Missing Documents and 'Absence of Legal Requirements': the IRN Names What Sits Behind 3,312 Preliminary Nationality Refusals

The Instituto dos Registos e do Notariado (Institute of Registries and Notaries, IRN) has named the reasons behind the thousands of preliminary refusals now landing on Portuguese nationality applications. Asked to explain them, the institute listed four: "absence of legal requirements, lack of documents, errors and divergences found."

The scale sits in the Justice Ministry's own balance sheet, published on 19 August. Since taking up post on 1 July, the dedicated nationality teams have issued 3,312 preliminary refusal notices in applications based on time of residence, the route most foreign residents use. Those same teams handed down 1,240 final decisions, prepared 623 files on children of Portuguese nationals for decision, and confirmed 1,258 cases under the Estatuto de Igualdade de Direitos e Deveres (Statute of Equal Rights and Duties) that Portugal and Brazil share.

A preliminary refusal is not the end

The distinction matters, and it is easy to miss when the letter arrives. A minuta de indeferimento is a draft decision, not a closed file. The IRN confirms that applicants are notified and given a window to respond in writing, and the period fixed in law is 30 days.

In practice that makes the refusal notice an invitation to fix the record: to supply the missing certificate, correct a divergence between documents, or argue that a requirement the conservatória believes is unmet has in fact been satisfied. Missing the window is what turns a draft into a decision.

The requirements nobody has explained yet

Sitting behind the volume is a gap the government has not closed. The rewritten nationality law has been in force since May, and the legal deadline for the regulation that is meant to make it operable has expired without one appearing.

Applicants are therefore facing requirements with no instructions. The text obliges anyone seeking naturalisation to prove sufficient means of subsistence, but no minimum figure has been published and no list of acceptable documents exists. The same is true of the requirement to demonstrate knowledge of the fundamental rights and duties attached to Portuguese nationality and of the political organisation of the Portuguese state, and of the new solemn declaration of adherence to the founding principles of the democratic rule of law.

The law that created those tests is the one President Seguro promulgated in May, which doubled the residence requirement to ten years for most non-EU applicants and set seven for EU and CPLP nationals.

The staffing argument underneath

Forty-one people work the nationality queue full time, 28 at the Conservatória dos Registos Centrais (Central Registries Office) in Lisbon and 13 at the Arquivo Central in Porto, in post since 1 July. On the Equal Rights Statute for Brazilian citizens, the ministry says that intervention pulled the processing line forward by roughly four months, from the second half of November 2025 to the second half of March 2026.

The registry workers' union reads the same period differently. The STRN counts a shortfall of 270 conservators and 2,731 registry officials, and notes that the number of conservatórias running late rose from 220 to 237 between May and June. It has also accused the IRN of dropping the national totals from its monthly statistics. The ministry counters that the recovery plan launched into a general strike, a sector strike and the summer holiday period, and points to 113 new conservators this year, 47 of whom started in August and 66 due in September, with 485 registry officials arriving in the final quarter.

What This Means for Expats

• If a refusal notice arrives, you have 30 days. The response is made in writing to the conservatória, and it is the stage at which missing documents and inconsistencies can still be cured.
• Check your documents against each other, not just the checklist. "Errors and divergences" is one of the four reasons the IRN gives. Names, dates and places that differ between a birth certificate, a passport and a residence permit are a common cause.
• The means-of-subsistence test has no published threshold. Until the regulation appears, there is no official figure or document list. Keep the fullest evidence you can, and expect the standard to be set retroactively.
• Files are moving faster than they were. The Equal Rights Statute line advanced about four months in a single quarter, which is the clearest sign so far that the dedicated teams are having an effect.
