On the one hand, on November 28th, 2025, parliamentary proceedings began on a draft Organic Law to guarantee multilingualism and the linguistic rights of citizens towards the national institutions. This initiative, presented by 23 members of parliament from the different political groups: Republicano, EH Bildu, EAJ-PNV, Plurinacional Sumar, BNG, and Compromís, aims to ensure that any citizen, regardless of the region, can address any central institution in the co-official language with full legality, whether it be the judiciary, the Constitutional Court, Government Delegations, the Spanish Ombudsman, or any institution dependent on the General State Administration.

The law amends more than fifteen laws and, in order to access jobs or the judicial branch in autonomous communities with their own official language, it is necessary to know the language and, at the same time, public hiring procedures must include linguistic criteria. It also proposes to remove the disproportions of the current model by adapting it to all official languages. Its goal is to ensure the legal value of documents without requiring a translation. The law has only been considered by the plenary session of the Chamber and still has a long way to go in parliament. 

What is more, on January 29th, 2026, the Congress signed an agreement with the Institut d'Estudis Catalans (IEC), the academic institution responsible for safeguarding the Catalan language. The aim is to ensure that legislative initiatives approved by Congress are published and issued in Catalan within a solid framework. 

The IEC, as the body responsible for Catalan regulations, will assist with the standard version of the laws approved by the Congress. It will also provide services for the drafting, translation, and correction of all non-parliamentary documents. IEC president, Teresa Cabré, stated this agreement “strengthens institutional collaboration so that the language has the necessary resources and is used normally in all areas of law and public life.”

To sum up, both the legislative initiative to guarantee multilingualism and the agreement signed with the IEC are examples that allow the Congress of Deputies to advance in the recognition of co-official languages, especially in the case of Catalan. So, the seat of national sovereignty is making gradual but steady progress regarding respect and consolidation of Spain's linguistic diversity.
