Marriage in Portugal: What You Need to Know
Portugal recognizes both civil and religious marriages, and both have full legal force. For foreigners living in Portugal — whether as residents, digital nomads, or those planning to relocate — understanding the marriage process is essential, as it affects immigration status, property rights, tax obligations, and potentially the path to citizenship.
The process involves several stages: gathering and legalizing documents, opening the preliminary marriage process, the registry review and authorisation decision, and the ceremony itself. For couples where one or both partners are foreign nationals, additional steps are required to verify documents from abroad.
Types of Marriage in Portugal
Portuguese law recognizes two forms of marriage, both with identical legal effects:
| Type | Where | Legal Effect | Notes |
|---|---|---|---|
| Civil Marriage (Casamento Civil) | Conservatória do Registo Civil | Full legal recognition | The standard option; available to all couples |
| Religious Marriage (Casamento Católico/Religioso) | Church or place of worship | Full legal recognition | Must be registered civilly; Catholic marriages are automatically registered under the Concordat |
| Civil Union (União de Facto) | Not a ceremony | Legal recognition after 2 years | Available to all couples, including same-sex; provides many but not all marriage rights |
Same-Sex Marriage
Portugal legalized same-sex marriage in 2010. Same-sex couples have the same rights and follow the same process as opposite-sex couples for civil marriage.
Required Documents
The documents required depend on the nationality and civil status of each partner. Here is the comprehensive list:
Document Validity
There is no single universal validity period. The certificate of matrimonial capacity should be issued less than six months before use, unless its issuing authority sets another period. The birth certificate must satisfy the issuing-country and Portuguese registry requirements. Plan document gathering so everything is current at submission.
Certificate of Legal Capacity
This is often the most problematic document for foreigners. Not all countries issue this certificate in the same format. Some countries issue a 'Certificate of No Impediment' or 'Nulla Osta' instead. Check with your country's consulate in Portugal for the exact document your country provides.
For Portuguese Citizens
- Valid ID card (Cartão de Cidadão) or passport
- Birth certificate (obtained automatically by the Conservatória from the civil registry)
- Certificate of legal capacity to marry (if previously married: divorce decree or death certificate of former spouse)
For Foreign Nationals
- Valid passport
- Recent birth certificate that satisfies the issuing-country and Portuguese registry requirements
- Certificate of matrimonial capacity (Certificado de Capacidade Matrimonial) — issued by the authorities of your country of nationality, or an accepted substitute route where your country does not issue one
- If divorced: final divorce record; if widowed: death certificate of the former spouse
- Prenuptial-agreement documents when a different property arrangement is chosen
- Special power of attorney when one person is represented
Step-by-Step Marriage Process
Gather and Legalize Documents
2–8 weeksCollect all required documents. Legalisation depends on origin: covered EU public documents follow Regulation (EU) 2016/1191 and need no apostille; documents from Hague Apostille countries use an apostille; others use consular legalisation. Certified Portuguese translation is the general rule (English, French or Spanish documents avoid translation only when the competent registry officer handles that language, or an EU multilingual standard form covers them). This is typically the longest phase.
File the Marriage Application (Processo Preliminar de Casamento)
1 dayBoth partners visit the Conservatória do Registo Civil together to file the marriage application. Submit all documents and pay the initial fee. The registrar will review the documents and may request additional information.
Registry Review of the File
VariesThe Conservatória reviews the file and confirms that no legal impediment prevents the marriage. There is no fixed mandatory 30-day publication period.
Authorisation Decision (Despacho)
1–5 days after publicationThe preliminary process ends with the registry decision authorising or refusing the marriage. The certificate of matrimonial capacity is a foreign input document issued by the foreign partner’s own national authorities — not a Portuguese certificate issued after a publication period.
The Ceremony
30 minutes to 1 hourThe civil ceremony takes place at the Conservatória (or another approved location). Both partners must be present. Witnesses are optional — the couple can invite between two and four (of full age). The registrar reads the legal text, both partners declare their consent, and the marriage is registered immediately.
Choosing a Venue
While the standard venue is the Conservatória, you can request to hold the civil ceremony at another location (a hotel, garden, or historical venue). This requires advance arrangement and may involve additional fees. The registrar must be present at the chosen location.
Special Considerations for Foreigners
Foreign nationals marrying in Portugal face additional requirements and potential complications:
Language Barrier
The ceremony is conducted in Portuguese. If either partner does not speak Portuguese, an official interpreter must be present. The interpreter must be a certified translator or someone approved by the Conservatória. This should be arranged in advance.
Consular Involvement
Some countries require their citizens to notify the consulate before marrying abroad. Failure to do so may create problems when registering the marriage in your home country. Check with your consulate about any requirements before starting the process.
Prenuptial Agreements
International couples must confirm which country’s law governs their matrimonial property before the marriage file is finalised. The answer can depend on habitual residence, nationality, the couple’s closest connection and a valid choice of law. When Portuguese law applies and no different regime is chosen, the standard Portuguese regime is generally community of acquired assets (comunhão de adquiridos). To choose a different arrangement, sign a prenuptial agreement (convenção antenupcial) before the marriage.
Important for Property Owners
Confirm the applicable property regime before the marriage file is finalised. If either partner owns property or has significant assets, a prenuptial agreement lets you set the regime deliberately rather than leaving it to the applicable default.

Get a legal assessmentRegistering a Foreign Marriage in Portugal
Getting married in Portugal and transcribing a marriage celebrated abroad are different services. A Portuguese citizen who marries abroad normally transcribes that marriage into the Portuguese civil registry. Two foreign spouses do not automatically need Portuguese transcription — they normally prepare the foreign marriage certificate for the specific Portuguese procedure that requires it. Transcription can matter for:
- A Portuguese citizen entering a foreign marriage in the Portuguese civil registry
- Using the marriage in a Portuguese procedure that requires the registered record
- Certain nationality, residence or family procedures that ask for it
Obtain Your Marriage Certificate
Get an official marriage certificate from the country where the marriage took place. It must be a recent issue (within the last 6 months for most purposes).
Apostille and Translate
Legalise the marriage certificate (apostille, EU route or consular legalisation as applicable), then obtain a certified Portuguese translation where the receiving procedure requires it.
Submit to Conservatória
File the registration request at any Conservatória do Registo Civil in Portugal. Submit the legalised and (where required) translated marriage certificate along with identification documents for both spouses.
Receive Portuguese Marriage Registration
After processing (typically 2–4 weeks), the marriage will be registered in the Portuguese civil registry. You can then obtain a Portuguese marriage certificate (certidão de casamento).
Costs and Timeline
The base state fee for the civil-marriage process is €120. The overall cost depends on the foreign-document route (legalisation, certified translation), any prenuptial agreement, interpreter or power of attorney, and specialist legal work — quoted separately per case.

|---|---|---|
| Base civil-marriage registry process | €120 | Weekday, at the Conservatória, in working hours |
| Off-site, weekend or out-of-hours ceremony | Additional official charge | Set by the registry |

| Registry review and authorisation decision | Varies |
| Window to celebrate after authorisation | Up to 6 months |

After the Wedding: Legal Steps
After your marriage ceremony, several administrative steps may be necessary:
- Update your tax status at Finanças — married couples can file jointly, which may reduce taxes
- Update your residence permit if your name has changed or if the marriage affects your immigration status
- Notify your country's consulate about the marriage for registration in your home country
- Update bank accounts, insurance, and other financial documents
- If applicable, begin the process for citizenship by marriage (eligible after 3 years if living in Portugal, 6 years if abroad)
- Consider updating your will or creating one — marriage changes inheritance rules in Portugal
Path to Citizenship
Marriage to a Portuguese citizen opens a pathway to citizenship. If living in Portugal, you can apply after 3 years of marriage. If living abroad, after 6 years. The application requires proof of effective connection to the Portuguese community — language skills, social integration, and ties to Portugal.
