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, filing a marriage application, a mandatory publication period, 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
Most foreign documents must be issued within the last 6 months. Criminal records and certificates of legal capacity may have shorter validity periods (3 months). Plan your document gathering carefully to ensure everything is current at the time of 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
- Birth certificate — apostilled and translated into Portuguese by a certified translator
- Certificate of legal capacity to marry (Certificado de Capacidade Matrimonial) — issued by the authorities of your country of nationality, apostilled and translated
- Certificate of civil status (single, divorced, or widowed) — apostilled and translated
- If divorced: final divorce decree — apostilled and translated
- If widowed: death certificate of former spouse — apostilled and translated
- Proof of legal residence in Portugal (residence permit or visa)
- NIF (Portuguese tax number)
Step-by-Step Marriage Process
Gather and Legalize Documents
2–8 weeksCollect all required documents. Foreign documents must be apostilled in the country of origin, then translated into Portuguese by a certified translator in Portugal, and the translation must be notarized. This is typically the longest phase of the process.
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.
Publication Period (Publicação de Editais)
30 daysThe marriage intention is publicly announced for 30 days. This is a legal requirement to allow any objections to be raised. The announcement is posted at the Conservatória and, for foreign nationals, may also be communicated to their country's consulate.
Certificate of No Impediment
1–5 days after publicationIf no objections are raised during the publication period, the Conservatória issues a Certificate of No Impediment (Certificado de Não Impedimento). This certificate is valid for 3 months — the ceremony must take place within this period.
The Ceremony
30 minutes to 1 hourThe civil ceremony takes place at the Conservatória (or another approved location). Both partners must be present with two witnesses (aged 18 or older). 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
Portugal's default matrimonial property regime is 'communion of acquired assets' (comunhão de adquiridos) — assets acquired during the marriage are shared equally. If you want a different arrangement, you must sign a prenuptial agreement (convenção antenupcial) before the marriage. This requires a separate notarial process.
Important for Property Owners
If either partner owns property or has significant assets, consider a prenuptial agreement. Without one, the default regime applies automatically. Changing the property regime after marriage is possible but complex and expensive.
Registering a Foreign Marriage in Portugal
If you married abroad and now live in Portugal, you may need to register your marriage with the Portuguese civil registry. This is necessary for:
- Using your married name on Portuguese documents
- Tax filing as a married couple
- Applying for citizenship through marriage
- Inheritance and property rights in Portugal
- Family reunification visa applications
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
Have the marriage certificate apostilled in the country of issue, then translated into Portuguese by a certified translator in Portugal, and the translation notarized.
Submit to Conservatória
File the registration request at any Conservatória do Registo Civil in Portugal. Submit the apostilled and 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 total cost for a civil marriage in Portugal, including document legalization for one foreign partner, typically ranges from €500 to €1,500. For couples where both partners are foreign nationals with documents from different countries, costs may be higher due to additional translations and legalizations.
| Item | Cost | Notes |
|---|---|---|
| Marriage application fee | €200–300 | Varies by Conservatória |
| Ceremony at Conservatória | Included in application fee | Standard venue |
| Ceremony at external venue | €100–300 additional | Plus venue rental costs |

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.
