Agreements signed with digital signature are just as valid as those on paper and offer greater verifiable security

Legal validity

When your client digitally signs a document with Visma Addo, it is as legally valid as if they had signed on paper. The verifiable security of Visma Addo is even greater.

Proof value of NemID

The NemID solution issues users a digital signature consisting of a private key and a certificate with a public key. The central element in the NemID solution is that only the user has control over the private key, which is protected by a personal access code ("something you know") and a code from a key card with single-use codes ("something you have").

An agreement document signed with the user's private key card therefore contains secure proof that it was the user of that key card who entered the agreement.

As with agreements entered into on paper, there may arise a problem of proof if the digital documents are damaged or deleted.



Proof value of digital signature

In the case of signatures entered directly on a touchscreen or with a mouse, these are equivalent to a signature on paper. The proof value of an agreement signed in this way is therefore fundamentally the same as an agreement signed on paper.

Visma Addo keeps a log recording every transaction made in the solution, so that at any time it is possible to see which email address a document is sent to and when a document has been signed and returned. This gives a greater degree of verifiable security than a physical signature where such data does not exist.

Verifiable security is further increased, as the parties to the agreement receive an email immediately after the signing that confirms the agreement, which gets attached to the email). If the receiver does not respond to this email, it will subsequently be very difficult for this party to convince a court that the agreement was not entered into.
