A general transparency regime applicable to the legitimate representation of interests (RTRI) has been published for the first time in Portugal.

The administrative sanctions are not particularly severe, and the framework provides for a review after three years, based on a public evaluation.

The new law that establishes a general transparency framework applicable to the legitimate representation of interests was published on 29 January 2026, and this is the first such framework in Portugal. It creates the Transparency Register for the Representation of Interests (Registo de Transparência da Representação de Interesses - "RTRI") at the Assembly of the Republic and implements a binding Code of Conduct for representatives and public entities. The law will enter into force 180 days after publication, with phased implementation and an ex-post evaluation.
