Getting Married in Portugal as a Foreigner in 2026 — Civil Ceremonies, the Conservatória do Registo Civil, the Certificado de Capacidade Matrimonial, Same-Sex Marriage, and the Property Regimes That Decide Who Owns What

Marrying in Portugal is, for most foreign couples, less complicated and less expensive than the same procedure back home. The civil ceremony has been the dominant form since 1910, the State recognises three modalities (civil, Catholic religious, and civil-form religious), same-sex marriage has been fully legal since 2010, and the entire process can be initiated at any conservatória do registo civil in the country — or online through the Civil Online portal — for a base fee of €120. The catch, as ever, is the paperwork: foreign nationals need authenticated documents, certified translations, an apostille for non-EU origin certificates, and either a certificate of matrimonial capacity from their home country or a Portuguese-issued declaration acknowledging that none is available. This guide walks through the full 2026 process, the costs, the timing, the property regimes, and the post-marriage steps that matter for residency, naturalisation, and tax.

The three forms of marriage Portugal recognises

Portuguese law recognises three modalities of marriage, all with full civil legal effect:

Casamento civil — celebrated by a registry official at any conservatória do registo civil. The most common option, used by the majority of Portuguese and almost all foreigners marrying in Portugal.
Casamento católico — celebrated by a Catholic priest under the Concordata between Portugal and the Holy See. Carries automatic civil effect once registered with the conservatória.
Casamento civil em forma religiosa — celebrated by an officiant of a non-Catholic religion that has signed a recognition agreement with the State. The civil registry official is not present; the religious officiant performs the legally binding civil ceremony.

Same-sex marriage was legalised by Lei n.º 9/2010 and applies to all three modalities. Foreign same-sex couples can marry in Portugal on the same terms as opposite-sex couples and on the same terms as Portuguese citizens.

Where to start the process

The marriage process — the processo preliminar de casamento — can be initiated at any conservatória do registo civil in Portugal, regardless of where the couple actually plans to hold the ceremony. Both members of the couple, or representatives with special powers of attorney, present themselves at the registry, declare their intention to marry, and provide the required documents. The Civil Online portal at civilonline.mj.pt allows the same declaration to be filed digitally if both parties already hold valid Portuguese identification (Cartão de Cidadão or NIF with Chave Móvel Digital) — which excludes most foreign newcomers from this route at the start.

The registry will check that no impediments exist (under-18 without parental consent, existing marriage, prohibited family relationship, certain criminal convictions), open the formal process, and — if both parties are foreign or one is — request the additional foreigner-specific documents. The marriage authorisation is then valid for six months from issuance; the ceremony must take place inside that window.

Documents required for foreign nationals

The following list applies to a foreign national marrying in Portugal. The exact requirements vary slightly by nationality, residency status, and which country issues the home-country documents, but the core set is consistent.

Valid passport or Portuguese residence authorisation. A photocopy is taken at the conservatória; the original is shown.
Birth certificate from the country of origin. Issued in international model where possible. If issued in any language other than Portuguese, English, French or Spanish, a certified Portuguese translation is required. If the issuing country is outside the EU, the certificate must be apostilled under the Hague Convention or, where the country is not a Hague signatory, legalised through the relevant Portuguese consulate.
Certificado de Capacidade Matrimonial (Certificate of Matrimonial Capacity). Issued by the competent authority of the foreign national's home country, less than six months old, attesting that the person is legally free to marry. Some countries — notably the United States, Canada, the United Kingdom, Australia and several others — do not issue this certificate. In those cases, the foreign national must present a sworn declaration (often via the home-country consulate or a notary) that no impediment exists, and the conservatória issues a Portuguese-side acknowledgement.
NIF (Número de Identificação Fiscal), if the foreign national is or will become resident.
Marriage capacity declaration from the consulate in cases where the country does not issue the certificate above.

Documents not in Portuguese, English, French or Spanish must be translated by a certified translator. Apostilles are required on every non-EU document of civil-status origin unless a bilateral exemption applies.

The fees: what marriage actually costs at the registry

The 2026 fee schedule under the Regulamento Emolumentar dos Registos e do Notariado is straightforward:

Standard civil-registry marriage: €120.
Non-urgent ceremony outside the registry premises (a hotel, a beach venue, a private estate): €200.
Non-urgent ceremony outside normal hours, on weekends or holidays: €200.
Standard prenuptial property-regime agreement: €100.
Non-standard prenuptial agreement: €160.
Registry of an external prenuptial agreement (e.g. a notarial deed): €30.

The base €120 covers the matrimonial capacity check, the formal authorisation, the ceremony at the registry, and the recording of the marriage in the civil register. Foreign couples who want to marry on a Saturday, in the Algarve, in a hotel garden — the most common request — will pay €120 + €200 + travel expenses agreed with the registry official.

Timing: how long the process takes

The minimum lead time the State requires is one month — the registry needs that window to verify documents and check for impediments. In practice, foreign couples should plan for two to three months from first conservatória appointment to ceremony, allowing time for translations, apostilles, and consulate-issued documents to arrive. Once the marriage authorisation is issued, it is valid for six months. If the ceremony does not take place inside that window, the process must be re-opened.

Booking the ceremony date itself depends on the conservatória's calendar. Lisbon's central registries and the Algarve coastal registries (Loulé, Albufeira, Lagos) are heavily booked in summer; couples planning a June-September ceremony should approach the registry by January or February at the latest.

The property regime: the choice that decides who owns what

Portuguese marriage law sets a default property regime — comunhão de adquiridos — that applies automatically unless the couple chooses an alternative in a prenuptial agreement (convenção antenupcial). The four main regimes:

Comunhão de adquiridos (default). Each spouse keeps as personal property anything owned before the marriage and anything received as gift or inheritance during the marriage. Property and income acquired jointly during the marriage become common property.
Comunhão geral de bens. Almost everything — pre-marriage assets, post-marriage assets, with limited exceptions — becomes common. Now relatively rare and not available where one spouse has children from a previous relationship or is over 60.
Separação de bens. Each spouse retains full ownership of their own property; nothing becomes common automatically. Required by law where one spouse is over 60 at the time of marriage. Often chosen by couples with significant pre-marriage wealth or from common-law jurisdictions where this regime is closest to default expectations.
Custom regime negotiated within the limits set by the Civil Code. Drafted in a notarial prenuptial deed.

Foreign couples often choose separação de bens because it most closely resembles the "separate property" default of US, UK, Irish and Australian common-law marriage. The choice must be filed before the ceremony in a prenuptial agreement; it cannot be retroactively imposed.

Witnesses, ceremony format, and language

Portuguese law allows between two and four witnesses, but witnesses are not strictly mandatory; the ceremony can proceed with the registry official and the couple alone. Most couples bring two. Witnesses must be over 18, present photo ID, and sign the marriage record.

The ceremony is conducted in Portuguese. If either spouse does not speak Portuguese, the registry will appoint a sworn interpreter — couples can also bring a private interpreter if approved in advance. The text of the ceremony is short and prescribed: a recital of identity, a statement of free consent, exchange of sim, and signature of the marriage record.

After the marriage: what changes

The marriage is automatically registered in the Portuguese civil register on the day of the ceremony. A Certidão de Casamento can be requested immediately, in person or online via the Civil Online portal, for €10 in plain copy or €20 with apostille for use abroad.

Three downstream effects matter for foreigners:

Residency. Marriage to a Portuguese citizen or to a legally resident foreigner is a recognised basis for a family-reunification residence permit through AIMA. The non-Portuguese spouse can apply for an autorização de residência on family grounds, typically with a faster track than economic-migration routes.
Naturalisation. Under Portuguese nationality law, a foreign spouse of a Portuguese citizen can apply for citizenship by marriage after three years of marriage, regardless of residence. This route is being modified in 2026 by Parliament's revision of the nationality law — couples should verify the residency component, the Portuguese-language requirement, and any "effective ties" test that may apply when the new framework takes effect.
Tax and inheritance. Married couples may file IRS jointly or separately. Inheritance between spouses is exempt from Imposto do Selo. The chosen property regime governs how assets are divided in the event of divorce or death — couples relocating to Portugal with pre-marriage wealth should review their regime choice with a Portuguese lawyer before signing, since the regime cannot easily be changed after marriage.

What to bring to your first conservatória appointment

For a foreign-foreign or foreign-Portuguese couple, the practical checklist for the first appointment looks like this:

Both passports (or Portuguese residence cards), original plus photocopy.
Both birth certificates, apostilled where required, with certified Portuguese translation if not in PT/EN/FR/ES.
Certificate of matrimonial capacity (or consular declaration in lieu) for each foreign national, less than six months old.
NIFs for both spouses, if either is or will become Portuguese-resident.
Decision on property regime (or a draft prenuptial agreement if a non-default regime is wanted).
Two witnesses identified by name and ID number for the ceremony date.
The €120 base fee, plus any supplementary fees for off-premises or out-of-hours ceremonies.

Marrying in Portugal is built around documents, not theatre. The State asks for proof that both parties are free to marry, that the marriage is consensual, and that the property arrangement has been declared. With those boxes ticked — and with the apostilles and translations done in advance — most couples are signing the marriage record inside a single 30-minute ceremony, and walking out as spouses under Portuguese, EU and home-country law on the same day.
