Judges, lawyers, notaries, courts and tribunals give the highest importance to the reliability of legal documents. In the absence of reliable solutions, the legal community and the courts still depend on paper.

Thanks to CertifiO, the trusted digital signature by Notarius, it is possible to ensure the legal reliability of an electronic document and confirm the identity and professional status of the signatory at the time of signing.

Legal reliability of documents

Lawyers know that the reliability of electronic documents is generally the weakest link in the digital world. CertifiO gives a digitally signed document the status of an original; it has the same legal value as hand-signed paper original.

Documents that are digitally signed with CertifiO become evidence and not just prima facie evidence. They are authentic in the sense that they incorporate evidence of their origin and integrity. There is no need for external evidence to establish the reliability of the document.

The electronic document as an "original"

CertifiO can create authentic electronic documents that incorporate evidence of their origin and integrity. Such documents do not require external evidence to establish the reliability of the document.

Origin, integrity, authenticity and long-term reliability of documents

CertifiO for Professionals confirms the signatory’s identity and professional status at the precise time of signing, and ensures that the document has not been modified or tampered thereafter. When used with ConsignO Desktop, the solution produces or converts documents to PDF/A standard, increasing their longevity and ensuring that they can be read and validated for decades to come.

Our compliance with the PDF/a-3 standard allows you to attach files of any format, such as audio recordings, videos or other evidence, whose integrity will also be protected by the digital signature.

Increased productivity for professionals

CertifiO for Professionals and ConsignO Desktop give you tangible benefits:

  • Batch signatures: sign dozens of documents in seconds.
  • Batch conversions to PDF/A standard: Ensure the longevity of hundreds of documents in a few clicks.
  • Multiple signatories: End the print /sign /scan routine for every signature! Adding a signatory becomes easy and quick.
