What is an electronic signature?

An electronic signature means data in electronic form which is attached to or logically associated with other data in electronic form and which is used by the signatory to sign. There are three different electronic signatures according to Regulation (EU) 910/2014, whose difference lies in the burden of proof, but an electronic signature shall not be denied legal effect and admissibility as evidence in legal proceedings solely on the grounds that it is in an electronic form.

In addition to the legality that an electronic signature can have on its own, contractual freedom must be taken into account, that is, the will of the parties to sign or formalize a contract in a certain way.
