Article 1-D: Original Nationality by Origin (Atribuição)
Under Article 1, paragraph 1, item (d) of Portuguese Nationality Law, individuals with at least one grandparent of original Portuguese nationality can claim direct Portuguese citizenship without moving to Portugal or maintaining previous residence permits.
- Original vs Acquired: Unlike marriage or 5-year naturalization, this is an atribuição (original nationality). You are recognized as Portuguese from birth, enabling you to transmit original Portuguese citizenship to your minor or adult children.
- Skipping the Intermediary Generation: Even if your parent (the child of the Portuguese grandparent) never claimed Portuguese nationality or is deceased, grandchildren apply directly.
The Mandatory Document & Genealogy Chain
Constructing an unbreakable evidentiary trail is crucial for approval at the *Conservatória dos Registos Centrais* in Lisbon:
- Grandparent Birth Record (Assento de Nascimento / Batismo): Original certified copy from the Portuguese civil registry or parish church archive (if born prior to 1911).
- Full-Line Birth Certificates (Inteiro Teor / Reprográfica): For both the intermediary parent and the applicant, legalized with the Hague Apostille and translated into Portuguese by a certified translator.
- Criminal Records: Certified background checks from all countries of citizenship and residence after age 16.
- Language Proof: Official CIPLE A2 certificate or proof of schooling in a Portuguese-speaking nation.
