reading rather than the general rule.

Switzerland sits outside the EU and outside eIDAS, and its rule is stricter than most people expect. Article 14 paragraph 2bis of the Code of Obligations says that a qualified electronic signature with a qualified electronic timestamp is equivalent to a handwritten signature. Nothing below that tier gets that equivalence. The practical consequence is a clean split: contracts that Swiss law requires to be in written form need a qualified Swiss signature from a recognised provider (Swisscom, QuoVadis and the other providers supervised under ZertES), while the very large category of contracts with no form requirement can be concluded any way the parties like, including a simple electronic signature or an exchange of emails. Most commercial agreements are in that second category. Note also that a qualified signature under EU eIDAS is not automatically a qualified signature under ZertES, which catches out companies signing across the border.

What makes an eSignature valid in Switzerland

• For documents requiring written form: a qualified electronic signature plus a qualified electronic timestamp from a ZertES-recognised provider
• For everything else: agreement between the parties, evidenced by the signing act
• Identification of the signer proportionate to the document
• Integrity of the signed content
• Retention that keeps the signature and timestamp verifiable

Where eSignatures are not valid

• Documents requiring written form, unless signed with a ZertES-qualified signature and timestamp
• Suretyship above the statutory threshold, which needs public notarisation
• Wills and inheritance contracts
• Property transfers requiring a public deed

FAQ

Is an EU qualified signature valid in Switzerland?

Not automatically. Switzerland is not in the EU and does not apply eIDAS, so a QES issued under eIDAS does not by itself meet article 14 paragraph 2bis of the Code of Obligations. For a Swiss document requiring written form, use a provider recognised under ZertES. For a document with no form requirement, this does not arise.

Which Swiss contracts require written form?

A minority, but an important one: consumer credit, certain employment provisions such as non-competes, assignment of claims, and suretyship among them. Most commercial supply, service and NDA agreements have no form requirement at all and can be signed electronically without a qualified signature.

Does Switzerland accept a drawn signature on a PDF?

For a contract with no form requirement, the parties can agree however they like, and a drawn signature with an audit trail is good evidence of that agreement. It is not equivalent to a handwritten signature in the article 14 sense, so it does not rescue a document that legally needs written form.

What PDF Verified is, and what it is not

Electronic signature law is settled in broad terms and specific in the details. The ESIGN Act, UETA, eIDAS and their equivalents recognise electronic signatures across more than 190 countries, and what decides a particular case is intent to sign plus evidence connecting the signature to the signer, which is what the audit certificate records. Certain document types carry their own formalities wherever you are: deeds, wills, some property instruments, and anything requiring a witness or a notary. Sign only what you are authorised to sign, since applying another person signature without their authority is forgery whatever tool is used.

PDF Verified is a tool for preparing, signing, stamping and checking documents. It is not a law firm, a compliance service or a forensic examiner, and nothing here is legal, financial or compliance advice. Requirements differ by country, by document type and by the party asking, so check what applies to your document before you rely on it, and take advice where the document matters. You are responsible for the documents you create, sign and send, and for having the authority to do so: signing or stamping in somebody else name, or as an organisation you do not represent, is forgery whatever tool is used. To the extent the law allows, we accept no liability for how a document made with this tool is used or relied on. The full position is in our terms of service.
