How it works

How citizenship through grandparents works

Understanding the two-generation connection.

i

Your grandparent — Portuguese

Portuguese citizen (by birth or naturalization).

ii

Your parent — potential route

May have a route to citizenship through their parent.

iii

You — potential applicant

May apply for Portuguese nationality if the statutory requirements are met.

Where both a parent and a grandchild have potential routes, the appropriate sequence depends on the family records, the parent's current status and the applicable legal requirements.

Documents

Documents you'll need

We guide you through every document — many we can obtain for you.

i

Your documents

Birth certificate, duly authenticated. Passport or identity document. Criminal record certificates must be issued by the competent services of the country of birth, the country of nationality and any country where the applicant has resided after reaching the age of criminal responsibility, in accordance with article 6(11) of the Nationality Law. The form, translation and authentication required depend on the issuing country.

ii

Parent's documents

Birth certificate (apostilled). Marriage certificate (if applicable). Passport/ID (if available).

iii

Grandparent's documents

Portuguese birth certificate*. Marriage certificate*. Death certificate* (if applicable).
* We obtain these from Portuguese archives.

We find Portuguese records

Most clients don't have their grandparents' Portuguese documents. That's okay — we work with Portuguese civil registries, parish records, and historical archives, and regularly locate records for grandparents who emigrated many decades ago.

How we work

Our step-by-step process

  1. Initial assessment. You tell us what you know about your Portuguese grandparent. We review the family records and the legal requirements and give you a written assessment of the route, the documents needed and any material risks.
  2. Genealogical research. We locate and obtain your grandparent's Portuguese records from civil registries, parish archives, and emigration databases.
  3. Document collection. We create your complete checklist and guide you through obtaining and apostilling your documents.
  4. Legal strategy. We advise on the appropriate sequence for the family's applications, based on the records and the applicable legal requirements.
  5. Application submission. We prepare and submit your complete dossier to Portuguese authorities and handle all follow-up.
  6. Decision and registration. If the application is approved, we obtain your Portuguese birth record, then guide you through the passport application.

FAQ

Common questions about citizenship through grandparents

Yes. If your grandmother or grandfather was Portuguese (born in Portugal or held Portuguese citizenship), you may be able to apply for Portuguese nationality by descent, provided the statutory requirements are met.
You will need: your grandparent's Portuguese birth certificate, your parent's birth certificate (showing the Portuguese grandparent), your own birth certificate, marriage certificates if names changed, your passport, and criminal background check. We can search Portuguese archives for missing documents.
Yes. The Azores are part of Portugal. If your grandparents emigrated from the Azores (São Miguel, Terceira, Faial, Pico, etc.), they were Portuguese citizens and you may claim citizenship through them.
Yes. You must demonstrate an unbroken chain from your grandparent to yourself. This means showing your grandparent's Portuguese citizenship, your parent's birth, and your own birth. We help compile this documentation.
Yes. Under the 2026 law, grandparent applicants must satisfy the applicable language, culture, history, national-symbols and civic-knowledge requirements, in addition to the remaining statutory conditions.
Residence in Portugal is not generally required for this route. Much of the preparation may be handled remotely, but any personal appearance or declaration required by the applicable procedure must be confirmed.
Processing times vary with the completeness of the records and the workload of the authorities. Cases with readily available documents tend to move more quickly; cases requiring extensive archive searches may take longer.
Our team can search Portuguese civil registries, parish records, and national archives to locate birth certificates, baptismal records, and other documents. Many families are surprised by what we can find.
Yes. You only need one grandparent to have been Portuguese. It can be your mother's side or father's side — grandmother or grandfather.
Children may have a separate nationality route depending on when they were born and the parent's status. Nationality does not automatically pass to all future generations after the applicant's naturalisation.
