How much legal weight does my e-signature need?

The law distinguishes between the qualified electronic signature (QES), the advanced electronic signature (AES) and the simple electronic signature (SES). The three standards vary in terms of legal weight and are used for different types of documents.

SES: The digital handshake

The one-click solution for everyday documents

The right fit for signing documents with low liability risk It is legally valid for documents where the law does not require a specific form. Typical use cases are information letters, orders and internal documents. Anyone who has an e-mail address can start signing with SES immediately in Helpfordesk.

AES: The pragmatic solution for contracts without formal requirements

Ready for immediate use thanks to lower requirements

The advanced electronic signature (AES) is legally valid for contracts where the law does not require a specific form.
This applies to most types of contracts, such as rental, purchase or mortgage agreements. Anyone who has a mobile phone number or is a member of AES for Business can start signing with AES immediately.

QES: Legally equal to a handwritten signature

The all-round carefree solution for the highest requirements.

The qualified electronic signature (QES) has the same legal validity as signing by hand.
You can use QES to sign contracts with maximum legal weight of your contracts or when the law requires an equivalent to a handwritten signature. The latter applies, for example, to loan or employment agreements with non-competition clause. For signing with QES in Helpfordesk, an identity check is required. You can choose between online identification via video (EU), face-to-face identification (Switzerland) or you can use a verified electronic identity (eID).
