About the service
What is the Spanish Citizenship by Birth?
Spain, the country where you or your child took your first breath, offers a powerful gift: Spanish Citizenship by Birth. This right, known as ius soli (right of the soil), ensures that under specific circumstances, being born here automatically grants Spanish nationality.
This is not a universal rule for every child, but a crucial protection for many.
The most important and common scenario is nationality with “simple presumption”. This applies if you, the foreign parents, are from a country that does not automatically grant nationality to children born abroad.
Countries like Argentina, Brazil, Colombia, Costa Rica, Cuba, Peru, and Uruguay, among others, follow this principle. If their child is born in Spain, they are at risk of being stateless. Spain prevents this by granting them Spanish nationality from birth.
This makes the process a straightforward declaration, not a long application.
This path is fundamentally different from other types of nationality. It doesn’t require residency periods for the child or integration exams. It is a direct recognition based on the place of birth and the parents’ specific legal circumstances.
Another key scenario is for children born in Spain to stateless parents (apátridas) or whose parentage cannot be determined. Spain ensures these children have the full protection and rights of a citizen from the very beginning.
Our expertise is in navigating the nuances of Spanish and international nationality law. We analyze your specific case, gather the essential consular documents to prove your child’s eligibility, and manage the entire registration at the Spanish Civil Registry.
We turn a situation that can seem complex into a clear and efficient process, securing not only your child’s passport but also a pathway to your own residency in Spain through arraigo familiar.

Dario speaks excellent English, which made communication easy and comfortable, and he was always responsive, patient, and clear in explaining everything. He and his colleagues handled every detail with care, efficiency, and in a very timely manner, which gave me a lot of confidence and truly made my life so much easier throughout the entire process.

A friend recommended Illay Legal to help obtain my permanent residency in Spain. Exceptional service! Marc explained every part of the process clearly and precisely. Once I provided all the necessary details, the team did all the work: pre-completed the necessary paperwork, helped retrieve padron and digital tax certificate, secured appointments in my preferred neighbourhood and checked in with me before and after both appointments. I subsequently switched both my tax and business accountancy contracts to Marc's firm and have enjoyed the same very high level of service. Communication via email and WhatsApp, and extremely responsive to answering any small or large questions/concerns. A huge endorsement to the whole team - I would highly reccomend.
