The request for Portuguese citizenship is very often the most important and final step of the immigration process.
The procedure for obtaining Portuguese nationality, through residency, Portuguese ancestry, marriage, or birth rights, involves legal analysis, document preparation and compliance with Portuguese nationality law. You can get help from an experienced Portugal citizenship lawyer to prepare your application correctly and submit it according to the current legal requirements.
The legal team at Portugal Residency Advisors® assists international clients in their Portuguese citizenship and nationality applications, from the initial eligibility assessment to the final submission and follow-up with the Portuguese authorities.
Why to hire a Portugal Citizenship Lawyer?
Portuguese nationality law is very technical, particularly with the recent changes made in 2026.
There are many applicants that underestimate how detailed the citizenship applications can be. Especially when it comes to foreign documents, civil registry records, translations, apostilles, residency calculations and proof of connection with Portugal.
A qualified lawyer with experience in citizenship in Portugal can help you navigate the process and avoid mistakes that may delay or jeopardize an application.
Citizenship Law Is Never Static
In recent years, Portugal’s nationality framework has gone through several reforms.
Amendments were made to the Portuguese Nationality Law in 2026, substantially modifying the regulations concerning residency periods, the calculation methods and the implementation.
For more detail on these legal changes and how they could impact future applicants, see our guide to Portugal Nationality and Citizenship Changes 2026.
Civil registry and Documents issues
Often, citizenship applications include documents from multiple countries.
Birth certificates, marriage certificates, criminal records, translations, apostilles and historical family documents must all comply with Portuguese legal standards. Even small differences in names, dates or family records can hold things up.
A Portugal citizenship lawyer will review and prepare all necessary documentation prior to submission to minimize the potential for any administrative issues later in the process.
Communication With Portuguese Authorities
Nationality applications are generally processed through the IRN (Instituto dos Registos e do Notariado), Portugal’s civil registry authority.
Your lawyer monitors the application, follows up with the authorities when necessary, and responds to any additional document requests during the process.
Portuguese Citizenship Services We Provide
Our citizenship legal team assists clients across several Portuguese nationality pathways.
1. Residency Based Citizenship
Many foreigners can apply for Portuguese citizenship after the required period of legal residence in Portugal.
This is a very popular route for D7 Visa holders, Digital Nomad Visa holders and Golden Visa investors.
In our guide “Portugal Citizenship: The Ultimate Guide for 2026” we explain the whole naturalization process in detail.
2. Citizenship by Descent
Portuguese nationality may also be available to:
- children of Portuguese citizens,
- grandchildren of Portuguese citizens,
- and certain descendants of Sephardic Jews.
These applications often involve genealogical records and older civil documentation from Portugal and abroad.
3. Citizenship by Marriage or De Facto Relationship
Foreign spouses and long-term partners of Portuguese citizens may be entitled to Portuguese nationality after the legally required period of relationship.
Sometimes this process requires you to prove effective connections to the Portuguese community (depending on the circumstances).
4. Portuguese Citizenship: Children Born in Portugal
In some legal situations children born in Portugal to foreign parents may acquire Portuguese nationality.
The Portuguese Citizenship by Birth guide covers the rules for nationality for children born in Portugal or abroad.
5. Litigation over delays in citizenship applications
In Portugal, for example, the processing of nationality applications can sometimes take a long time.
Sometimes it is possible to take legal steps to challenge undue delays or administrative inertia.
Our article Why Is My Portuguese Citizenship Application Taking So Long explores this issue further.
