Portugal Citizenship by Descent and the Sephardic Route: What Still Applies in 2026

Two distinct citizenship pathways exist for people who have never lived in Portugal at all: ancestry (descent from a Portuguese national) and the Sephardic Jewish community route (descent from Jews expelled from the Iberian Peninsula in 1496). Both have been significantly tightened in recent years. Both still exist. The rules for each are specific enough that generic summaries online frequently get details wrong — including whether each route is still open at all.

Here is the current picture for both.

Citizenship by Descent: The Jus Sanguinis Rules

Portuguese nationality can be transmitted through bloodlines under the jus sanguinis principle established in Law 37/81. The rules for transmission have evolved through amendments in 2006, 2018, 2020, and 2026.

First Generation (Child of a Portuguese Citizen)

A person born to at least one Portuguese parent is generally attributed Portuguese citizenship at birth, regardless of where they were born. This applies whether the Portuguese parent acquired citizenship by birth, descent, or naturalization.

The practical requirement: your birth must be registered in the Portuguese civil registry. If your Portuguese parent is a citizen but your birth has never been registered in Portugal, you are not recognized as Portuguese in the system. Registration can be done retroactively, even for adults, through the Portuguese consulate in your country of residence.

Second Generation (Grandchild of a Portuguese Citizen)

This is where most ancestry-based applicants fall. Grandchildren of Portuguese citizens can claim citizenship if:

• One grandparent is Portuguese
• The parent through whom the claim passes was NOT Portuguese (this matters — if the intermediate generation is already Portuguese, the claim comes through a different path)
• The applicant can demonstrate an "effective connection to the Portuguese community"

The 2020 amendment simplified and expanded the grandchildren route. The 2026 amendments did not substantially change it, though implementation is stricter. The "effective connection" requirement for grandchildren is assessed differently than for naturalization applicants — demonstrating some knowledge of Portuguese language and some connection to Portuguese culture or community is generally sufficient.

The registration process for grandchildren involves submitting proof of the grandparent's Portuguese citizenship, the intermediate parent's birth certificate, and your own birth certificate — all in the full Narrativa/Inteiro Teor format, apostilled and translated. This goes to the Conservatória dos Registos Centrais or the Portuguese consulate.

Third Generation and Beyond

Citizenship by descent does not transmit automatically beyond the second generation. Great-grandchildren of Portuguese citizens are not entitled to citizenship through bloodline alone. They would need to qualify through another route — typically naturalization (which requires residency) or the Sephardic route if applicable.

The "Loss of Nationality" Complication

If your Portuguese ancestor voluntarily renounced Portuguese citizenship to take another nationality under older laws (pre-1981 or under certain pre-2006 rules), that may have severed the transmission chain. Whether a specific historical renunciation breaks the chain depends on the law in force at the time of renunciation and subsequent legal changes. Cases involving ancestors who renounced Portuguese nationality in the early and mid-20th century under colonial or authoritarian-era rules often benefit from specific legal analysis.

The Sephardic Route: Status After the 2024–2025 Reforms

The Sephardic route was introduced in 2015 under Law 30/2015 as a historical reparation for the expulsion of Jewish communities from Portugal in 1496. It allowed descendants of Portuguese Sephardic Jews to obtain citizenship without residency or language requirements, by demonstrating Sephardic ancestry and connection to the Portuguese Sephardic community.

The program attracted significant interest — and significant controversy. By 2023–2024, reports of fraudulent applications, questionable community certifications, and a lack of rigorous genealogical verification led to a major legislative overhaul.

What Changed in 2024 and 2026

Stricter genealogical proof: The reformed rules (Law Orgânica 9/2024 and subsequent regulations) significantly tightened what counts as acceptable evidence of Sephardic Portuguese ancestry. Vague family oral histories and generic Sephardic community documentation are no longer sufficient. Applicants must demonstrate a specific genealogical connection to communities of Sephardic Jews who were present in Portugal or its territories before 1496.

Community certification scrutiny: The role of the Jewish communities in Portugal (particularly the Jewish Community of Porto and the Lisbon Jewish Community) in certifying applicants was reformed. The criteria for certification are more strictly defined, and the government review of certifications is more rigorous. Cases where community certificates were issued without adequate genealogical verification are being re-examined.

Ongoing applications: Applications filed before the 2024 reform that were still pending are being reviewed under the new standards. Some have been approved; others have been suspended pending additional evidence.

No new open pathway for speculative applicants: If you don't have documented Sephardic Portuguese ancestry with specific genealogical evidence traceable to pre-1496 Portugal or its territories, the reformed route is effectively closed to you. The days of obtaining a Sephardic community letter and Portuguese citizenship without rigorous proof are over.

Who This Route Is Still Open For

The Sephardic route remains available for people who:

1. Can trace genealogical ancestry specifically to Sephardic Jewish communities expelled from Portugal (not just from Spain or the broader Sephardic diaspora in the Ottoman Empire, North Africa, or elsewhere — Portuguese connection specifically is required)
2. Have documentary evidence of this ancestry — genealogical records, community records, gravestones, surname evidence consistent with Portuguese Sephardic origin
3. Can demonstrate a connection to the Portuguese Sephardic community (cultural, religious, or genealogical)

Sephardic Jewish families in the Americas, the Caribbean (especially Curaçao, Jamaica, and Suriname), North Africa, Turkey, Greece, and the Netherlands often have documented Portuguese Sephardic roots traceable to the 1496 expulsion. For these families, the route remains available with proper documentation.

The Application Process for Sephardic Route

Applications go through the same Conservatória dos Registos Centrais as naturalization applications. You need:

• A certification letter from one of the recognized Portuguese Jewish communities (Porto or Lisbon) confirming your Sephardic Portuguese ancestry
• Genealogical documentation supporting the claim
• Proof of connection to the Portuguese Sephardic community
• Standard identity and criminal record documents

The government fee is €250, same as other nationality routes.

Given the reform climate, legal representation from a lawyer who specializes specifically in the Sephardic route and understands the current evidentiary standards is strongly advisable. Generic immigration lawyers who handled these applications under the pre-2024 system may not be current on the reformed requirements.

Practical Advice for Ancestry Applicants

Get professional genealogical research done first: Before spending money on legal fees or document procurement, establish whether you actually have a viable claim. For descent claims, this means locating your Portuguese ancestor and verifying their nationality records. For Sephardic claims, it means researching whether your specific family history connects to Portugal specifically.

Use Portuguese consulates for overseas registration: If your Portuguese ancestor's nationality was never registered in the system, you cannot claim citizenship through them even if the legal right exists. Registration can be done at any Portuguese consulate. This is often the first practical step for descent applicants abroad.

The residency requirement does not apply: Both the descent and Sephardic routes do not require you to have lived in Portugal. You do not need a Portuguese address, a NIF, or a residency card to apply through these pathways. This distinguishes them entirely from the naturalization route.

Language requirement: The descent and Sephardic routes do not impose the standard A2 language requirement that naturalization applicants face. However, having some evidence of connection to the Portuguese language or community can support the "effective connection" assessment for grandchildren applications.

The Portugal Citizenship Guide at /pt/citizenship focuses primarily on the residency naturalization route — which is the applicable path for the vast majority of readers who have been living in Portugal on a visa. If your situation involves descent or Sephardic ancestry specifically, the guide covers the foundational documents and the application channel, and recommends specialist legal counsel for the genealogical verification component.
