Spanish Citizenship by Descent in 2026: The Door That Just Closed

At a glance

Read this before you spend a euro on Spain, because the picture changed in 2025 and most write-ups have not caught up.

Spain’s big descent route for grandchildren, the Democratic Memory Law (the “Ley de Nietos”), closed on October 22, 2025. It ran for three years, got its one permitted one-year extension, and then ended. The statute allowed only “un ano mas,” one more year, so no further extension is legally possible, and Spanish consulates have shut their application forms. Unless you had already secured an appointment request by the October 2025 cutoff, that door is closed to you now.

The other special route, for Sephardic Jews (Law 12/2015), closed even earlier: no new applications since October 1, 2019.

So what is left for an American in 2026 is narrow and honest:

• If you have a Spanish parent, you are Spanish by origin under Article 17.1.a of the Civil Code, and you register that at the consulate. This is the clean, still-open route.
• If your Spanish ancestry runs through a grandparent and you missed the Memory Law, there is no open special descent door. You are generally looking at the ordinary residence route (living in Spain, usually ten years, two for Ibero-American nationals, which does not include Americans), not a descent claim.

If you have a Spanish parent, read on. If your hook is a grandparent and you did not file before October 2025, this page will save you from chasing a route that no longer exists.

The clean route: a Spanish parent (Article 17.1.a)

The one descent route that is open and simple is parent-to-child. Article 17.1.a of the Civil Code states that “son espanoles de origen los nacidos de padre o madre espanoles”, people born to a Spanish father or mother are Spanish by origin. Being born outside Spain does not matter; what matters is that a parent was a Spanish national when you were born.

Because this is nationality by origin, it is not something you “apply” for so much as document: you register your birth with the Spanish consular Civil Registry and obtain your papers. There is no language test and no residence requirement, because you are not naturalizing, you are recording a nationality you already hold.

The limit is that Article 17.1.a does not, by itself, reach grandchildren. A US-born grandchild of a Spaniard is Spanish under this article only if the parent in between was themselves Spanish at the grandchild’s birth. If the line went dormant, the parent was never Spanish, and the grandchild has no claim under 17.1.a.

The route that closed: the Democratic Memory Law

For a few years, Spain did open a real door for grandchildren, and it is worth understanding because you will still see it promoted as if it were live.

The Democratic Memory Law (Ley 20/2022), through its eighth additional provision, let three groups opt for Spanish nationality by origin:

• Children and grandchildren of people who were originally Spanish and lost or renounced the nationality after suffering exile for political, ideological, belief, or sexual-orientation reasons.
• Children born abroad of Spanish women who lost their nationality by marrying a foreigner before the 1978 Constitution.
• Adult children of those who gained Spanish nationality under this law or under the 2007 Historical Memory Law.

The window opened on October 21, 2022 for two years, with a single one-year extension that the Council of Ministers granted in July 2024, moving the deadline to October 22, 2025. That was the end. The law caps the extension at one year, so an October-2026 window was never available. From October 23, 2025, consulates stopped accepting appointment requests. Only people who lodged a request in time remain in the pipeline to submit their documents.

If you are in that pipeline with a valid appointment receipt, keep your file moving. If you are not, this route is closed.

The Sephardic route: closed since 2019

The 2015 law that let Sephardic Jews (descendants of Jews expelled from Spain in 1492) naturalize on the basis of that heritage was a naturalization window, not open-ended descent, and it is long gone. New applications ended on October 1, 2019. A later deadline into 2021 covered only completing and correcting files already lodged, not new claims. Treat this route as closed.

The honest filter

Open to you: a Spanish parent. That is nationality by origin under Article 17.1.a, registered at the consulate, with your US citizenship kept.

Closed to you: a grandparent hook via the Memory Law if you did not file by October 2025, and the Sephardic route in all cases now. For a grandchild without a timely Memory Law filing, the realistic path to Spain is residence, which is a visa question (see our Spain reality-check and the Non-Lucrative Visa guide), not a descent claim.

There is talk in Spain of a future reform reopening a descent route, but nothing is enacted, so do not plan around it.

FAQ

My grandparent was Spanish. Can I still get citizenship by descent? Almost certainly not through a descent route in 2026, unless you filed under the Democratic Memory Law before it closed on October 22, 2025. That was the special grandchildren window, and it has ended with no further extension legally possible. The general rule (Article 17.1.a) reaches a child of a Spanish parent, not a grandchild, unless the parent in between was also Spanish. If your only hook is a grandparent and you did not file in time, your realistic path to Spain is residence, not descent.

My parent is Spanish. What do I do? You are Spanish by origin under Article 17.1.a, born to a Spanish parent. You register your birth with the Spanish consular Civil Registry and obtain your documents. It is registration of a nationality you already hold, not a naturalization, so there is no language test or residence requirement.

Is the Ley de Nietos (Democratic Memory Law) still open? No. It opened in October 2022, used its single one-year extension, and closed on October 22, 2025. The statute allowed only one extra year, so it cannot be reopened by extension. Only people who secured an appointment request before the cutoff are still in the pipeline.

What about the Sephardic Jewish route? Closed. New applications ended on October 1, 2019. The later 2021 deadline only allowed people to complete files they had already submitted.

Will I lose my US citizenship? For the nationality-by-origin routes (a Spanish parent, or the now-closed Memory Law option), Spain treats you as Spanish “de origen,” and Spaniards by origin are not required to renounce their other nationality. On that basis a US citizen keeps their US passport. We flag this as a well-grounded reading of the “de origen” rule rather than a one-line official promise, so confirm it for your case.

Does a Spanish passport let me work in the EU? Yes. A Spanish passport is an EU passport, with the right to live and work across the EU.

Sources and methodology

The load-bearing rules are sourced to the Boletin Oficial del Estado (the Civil Code and Ley 20/2022) and to official Spanish consular notices, checked 2026-09-11. The decisive fact, that the Democratic Memory Law window closed on October 22, 2025 with no further extension possible, is confirmed against the statutory one-year-extension cap and multiple official consulate closure notices. Two items are flagged in the claim ledger: the absence of an official fee and processing-time figure, and that the “keep your US citizenship” point is an inference from the “de origen” characterization plus Article 23 of the Civil Code.

This is not legal advice

Expat Future is an editorial decision hub, not a law firm or a nationality-services agency. This page explains the shape of Spanish citizenship by descent in 2026, and above all that the main grandchildren window closed in October 2025, so you can tell quickly whether you still have an open route. It is not legal advice, and it has not been reviewed by a qualified Spanish nationality lawyer, so treat it as well-researched information rather than settled advice. Confirm the current rules, and above all your own eligibility, with a Spanish consulate or a qualified lawyer before you spend money or file.
