Portuguese Citizen Card
After nationality registration, eligible citizens can proceed with the Portuguese citizen-identification documentation.
No hidden fees. No surprises. Every package includes your NIF and bank account setup, with a 50% discount for the second person and a 70% discount for dependants.
Portuguese nationality law provides routes for people with a Portuguese parent and, under specific conditions, grandchildren of Portuguese nationals. The correct route depends on your generation, the Portuguese ancestor's status and the documents available to prove the family line.

Portuguese citizenship by descent is a nationality route based on a qualifying Portuguese family connection. Instead of first obtaining residence in Portugal and later applying for naturalisation, eligible applicants can seek nationality based on their Portuguese parent or qualifying Portuguese grandparent.
If you were born outside Portugal and your mother or father is Portuguese, Portuguese Justice guidance provides a nationality route for children of Portuguese nationals. The applicable declaration or registration must be completed and the Portuguese parentage must be established.
You do not need both parents to be Portuguese. The official Justice guidance refers to a person born abroad who has a Portuguese mother or father.
Being born outside Portugal does not by itself prevent the child of a Portuguese citizen from obtaining Portuguese nationality through the applicable route.
The Portuguese parent's nationality status and the way the parent-child relationship is recorded can affect the documentation required.
The Portuguese birth and nationality records need to correctly reflect the family relationship and the applicable nationality declaration.
Yes, Portuguese nationality law provides a route for a person who has a Portuguese grandmother or grandfather who was Portuguese by origin and has not lost Portuguese nationality, subject to the statutory requirements.
This is an area where older online information can be misleading. The current 2026 nationality law does not create a normal direct citizenship-by-descent route for every great-grandchild.
The case is built around documentary evidence establishing the Portuguese ancestor and the uninterrupted chain connecting that ancestor to the applicant.
The strongest citizenship-by-descent files clearly connect each generation through official civil records.
Confirm whether the relevant ancestor is your parent or grandparent and establish their Portuguese nationality status.
Obtain the birth and, where relevant, marriage records connecting the Portuguese ancestor to their child.
Document every generation until the family relationship reaches the person applying for Portuguese nationality.
Differences in names, dates, places of birth and marital records should be identified before submission.
A surname change does not necessarily break the family line, but the documentary evidence connecting the records must be established.
The discrepancy should be assessed and corrected or explained where necessary before the nationality application.
Additional civil-registry or archival research may be needed before determining whether the lineage can be documented.
That is common in international families. Each foreign document should be checked for the appropriate certification, legalisation and translation requirements.
Foreign civil-status documents may need to be legalised or apostilled and translated according to the applicable Portuguese procedure and the country where the document was issued.
One dedicated team stays with you through the preparation and nationality application process.
For the direct child-of-Portuguese route, Portuguese Justice guidance does not impose a prior Portuguese-residence requirement. This is fundamentally different from naturalisation based on residence.
If you were born abroad and have a Portuguese mother or father, the nationality route is based on your parentage rather than first establishing residence in Portugal.
Grandchild applications have additional statutory requirements, including the required connection to the Portuguese community. They should therefore not simply be treated as identical to child-of-Portuguese applications.
The two routes are fundamentally different. Choosing the correct legal basis before preparing documents can save significant time.
A missing generation document can make the family chain difficult to establish.
Spelling differences between records should be identified and assessed before filing.
Marriage records can sometimes be important for connecting or explaining different surnames between generations.
Documents issued abroad may require apostille, legalisation or another recognised form of authentication.
Foreign-language documents may require an accepted Portuguese translation.
A parent, grandparent and more distant ancestor can trigger different legal routes. The family generation should be confirmed before applying.
Portugal changed its Nationality Law in May 2026. The new rules entered into force on 19 May 2026 and changed several nationality routes and requirements.
