This gives you access to great healthcare, education, and a high standard of living.

What is Spanish Citizenship by Descent?

Spanish citizenship by descent, or “jus sanguinis,” allows individuals to apply for citizenship through a direct line of Spanish ancestry, providing a way for descendants of Spanish citizens to reclaim their heritage. Under Spanish immigration law, this applies to those with a Spanish parent or grandparent and requires proving family ties through official documents like birth and marriage certificates. Applicants must submit their case to the Spanish authorities, who verify the documentation and eligibility.

What is the Spain Citizenship by Democratic Law?

The Spain Citizenship by Democratic Memory Law, also known as the “Grandchildren Law,” was introduced in 2022 to allow children and grandchildren of Spaniards who left the country during the Civil War to apply for Spanish citizenship. It was created to recognize and repair the impact of political exile. This law offers a path to citizenship for people of Spanish descent, even if they were born abroad. Applicants do not need to live in Spain or give up their current citizenship. The law is open for a limited time, with applications accepted until October 2025.

Benefits of Spanish Citizenship by Descent

• Consular benefits: Spanish citizens can seek help from Spanish embassies and consulates worldwide, a service non-citizens don’t have.

• Run a business across the EU: Start and operate businesses in other EU countries without extra taxes or trade barriers.
• Family benefits: It’s easier for family members to join you, and non-EU family members may qualify for simplified residence permits.
• Strong passport: A strong benefit of obtaining a Spanish passport is the high level of global mobility it offers.

Who can apply for Spanish Citizenship by Descent?

There are several eligibility criteria and steps that determine who can apply for Spanish citizenship by descent. First and foremost, you must validate your claim to Spanish heritage, which can be either through your parents or grandparents.

You can obtain for Spanish citizenship by descent if:

• Born to a Spanish father or mother – The child automatically acquires Spanish nationality regardless of the year.
• Born in Spain to foreign parents, with at least one parent born in Spain—Under the 1978 Constitution, the child acquires Spanish nationality by birth if one parent was born in Spain (except children of diplomats).
• Born in Spain to stateless foreign parents or those whose nationality laws don’t grant nationality – The child can be declared Spanish at the Civil Registry under the presumption of Spanish nationality, in effect since 1982.
• Children born in Spain whose parents’ identities are unknown—Under the 1982 Nationality Law, a child is presumed to be Spanish by birth if their first known residence is Spanish territory.
• Children under 18 adopted by a Spanish national are considered Spanish by origin; if over 18, they may opt for nationality within two years of adoption under the 2007 reform of the Nationality Law.

Requirements for the Spanish Citizenship through the Grandchildren Law

Spain’s Citizenship by Democratic Memory Law, also called the “Grandchildren’s Law,” is divided into different cases to reflect the various reasons why families lost or couldn’t pass down Spanish citizenship. These cases help recognize different historical situations, such as exile, marriage laws, or past discrimination that affected people in different ways.

Because each case is based on a specific family situation or legal reason, the requirements and documents you need will depend on which case you qualify for.

Independent of the reason to apply for citizenship, the applicant needs to comply with the following requirements:

• Oath or promise of fidelity to the King and obedience to the Constitution and the Spanish laws.
• Registration of the acquisition of nationality in the Spanish Civil Registry.

Applications must be submitted in person at your local Spanish consulate, and the deadline for submission is 21 October 2025. Depending on the applicant’s case, the application process through the Grandchildren’s Law can take one to two years.

How to Apply for Spanish Citizenship by Descent

You can submit applications for Spanish citizenship by descent in person to the Civil Registry, Consulate, or Embassy. Here is the general application process for how to get Spanish citizenship by descent:

Step 1: Determine eligibility

Through Parents: You qualify if one or both of your parents were Spanish citizens at the time of your birth.

Through Grandparents: You may apply if a grandparent was born in Spain or held Spanish citizenship. This includes cases where Spanish women lost their nationality by marrying non-Spanish citizens before 1978.

Step 2: Book an appointment

Schedule an appointment with your local Spanish Embassy, Consulate, or Civil Registry Office. Provide your name, phone number, and the reason for your visit (citizenship by descent application).

Step 3: Prepare your documents

Gather documents proving your relationship to your Spanish ancestor, including birth, marriage, death certificates, proof of identity, and proof of your ancestor’s Spanish nationality. Ensure all foreign documents are apostilled and translated into Spanish by an official translator. If applying under Spain’s Democratic Memory Law, you may need documents proving your ancestor’s exile or political persecution.

Step 4: Submit your application

Attend your scheduled appointment and submit your completed application form along with the required documents. If you’re a minor, your parents must apply on your behalf. In cases of divorced or separated parents, written consent from the non-applying parent may be necessary. The authorities may ask for further documentation or clarification, so keep extra copies and backups of all your papers.

Step 5: Await a decision

The processing time varies depending on the consulate or registry office. If your application is successful, you’ll be registered as a Spanish citizen.

Final Step: Obtain your Spanish citizenship and passport

Once your citizenship is officially granted, you can apply for a Spanish passport and national ID card (DNI). This marks the completion of your journey to becoming a recognized Spanish citizen.

If your parents’ marriage or divorce occurred outside Spain, ensure it is registered with the Spanish Civil Registry. This keeps your citizenship status clear and undisputed for future generations.
