Portugal Citizenship by Descent: A 2026 Eligibility Guide

You can apply for Portugal citizenship by descent if you have at least one parent or grandparent who holds Portuguese citizenship. But it’s a bit more complex than just tracing an ancestral lineage.

To avoid rejections or delays, it’s important to know how Portuguese citizenship by descent is attributed, which documents you need, and what you need to do before lodging an application.

In this article, we’ll explore eligibility, how to prove effective ties to Portugal, and the application process, so that you’ll have a better understanding of how it works.

Portugal Citizenship by Descent: Key Takeaways

You can apply for Portuguese citizenship by descent if you have at least one Portuguese parent or grandparent.

You must prove your ancestry through an authenticated birth certificate or a marriage certificate.

It allows you to apply for a Portuguese passport, giving you visa-free travel to 187 countries.

It costs €175, and you can apply at several places.

Citizenship by descent is when you become a Portuguese national because at least one of your parents or grandparents is or was a Portuguese citizen. Also known as citizenship by ancestry or origin, the process is not automatic. You must prove your parents’ or grandparents’ citizenship, and apply to have your own citizenship recognized.

It allows you to get Portuguese citizenship without having to live in Portugal, though you must provide extensive documentation and meet specific requirements for each generation. This includes birth and marriage certificates, as well as proof that your parent or grandparent did not lose their Portuguese citizenship.

If you can demonstrate a direct family connection to a Portuguese citizen, you may be eligible to claim citizenship through this avenue.

In addition to citizenship by descent, other ways you can also obtain Portuguese citizenship are by birth, naturalization, or marriage.

Visa-free travel within the EU: Portuguese citizenship gives you the right to live, work, and travel within the entire European Union.

Access to high-quality healthcare: You can access Portugal’s public healthcare system, along with healthcare coverage across the EU under certain conditions.

Educational opportunities: You can study at Portuguese universities and benefit from lower tuition fees available to EU citizens.

Interconnected legacy: Once granted, Portuguese citizenship can often be passed on to your children.

High quality of life: If you choose to relocate, Portugal offers a stable environment, strong infrastructure, and a relatively low cost of living compared to other Western European countries.

Portuguese law clearly outlines how to get citizenship through at least one of your Portuguese parents or grandparents:

Child of a Portuguese parent

• If you are born in Portugal to a Portuguese citizen, you automatically acquire Portuguese citizenship at birth.
• If you are born outside Portugal to a Portuguese citizen, you are eligible for citizenship by descent, but your birth must first be registered with the Portuguese civil registry.
• If the Portuguese parent was serving the Portuguese State abroad, for example, as a diplomat or military personnel, citizenship is automatic.

There is no requirement to prove Portuguese language skills or provide a criminal record certificate, and there is no age limit to formalize your citizenship later in life.

Grandchild of a Portuguese citizen

If you have at least one Portuguese grandparent, you can apply for citizenship by descent, provided the grandparent did not lose their nationality. To qualify, you must:

• Declare your intention to be Portuguese.
• Demonstrate an effective connection to Portugal.
• Register your birth in the Portuguese civil registry.

There is no age restriction for grandchildren applying. However, you can’t apply for citizenship by descent if you have been sentenced to three years or more in prison for a crime that is punishable in Portugal, or are involved in terrorist activities.

Great-grandchildren are generally not directly eligible unless their parent or grandparent first obtains Portuguese citizenship. Citizenship must be recognized generation by generation and cannot be skipped over.

The government has set out several ways to prove a genuine link to Portugal:

• Portuguese language proficiency: Showing the ability to speak and understand Portuguese at an A2-level.
• Cultural and community involvement: Participation in Portuguese cultural associations, frequent visits to Portugal, or engagement in Portuguese traditions.

While cultural involvement can support your application, language proficiency is the main legal requirement. You can prove your Portuguese language skills through one of the following:

• Certificate of proficiency obtained from a Portuguese private school or public school.
• Certificate of proficiency issued by the Portuguese Consulate during residency abroad, provided the Portuguese proficiency exam was taken through the Center of Evaluation of
• Portuguese Language (CIPLE) in Portugal or in other designated exam centers worldwide.
• Certification of proficiency in Standard European Portuguese as a second language from any authorized Portuguese Evaluation Centre.
• A diploma from a recognized Portuguese public or private educational institution.
• School diploma from an educational institution in a Portuguese-speaking country

Once you have all the necessary documentation and paid the fee, applications can be made in person at the Central Registry Office in Lisbon, at the Nationality Desk of the Central Archive of Porto, the various civil registry offices across the country, or a Portuguese Consulate in your country.

You can also mail your applications to the Institute of Registries and Notaries (IRN) or the Central Registry Office in Lisbon.

While there is the option to lodge an application online, this can only be done by your lawyer or solicitor.

After successfully obtaining Portuguese citizenship by descent, the next step is to apply for your Portuguese passport. This gives you the freedom to move within the European Union and visit 187 countries visa-free.

Here’s a step-by-step guide to help you through the process of obtaining a Portuguese passport:

• Eligibility: Ensure you have your Portuguese Citizenship Card as proof of your Portuguese citizenship.
• Schedule appointment: Book an appointment at the nearest Portuguese consulate, a Portuguese civil registry office, or a citizen’s shop (Loja do Cidadão).
• Prepare documents: Gather all the necessary documents, including your Portuguese Citizen Card, proof of payment for passport fees, and a completed passport application form.
• Attend appointment: Attend the appointment in person, as you may also need to have biometric data taken.
• Pay fees: Pay the required passport application fee.
• Collection or delivery: After your application is processed and approved, you’ll receive your Portuguese passport.

The Portuguese passport needs to be renewed every 10 years for adults and every two years for children under the age of five. Always check the expiry date and start the renewal process well in advance of any planned travel.

Processing Portuguese citizenship applications can take up to a few months for the children of Portuguese parents and a couple of years in other circumstances. This duration is due to the multiple checks and processes required to verify and confirm all the information provided.

The fee for Portuguese citizenship applications is €175, though it may vary slightly depending on the legal route. In most cases, or if you are mailing in your application, you can make an online payment.

There are several organizations and entities that are involved in the process or can be utilized to find the documentation required to prove your ties to Portugal and obtain Portuguese citizenship:

• Conservatória dos Registos Centrais: The Portuguese central registry office where applications for Portuguese citizenship are processed.

• Portuguese Embassy and Consulates: These are International offices where application documents are acquired and submitted outside Portugal. If you need to make an appointment, check with your local consulate.

• Instituto dos Registos e do Notariado (IRN): Portuguese government agency responsible for registering and notarizing civil, property, commercial, and vehicle records, ensuring legal documentation and public trust.

• Portuguese Civil Registry Offices: District offices where births, deaths, and marriages are officially documented and registered. This is where you’ll find documentation for family ties to Portugal.
