Marrying in Portugal as a Foreigner: The Conservatória Process, Documents, Costs, and União de Facto Explained for 2026

Who This Guide Is For

Portugal does not require either partner to be a Portuguese resident, a Portuguese citizen, or even to have ever set foot in the country before to get legally married on Portuguese soil. Couples fly in from the United States, Brazil, the UK, and across the EU every week to marry at a Conservatória do Registo Civil or at a venue in the Algarve, Lisbon, or the Douro. Foreign residents already living in Portugal use the same process, just with fewer apostilled documents to send back and forth.

This guide covers the civil legal pathway, Catholic-church marriage, the cost of each, and the união de facto alternative for couples who want the legal protections of a shared life but not the wedding.

Types of Marriage Recognised in Portugal

Civil marriage (casamento civil) — the default. Performed by a registrar either inside the Conservatória or at a venue of the couple's choice. All civil marriages — straight or same-sex — have identical legal effect. Same-sex marriage has been fully legal in Portugal since 2010, and same-sex couples have had equal adoption rights since 2016.

Catholic marriage (casamento católico) — recognised as legally binding under the 1940 Concordata with the Holy See. A Catholic wedding held in a Portuguese parish is automatically registered as a civil marriage. Both partners must be Catholic and neither can be divorced (a civil divorce does not unlock a Catholic wedding; annulment does).

Other religious ceremonies — weddings in a mosque, synagogue, Protestant church, Hindu temple, or under a humanist or pagan celebrant are not legally recognised. Couples wanting one of these ceremonies have to hold a separate civil marriage at the Conservatória either before or after.

Symbolic weddings — popular on Algarve cliffs and Douro quintas. These carry zero legal weight in Portugal. The couple must already be legally married, or have a civil ceremony scheduled separately.

Who Can Marry in Portugal

• Minimum age: 18. Sixteen- and seventeen-year-olds can apply with parental or guardian consent and Conservatória authorisation.
• Marital status: Both parties must be free to marry. A previous marriage must be ended by divorce, annulment, or death, and proof must be produced.
• Capacity: Neither party may be under court-ordered accompanied-person restrictions on marriage, or suffering from medically certified dementia.
• Relationship: Marriage is barred between direct ascendants and descendants, full or half siblings, adoptive parents and adopted children, and between a person and anyone convicted of killing that person's former spouse.

There is no residency, visa, or nationality requirement. Tourists on a Schengen 90-day stamp can marry on the same terms as residents.

The Conservatória Process (Processo Preliminar)

Every legal marriage in Portugal — civil or Catholic — starts with a processo preliminar de casamento: a preliminary publication of intent at the Conservatória do Registo Civil in the council (concelho) where either partner lives, or where the marriage will take place.

Couples who are already in Portugal can open the process online through the Instituto dos Registos e Notariado portal at registosonline.registos.justica.gov.pt. Those abroad typically present documents in person on arrival or through a lawyer with power of attorney. Expect the full application, publication of banns, and authorisation to take four to six weeks — so budget at least six before setting a wedding date.

The Conservatória publishes the intent on its public platform for eight days. If no impediment is raised during that window, it issues the certidão de capacidade matrimonial: the authorisation to marry.

Documents You Need

Core list for both partners:

• Birth certificate — certified copy, issued within the last six months.
• Passport or Cartão de Cidadão / residence permit — for identification.
• Certificate of No Impediment (certidão de capacidade matrimonial) — proof you are legally free to marry, issued by the competent authority in your country. In the US this is a court affidavit of no impediment; in the UK it is the Certificate of No Impediment from your local register office. EU citizens can usually get it from their consulate in Lisbon.
• Final divorce decree or death certificate of any previous spouse.
• Parental consent — if either partner is 16 or 17.
• NIF (Portuguese tax number) — requested for foreign residents but not a legal blocker for non-residents.

Apostille and Translation Rules

Documents issued outside Portugal must be legalised with a Hague Apostille from the issuing country, unless a bilateral agreement waives it (rare — Brazil-Portugal notably does, between certain document types).

Translation rules are more generous than most EU countries:

• Documents in Portuguese, English, Spanish, or French are generally accepted without translation at most Conservatórias — although local practice varies and the registrar has final say.
• Documents in any other language need a certified translation (tradução certificada) performed in Portugal by a lawyer, notary, or certified translator, or legalised at a Portuguese consulate abroad.

Every foreign document presented must be valid and dated within six months of submission. An apostille applied after the document's issue date does not reset that clock.

How Much It Costs

Official Conservatória fees for the standard processo preliminar and civil ceremony:

• Standard weekday civil marriage (Monday to Friday, normal hours, at the Conservatória): EUR 120
• Weekend, public holiday, or out-of-hours ceremony: EUR 200
• Off-site ceremony (at a hotel, quinta, restaurant, beach, or other venue): adds a supplement of roughly EUR 130-180 depending on the concelho
• Urgent process (processo urgente): can be requested for an additional fee, typically doubling the standard price

These fees cover the legal registration only. Translations, apostilles, certified document copies, a lawyer's fee for power of attorney, and any wedding-planner, venue, celebrant, or decoration costs are entirely separate. A destination wedding budget in the Algarve typically runs from EUR 5,000 for a very small ceremony to EUR 25,000-60,000 for a full weekend event.

Property Regimes — Choose Before You Marry

Portugal requires you to pick a property regime (regime de bens) as part of the application. The choice affects what happens to assets during the marriage and on divorce or death.

• Comunhão de adquiridos — the default if you pick nothing. Assets owned before the marriage stay personal; anything acquired during the marriage is shared.
• Separação de bens — each spouse keeps sole ownership of all assets, before and after. Required by law if either partner is over 60 or has children from a previous relationship at the time of marriage.
• Comunhão geral — all assets, including those owned before the marriage, become joint. Rare, and not available where separação de bens is mandatory.

A prenuptial agreement (convenção antenupcial) is signed at a Notary before the wedding if you want to deviate from the default regime.

The Ceremony Itself

• Witnesses: two required, one for each spouse. They must be at least 18 and can be any nationality. A passport, Cartão de Cidadão, or residence permit is enough.
• Duration: the legal part takes about 15-20 minutes. The registrar reads the legal text, takes the consent of each spouse, records the property regime, and registers the marriage on the spot.
• Language: the ceremony is in Portuguese. If either spouse does not understand Portuguese, the Conservatória will require a certified interpreter — this can be arranged privately or through a translation agency.
• Certificate: a certidão de casamento is issued on the day and is the document you will use to register the marriage abroad.

Registering Your Marriage Back Home

A Portuguese marriage is legally valid in every country that recognises civil marriage, but most will require you to register it domestically through the consulate. You will usually need:

• The original certidão de casamento, legalised with a Portuguese Apostille from the Procuradoria-Geral da República
• A certified translation into the country's official language where required
• The consular registration form for your home country

UK citizens can register at the British Consulate in Portimão or Lisbon. US citizens usually register at the US Embassy. Brazilians can register through the Consulado-Geral in Lisbon, and the Brazilian CIN biometric ID (now issued in Lisbon since April 2026) reflects the new marital status automatically.

União de Facto — the Legal Alternative to Marriage

For couples who want the legal protections of shared life without the wedding, Portugal offers a formal união de facto (registered partnership) regime.

• Qualification: two years of uninterrupted cohabitation in a relationship comparable to marriage. It is available to same-sex and opposite-sex couples, and to foreign residents.
• Evidence: proved with a declaração from the local Junta de Freguesia confirming shared address for the full two years, plus affidavits from two witnesses. Joint utility bills, rental contracts, and bank statements strengthen the file.
• Rights granted: most social-security spousal benefits, inheritance tax exemption, priority in hospital access for partner decisions, residence authorisation for the non-EU partner, and the right to adopt jointly.
• What it does not give: automatic property sharing (you fall under separação de bens by default), the Portuguese citizenship shortcut that married spouses enjoy, or the right to take the partner's surname.

A união de facto is not automatically recognised abroad. If one partner moves back to a country that does not recognise civil partnerships, the legal shield goes with them only to the extent the foreign jurisdiction mirrors it.

Common Pitfalls

• Expired documents. Birth certificates and certificates of no impediment must be dated within the last six months. An apostille stamped months later does not refresh the underlying document.
• Missing apostille. Foreign documents without a Hague Apostille from the issuing country will be rejected. Plan for two to six weeks of mail turnaround, depending on country.
• Wrong regime. Comunhão geral is legally impossible where either party is over 60 or has prior children. The Conservatória will block it at the banns stage — but couples who assumed they had it sometimes only discover the default when drafting wills.
• Symbolic ceremonies. A ceremony with a celebrant on a Sintra hilltop is beautiful and legally worthless. Schedule the civil registration separately.

Key Contacts

• Instituto dos Registos e Notariado (IRN) — national body for civil registration. Online portal at registosonline.registos.justica.gov.pt. Telephone 211 950 500.
• Conservatórias do Registo Civil — located in every concelho. The one in Lisbon (Conservatória do Registo Civil de Lisboa, Rua Alexandre Herculano 112) handles international-couple weddings most weeks.
• Procuradoria-Geral da República — applies Portuguese apostilles to Portuguese documents for use abroad.
• Ordem dos Notários — for finding a notary to draw up a prenuptial agreement or power of attorney.

Last updated: April 2026. Fees and procedures are set by national law but fine detail can vary between Conservatórias. Always check with the specific office you plan to marry in before booking flights.
