How much legal weight
does my e-singature need?

The law distinguishes between qualified e-signatures (QES)
and advanced e-signatures (AES). The two standards vary in terms of area
of application and legal weight. At Skribble you have the choice.

Evidential value of the AES and the QES

QES: The same legal validity
as signing by hand

The all-round carefree signature for the highest demands

Two hands - One contract is signed by hand and another with a mobile phone.

The qualified electronic signature (QES) is legally equal to the handwritten signature.
You use QES to maximise the legal weight of your contracts or when the law requires it to be in writing. The latter applies, for example, to loan or wage agreements with a competition clause. For signing with QES on Skribble, a prior identity check in personal contact or an e-ID is required.

"An authenticated electronic signature combined with an authenticated time stamp within the meaning of the Federal Act of 18 March 2016 on Electronic Signatures is deemed equivalent to a handwritten signature, subject to any statutory or contractual provision to the contrary."
Article 14 paragraph 2bis of the Swiss Code of Obligations (OR)

AES: The pragmatic solution
for contracts without
formal requirements

Instantly operational thanks to lower requirements

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