Citizenship in Portugal
- Eligibility
- THIS ROUTE IS SUPERSEDED. The 6-year consolidation rule under Art 12-B was the governing standard from the entry into force of LO 2/2018 (06 July 2018) until the day before LO 1/2026 came into effect (18 May 2026). From 2026-05-19 onward, the applicable consolidation threshold is 10 years (PT-NAT-12B-CONSOL).

Overview
THIS ROUTE IS SUPERSEDED. The 6-year consolidation rule under Art 12-B was the governing standard from the entry into force of LO 2/2018 (06 July 2018) until the day before LO 1/2026 came into effect (18 May 2026). From 2026-05-19 onward, the applicable consolidation threshold is 10 years (PT-NAT-12B-CONSOL).
Why preservation matters: The Sephardic naturalisation programme generated thousands of grants between 2015 and 2022. Many of those grants are within the 6-to-10-year window in 2026. Whether a family who derived nationality from a fraudulent 2016 Sephardic naturalisation (10 years elapsed = 2026) benefits from the bar under the 6-year W5 rule or the 10-year W7 rule depends on which transitional regime governs the specific cancellation proceedings. This cannot be resolved without knowing whether those proceedings were initiated before or after 2026-05-19.
Who qualifies
Same structural criteria as the current rule (PT-NAT-12B-CONSOL) but with a 6-year threshold:
- Original naturalisation obtained by fraud/misrepresentation.
- 6 years (not 10) elapsed from registration date.
- Bona-fide third-party derivative nationals exist.
- Cancellation would prejudice their nationality status.
Requirements
None — Art 12-B is a procedural defence in cancellation proceedings, not an application pathway. The 6-year version operated identically to the 10-year version in procedural terms; the sole difference is the time threshold.
How to apply
Identical to the current Art 12-B (PT-NAT-12B-CONSOL) — this was a procedural defence asserted in cancellation proceedings before IRN/CRC administratively and administrative courts / STA judicially.
Legal basis
The structural operation was identical to the current rule: (1) fraud by the acquirer; (2) 6 years elapsed from registration; (3) bona-fide derivative third parties exist; (4) cancellation would prejudice them. The fraudulent acquirer was not protected under the 6-year version either.
The 6-year period was confirmed operative in court by TCA Sul Acórdão Proc. 2854/11.6BELSB (02-09-2023), which applied Art 12-B in a decolonisation-era historical case.
LO 1/2026 doubled the threshold to 10 years. The proposed Art 12-B n.3 "manifestly fraudulent" (manifesta fraude) carve-out — which would have removed Art 12-B protection even after the consolidation period in cases of manifest fraud — was struck by TC Acórdão 1133/2025 (Proc. 1383/2025, 15-12-2025, DR Série I n.º 2, 05-01-2026) before enactment. LO 1/2026 was enacted without it.
Example scenarios
Proceedings initiated in January 2026 — BEFORE 2026-05-19 EIF of LO 1/2026. Therefore the 6-year W5 rule governs. 9 years 7 months > 6 years: the Art 12-B bar operates. Tiago is a bona-fide third-party derivative. Cancellation is barred as to Tiago's nationality. Rui's own naturalisation remains subject to cancellation. This is a W5-rule scenario even though the factual timeline extends into 2026.
The operative rule is determined by the date cancellation proceedings are initiated relative to LO 1/2026 EIF. January 2026 is pre-EIF, so the 6-year threshold applies (LO 2/2018 redação, preserved under LO 1/2026 Art 7 transitional). The 6-year threshold is met; bona-fide third-party condition is met.
For proceedings initiated before 2026-05-19: the 6-year W5 rule (PT-NAT-12B-CONSOL-W5) governs. For proceedings initiated on or after 2026-05-19: the 10-year W7 rule (PT-NAT-12B-CONSOL) governs. The exact initiation date of each specific cancellation proceeding is the pivot. Families of 2016-2018 Sephardic naturalisations who had derivative nationals in good faith and whose cancellation proceedings were initiated before 2026-05-19 at 6+ years: protected under W5 rule. Same families but proceedings initiated after 2026-05-19: need 10 years (may not yet be met for 2018 naturalisations in 2026).
This scenario illustrates the practical importance of maintaining the W5 closed-window record. Both the 6y and 10y figures are correct for their respective eras. Conflating them would produce incorrect legal analysis for affected families.
