    What Is Spanish Citizenship by Birth?

    Spanish citizenship by birth is a right that automatically confers Spanish nationality on an individual if they were born in Spain and one of their parents is a Spanish citizen. It is also referred to as jus sanguinis (right of blood) or nationality by origin.

    If you were born outside Spanish territory and neither of your parents is Spanish, you can naturalise. Unlike Spanish citizenship by birth, which can be inherent, foreigners can acquire Spanish citizenship through naturalisation by applying after meeting the eligibility requirements. One of the requirements is that you will swear an oath of allegiance.

    Who Qualifies as a Spanish Citizen by Birth?

    An individual can be granted Spanish citizenship by birth according to the Spanish civil code if they meet the following eligibility requirements:

    • A child whose father and mother are Spanish citizens, regardless of their birthplace
    • A child born in Spain to foreign parents is eligible for citizenship if at least one parent was born in Spain, excluding children of diplomats.
    • A child born to foreign parents who are considered stateless, and if the minor cannot be granted a nationality by the parents’ country of origin
    • A child born in Spain, but does not know his parents, whose first known place of residence is Spain
    • An adult (over 18 years old) who meets the above qualifying conditions can opt for it within two years of becoming eligible
    • A foreign child or adult adopted by a Spanish citizen. An adopted adult aged 18 or older can opt for it within two years of the adoption.

     

    Nationality by Option – For Children of Spanish Citizens

    You can become a Spanish citizen by using the ‘option’ route. It is a fast-track route for those with close family ties in Spain. Below is a list of those who can claim nationality by option:

    • Individuals whose parents are Spanish citizens, who were either born in Spain or adopted, and who are over 18 years old.
    • Individuals whose parents are citizens, born in Spain but were exiled during the Spanish Civil War and dictatorship.
    • An adult whose parent obtained Spanish citizenship by option.

    To apply, you must provide evidence that you are related to a Spaniard, such as your birth certificate and your parents’ passports. You will be required to swear an oath to obey Spanish laws. Spain typically allows dual nationality, however, you must renounce any previous nationality if you are not permitted for Spanish dual nationality.

    Your details will also be recorded in the Spanish civil register. Minors must apply with the help of a legal representative. To apply independently, you must be emancipated and at least 18 years old.

    To avoid common mistakes, such as missed deadlines, it is advisable to use a legal representative. Our immigration lawyers at Total Law can provide you with guidance on the requirements and assist you throughout the application process. We can also assist you in obtaining a Spanish identity card and passport.

    The Spanish Democratic Memory Law (20/2022) includes specific categories of people who are eligible for Spanish nationality by option. According to the law, individuals born outside Spain to a Spanish parent or grandparent who was exiled, lost their citizenship, or renounced it are eligible to apply. This law makes it easy for grandchildren of Spanish citizens, whether born abroad or in Spain, to claim nationality.

    However, new applications under the Democratic Memory Law closed on October 22nd, 2025, and there is no current deadline extension. This should not discourage you from applying for citizenship in alternative ways. For instance, you could get citizenship through residency.

    Immigration laws undergo frequent changes. Our immigration solicitors are up to date with the latest changes (including consular requirements) and can advise you on the best possible path.

    How to Apply for Spanish Citizenship by Birth (Step-By-Step)

    For a Newborn

    If you have a newborn who meets the eligibility requirements for citizenship by birth, the child can automatically acquire Spanish nationality after birth by following the steps outlined below:

    Step 1: Register the Birth

    If you have a child born in Spain, you should register their birth at the municipal civil registry in the region where the parent is resident, with the supporting documents, such as the parent’s passport. Ensure that your documents are complete and accurate. The healthcare provider, hospital, or adult present at the child’s birth can initiate the registration. The hospital is expected to do it within 72 hours after birth.

    As a parent, you can begin registration within 10 days of the baby’s birth, which can be extended for another 30 days.  For children born abroad, the birth can be registered at the Spanish consulate in the child’s country of residence. For instance, if the child was born in the UK, you can register the birth at the Spanish consulate in London. A delay in registration can prevent the baby from exercising the right and benefit of being a Spanish citizen.

    This registration establishes an official record of the baby’s birth. It also confirms their ‘right of blood’ if they are eligible. The date and method of acquiring citizenship are recorded in the civil register.

    Step 2: Obtain the Birth Certificate

    Once you have registered the birth, you should wait for the birth certificate to be ready. The processing time may vary from a few days to several weeks, depending on the location of your application and the volume of submitted applications. Once the child’s birth certificate is ready, you can choose to receive it in person or by mail.

    Step 3: Obtain the DNI and Passport

    Once you have obtained the birth certificate, you can then apply for a Spanish DNI (National Identity Document) and passport.

    For an Adult

    Step 1: Register at the Civil Registry

    You must prove that at least one parent is Spanish, born in Spain to ‘stateless parents’, or that you meet other requirements. Visit the civil registry for registration. Once determined, an official record of your details will be registered in the civil registry.

    Step 2: Obtain the Birth Certificate, Passport, and DNI

    You can obtain your birth certificate after the registration at the civil registry.  To register, you must submit your supporting documents to prove your eligibility. For instance, you may need to submit an adoption document if you were adopted by a Spanish citizen or the passport of your Spanish parents. The processing time may take days or weeks. You will be contacted once it’s ready.  After you have obtained the certificate, you can then apply for a Spanish passport and DNI.

      Special Cases and Exceptions

      Citizenship by origin is possible in exceptional cases. According to Article 17 of the civic code, a child who is deemed stateless may be eligible for citizenship. In this case, the foreign parent and child are not recognised as citizens in any state. This is done to prevent the child from becoming stateless. Additionally, a child born in Spain whose parents are unknown is granted citizenship. This also means gaining Spanish nationality by presumption.

      Documents and Evidence Required

      The documents needed for Spanish citizenship by birth include:

      • An application form accurately filled and completed, showing your name (name of the child if registering a newborn)  and relevant details
      • A document proving the identity and nationality of the parent, such as a passport or birth certificate
      • The certificate that was issued by the medical practitioner at the hospital of birth
      • If the parent has adopted a child, they must also provide adoption papers.

      If a child doesn’t qualify for nationality by birth, foreign parents can wait a year in Spain to get nationality by residence. This means the baby will need to have lived in Spain for 1 year, legally and continuously, after birth to be eligible. The application can be submitted at the local civil registry where you reside.

      Common Problems and How to Avoid Rejections

      Some of the common problems encountered by applicants are:

      Lost Spanish Records and Missing Documents

      Applicants often encounter issues such as proving that their parents are Spanish. This can occur if the parents’ records are missing from the civil register due to incorrect details and documents provided by the applicant. This means that their birth cannot be verified. To process your application, you can get a literal birth certificate from the civil registry. To avoid a rejection of your application, you should provide all relevant documents, such as the passport of your parent and their birth certificate or baptismal certificate, to prove their nationality.

      Inconsistent Names Across Certificates

      Discrepancies in the provided names can result in rejection. For instance, the name on the parents’ birth certificate or any other document provided should match the record in the civil register. If a name has changed, a document must prove that the person is the same. A change of name, for example, requires a court order.

      Missed Declaration Deadlines

      Once it’s clear that you are eligible for Spanish citizenship by origin as an adult (over 18), you have 2 years to apply. If you can’t apply within the stipulated time, you can choose other options. For example, if you’re married to a Spanish citizen, you can apply for nationality by residency after one year of living together and obtaining your temporary residence permit. Your marriage certificate must be submitted to prove you are married.

      Appeal Process Overview.

      If you receive a denial of your application to claim nationality by origin, the reason will be stated. You can either reapply with the right documents or appeal the case if necessary.  Our experienced solicitors at Total Law can file an appeal on your behalf or reapply, depending on your situation.

      Dual Nationality and Retention Rules

      If you are applying for Spain citizenship, you must give up any previous nationalities that you have acquired because Spain only recognises dual citizenship through bilateral agreements with some countries. Foreign nationals not exempt will not be recognised in Spain with their nationality of origin once they acquire Spanish citizenship.  Citizens from Equatorial Guinea, Andorra, the Philippines, Sephardic Jews of Spanish origin, Portugal, and Latin American countries are exempt from this requirement. Some situations can cause the relinquishment of Spanish nationality. These situations are discussed in the next heading.

      Relinquishing Spanish Nationality

      If you are not exempt, acquiring a foreign nationality means relinquishing Spanish citizenship and its associated benefits. According to Article 24 of the Spanish Civil Code, emancipated minors who reside outside Spain and are citizens of another country will lose their Spanish nationality after three years of frequently using the foreign one. This also applies if the minor is not emancipated and becomes an adult (18 years old). This can be avoided if you choose to retain your Spanish citizenship.

      Retaining Your Spanish Nationality

      Foreigners who are not exempt can avoid losing their Spanish nationality if, within three years, they declare at the civil registry that they wish to retain their citizenship. If you are already 18 years old, you have until the age of 21 to declare your intention to maintain your Spanish nationality. If you are over 21 and didn’t meet the stipulated deadline under Article 22, you can apply for citizenship once you obtain legal residence in Spain.

                FAQ – Quick Answers to Common Situations

                Having a baby in Spain offers several benefits, such as:

                • Access to several options for obtaining Spanish citizenship. For instance, the baby could obtain, by simple presumption, or after one year of legal residence
                • Access to a Spanish medical expert
                • Access to low-cost public healthcare through the Spanish National Healthcare System (SNS) for legal residents and citizens

                • The Spanish passport allows visa-free access to the Schengen Area, including Switzerland and countries in the European Union and EEA, for 90 days.
                • Being a citizen gives you the legal right to live and work in Spain and other EU countries. This automatically means that you have obtained European citizenship.
                • You automatically have the right to vote.
                • If you reside outside Spain, you can have access to the protection and benefits from the Spanish embassy or consular office in your country of residence.
                • Minors granted Spanish nationality can have access to free and high-quality education in public schools.
                • You can obtain a dual nationality as long as you declare your intention to retain Spanish citizenship within three years of acquiring a new one.

                You can apply for Spanish nationality using the following routes:

                • Option
                • Discretionary conferral
                • Residency
                • Possession of status.

                You must meet the following requirements:

                • If applying through residency, you must have lived in Spain for the required number of years.
                • You must swear an oath to obey Spanish laws
                • You must renounce your other nationality unless your country is exempt
                • You must present your language test results as proof of your fluency in the Spanish language and your understanding of its society, unless you are from a Latin American country.

                ‘Jus soli’ means ‘right of soil’. This means granting nationality based on an individual’s place of birth. The Spanish government does not automatically grant nationality to individuals born in its territory unless they meet certain conditions. ‘Jus sanguinis’ refers to the right of blood. This means granting citizenship based on the origin of the parents. Spain automatically grants citizenship to children whose parents or one of the parents is originally a Spanish citizen.

                Yes. But it is not automatic. You must meet certain criteria. For instance, if you are aged or sick and under the legal custody of your Spanish child for two years, you can apply for nationality by residency. You can also obtain citizenship if you are older than 65 through the family reunification pathway.
