The four minor routes: which one is your child's?

The IRN's official list of application types contains four entries beginning with the word «menor» — minor — and they are not four flavours of one application. One of them, «minor whose parent acquired Portuguese nationality after they were born», is not a naturalisation at all: it asks for no birth in Portugal, no residence, no schooling. The other three ask for all of that, starting with a condition the entry's own name never mentions: the child must have been born on Portuguese territory.

That single fact settles most cases in two minutes. If your child was born abroad, three of the four entries disappear and one remains. If the child was born in Portugal, the question becomes which of the three you can actually prove — and since 19 May 2026 the answer has changed, because the statute stopped letting you pick one. If you are also preparing your own application, the guide to the CIPLE and the citizenship test covers the part that is yours alone; this page is about the children's.

Why the form shows four boxes and the statute has two routes

The confusion is a formatting accident. The four entries sit one under another, same typeface, same list, looking like comparable options you choose between on convenience. They are not comparable.

One is an acquisition by declaration: the legal representatives declare that the child wants to be Portuguese, and the basis is simply that a parent acquired the nationality. The other three are naturalisation — an application to the Government, which assesses requirements and can refuse. The first is short and light on documents; the others involve criminal record certificates and proof of residence. Picking the wrong entry is not a labelling slip. It puts the file into the wrong procedure.

The route that skips naturalisation entirely

«Minor or legally incapable person whose parent acquired Portuguese nationality after their birth» is article 2 of the Nationality Law, and that article is a single sentence: no paragraphs, no sub-paragraphs, no cross-references. The 2026 reform did not touch it — the amending statute lists the articles it rewrote, and this one is not on the list.

Two practical consequences. There is no requirement that the child was born in Portugal; the child may never have set foot there. And there is no residence, schooling or language requirement, because a one-sentence article hides nothing. What matters instead is the date your own acquisition was registered, which is a different page: I became Portuguese — what about my minor children? walks that route end to end.

Three of the four require birth in Portugal

The remaining three entries — parent resident «regardless of permit» for five years, parent holding legal residence, and one school year attended by the child — all come from one place. They are the three alternative conditions that the Nationality Regulation still sets out today, under a heading the IRN list does not reproduce: «Naturalisation of minors born on Portuguese territory».

That heading eliminates more applicants than anything else on this page. None of the three works for a child born in Brazil, Angola or Ukraine, however many years of residence the parent has and however many school years the child has completed in Portugal. Birth in Portugal is the door; the three conditions are only different ways of showing the family is rooted there.

What each box asks you to prove

The Regulation spells out, in one sub-paragraph, what goes with the application in each case. Read the right-hand column before choosing: plenty of families hold the proof of one condition in a drawer at home and spend months chasing the proof of another.

What changed on 19 May 2026

Until 18 May 2026 the statute required the minor to satisfy one of the three conditions. That was a genuine choice, and it is the choice the IRN list still mirrors with three separate entries. The wording in force since 19 May 2026 changes the word the whole sentence hangs on:

Three differences, all of them tightenings. «Cumulatively» replaced «one of the following conditions» — there is no longer a choice. «Legal residence» replaced «regardless of permit», so presence evidenced by a parish-council certificate no longer suffices for the parent. And the five years now run on legal residence, not on mere presence. Schooling, which used to be a standalone route, is now one condition among the others, and is phrased as current enrolment and regular attendance rather than a year completed in the past.

One discrepancy, stated with the care it deserves: the Regulation still lists the three conditions in the alternative, because it has not been amended since 2022. The reform gave the Government 90 days to align it — a deadline that fell on 16 August 2026 with no amendment published. The statute prevails over the regulation, but the body that decides how any given file is framed is the Conservatória dos Registos Centrais, not this guide. It is also why the IRN list still makes sense: there are files to which the old wording genuinely applies.

If the application was already filed, the old choice stands

This is the part that changes decisions, and it is written down rather than inferred. The reform contains a transitional rule directing that administrative procedures pending when it came into force continue to be governed by the previous wording.

1. Up to 18 May 2026

   Application filed: one of the three conditions was enough, and parental residence counted regardless of permit.
2. 19 May 2026

   The reform enters into force. New applications must meet the cumulative requirements.
3. After 19 May 2026

   Files already lodged continue to be assessed under the old wording, by force of the transitional rule.

If you filed before that date and later received a request for documents that looks like it belongs to the new statute, it is worth replying with the file number and the filing date on the face of the letter. How the transitional rule works, and what to do when a counter ignores it, is in what changes for applications already submitted.

At 16, one more requirement appears

The age of criminal capacity in Portugal is 16, and from that birthday a minor stops being exempt from everything. Under the old wording, a minor in that band had to meet two requirements: no conviction of the kind described there, and no danger or threat to national security. The wording in force widens the cross-reference to four sub-paragraphs, and one of them is new for this age band — the solemn declaration of adherence to the fundamental principles of the democratic rule of law. A check against United Nations and European Union restrictive measures joins it.

What stays outside, and is the question people ask most: the knowledge requirement — the language, culture, history and national symbols the test exists to examine — is not among the sub-paragraphs the statute cross-refers to for minors. Minors and the citizenship test takes that cross-reference apart paragraph by paragraph, including the trap of turning 18 mid-application.

The procedure is free, and it is worth knowing why

The statute says in terms that the naturalisation procedure for the minors covered by that paragraph is free of charge. It is not a discount or an exemption to be applied for: the law declares it, and it covers stateless applicants and children in institutional care under a promotion-and-protection measure as well.

That last situation has no entry of its own on the IRN list, and deserves saying out loud: where a definitive promotion-and-protection measure is in place, it falls to the public prosecutor to bring the naturalisation, and the statute directs that the best interests of the child be weighed. People working in child protection rarely find this written down where they go looking.

Choosing, in five minutes

In order, without skipping. One — is a parent already Portuguese by acquisition, with the registration done? If so, the route is the declaration and the other three do not arise. Two — was the child born on Portuguese territory? If not, none of the three minor naturalisation routes is available, and the family's path lies elsewhere. Three — is the application already filed? If it is, the old wording governs it and the condition you invoked still holds. If it is not, prepare all three: five years of the parent's legal residence, enrolment and regular attendance, and the criminal record certificates if the child has turned 16.

If, having got this far, your remaining doubt is which of the twenty-odd entries on the list matches your own situation rather than your child's, the guide to the IRN application types walks the whole list, entry by entry. And if what you are facing is the test itself, the free simulator gives you an honest sense of where you stand without paying to find out.
