Portugal's Lobbying Transparency Framework
A complete explanation, for international readers, of Law No. 5-A/2026 of 28 January (Lei n.º 5-A/2026, de 28 de janeiro) — Portugal's first comprehensive lobbying regulation regime — and of the obligations it creates for national and foreign entities alike.
Context: a first for Portugal
Portugal has adopted its first comprehensive regime regulating lobbying. Law No. 5-A/2026 of 28 January was published in the official gazette (Diário da República), 1st series, Supplement, No. 19, of 28 January 2026, and entered into force 180 days later, on 27 July 2026 (Article 21). The law approves transparency rules for the interaction between private entities and Portuguese public entities and creates a central register of interest representatives operating under the Portuguese Parliament (Assembleia da República).
For international organisations the essential point is in the very first provision: the regime applies to private entities whether national or foreign (Article 1(1)). What matters is not where an organisation is established but whether it represents interests before Portuguese public entities.
What counts as interest representation
The law defines legitimate interest representation (representação legítima de interesses) as activities carried out in accordance with the law with the aim of influencing, directly or indirectly, the preparation or execution of public policies, legislative and regulatory acts, administrative acts or public contracts, as well as the decision-making processes of public entities, whether conducted in one's own name, on behalf of specific groups or in representation of third parties (Article 2(1)).
The included activities are broad (Article 2(2)): contacts with public entities in any form; sending and circulating correspondence, informational material, discussion papers or position papers; organising events, meetings, conferences or other activities promoting the interests represented; and participating in consultations on legislative proposals or other normative acts.
Certain activities are expressly excluded (Article 2(3)): acts reserved exclusively to lawyers (advogados) and solicitors (solicitadores) in the exercise of their forensic mandate; the activities of social partners within social concertation; responses to requests for information from public entities or to individualised invitations; the exercise of procedural rights under the Administrative Procedure Code (Código do Procedimento Administrativo — CPA) and the Public Contracts Code (Código dos Contratos Públicos — CCP); and the right of petition and the filing of complaints or reports without remuneration.
Which public entities are covered
The regime covers eight categories of Portuguese public entities (Article 3(a)–(h)): (a) the Presidency of the Republic; (b) the Assembleia da República; (c) the Government; (d) the self-government bodies of the autonomous regions; (e) the Representatives of the Republic for the autonomous regions; (f) the bodies and services of the direct and indirect administration of the State; (g) the Bank of Portugal, independent administrative entities and regulatory authorities; and (h) the bodies and services of the autonomous, regional and local administration, including their offices and the intermunicipal entities.
The Transparency Register (RTRI)
The centrepiece of the regime is the Transparency Register of Interest Representation (Registo de Transparência da Representação de Interesses — RTRI), a single register operating under the Assembleia da República (Articles 1(1) and 4). The RTRI is public, free of charge and open, made available in free access through the Parliament's portal in machine-readable, searchable and open data formats, with personal data safeguarded under the GDPR — Regulation (EU) 2016/679 (Article 4(4)). There is no fee: official registration costs nothing.
Registrants are organised into five categories (Article 13(3)): (a) private social partners, entities represented on the Economic and Social Council and entities whose consultation is constitutionally or legally mandatory; (b) representatives of third-party interests; (c) representatives of business interests; (d) institutional representatives of collective interests; and (e) other representatives. Entities in category (a) are registered automatically and ex officio (Article 13(4)); everyone else must register themselves. International consultancies and agencies acting for clients will typically fall within category (b).
What the register must contain
The mandatory content of each registration is set out field by field in Article 5(1): identification of the entity and its corporate purpose; the enumeration of clients, interests represented and sectors of activity whenever representation is carried out on behalf of third parties; the members of the governing bodies and the share capital; the person responsible for the representation activity; the annual income derived from that activity; and any subsidies or financial support received from European Union institutions or from public entities. Registered data must be updated within 30 days of the facts that require the update (Article 5(4)).
Rights, duties and transparency mechanisms
Registration brings rights as well as duties. Registered entities may contact public entities, access public buildings under conditions of strict equality and be informed about ongoing public consultations (Article 6). In return, they are bound by a set of duties (Article 7), including the duty to identify themselves, stating their RTRI registration number, before the officeholders they address (Article 7(1)(e)). Entities professionally engaged in representing third-party interests must additionally keep records of their contractual relationships (Article 7(2)).
Access to decision-makers is conditional on registration: entities subject to registration must appear in the RTRI before a hearing (audiência) can be granted (Article 8(1)). Public entities must disclose, at least quarterly, the meetings held with entities listed in the RTRI (Article 8(3)), and each public entity must provide on its website a page listing all ongoing public consultations (Article 9). The law also establishes a legislative footprint (pegada legislativa) mechanism: at the end of the legislative procedure, all consultations and interactions that occurred during the preparatory phase must be identified, with public entities required to create specific footprint mechanisms (Article 10).
Sanctions, cooling-off and the Code of Conduct
Breaches of the duties carry meaningful consequences (Article 11(1)): total or partial suspension of the registration or of the ability to establish institutional contacts for up to 2 years; limitations on the access of natural persons for up to 2 years; and exclusion from participation in public consultation procedures, likewise for up to 2 years. Sanctioning decisions are published on the Parliament's portal (Article 11(2)) and may be challenged before the administrative courts (Article 11(3)). Carrying out interest representation without prior registration, or providing false information, is referred to the Public Prosecution Service (Ministério Público) (Article 11(6)).
The regime also introduces a cooling-off period: holders of political offices and senior public positions, as well as staff and members of their offices, are barred for 3 years from representing interests before the legal person, ministry or body in which they served (Article 12(1)).
A Code of Conduct (Código de Conduta) is annexed to the law and forms an integral part of it, comprising 5 articles; adherence is mandatory for the public entities covered by Article 3 and for registered representatives (Article 15(1)).
Timeline and deadlines
The law has been in force since 27 July 2026 (Article 21). The date on which the RTRI itself starts operating will be announced by a notice published by the Assembleia da República in the Diário da República (Article 18(3)) — [RTRI start-of-operation date to be announced by notice of the Assembleia da República — Article 18(3)]. That notice starts a critical clock: entities professionally engaged in representing third-party interests — the typical position of consultancies and agencies — must register within 60 days of the RTRI beginning operation (Article 19(2)).
A natural question is how the regime compares with the EU's arrangements. [comparison with the EU Transparency Register to be validated against official sources]
