Yes. Firstly, there are undertakings inherent to the document to be signed or the contracting process (such as deadlines, transfer of signed copy to the signatory, withdrawal slip, etc.). In addition, in terms of evidence, an electronic document will only have a probative value if it is kept in conditions that ensure its integrity. Also, legal or regulatory provisions can prescribe a specific level of signature (advanced or qualified certificate, etc.) depending on the context and/or the document.
