I became Portuguese — what happens to my minor children?
The short answer is a good one, so here it is first: your minor children do not repeat your process. No civic test, no language exam, no seven or ten years of residence. The statute gives them a route of their own, exercised by a declaration made through their legal representatives — usually you — and it exists precisely because you became Portuguese. It is the shortest route in the Nationality Act.
What separates a family that settles this in weeks from one that spends months on it is almost never the law. It is the calendar. Your children's door opens on the day your acquisition is registered, not on the day you are told it was granted — and those two dates can be months apart. If your own application is still in motion, start with the timelines under the new nationality law, because your registration is what starts everything else.
- The children's route fits in one sentence of the statute: they may acquire nationality by declaration, because a parent acquired it.
- There is no knowledge requirement on this route — no civic test, no language proof, no residence period.
- The 2026 reform did not touch this article: the amending law lists the articles it rewrote, and this one is not on the list.
- The declaration must identify the parent's registration — which is why registration, not the decision, is what opens the door.
- A declaration counts as filed on the day it reaches the Central Registry in Lisbon, whichever counter you hand it in at.
- The public prosecutor may oppose within two years of registration. That is the one real risk on this route.
One institutional point, because it saves a wasted trip
Nationality is registry business, not immigration business. It is filed with the civil registry — the Central Registry Office in Lisbon, its extensions, any civil registry office, or a Portuguese consulate. The agency that handles residence permits does not handle this and cannot advise on it. English-language forums mix the two constantly, and the cost of the confusion is a wasted appointment.
The whole law on this fits in one sentence
That is not a figure of speech. The article that creates this route is a single paragraph, with no sub-paragraphs and no cross-references:
«Minor or legally incapable children of a father or mother who acquires Portuguese nationality may also acquire it, by declaration.»
Notice what is not there. Not «provided they live in Portugal». Not «provided they show sufficient knowledge of the language». Not «provided they are old enough to sit the test». A one-paragraph article does not hide conditions: if a condition is not in the text, it is not on this route. Everything people associate with Portuguese citizenship — legal residence, knowledge of the language and culture, means of subsistence — lives in the naturalisation article, and naturalisation is a different path with a different procedure.
A vocabulary note that changes the reading: the Regulation no longer says «incapable», it says «adults under an accompaniment regime who need representation for the act». Same idea, updated to Portugal's reform of legal capacity. An adult child who needs representation fits here exactly as an eight-year-old does.
The 2026 reform did not touch this route
This is the question that brings half of our readers here, and it deserves an answer you can verify in two minutes rather than a promise. The Organic Law that rewrote Portugal's nationality statute in May 2026 does what such laws do: it opens with an article listing, one by one, the articles it amends. That list includes the naturalisation requirements, marriage, adoption, opposition and the waiting periods. The minor-children route is not on it.
The distinction matters more than it looks. A consolidated text — the kind you read on legal databases — shows the law as it stands today and says nothing about the age of each sentence: an article from 1981 and an article rewritten three months ago are typeset identically. A reader looking for confirmation always finds confirmation. The amending law's own list of articles is what dates the text, and it is free to check.
So the test really does not reach my child?
It does not. And not by way of exemption — by way of architecture. The knowledge test lives inside the naturalisation requirements, the process where the government grants nationality to an adult who meets a cumulative list of conditions. The children's route is acquisition by declaration of will: you declare, you do not petition for a grant. The test was never part of their process, which is a different thing from their being excused from it.
That has a practical consequence: there is nothing to justify, no certificate to attach, no minimum age to argue about. For the full map of who does and does not pass through the knowledge requirements, see who is exempt from the test; for the routes a child would have in their own right, independently of you, see do children have to take the test?
The date that counts is the registration
Here is the most expensive calendar mistake on this route, and it is an easy one to make. The statute says changes of nationality take effect only from the date the underlying acts are registered. And the Regulation requires the child's declaration to identify the parent's registration of acquisition. So until your registration exists, there is nothing to identify and your child's declaration has no foundation to rest on.
In practice, the parent who gets the approval notice and rushes in the next morning with the children's paperwork is ahead of the document they need. The right order is: your registration is entered at the Central Registry, you can now identify that registration, and only then is your children's declaration complete. You do not need to wait for your citizen card — you need to wait for the registration, which comes earlier and is a different thing.
How it is actually filed
The declaration is made by the minor's legal representatives. It can be made in person and orally — at the Central Registry Office, its extensions, any civil registry office, or a Portuguese consulate, where it is taken down as a formal record. Alternatively it can be filed electronically, or on an approved form handed in at one of those counters or posted to the Central Registry Office.
One detail earns its place here: whichever counter you use, the declaration counts as filed on the date it is received at the Central Registry Office in Lisbon. Handing it to a consulate in September does not fix September. If you are counting days — because a birthday is approaching, say — count from receipt, and keep your proof of submission.
If something is missing, summary refusal is decided within 30 days, and before that you are notified of the grounds and given 30 days to respond. It is not a final rejection: it is a warning with a clock, and answering inside the clock resolves most cases.
Documents: fewer than you fear
The general rule is unremarkable — you attach what proves the facts the acquisition depends on — but the exceptions are where the time is saved. Applicants are excused from producing registry certificates the service can obtain itself, as long as they give enough detail to identify the records: place and date of birth and, if known, the office holding them. The Portuguese criminal record is obtained by the registry directly.
On translations, the rule is more generous than its reputation: documents written in English, French or Spanish may go untranslated if the registrar does not require a translation. Outside those three languages, translation must be made or certified as the law provides. Foreign civil-registry certificates are legalised under the general rules — the full checklist, with apostilles and consular legalisation, is in the documents you actually need.
On cost: the Regulation sets no figure. It refers fees to the Registry and Notary Fees Regulation, a separate instrument that is updated on its own schedule. We are not printing a number we could not confirm at the official source today — ask for the current amount at the counter where you file, and be sceptical of anyone who quotes it from memory.
The real risk is called opposition
If this route has a weak point, it is not the entrance — it is what can follow. Acquisition by declaration of will, and the children's route is one, is open to opposition by the public prosecutor, filed within two years of the date the acquisition is registered. The principal ground, in the wording the 2026 reform gave Article 9, is the absence of genuine ties to the national community, assessed against the substantive parameters drawn from the naturalisation requirements.
Note what that does and does not mean. It does not mean your child now has to sit the test: opposition is a prosecutor's proceeding, not an entry requirement, and it runs after registration rather than before. It does mean the family's connection to Portugal can be examined inside a two-year window, and that the examination now looks at more concrete parameters than the old formula did. How that connection is proved is covered in proving effective connection, and what to do if something goes wrong in a refused application and how to appeal.
What to do, in order
First confirm that youracquisition is registered, not merely approved. Keep the registration details, because that is what your children's declaration will identify. Gather each child's birth certificate, and do not rush to order certificates the registry can fetch itself. Choose the counter for convenience, knowing the date that counts is arrival at the Central Registry Office. And if your own application is still running, finish that first: on this route, hurrying the second step does not make up for the missing first one.
