About the service
What is the Spanish Citizenship by Origin?
Being a Spanish citizen by origin means you are considered Spanish from the moment of your birth. This is the strongest and most fundamental link to Spanish nationality, a right that cannot be taken away and that sets you apart from all other forms of acquisition.
It’s not a status you apply for, but a reality you formalize. This blood right or ius sanguinis is your birthright.
This right belongs to you automatically if you fall into one of these core groups. Primarily, if you were born to a Spanish father or mother, regardless of where in the world you were born. Your connection is direct and absolute, making you eligible for Spanish nationality as the child of a Spaniard.
Additionally, if you were born in Spain to foreign parents, but at least one of them was also born in Spain, you are also a citizen by origin. This protects families with deep, multi-generational roots in the country.
The law also protects the most vulnerable, granting Spanish Citizenship by Origin to children born in Spain to stateless parents or those whose parents’ nationality is not passed on, preventing anyone from being stateless.
Understanding this process is about shifting your mindset from “applying” to “declaring.” You are simply requesting the official recognition of your Spanish nationality.
This is a crucial distinction, as it doesn’t require subjective integration tests or long residency periods. The entire process hinges on providing unquestionable proof of your lineage or circumstances through precise documentation.
For the many children of Spanish citizens born abroad, the process typically involves a consular birth registration. This means presenting your case at the Spanish Consulate in your country of residence.
Navigating the specific requirements of each consulate, from legalizing foreign documents with the Hague Apostille to official translations, is a critical step where professional guidance prevents years of delays and frustration.
Our expertise is in building an irrefutable case for your recognition as a Spaniard. We navigate the complexities of both the Spanish Civil Registry and various consulates worldwide.
We handle the intricate task of gathering historical birth certificates, legalizing documents across borders, and presenting your file so that your rightful citizenship is officially inscribed and recognized without setbacks.

I had an amazing experience working with Dario and his team throughout my visa process. They made everything completely stress-free and were incredibly helpful every step of the way. 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. By far the best lawyer I’ve worked with in Barcelona. I couldn’t have asked for a better experience and would highly recommend Dario and his team to anyone needing help with visas or immigration.Posted on Google Marc Ovalle22/03/2026Trustindex verifies that the original source of the review is Google.

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.
