AI-Assisted Legal Review at the Hellenic Cadastre — Cutting a National Backlog by Up to 90%

The Hellenic Cadastre, Greece's public body responsible for land registration, became what its president Stelios Sakaretsos called the country's first public authority to use artificial intelligence in an administrative decision-support role.

The tool, presented by Digital Governance Minister Dimitris Papastergiou and Deputy Minister Konstantinos Kyranakis, reads the natural-language text of a submitted deed, identifies the type of legal act, and checks it against required elements such as tax declarations and ENFIA property-tax filings.

The system hands the reviewing officer a recommendation to approve or reject each submitted deed, with the final decision staying with the human official rather than the AI.

By mid-2026 the Cadastre reported that 310,000 registrable acts had been completed with AI assistance out of roughly 1.1 million completed since 2024. Backlogs of pending cases fell by a reported 80% at the Athens cadastral office and 90% at Thessaloniki's, figures cited in a Greek Court of Audit report and repeated across independent outlets.

The figures come mostly from the Cadastre and government ministries rather than an independent technical audit of the AI system itself, and no error or false-recommendation rate has been published; the acceleration also coincides with a broader digitisation push (600 million archive pages scanned) that is not solely attributable to AI.
