Law 3/2026: Changes to the Legal Framework of Arán for Businesses and Administration

Key data

If your business operates in the territory of Arán or maintains relations with its local administration, the regulatory framework governing those relations has just changed. Ley 3/2026, de 12 de marzo, amends the consolidated text of the Ley municipal y de régimen local de Cataluña to update the legal framework applicable to the territory of Arán, a territory with a historically recognised singular status.

The regulation entered into force on 12 March 2026, although it was published in the BOE on 4 April 2026. This means the changes are already applicable and that any procedure or process with the local Aranese administration must comply with the new framework.

What does this regulation establish?

Law 3/2026 amends the consolidated text of the Ley municipal y de régimen local de Cataluña in the aspects that regulate the functioning of the territory of Arán. The three main pillars of the reform are:

• Institutional organisation: The provisions governing the structure and functioning of the Conselh Generau d'Aran as a specific territorial entity are updated.
• Distribution of competences: The allocation of competences between the Conselh Generau d'Aran and the Aranese municipalities is adjusted, which may affect which body is the valid interlocutor for certain procedures.
• Relations with the Generalitat: The institutional relations between the Conselh Generau d'Aran and the Generalitat de Cataluña are updated.

The Conselh Generau d'Aran is the territorial entity that governs the territory of Arán, a Pyrenean region with a historically recognised singular status, which includes the recognition of Aranese as its own language. This singularity justifies a differentiated legal framework within the Catalan local legislation.

Economic and operational impact

This reform does not introduce new fees or direct financial penalties for businesses or citizens. Its impact is primarily operational and procedural: it changes who has competence to resolve certain procedures and how the different administrations in the territory relate to one another.

For businesses established in Arán, the most relevant practical effects are:

• Possible changes in the competent body for processing local licences, authorisations or administrative procedures.
• Updated relations between the Conselh Generau d'Aran and the Aranese town councils, which may affect the processing chain for files and proceedings.
• The need to verify which administration to approach for certain matters that previously fell under one body and may now fall under another.

For the local administrations in the territory, the reform represents an update to the regulatory framework governing their day-to-day activity, with possible implications for their internal procedures and the management of their institutional relations.

Who is affected?

• Conselh Generau d'Aran: Directly affected entity, with changes to its institutional organisation, competences and relations with the Generalitat.
• Aranese municipalities: Affected by the redistribution of competences with the Conselh Generau d'Aran.
• Businesses established in Arán: Must review which body they should approach for their local administrative procedures.
• Citizens of the territory of Arán: Their relations with the local administration are subject to the new competential framework.
• Administration of the Generalitat de Cataluña: Affected in its institutional relations with the Conselh Generau d'Aran.

Practical example

A construction company operating in the Valle de Arán that needs to apply for a building permit in an Aranese municipality must verify, following the entry into force of Law 3/2026, whether the competence to resolve that permit still lies with the municipal council or whether, as a result of the redistribution of competences between the Conselh Generau d'Aran and the municipalities, the administrative interlocutor has changed.

Similarly, a business that previously dealt with the Conselh Generau d'Aran for certain authorisations must check whether those competences have been maintained, expanded or transferred to the Aranese municipalities. Approaching the wrong body may result in delays in processing and the need to restart procedures before the correct administration.

What should businesses do now?

1. Identify active procedures with the local Aranese administration: Review which procedures, licences or authorisations your business currently has in progress before the Conselh Generau d'Aran or the Aranese municipalities.
2. Verify the competent body after the reform: Check whether the redistribution of competences between the Conselh and the municipalities affects the identified procedures and which body they should now be directed to.
3. Update administrative contacts: If competence has shifted to a different body, update your company's contacts and internal procedures to correctly direct future dealings.
4. Consult the full text of Law 3/2026: Review the specific amendments introduced into the consolidated text of the Ley municipal y de régimen local de Cataluña to identify whether any of them specifically affect your activity.
5. Seek advice if procedures are ongoing: If you have open files with the local Aranese administration, consult a specialist in Catalan local law to ensure the procedure follows the correct course after the reform.
