Transfer of information-based services to an electronic environment is the accomplished fact. Some of such services lead to creation of electronic documents that are signed by qualified e-signature and have legal value equal to hand-signed documents. In fact, the documents are created not for private use but for an exchange with the others. The main challenge of the electronic document usage is their interoperability. An electronic document is a dual technical and legal artefact that depends on a national legislation system and “lives” within a national platform of electronic documents. Therefore, an electronic document is not a subject of technical standardization only. The paper introduces a new concept for an electronic document cross-border interoperability solution based on creation of original copies for each national electronic document platform of the document signatories.
