Simple written form
Simple written form generally requires a written text and signature by the party bound, unless valid electronic equivalents are allowed.
Under Swiss law, simple written form requires that the essential content of the declaration be recorded in writing and signed by the person to be bound. The signature identifies the declarant and expresses final approval. The form may apply because the law requires it or because the parties agreed to it. A qualified electronic signature can in many contexts replace a handwritten signature, subject to statutory conditions and exceptions. If the written form is required for validity, absence of a proper signature normally prevents binding effect.
