Rechtssicherheit beginnt mit der richtigen Archivierung

Wie sicher sind die digitalen Akten Ihrer Mandanten?

Less risk, more legal certainty

The BRAO, BNotO, and GDPR require comprehensive protection of sensitive documents

Law firms and tax advisors bear a significant responsibility for the secure archiving of confidential client and document data. Regulations such as the BRAO, BNotO, the Notarization Act, and the GDPR require storage that is tamper-proof, traceable, and available in the long term.

Audit-proof archiving as the foundation of legal certainty

For law firms and tax advisors, audit-proof archiving is both a legal requirement and the basis of trust. Confidential documents must be protected over the long term, remain complete, and be available at all times.

Rising data volumes, complex IT structures, and risks posed by data deletion, system errors, or cyberattacks increase the pressure to reliably comply with data protection and retention obligations.

Did you know?

  • Under the BRAO and BNotO, electronic files and documents must be stored in an unaltered, traceable, and permanently accessible manner.
  • The GDPR requires the secure storage of personal data—violations can result in fines of up to €20 million or 4% of annual turnover.
  • Systems with WORM technology—such as FileLock—comply with regulatory requirements like GoBD and SEC 17a (KPMG report available).
Between Professional Duty and Digital Responsibility

Why Audit-Compliant Archiving Is Becoming a Challenge for Law Firms and Tax Accounting Firms

The digital transformation presents law firms, notary offices, and tax accounting firms with the challenge of archiving ever-growing volumes of data and complex document structures in a legally compliant and tamper-proof manner.

Growing volumes of data and complex documents

Law firms and tax consulting firms manage a vast number of documents every day—from contracts, powers of attorney, and legal documents to client correspondence. As digitization advances, the volume of data continues to grow, and with it, the need to archive it.

Ensuring Immutability

Laws and regulations such as the BRAO, BNotO, the Notarization Act, and the GDPR require that electronic files and documents be stored in a way that ensures they are immutable, complete, and traceable. In practice, however, there is often a lack of systems capable of meeting these requirements in a technically tamper-proof manner.

Integration with Existing Specialized Systems

Archiving solutions must integrate seamlessly with existing law firm and tax accounting software. Isolated applications or complicated workflows often lead to data discontinuities and security vulnerabilities, and make it difficult to access data during audits or when continuing client engagements.

Liability Risks and Obligations to Provide Evidence

Improper archiving can not only result in professional disciplinary consequences but also entail civil liability risks. Even unintentional alterations or the loss of electronic documents are considered a violation of retention obligations.

Confidential. Legally sound. Future-proof.
