Nationality application refused: what to do, and by when

If a decision refusing your Portuguese nationality application has arrived, the first useful thing to do is not to write anything. It is to look at who signed it. The Nationality Regulation — Decreto-Lei 237-A/2006, republished in full as an annex to Decreto-Lei 26/2022 of 18 March, which is the version quoted throughout this guide — provides for two different refusals, at two different stages, and they are not challenged the same way or within the same deadline. Treating one as the other is the most common way of losing the right to react without noticing.

One institutional point before anything else, because English-language forums muddle it constantly: nationality is decided by the Instituto dos Registos e do Notariado and the Ministry of Justice, not by AIMA. AIMA handles residence permits. If you are earlier in the process than this article assumes, start from the guide to the language requirement and the application process.

1. Up to 30 days after filing

   Summary rejection is possible — only for three formal reasons: missing elements, missing documents, or an electronic filing outside the rules.
2. Before any decision

   Prior hearing: you are notified of the grounds and have 30 days to respond. Responding does not cost you time — it suspends the deadline clock.
3. End of the review

   An opinion within 45 days; if unfavourable, a final decision by the member of government, notified to you.
4. After the decision — complaint

   15 days to complain to the author of the act; 30 days for them to decide.
5. After the decision — hierarchical appeal

   30 days, only if there is a hierarchical superior above whoever signed.
6. After the decision — judicial challenge

   One year against a final refusal; against a summary rejection, the general CPTA deadlines, not the one-year window.

Two different things are both called «refused»

The first is summary rejection — indeferimento liminar. Article 27(2) of the Nationality Regulation gives the Conservatória dos Registos Centrais 30 days from receiving the file to review it summarily and reject it on three grounds, and only those three: the application lacks the elements needed to identify it; it is not accompanied by the documents needed to prove the facts the claim rests on; or an electronic filing was not made in the terms of its own ministerial order.

Notice what is missing from that list. Not enough residence, insufficient language, an unconvincing connection to Portugal — none of it is there. Summary rejection is a decision about the form of your application, and it is signed by a registrar.

The second is the final refusal. Once the investigation is done, an opinion on whether the legal requirements are met is issued within 45 days; if it is unfavourable, the file goes to the member of Government responsible for justice for decision. That decision, not the opinion, is what refuses your application, and the same rule requires that it be notified to you.

Before the decision: the 30 days that belong to you

In both cases the administration cannot refuse you without hearing you first. Article 121(1) of the Administrative Procedure Code gives interested parties the right to be heard before the final decision, and to be told what that decision is likely to be; the same code sets the floor for the reply window at «not less than 10 days».

The Nationality Regulation is more generous: 30 days, both for summary rejection and for an unfavourable internal opinion — and the notice must tell you how to inspect the file.

Two practical consequences. First, that letter is a warning, not a decision, and it is by far the cheapest stage of the whole matter: a missing certificate costs postage, not litigation. Second, the Code states that holding the hearing suspends the running of deadlines in all administrative procedures. The time you spend answering is not time you lose.

After the decision: three doors, three different clocks

A complaint to the author of the act — reclamação. The Code allows it against the practice or omission of any administrative act, within 15 days where no other deadline is fixed by law. The body has 30 days to rule, and may confirm, revoke, annul, amend or replace its own act.

A hierarchical appeal — and here is the trap. Article 193(1)(a) allows it against acts of bodies that are subject to the hierarchical powers of another body, addressed to the highest superior of the author of the act. A minister's decision has no hierarchical superior; a registrar's does. There is also a middle case worth checking before you choose: article 28 of the Regulation lets the member of Government delegate naturalisation competences to the president of the IRN's board, with power of sub-delegation — and someone deciding under delegation is not the top of the ladder. This is why the signature is the first thing to read. Where the appeal is a mandatory one, the deadline is 30 days.

Judicial challenge, before the administrative and tax courts. It is the only route that does not depend on the goodwill of the body that already said no.

The one-year deadline, and the exception to it

Nationality litigation has its own rule, and it is unusually generous. Article 61(1) of the Regulation grants standing to challenge acts and omissions in attribution, acquisition or loss of nationality proceedings within one year, to anyone claiming a direct and personal interest and to the public prosecutor — «except as regards the judicial challenge of summary rejection».

That final clause is why the distinction at the top of this article is not academic. Paragraph 2 sends summary rejection to the administrative and tax courts under the Code of Procedure in the Administrative Courts, which means that Code's own deadlines rather than the one year. The Regulation adds that judicial challenges of nationality acts follow the terms of the ordinary administrative action.

Usable version: against a final refusal there is a one-year deadline written into the Regulation; against a summary rejection, do not count on it. Exactly which deadline of the CPTA applies to your case is the kind of question no article should answer by eye — count from the date of notification and treat it as urgent.

Does a complaint freeze the decision?

Article 189 of the Administrative Procedure Code separates two situations that forums always merge: mandatory administrative challenges suspend the effects of the act (189(1)), while optional ones have no suspensive effect unless the law says so or the body itself accepts that immediate execution would cause irreparable harm (189(2)).

The uncomfortable reading is the honest one: filing a complaint does not automatically freeze anything, and while it is being considered the court clock keeps running.

A prosecutor's opposition is not a refusal

A third kind of letter arrives and gets read as a refusal while being something else entirely. Instead of refusing, the State may lodge opposition to the acquisition of nationality — which is not an administrative act but a court action. Article 57(9) of the Regulation says the public prosecutor lodges opposition before the administrative courts; the same provision has the defendant summoned to contest, with no further pleadings or written submissions, and says what happens if the opposition succeeds — cancellation of the nationality register, if one has already been drawn up.

Three differences matter. There is no administrative deadline to meet here; there is a court summons. The decision is a judge's, not an official's. And the target can be a registration that already exists — opposition can arrive after you are Portuguese on paper. The grounds themselves live in the Nationality Act and deserve their own article; what matters here is not to treat a summons as if it were a letter from the registry.

Where a lawyer stops being optional

We cannot give you legal advice and will not pretend otherwise. What can be said, with the statute open, is where the nature of the problem changes.

Answering a prior-hearing notice means attaching documents and explaining facts. It is the stage most people handle alone, and it is also the stage where the law gives you the most time (30 days) and the most information (the likely direction of the decision, and how to inspect the file). A complaint or a hierarchical appeal is still writing to the administration.

Once the route is a judicial challenge, it stops being a form: it runs in an administrative court, follows the ordinary administrative action governed by the CPTA, and is subject to deadlines that expire. If you are at that point — or if you have been summoned because the prosecutor lodged opposition — the cost of one consultation is smaller than the cost of miscounting a deadline. And it is worth remembering what we have already written about what the process costs and who actually runs it: the fees you paid do not come back because the application failed.

Can I simply apply again?

None of the provisions above forbids a fresh application, and after a summary rejection that is often the shortest path: if the file fell over a missing document, filing again with the document solves the same problem without a court. What cannot be claimed is that it is free — it is a new procedure, with a new procedure's fees.

Where the refusal went to the merits, filing the identical file again has the identical answer waiting for it. The useful question there is not «should I reapply?» but «what has changed since?».
