Having a Spanish parent or grandparent can open a route to Spanish citizenship, but descent alone does not guarantee that you qualify. In 2026, Spain’s Ley de Memoria Democrática (Democratic Memory Law) stopped accepting new applications; here we help you identify your route and which processes remain open.
You may have a route to Spanish citizenship if your father or mother was Spanish when you were born, if your parent was originally Spanish and born in Spain, or if a parent or grandparent was originally Spanish and you qualify for a reduced residence period. Applications properly initiated under the Democratic Memory Law can also continue to be processed. These are different legal routes and should not be treated as the same procedure.
Your father or mother was Spanish when you were born, under Article 17
Proving your parentage and your parent’s Spanish citizenship
Depends mainly on registration and documentation
Your father or mother was originally Spanish and born in Spain
Proving the family relationship, your parent’s Spanish citizenship by origin and their birth in Spain
Varies by Civil Registry
Born outside Spain, with a father, mother, grandfather or grandmother originally Spanish
One year of legal, continuous residence in Spain immediately before applying
Residence period plus processing of the application
Certain children and grandchildren covered by Ley 20/2022
Application or appointment requested within the legal deadline
Existing cases continue to be processed
Great-grandparent or earlier Spanish ancestor
Depends on whether an intermediate generation creates a valid route; if not, residence rules may apply
Depends
The first step in understanding how to get Spanish citizenship by descent is therefore identifying the legal basis before collecting documents. A single birth date, change of citizenship or missing generation can alter the result.
Spain’s Ley 20/2022, de Memoria Democrática (Democratic Memory Law) created a temporary right of option for certain descendants of Spaniards. The filing period ended on October 22, 2025. The Spanish Ministry of Foreign Affairs confirms that new applications under this temporary route are no longer accepted. Applicants who correctly requested an appointment within the deadline and received the corresponding proof can still be given an appointment after October 22 to submit their documentation.
Your case does not cease to exist simply because your appointment or final decision falls after October 22, 2025. Keep the confirmation showing that your request was registered within the permitted period. Processing times vary between Spanish consulates in the United States, and the authority may request additional documents or corrections before deciding the case. Díaz & Asociados can review pending cases, requests to correct or complete an application file, delays and potential appeals when there is a legal basis.
The end of the Democratic Memory Law did not close every route connected with Spanish descent. Depending on your family circumstances, you may still:
Already be Spanish by origin.
Have a right to opt for Spanish citizenship under Article 20 of the Spanish Civil Code.
Qualify for the reduced one-year residence period provided for certain descendants in Article 22.2.f.
The Spanish Civil Code provides that a person born outside Spain whose father, mother, grandfather or grandmother was originally Spanish may qualify for citizenship after one year of legal, continuous residence in Spain immediately before applying. That residence route should not be confused with the former Democratic Memory Law.
The Spanish citizenship by descent requirements are different for each legal basis.
Article 17 of the Spanish Civil Code covers cases in which a person is Spanish from birth. If your father or mother was Spanish when you were born and your circumstances fall within the article, the issue may be proving and registering an existing status rather than obtaining citizenship through a discretionary grant.
Article 20 includes, among other cases, people whose father or mother was originally Spanish and born in Spain. This particular right of option is not subject to an age limit.
Article 22.2.f reduces the required residence period to one year for people born outside Spain to a father, mother, grandfather or grandmother who was originally Spanish. The residence must be legal, continuous and immediately prior to the application. You can check the official Ministry of Justice information on citizenship by option and the provisions of the Spanish Civil Code before starting the process.
The exact documentation depends on the route, but establishing a family chain commonly requires:
Not every document automatically requires an apostille or translation. What matters is what the competent Spanish authority requires for the specific procedure.
You do not always need a Spanish citizenship by descent lawyer. If your case involves one generation, your legal status is clear and every certificate is available and consistent, you may be able to handle the process yourself. Legal assistance becomes more useful when the Spanish ancestor is two or three generations back, records from Spain are missing, names or dates differ between documents, your family history crosses several countries, you are unsure whether the case involves origin, option or residence, your Democratic Memory Law case remains unresolved, or a previous application has been refused.
At Díaz & Asociados, we can review your family line remotely before asking you to obtain documents. We identify the legal route, determine which certificates are relevant, check apostille and translation requirements and assess whether representation through a power of attorney is possible for the steps involved. We also work by video call, email and WhatsApp with clients across U.S. time zones and define the scope and cost of the service before starting. A Spanish citizenship by descent lawyer should help determine whether there is a viable case before you invest in a long documentary search. Message us on WhatsApp and tell us who in your family was Spanish, where that person was born and which documents you already have. We will review the route before recommending the next step.
We review your family line remotely first, so you don’t have to spend time traveling.
We check whether translations or apostilles are necessary and represent you through a power of attorney whenever possible.
We adapt to our clients’ schedules, with a fixed quote and no surprises.
Spain’s modern Civil Registry system was introduced in 1871. For ancestors born earlier, civil birth certificates may simply not exist, making parish baptismal records or other historical evidence necessary. Spain’s official historical archives explain the introduction of systematic Civil Registry records in 1871. Other problems are equally common:
These inconsistencies do not always make the case impossible, but they must be explained and supported with appropriate evidence. For Americans whose Spanish connection goes back several generations, reconstructing this documentary chain is often the most demanding part of the case.
There is no official list of surnames that gives someone Spanish citizenship by descent. A surname may suggest Spanish family origins, but it does not prove that a particular ancestor was a Spanish citizen, that citizenship passed through the family or that you qualify under a current legal route.
The confusion partly comes from the former special procedure for Sephardic Jews of Spanish origin. Under that system, surnames could form part of a broader body of evidence used to demonstrate Sephardic origin. That special route is now closed to new applications. If this is relevant to your family, see our separate guide to Spanish citizenship for Sephardic Jews.
We review the differences between Mexican, Puerto Rican or other countries’ certificates, since each requires different handling within the case.
Many Americans with Mexican roots descend from Spaniards who first emigrated to Mexico before later generations moved to the United States. If you are researching Spanish citizenship by Mexican descent, the important question is still whether you can document a qualifying Spanish ancestor and connect each generation through valid certificates. The case may therefore require comparing Spanish, Mexican and U.S. civil records, where names, surnames and registration practices can differ. Having a Spanish surname by itself is not enough.
Puerto Rico requires a different analysis because the island remained under Spanish sovereignty until 1898. The fact that an ancestor was born in Puerto Rico while it was Spanish territory does not automatically mean every present-day descendant has a direct route to Spanish citizenship. Nationality history, dates and the status of the relevant ancestor must be examined. See our separate guide to Spanish citizenship for Puerto Ricans for the rules that apply to these cases.
We first identify whether you qualify for citizenship by origin, by option or the route for grandchildren, since each has different requirements.
We rebuild the chain of birth, marriage and death certificates that prove the relationship between each generation.
We file your case with the Civil Registry, consulate or Ministry of Justice that corresponds to your address and route.
We’re with you wherever you are. We work directly from Spain and communicate with you by video call, so you can explain your case and easily share all your documents remotely. Although we don’t have a physical office in your city, we can carry out actions directly with the Spanish registry and coordinate all the documentation required by the authorities.
The competent authority depends on which legal route applies and where you live. Because the filing authority changes with the legal route, identifying the route should come before deciding where to submit documents.
For an option procedure handled from the United States, the competent Spanish consular Civil Registry may be involved. A Civil Registry is the Spanish public registry responsible for recording events such as births, marriages and citizenship.
Residence-based citizenship is different. You must first complete the required period of legal residence in Spain and then submit the citizenship-by-residence application to the Spanish Ministry of Justice. The current official application fee for citizenship by residence is €104.05. The Ministry notes that this amount can be revised in accordance with applicable budget legislation.
You can check the current fee and official residence information on the Ministry of Justice website. For the full procedural steps, see our separate guide on how to apply for Spanish citizenship.
Common problems include:
An incomplete documentary chain: one generation is not properly linked to the next.
Unresolved discrepancies: names, surnames or dates differ and the inconsistency is not adequately explained.
Incorrect or unusable documentation: a certificate, apostille or translation does not meet the authority’s requirements.
The wrong legal route: the family relationship does not fit the provision under which the application was made.
A missed statutory deadline: an application relied on a temporary route after it had already closed.
One of the most expensive mistakes is building an entire file around a legal route that never applied. Our approach is therefore simple: review the legal basis first and prepare the documentation second.
