Claims of an imminent electoral shift from mass naturalizations under the 'ley de nietos' do not match the pace of Spain’s consular system. The route, established under additional provision eight of the Ley de Memoria Democrática, allowed descendants of Spaniards exiled or emigrated during the Civil War and Franco era to apply for nationality. Consulates accepted applications from October 2022 through October 2025. Although 2.4 million people requested appointments to apply, most will not submit their documents before summer 2027. Diplomatic sources have stressed that a request for an appointment “does not yet amount to a nationality grant”; nor does it count as electoral registration. Most cases are expected to remain unresolved well into the next decade, making any impressive impact on upcoming elections highly unlikely.
The scale of the process is clear in figures cited in a parliamentary response by the Spanish government: by 30 April 2026, 2,622,450 applications were associated with the nationality route, while 557,709 approvals had been recorded. The figures measure different stages. An application or appointment request is not necessarily a complete file ready for a decision; applicants may still need to attend appointments and submit documents, after which officials must verify the file before a successful decision is registered. The government cautioned that the gap between applications and approvals cannot automatically be treated as a queue of complete, decision-ready cases. That distinction is basic to assessing claims by the Partido Popular and Vox about rushed naturalizations or an immediate expansion of the electorate.
The basic bottleneck is the overwhelmed consular network, which has struggled to keep up with the surge in applications. Reinforcement measures announced by the Ministry of Foreign Affairs have either not materialized or remain insufficient to speed up the process before the next general elections. The Consulate General of Spain in Buenos Aires shows the scale of the challenge. Between October 2022 and the October 2025 deadline, it received 645,052 requests, more than one-quarter of the worldwide total. By June 2026, 224,334 people had submitted their documents, and about 30,000 cases had been resolved. Those cases amount to roughly 13% of people who had submitted documents and less than 5% of requests received. As El Mundo reported, the documents submitted by the first approximately 230,000 applicants alone weighed 66 tonnes, or about 13.2 million pages.
Under the previous Ley de Memoria Histórica, the Buenos Aires consulate took 13 years to process 60,000 cases; it now faces a workload many times larger. Projections indicate that the consulate will continue collecting documents from people who booked appointments before the October 2025 deadline until at least 2030 or 2031. Appointments are currently scheduled through March next year, with thousands more to be called in the following months. Document collection is only one stage: officials must then verify and assess each file. The process currently results in about 1,800 monthly resolutions, only half of them related to the 'ley de nietos'. At best, around 10,000 new citizens could be added in Buenos Aires before the next elections, but age restrictions and electoral-roll deadlines would make some ineligible to vote.
Nationality approval does not automatically establish eligibility for the overseas electoral roll. After judicial and administrative scrutiny, consulates have been required to identify which newly naturalized citizens meet the factual criterion of being descendants of exiles and provide relevant information to electoral authorities. That requires a separate review of documentary evidence after the nationality decision; every newly registered citizen is not automatically transferred into an eligible voting category. Foreign Minister José Manuel Albares has described the review as a manual examination of applicants’ documents.
By October 2026, 48 Spanish consular offices had reportedly completed all or part of this verification work. Figures attributed to the State Attorney’s Office put the number added to the Censo Electoral de Residentes Ausentes (CERA), Spain’s electoral roll for residents abroad, at 163,020. A further approximately 70,000 registrations had become available to the electoral census authority after the administrative work. Those figures are far below the headline number of applications and reflect the additional steps between seeking access to the nationality process and becoming an identifiable overseas elector. Rosario illustrates the workload: the consulate had about 50,000 nationality cases to process, and its consul, Virella, organized staff to work over a weekend as part of the verification effort.
The process also addresses concerns raised by Madrid’s regional president, Isabel Díaz Ayuso, about the strategic allocation of new voters. New citizens must request their voting district themselves and provide justification and documentation; consular staff cannot simply assign them to basic provinces. Electoral inclusion so depends on nationality approval, the applicable legal criteria and the required registration procedures.
Limited staffing is largely responsible for the slow pace. Of the 100 employees at the Buenos Aires consulate, only about 15 handle civil registry matters, including the 'ley de nietos' and other records covering births, deaths and marriages. From 2022 to 2026, the consular register grew by just 21,293 people, a 6.3% increase. Planned reinforcements include 29 temporary positions, though some may go to staff whose contracts are ending. A digitalization project with the public engineering firm Ineco could eventually speed up processing, but its impact will not be felt before the next elections. Across the system, officials still have to review documents and issue decisions, while civil registration and the separate transmission or verification of electoral information remain necessary.
Recent results do not support the assumption that new overseas voters will favor the left. In the 2023 general elections, the Partido Popular gained a Madrid seat thanks to CERA votes. In the May 2026 elections for the Council of Spanish Residents in Buenos Aires, the PP won a majority of seats, while the PSOE and an independent list trailed. These results show that nationality applications alone cannot establish how newly eligible voters will participate or which political choices they will make.
The General Council of Spanish Citizenship Abroad (CGCEE) has strongly opposed measures that would restrict or complicate voting rights for Spaniards abroad. The CGCEE warns that suspending postal voting, as proposed by Vox, would effectively disenfranchise thousands living far from consulates and embassies, violating constitutional guarantees. The council has also raised concerns about rhetoric questioning the legitimacy of nationality for descendants of exiles and emigrants, emphasizing that citizenship granted under current law is a legitimate right that must be respected.
The 'ley de nietos' is the nationality route established by additional provision eight of the Ley de Memoria Democrática. Applicants had to seek appointments at Spanish consulates, submit documentation and await verification and approval. For electoral purposes, the process continues after the nationality decision: applicants must register, and consulates must verify eligibility for the CERA where required. The application period has ended, but the administrative work continues. The gap between millions of requests, hundreds of thousands of approvals and the smaller number of people identified through electoral verification shows why the feared immediate electoral impact remains, for now, more political narrative than practical reality.
