Lawyers Specializing in Spanish Nationality in Barcelona – Citizenship and Legal Procedures

Obtaining Spanish citizenship is a crucial step for anyone who wants to live, work, and enjoy all their rights in Spain and the European Union. At Martínez Caballero Abogados, we guide you through the entire legal process—from assessing your situation to submitting your application and handling appeals in the event of any issues.

What is Spanish citizenship?

Spanish citizenship is a legal bond that grants individuals the status of citizen of Spain, with all the associated rights and obligations. It allows for free movement, work, and residence throughout Spain and the European Union, as well as the right to vote and access to public services.

In Spain, there are several ways to obtain it—not only through long-term residence, but also through marriage, naturalization, descent, or a letter of naturalization.

What are the ways to obtain Spanish citizenship?

Citizenship by Marriage

We help you obtain or renew your residence permit for work, study, exceptional circumstances, or family reunification. We handle the entire process and the necessary documentation to avoid mistakes and expedite your application.

Nationality by Choice

It applies to certain individuals who are eligible to obtain it because they have a legal relationship with Spanish citizens (for example, children of Spanish citizens or individuals taken in by Spanish citizens).

Citizenship by naturalization

It is a discretionary measure available to the Spanish government for exceptional cases, granted by Royal Decree.

Citizenship by Residence

The most common way to obtain Spanish citizenship is through legal and continuous residence in Spain. Generally, applicants must have lived legally in Spain for:

  • 10 years of continuous legal residence.

  • 5 years for refugees.

  • 2 years for nationals of Ibero-American countries, Equatorial Guinea, Portugal, the Philippines, or those of Sephardic origin.

  • 1 year in special cases (those born in Spain, children of Spanish nationals, widowers of Spanish nationals, etc.).

Our attorneys review your situation to determine the fastest and most appropriate course of action for your case.

Common Requirements for Citizenship

General requirements include:

  • Continuous legal residence for the period required based on your situation.

  • Good civic conduct, with no criminal record in Spain or in your country of origin.

  • Integration into Spanish society, as assessed by mandatory exams (CCSE and, where applicable, DELE).

  • Complete documentation and affidavit.

Our team helps you gather and verify all the necessary documents before submitting your application to minimize errors and delays.

How We Help You Through the Process

Documentation Assistance and Preliminary Preparation

We review your situation and let you know exactly which documents you need to provide, from proof of residence and employment to criminal background checks and proof of registration with the municipal registry. This ensures that your application is complete before you submit it.

Preparation for the CCSE and DELE Exams

We provide guidance on the mandatory exams required to demonstrate constitutional literacy and language proficiency. We help you understand the format, requirements, and resources to help you prepare more effectively.

Online registration and official tracking

We handle the submission of your application on your behalf and provide ongoing follow-up until a decision is reached, keeping you informed of the status of your application.

Remedies Against Denials

If your application is denied, we will advise you and prepare administrative or judicial appeals to defend your rights and maximize your chances of obtaining citizenship.

Tuve una excelente experiencia con la abogada Diana y su equipo. Desde el inicio nos orientó con muchísima claridad y paciencia en todo el proceso, siempre pendiente de cada detalle y dispuesta a ayudarnos incluso sin compromiso, aún haciéndonos un plan de pagos para ayudarnos cuando tuvimos un percance económico que nos dificultó la situación. Gracias a su guía, todas nuestras citas y trámites salieron bien y sin ningún inconveniente. Es una persona muy profesional, con gran calidad humana, y realmente se nota que le importa ayudar a sus clientes más allá del trabajo. La recomiendo completamente.
