Spanish and Portuguese Citizenship by Descent in 2026

The main special routes to Spanish and Portuguese citizenship by descent are now closed to new applications but standard rules based on parentage still apply. Understanding the current legal landscape is crucial for anyone hoping to claim Iberian citizenship in 2026.

For decades an Iberian passport has been a coveted prize for those with ancestral ties to Spain or Portugal. It represents a connection to a rich European heritage and crucially provides the benefits of European Union citizenship. However the pathways to acquiring this status have narrowed significantly. In 2026 the landscape looks very different from just a few years ago with the closure of major temporary laws that granted citizenship to vast numbers of descendants. Spain's Democratic Memory Law has ended and so have the routes for descendants of Sephardic Jews in both Spain and Portugal.

This guide explains the situation as it stands today September 2026. We will explore the remaining routes to Spanish and Portuguese citizenship by descent analysing who may still qualify and what the general process involves. We will cover the standard laws of bloodright or 'ius sanguinis' which form the bedrock of nationality law in both countries. While some doors have closed others remain ajar for those who can provide the necessary proof of lineage.

The End of an Era: Closed Ancestry Laws

Before diving into the current rules it is essential to understand the major changes. Both Spain and Portugal offered generous time limited laws to redress historical injustices. These laws have now expired for new applicants.

Spain's Democratic Memory Law (Grandchildren's Law) Spain's Law 20/2022 known as the Democratic Memory Law or 'Grandchildren's Law' created a temporary pathway for descendants of Spaniards who suffered exile during the Spanish Civil War and Franco dictatorship. It opened on 22 October 2022 and was a significant opportunity for children and grandchildren who did not qualify under previous rules. The application window for this law officially closed in October 2025. Spanish consulates are no longer accepting new applications under this provision. It is important to note that applications that were correctly submitted before the deadline will continue to be processed. There is no new law or extension planned.

Sephardic Citizenship Routes Both countries also implemented laws to grant citizenship to descendants of Sephardic Jews who were expelled from the Iberian Peninsula in the late 15th century.

• Spain's Law 12/2015 provided a path for Sephardic descendants to claim Spanish nationality. This law was open for a limited period and is now definitively closed to new applications.
• Portugal's Sephardic route was amended by a new Nationality Law Lei Orgânica n.º 1/2026. As of 19 May 2026 new applications under this special regime are no longer accepted. Applications submitted before this date are being processed under the previous rules which may still involve demonstrating a connection to Portugal.

The closure of these popular routes means that prospective applicants must now look to the standard and more restrictive nationality laws of each country.

Spanish Citizenship by Descent in 2026

With the special laws closed the primary route to Spanish citizenship by descent is through the standard provisions of the Spanish Civil Code. These rules are based on the principle of ius sanguinis meaning citizenship is passed down from a parent to a child.

The fundamental rule is that a person born to a Spanish father or mother is Spanish by origin. This seems simple but the application of this rule has been complicated over the years by various legal changes. Historical laws contained different provisions regarding gender whether parents were married and where the child was born.

Key considerations for a potential claim include:

• A Parent's Spanish Nationality: You must prove that at least one of your parents was a Spanish citizen at the time of your birth. If your Spanish parent naturalised in another country before you were born you may have lost the right to Spanish nationality through them.
• Birth Abroad: For Spaniards born abroad to parents who were also born abroad there can be a risk of losing Spanish nationality. The law has mechanisms to prevent this often requiring a declaration to retain citizenship before the age of 21. The specifics have changed over time so the law in force at the relevant time is what matters.
• Historical Gender Discrimination: Older versions of Spanish nationality law treated transmission from mothers differently than from fathers. While many of these discriminatory provisions have been addressed they can still create complexities for older generations.

Because of this complexity it is impossible to give a simple yes or no answer for eligibility without a detailed analysis of a family's history. The Spanish Ministry of Foreign Affairs is the ultimate authority. You must contact the Spanish consulate or embassy that serves your region to understand the specific requirements for your situation.

For those who do not qualify by descent there are other pathways to a Spanish passport but they involve residing in the country first. You can explore these options in our guide to moving to Spain.

Portuguese Citizenship by Descent in 2026

Portugal's rules for citizenship by descent are also based on ius sanguinis and offer pathways for children and grandchildren of Portuguese citizens. The framework is generally considered more straightforward than Spain's for recent generations.

Citizenship for Children of Portuguese Citizens If you have a Portuguese parent you are generally entitled to Portuguese citizenship. The process is one of 'attribution' which means you are considered to have been Portuguese since birth. The key is to register your foreign birth in the Portuguese civil registry. This process is typically straightforward provided you can supply your parent's Portuguese birth certificate and your own foreign birth certificate. The process can be done at a Portuguese consulate abroad.

Citizenship for Grandchildren of Portuguese Citizens Grandchildren of Portuguese citizens can also acquire citizenship but the process is different. It is a form of 'naturalisation' not 'attribution'. This means you become a citizen from the date of registration not from birth. A crucial requirement for grandchildren is proving an 'effective connection' (ligação efetiva) to the Portuguese community.

The law does not provide an exhaustive list of what constitutes an effective connection. However it is commonly understood to include factors like knowledge of the Portuguese language regular travel to Portugal and ownership of property or business interests there. The brief for this article confirms that A2-level Portuguese language proficiency is one such condition. Proving this connection is a significant hurdle and the assessment is made on a case-by-case basis. You should consult official sources for the latest interpretation of this requirement.

Like Spain Portugal offers other routes to citizenship for those who become residents. You can learn more about visa options in our detailed guide on moving to Portugal.

Why Pursue Iberian Ancestry? The Value of an EU Passport

The drive to secure Spanish or Portuguese citizenship is about more than just a connection to one's roots. The ultimate prize for most applicants is an EU passport. Citizenship of any EU member state grants the holder the status of an EU citizen with a powerful set of rights and benefits.

The most significant benefit is freedom of movement. As an EU citizen you have the right to live work study and retire in any of the 27 EU member states plus Iceland Liechtenstein Norway and Switzerland. This opens up a continent of opportunities for you and your family without the need for visas or work permits.

Other advantages include:

• Access to Education: You can attend universities in any EU country often paying the same lower tuition fees as local students.
• Healthcare Rights: The European Health Insurance Card (EHIC) gives you access to state-provided healthcare during a temporary stay in another EU country. If you move to another member state you will generally have access to its healthcare system on the same basis as its own citizens.
• Consular Protection: If you are in a country outside the EU where your home country (Spain or Portugal) does not have an embassy or consulate you are entitled to consular protection from any other EU member state's diplomatic mission.
• Visa-Free Travel: Spanish and Portuguese passports are among the most powerful in the world granting visa-free or visa-on-arrival access to a vast number of countries globally.

These tangible benefits make the arduous process of documenting one's ancestry a worthwhile endeavour for many. An EU passport is a powerful tool for global mobility and a valuable asset for future generations.

How to Apply for Spanish or Portuguese Citizenship by Descent

The application process is a bureaucratic marathon not a sprint. It demands precision patience and a meticulous approach to documentation. While specific steps vary between countries and consulates a general framework applies to most descent applications.

1. Conduct a Preliminary Family Assessment. Before you spend any money on documents you must build your family tree. Trace your lineage back to your immigrant ancestor. You need to know their full name date of birth place of birth and approximate date of emigration. This initial research will determine if you even have a potential claim.

2. Identify the Correct Legal Pathway. This is the most crucial step. Based on your family history determine which law applies to you. Are you the child of a Portuguese citizen applying for attribution? Or the grandchild needing to prove an effective connection? Is your Spanish claim straightforward or complicated by historical rules on citizenship loss? Misunderstanding the legal basis of your claim is a common reason for failure.

3. Gather the Generational Document Chain. You must create an unbroken paper trail from your ancestor to yourself. This is the core of your application. You will need to obtain long-form certified copies of official records for every person in your direct line.

   • Birth certificates for every generation.
   • Marriage certificates for every couple in the line.
   • Death certificates where applicable.
   • Your ancestor's birth and marriage records from Spain or Portugal.
   • Evidence of your ancestor's non-naturalisation in your home country. This is a critical document to prove they did not voluntarily renounce their original citizenship before their child was born. Alternatively if they did naturalise the date is essential.

4. Ensure Documents Meet Official Standards. Simply having the documents is not enough. They must be in the correct format. Most documents issued outside of Spain or Portugal will need an 'apostille' a form of international authentication under the Hague Convention. All documents not in Spanish or Portuguese must be translated by a sworn translator approved by the respective government.

5. Seek Professional and Official Guidance. Given the complexity especially with older claims seeking professional legal advice is highly recommended. An experienced immigration lawyer can assess your eligibility help you navigate the bureaucracy and identify potential problems before you apply. You must always cross-reference advice with the official requirements listed on the website of the relevant Spanish or Portuguese consulate for your jurisdiction.

6. Submit Your Application File. Applications are usually submitted in person at the consulate or embassy in your country of residence. You will need to book an appointment which can sometimes have a long waiting list. Ensure your file is complete and perfectly organised according to the consulate's checklist. Any missing or incorrect document will cause significant delays.

7. Be Patient. Once submitted the processing time can be very long often taking two years or more. You must be prepared to wait and respond promptly to any requests for additional information. Do not make irreversible life plans based on an expected approval date.

Frequently asked questions

I missed the deadline for Spain's Democratic Memory Law. Are there any exceptions?

No. The application window for Spain's Democratic Memory Law (Law 20/2022) closed in October 2025. There are no provisions for late submissions or exceptions to the deadline. Spanish consulates are no longer accepting new applications under this specific law. You must now investigate whether you qualify under Spain's standard nationality rules which are generally much more restrictive and primarily cover children of Spanish citizens.

My grandfather was Portuguese. Is it easy for me to get citizenship?

It is possible but not guaranteed and it is not an easy process. As a grandchild you must apply for naturalisation which requires you to prove an 'effective connection' to Portugal. This includes demonstrating A2-level Portuguese language proficiency and may involve other evidence like regular travel to Portugal or cultural ties. The process is discretionary and more complex than the direct 'attribution' of citizenship available to children of Portuguese nationals.

What does 'effective connection' for Portuguese grandchildren actually mean?

The law does not provide a rigid definition leaving it open to interpretation by the authorities. However established practice shows that key elements include a certified A2 level of Portuguese language proficiency and a clean criminal record. Other factors that can strengthen a claim include owning property in Portugal regular visits to the country participation in local Portuguese community activities in your home country or having business interests in Portugal. You should check official guidelines for the most current criteria.

Can a DNA test prove my Spanish or Portuguese ancestry for my application?

No. While a DNA test can be a fascinating tool for personal genealogical research it holds no legal weight in a citizenship application. Spanish and Portuguese authorities require a verifiable paper trail of official government issued documents such as birth marriage and death certificates. These civil records are the only accepted form of proof to establish the legal family relationships required for citizenship by descent. A DNA result cannot substitute for this official documentation.

My ancestor changed their name after emigrating. Is this a problem?

It can be a significant problem if not handled correctly as it breaks the documentary chain linking you to your ancestor. You must provide official evidence of the name change. This could be a court order or other legal document explicitly stating the change from the old name to the new one. If no such document exists you may need to rely on affidavits and other secondary evidence but you must check with the consulate if this is acceptable.

Do I need to speak Spanish or Portuguese to apply for citizenship by descent?

For most standard descent routes for children of citizens in Spain and Portugal there is no language requirement. However for grandchildren of Portuguese citizens applying for naturalisation a certified A2 level of Portuguese language proficiency is a mandatory part of demonstrating an 'effective connection'. For all other cases while not required a basic knowledge of the language is always beneficial for navigating the process and engaging with consular staff.

How do I prove my ancestor did not naturalise in another country?

This is a critical piece of evidence often called a 'certificate of non-naturalisation'. You must request an official search from the immigration and naturalisation authorities of the country where your ancestor settled. For example in the United States this would be requested from U.S. Citizenship and Immigration Services (USCIS). This document certifies that a search of their records found no evidence of your ancestor becoming a citizen of that country.

If I get Spanish or Portuguese citizenship can my spouse and children get it too?

Your minor children can typically acquire citizenship through you once your own citizenship is confirmed but you must register their births properly. Your adult children would likely need to make their own separate applications based on their own lineage. Your spouse does not automatically become a citizen. They may be able to apply for citizenship through marriage but this is a separate process with its own requirements which often include residency and language tests.

Can I apply by travelling to Spain or Portugal instead of using a consulate?

In some specific cases it is possible to process an application in person in the country but this is complex. It usually requires you to establish legal residence in the country first which involves a separate visa process. For most people applying from their home country through the relevant consulate is the standard and recommended procedure. Applying in-country can introduce additional legal and logistical hurdles and is not a shortcut.

Can I keep my current citizenship if I get a Spanish or Portuguese passport?

Portugal fully permits dual citizenship so you would not be asked to renounce your existing nationality. Spain's policy is more complex. While it generally permits dual citizenship with most countries in practice and has specific treaties with Ibero-American countries the Philippines Andorra Portugal and Equatorial Guinea you should always check the laws of your original country. Some countries do not permit their citizens to voluntarily acquire another nationality.
