Portuguese Citizenship by Marriage: Requirements, Process & Timeline

What are the requirements for Portuguese citizenship by marriage?

Four things: the relationship and its length, a connection to Portugal, a clean criminal record, and a marriage that exists in the Portuguese registry.

Put simply, you need to be married to a Portuguese citizen (or in a recognized de facto union) for three years, prove an effective connection to the community unless you are exempt, clear the criminal check, and have your marriage certificate registered in the civil registry before your citizenship application is assessed.

Miss any one and the Conservatória issues a formal request for correction, an exigência. That is where most timelines quietly stall, so it pays to get all four right before you file.

Here is each requirement in turn.

The three-year rule

The clock is three years, counted from the date of the marriage or from the judicial recognition of a de facto union.

There is no upper limit and no extra age requirement beyond those three years. Same-sex spouses have identical rights, with the same documents and the same process, since Portugal has recognized same-sex marriage since 2010.

What counts as a de facto union?

A de facto union (união de facto) is unmarried cohabitation, and it qualifies on the same three-year timeline as marriage, with one extra step.

You first need a Portuguese civil court to recognize the union. If the union was formed abroad, that foreign status usually has to be reviewed and confirmed by a Portuguese court before you can apply. Only then does the three-year clock help you.

!: Most people highlight the hardships of going through Portuguese court to recognize the union, and recommend marrying for the sole purpose of facilitating the citizenship, if this is your main priority.

Does the marriage have to be ongoing?

Yes, at the moment you declare. The marriage or union must be valid when you submit your declaration.

That is the only live-relationship condition. After your acquisition is registered, a later separation does not undo it.

Proving your effective connection to the Portuguese community

This is the heart of the route since May 2026, and the part that gets applications from couples living entirely outside Portugal scrutinized.

Alongside the three years, you normally have to show an effective connection to the Portuguese community (ligação efetiva à comunidade nacional). The idea behind it is simple: the law is testing whether the bond to Portugal is genuine, not a paper marriage.

The good news is that the law lists situations where this connection is presumed, so you skip the separate proof entirely.

When is the connection recognized automatically?

Under the current rules, you are exempt from proving your connection if any one of these is true.

If one of these fits, your eligibility on the connection point is settled and you move on.

What counts as proof if you are not exempt?

If none of the presumptions fit, for example an American married three years and living in the US, you document the connection yourself, with concrete evidence.

Portuguese consulates point to the kinds of proof that count: family, social, economic, and professional ties, plus language, culture, and time spent in Portuguese communities.

In practice, that can include:

• Portuguese language study or a certificate (more on the CIPLE below)
• Membership in Portuguese clubs or cultural associations, including ones in your home country, which consulates explicitly accept
• Regular visits to Portugal, with dates
• Property, business, or economic links to Portugal
• Family ties to Portuguese citizens beyond your spouse
• The handwritten letter option: a letter, in Portuguese, explaining your reasons for wanting nationality, which the consular route accepts as a form of language evidence when you have been married under five years

The honest advice from people who have been through it: start building and documenting these ties from day one, not in the final months before you file. The bar rose in 2026, and a connection you genuinely built over years is far easier to show than one assembled in a hurry.

What did the 2026 law change for spouses?

It kept the three-year rule but sharpened the connection test and extended the criminal bars.

Based on the text published in the Diário da República, three things changed for the marriage route:

• The connection test now points explicitly to the wider integration criteria used for naturalization: knowledge of Portuguese language, culture, history, national symbols, fundamental rights and duties, and the political organization of the state.
• The criminal and security bars now reach even the exempt cases. A marriage over six years or common Portuguese children still removes the connection test, but a serious conviction or a security concern can now block the application anyway.
• The Public Prosecutor (Ministério Público) can formally oppose your acquisition after the fact.

Can the state refuse or oppose your application?

Yes. Even after you meet the requirements, the Public Prosecutor can raise an opposition on specific grounds.

The main ground is the absence of an effective connection to the community, now measured against those integration criteria. The Public Prosecutor has a window of two years from the date your acquisition is registered to act. This is why a thin connection file is risky even when you technically qualify: approval is not always the last word.

A clean criminal record

You need a criminal record certificate from your country of birth, your country of nationality, and every country where you have lived for more than a year after the age of 16.

Each one has to be apostilled and translated into Portuguese if it is not already, and it generally has to be recent, issued within three months before you file. (Applicants in the US, for instance, need the FBI Identity History Summary Check, apostilled, rather than a state or local police report.)

You will not need a Portuguese police record yourself; the authorities pull that one on their own.

The bar itself: a conviction carrying an effective prison sentence of three years or more for the serious offences listed in the law can block the application. Since 2026, that bar applies to the marriage route too.

A marriage registered in Portugal

Your marriage has to exist in the Portuguese system before your application can be assessed.

If you married abroad, that means transcribing the marriage first. We cover exactly how in the documents section, because it is a step, not just a box to tick.

Does it matter how your spouse became Portuguese?

Yes, and it can decide whether a marriage that predates their citizenship even counts.

Either type of spouse gives you the right, since a "Portuguese national" in the law means any Portuguese citizen, whether they hold it by origin or by acquisition. What changes between the two is how your three years are counted.

If your spouse is Portuguese by origin (attribution)

Someone Portuguese by origin is treated as Portuguese from birth, even if the paperwork was only recognized recently.

Under Portuguese law, nationality of origin takes effect from the date of birth, not the date it was registered. The recognition is retroactive: in the eyes of the law, they were always Portuguese.

The practical result for you is that the whole marriage counts, including the years before their nationality was formally recognized. If your spouse is a child or grandchild of a Portuguese citizen, this is the route they hold, and your marriage duration is safe.

One point trips people up here, and it is about the paperwork order, not the marriage date. You can only file once your spouse has their Portuguese birth record and your marriage is registered against it, which means they finish their own process first. The date of the marriage still counts from the day you married. You just cannot apply before their record exists. That gap is where the myth that "the marriage only counts if you marry after they become Portuguese" comes from, and for an origin spouse it is not true.

If your spouse became Portuguese by acquisition (naturalization)

Someone who acquired nationality became Portuguese only from the date it was registered, going forward, with no retroactive effect.

That changes the timing. During the years before they naturalized, you were not married to a Portuguese national, because they were not one yet. So the prevailing reading is that your three years count only from the point they became Portuguese, and a marriage that predates their naturalization does not count toward it.

This is the route your spouse holds if they became Portuguese through residence, through their own marriage, as a great-grandchild (which since 2026 is a naturalization route needing five years of residence, rather than a route of origin), or through the former Sephardic route. In each of these, the acquisition timing applies.

!: One caution: the law does not spell this timing rule out word for word, and it is a point where the registries and practitioners line up in practice but do not always agree on the edges. If your spouse naturalized after you married, confirm your own case with the IRN or the Conservatória dos Registos Centrais before you rely on it.

A quick way to tell which applies

Ask how your spouse got their nationality.

• Born to it (child or grandchild of a Portuguese citizen): origin. The whole marriage counts.
• Earned it later (residence, their own marriage, great-grandchild, Sephardic): acquisition. Count the three years from when they became Portuguese.

Is there a residency requirement?

No. The marriage route has no residency requirement and no minimum time in Portugal. Your eligibility rests on the three years with your spouse and the connection test, not on where you live.

This is exactly what makes it attractive next to the standard path.

Naturalization by residence now takes seven years of legal residence for EU and CPLP nationals and ten years for everyone else, and the clock only starts once your first residence permit is issued. Marriage skips all of it. If you qualify through both, marriage is almost always the faster one. (For the residence path, see our guide to Portuguese citizenship by naturalization.)

Can you apply without living in Portugal?

Yes. You can apply from your home country, with no physical presence and no residency to prove. You could marry a Portuguese national abroad, live together overseas for three years, and file from there.

There are two channels, and choosing well can save you months.

Applying from your home country

Two options, and they work the same whether you are in the UK, the US, or anywhere else.

Option 1: through your local Portuguese consulate

You book an appointment, present your file, and the consulate forwards it to Lisbon.

Consular declarations generally require you to sign in person. The upside is that a consular officer checks your file before it goes anywhere.

Option 2: mailing your file straight to Lisbon

You can send the complete, apostilled, translated file directly to the Conservatória dos Registos Centrais (CRC) in Lisbon by mail.

Your application form has to be signed with the signature recognized, either at a consulate or before a notary with a Hague Apostille. Sending straight to the CRC is an officially supported route, and some applicants report it moving faster than a busy consulate. Treat the speed part as an anecdote worth checking for your own consulate, because it varies.

One channel you cannot use yourself

The online submission through the IRN platform is reserved for lawyers and solicitors (mandatários).

If you hire one, they file online for you. If you do it yourself, you use the consulate or mail the CRC.

Applying from inside Portugal

If you live in Portugal, you can file in person at a Balcão da Nacionalidade (a nationality desk inside certain civil registry offices), at some Espaço Cidadão and Loja de Cidadão locations, or by mailing the CRC.

Living here is not required for the marriage route. But if you are already in Portugal, doing it in person lets a registrar catch problems on the spot.

What documents are needed for the application?

The core documents are your marriage certificate (registered in Portugal), your birth certificate, your spouse's Portuguese documents, criminal records, proof of your connection if you are not exempt, and the signed form. Everything foreign has to be apostilled and translated.

Here is the full list most applicants need.

Registering (transcribing) your marriage first

Before your citizenship application can move, the marriage has to be in the Portuguese system. This is a genuine step, and it comes with a choice most people do not expect.

What if you married abroad?

You complete the transcription of a marriage celebrated abroad, at the Portuguese consulate near where the wedding took place, or through the IRN in Portugal.

You will typically need your apostilled long-form foreign marriage certificate and your birth certificate. Expect roughly two to three months for the registration to come through, after which the citizenship step can begin.

The property regime you have to choose

When you transcribe a foreign marriage, Portugal asks which matrimonial property regime applies: full communion of property, communion of property acquired after marriage, or full separation of property.

This is not a formality. It affects how assets are treated under Portuguese law, so it is worth understanding (and, for larger estates, worth legal advice) before you register.

What if you are in a de facto union?

The equivalent first step is judicial recognition of the union by a Portuguese court, which then lets you apply. A union formed abroad usually has to be confirmed by a Portuguese court first.

Getting documents apostilled and translated

Portugal is part of the Hague Apostille Convention and does not accept foreign documents that are not properly apostilled.

As a rule, every foreign document that matters (your birth certificate, the foreign marriage certificate used for transcription, and your criminal records) needs a Hague Apostille from the issuing country, plus a certified translation into Portuguese if it is not already in Portuguese.

Small errors here are the single most common reason files get sent back: an expired record, a missing apostille, a certificate in the wrong format. Get these right once and you avoid the exigência loop entirely.

What is the process for obtaining citizenship, step by step?

The process runs in a clear order: register the marriage, gather and certify the documentation, sign and submit the form, then wait through the review stages. Here is the guide.

1. Register the marriage in Portugal. Transcribe your foreign marriage, or get judicial recognition of your union. Nothing else moves until this is done.
2. Gather and certify your documents. Order your birth certificate and criminal records, get them apostilled, and have anything not in Portuguese translated by a certified translator.
3. Complete and sign the form. Fill in the Portuguese-language nationality form and have your signature recognized at a consulate or notary.
4. Submit the file. Mail it to the Conservatória dos Registos Centrais in Lisbon, hand it in at your consulate, or (through a lawyer) file online.
5. Respond to any requests. If the Conservatória issues an exigência, you usually have a short window to fix it.
6. Receive the decision and register. Once approved and registered, you get your Portuguese birth record, then apply for a Cartão de Cidadão and a passport.

What are the stages once you submit?

Your application moves through four official statuses. You can follow it online with the process reference.

• Submetido (submitted): received and logged.
• Em análise (under review): requirements, completeness, and document authenticity are checked, including any external checks. This is where files spend the most time.
• Para decisão (for decision): a grant or refusal is being issued.
• Concluído (concluded): granted and registered, or refused and closed.

What happens if they request more documents?

The Conservatória issues an ‘exigência’, and you get a short window to respond, commonly around 20 to 30 days.

Missing that window is a frequent, avoidable cause of delay. A complete file at submission is the best way to never see one.

How long does it take to get citizenship?

Officially, there is no fixed statutory deadline. In practice, processing time for the marriage route currently runs into years, and the three years of marriage is only the starting line before you even submit.

Two separate clocks are worth keeping apart.

Registering the marriage abroad takes about two to three months. The citizenship application itself is the long part.

Recent guidance from established relocation sources puts current processing at around two to three years, sometimes longer, and notes it was closer to one year until recently, before the backlog grew.

Some Portuguese legal practices report marriage files taking more than four years to be reviewed. Read all of these as recent reports from people and firms working the queue, not as a promised timeline, because individual cases vary widely.

Why does it take so long?

The delays are structural rather than personal.

Portugal's registry system has absorbed a sharp rise in nationality requests, much of the process still runs on paper, and the "under review" stage can wait on responses from other bodies.

A new digital platform is meant to raise capacity, but it does not clear the paper backlog overnight. The 2026 legal change added a layer of administrative caution on top, as offices wait for the updated regulation.

Can you speed it up?

Not reliably, and be wary of anyone who promises otherwise.

What you can control is your own file. A complete, correctly certified application with nothing missing avoids the exigência loop, which is where a lot of the extra waiting comes from. Applications get approved faster when there is nothing to send back.

How much does Portuguese citizenship by marriage cost?

The government fee for citizenship by marriage is €250, paid to the IRN. On top of that, budget for the cost of getting your documents ready.

Fees are set by the Regulamento Emolumentar dos Registos e Notariado and can change, so confirm the current amounts with the IRN or your consulate before you pay.

One detail that reflects the legal difference between routes: the €250 applies to acquisition routes like marriage, while nationality of origin (for children and grandchildren of Portuguese citizens) carries a lower base fee.

Can children of married couples apply for citizenship?

It depends which children you mean, and this is where two different things get mixed up. Some children are already Portuguese and need nothing. Common children of the married couple actually help you, the applying spouse.

Three situations, kept separate.

Children of your Portuguese spouse

They are usually already Portuguese by descent, regardless of your marriage application.

If they were born to a Portuguese parent, that is a separate and usually simpler route. See our guide to Portuguese citizenship by descent.

Common children of the couple

If you and your spouse have children who are Portuguese, your evidence burden drops.

Common Portuguese children are one of the exemptions above: your connection to the Portuguese community is recognized automatically, so you generally do not have to prove ties separately. This is one of the most useful shortcuts in the whole route.

Your own children from before

They do not become Portuguese automatically when you acquire nationality by marriage, and here age is what decides it.

A minor child (under 18) can acquire nationality following you, by declaration, once your own acquisition goes through. This works even though marriage is an acquisition route, and it works whether or not the child is your Portuguese spouse's child.

An adult child (18 or over) cannot follow you this way. At that point they have to qualify on their own, through a route that fits them.

One caveat under the new law: older minors (from 16) may face the same integration and criminal-record conditions the 2026 law added elsewhere, so confirm the current requirements for a teenager's application. See Portuguese citizenship by naturalization for how acquisition by a minor works.

The clean takeaway: marriage makes you Portuguese. It does not sweep your whole family in by default. Map each child to the route that actually fits them.

Marriage vs the other routes to Portuguese citizenship

Marriage is one of several ways in, and it is worth a quick sanity check against the others, especially if you also have Portuguese ancestry or years of residence.

If you have a Portuguese parent or grandparent, the descent route is often cleaner than marriage and treats you as Portuguese from birth, which also helps your children.

If your only tie is that you live in Portugal, the residence route is now long, and marriage (if it applies) is faster.

And if you had a child in Portugal, that is a different question again. Each route has its own guide:

• Portuguese citizenship by descent (parents, grandparents, great-grandparents)
• Portuguese citizenship by naturalization (residence)
• Portuguese citizenship for children born in Portugal to foreign parents

So, is marriage your fastest route to a Portuguese passport?

For most people married to a Portuguese citizen, yes. Pulling the whole route together, here is what actually decides it.

The bar to qualify is low and stable. Three years married or in a recognized union, no requirement to live in Portugal, and your current passport stays. The May 2026 law left all of that intact.

The connection test is the real 2026 pinch-point. If you hit six years of marriage, have common Portuguese children, or are a national of a Portuguese-speaking country married five years, it is waived. If not, you build and document the ties yourself, and you start early rather than late.

The paperwork is where time gets lost, not the eligibility. A marriage that was not transcribed first, a criminal record in the wrong format, a missing apostille, a connection file assembled at the last minute. Get the file right once and you skip the 'exigência' loop that adds months.

The timeline is long and largely out of your hands. No fixed deadline, and recent reports put the wait in the range of two to four years. There is no reliable shortcut, only a clean file.
