- § NOTE: this is a NATURALIZATION path, not a jus-sanguinis attribution path. Art. 1(1)(d) of the republished Lei 37/81 caps the attribution chapter at the 2nd degree (grandchildren). Great-grandchildren receive no standalone descent/attribution route.
- § NEEDS-VERIFICATION (Regulamento): the specific CIPLE level required by Art. 6(1)(c) for Art. 6(8) applicants is set in Decreto-Lei n.º 237-A/2006 (Regulamento da Nacionalidade Portuguesa). Lei Orgânica 1/2026 Art. 4 mandates a Regulamento amendment within 90 days of publication (deadline ~16 August 2026). That amendment was NOT published as of 28 May 2026. Do NOT assume CIPLE B1 or any specific level until the amended Regulamento is published.
