Law in force since 27 July 2026
Law No. 5-A/2026 of 28 January entered into force on 27 July 2026 (Article 21).
RTRI — Portugal's Transparency Register of Interest Representation: prepare your registration
Portugal's regime on the legitimate representation of interests (representação legítima de interesses) has been in force since 27 July 2026. Enrolment in the RTRI (Registo de Transparência da Representação de Interesses) is mandatory and a condition for hearings with the public bodies covered (Article 8(1) of Law No. 5-A/2026).
rtri.pt is a private registration-support service operated by Audiqcer, Lda. It is not the official register. The RTRI operates under the Assembleia da República (Portuguese Parliament) and registration is public and free of charge (Articles 4 and 13 of Law No. 5-A/2026).
Status of the register
Two dates matter: the law is already in force; the register itself starts operating on a date to be announced in the Diário da República (official gazette) (Article 18(3)).
RTRI start of operation: [to be announced by notice of the Assembleia da República — Article 18(3)]
We monitor the Diário da República daily and update this page once the notice is published.
Professional third-party representatives
Those professionally representing the legitimate interests of third parties must register within 60 days of the RTRI's start of operation (Article 19(2)).
Registration in 5 steps
Enrolment is free of charge and made directly with the Assembleia da República. The demanding work lies before and after that moment:
- 1.
Applicability and category check. Confirming whether your organisation must register and under which of the five categories of Article 13(3);
- 2.
Collection and validation of the mandatory information required by Article 5(1) — identification, clients and interests represented, corporate bodies, income and public or EU support;
- 3.
Preparation of the supporting dossier, since representatives are responsible for the accuracy of the registered content (Article 5(5));
- 4.
Submission of the application [on the platform to be made available by the Assembleia da República];
- 5.
Maintenance. Updates within 30 days and continued compliance (Articles 5(4) and 5(5)).
Who must register
Entities carrying out the legitimate representation of interests, on their own behalf or for third parties, must enrol in the RTRI (Article 13(2)), under one of five categories (Article 13(3)):
- Private social partners and entities with a mandatory-consultation status (parceiros sociais privados e entidades de audição obrigatória) — enrolled automatically and ex officio (Article 13(4));
- Representatives of third-party interests (representantes de interesses de terceiros);
- Representatives of business interests (representantes de interesses empresariais);
- Institutional representatives of collective interests (representantes institucionais de interesses colectivos);
- Other representatives (outros representantes).
Deadline to note: professional third-party representatives must register within 60 days of the RTRI's start of operation (Article 19(2)).
How we help
The official register is free of charge (Article 13(1)); our paid work is the preparation around it. Five services:
Applicability & Category Check (detailed sheet in Portuguese)
A reasoned opinion on whether your organisation is required to enrol in the RTRI and, if so, under which of the five categories of Article 13(3), including the scenario of automatic ex officio enrolment (Article 4(2)). You receive a clear conclusion, the duties attached to your category and a recommended course of action — the safest first step when the obligation is uncertain.
Assisted RTRI Registration (detailed sheet in Portuguese)
Our core end-to-end service: from the applicability check to the submission of the application. We collect and validate every element required by Article 5(1), organise the supporting evidence and manage the process until enrolment is complete, with priority handling for professional third-party representatives facing the 60-day deadline of Article 19(2). One engagement, one accountable team and no loose ends at any stage of the process.
Registration Dossier Preparation (detailed sheet in Portuguese)
For organisations that will submit the application themselves but want the file built professionally. We map each declaration required by Article 5(1) to its supporting evidence — clients, corporate bodies, income, public or EU support — and deliver an organised dossier, ready for submission and defensible afterwards, since representatives answer for the accuracy of the registered content (Article 5(5)). Gaps and inconsistencies are flagged before they become problems.
Register Maintenance & Updates (detailed sheet in Portuguese)
Registration is not a one-off act: any change must be reflected in the register within 30 days (Article 5(4)). We keep a calendar of your registrable events, prepare and lodge each update, and maintain the evidence file that supports continued compliance (Article 5(5)) — so the register always matches reality and deadlines are never missed. A retainer designed for organisations that value predictability.
Registration Toolkit (detailed sheet in Portuguese)
A self-service package for teams that prefer to prepare the registration autonomously: a checklist of the mandatory information under Article 5(1), document templates and a step-by-step guide through the five stages of the process. The most economical route to a well-prepared application, with the option to upgrade to assisted registration at any point. All materials follow the structure of the official requirements.
International organisations
Foreign and international organisations engaging with Portuguese public decision-makers will find English-language guidance and registration support on our dedicated international site.
