At Addo Sign, we’ve always stated that our digital signatures are legally binding. But that’s not just something we say – it’s something that has been proven and confirmed in court.
Across the Nordic countries, contracts signed with Addo Sign have been examined and upheld in legal proceedings. In several court cases, verdicts have confirmed that documents signed via Addo Sign carry full legal weight, meeting all requirements for consent, integrity, and identity verification under both national laws and the EU eIDAS Regulation.
In other words, when you sign with Addo Sign, you’re entering into an agreement that holds the same legal strength as a handwritten signature.
This is not theory. It’s proven legal practice.
What makes a digital signature legally binding?
A digital signature becomes legally binding when it can demonstrate:
- The identity of the signer – verified through secure Nordic eIDs such as MitID, BankID, and similar trusted identity providers.
- The signer’s intent to agree – shown through clear consent at the time of signing.
- The integrity of the document – ensured through advanced cryptographic sealing that prevents any later changes.
- A complete audit trail – providing transparent documentation of every step in the signing process.
Addo Sign’s technology and infrastructure are built around these exact principles – which is why courts across the Nordics have confirmed the validity of documents signed with our solution.
