The Lobbying Law (Law 5-A/2026) establishes the first mandatory transparency regime governing interactions between private and public entities. The new regulatory framework requires prior registration, disclosure of contacts, compliance with incompatibility rules, and adherence to a penalty regime. It directly affects how organizations interact with public decision-makers.

Compliance with the new rules on legitimate interest representation becomes mandatory from July 27, 2026.

This guide provides a practical overview of the key issues under the Lobbying Law. Specifically, it addresses the concept of lobbying, the penalty regime, recommendations for risk assessment, and preparation for registration in the Transparency of Interest Representation Register.
