TL;DR: Expats can legally marry in Portugal at a Conservatória do Registo Civil (civil registry office). The process requires gathering specific documents from your home country (birth certificate, proof of single status, criminal record — all apostilled), submitting them to the registry office, waiting for publication of banns (typically 30 days), and attending the ceremony. The ceremony itself is in Portuguese. Marriages conducted in Portugal are legally recognised in most countries. Budget 2–4 months for the full process. English-language support from a local lawyer or wedding coordinator makes the administrative side significantly smoother.
More expat couples in Portugal marry here than most people expect — either because they moved here as a couple and want to marry in their adopted home, or because they want to marry in Portugal specifically for the setting. Whatever the reason, the process is manageable, the outcomes are legally solid, and the bureaucratic journey — while real — is not as daunting as it first appears.
Civil vs Religious Ceremonies
This guide focuses on civil ceremonies — the route used by most expat couples. Religious ceremonies (Catholic, Church of England, and some others) are also legally recognised in Portugal and have their own requirements. For a Catholic ceremony, the Church administers much of the process. For other religious ceremonies, contact your specific religious institution in Portugal for guidance.
A civil ceremony at the Conservatória do Registo Civil is a fully legal marriage in Portugal and is recognised internationally without requiring any additional steps.
Documents Required
Both parties need to provide the following. All foreign documents must be apostilled and, if not in Portuguese, officially translated by a certified translator (tradutor juramentado).
- Birth certificate — apostilled copy from your home country. UK birth certificates are apostilled by the FCDO; US birth certificates by the relevant state Secretary of State.
- Proof of civil status (single status / freedom to marry) — also called a Certificate of No Impediment (CNI) or Certificate of Civil Status. In the UK, obtained from the General Register Office or local register office. In the US, varies by state — often a sworn affidavit. In some countries this document is called a Certificado de Capacidade Matrimonial. This is the document that most often causes delays — processing can take 4–8 weeks in some countries.
- Valid passport (original)
- NIF (Portuguese tax number)
- Proof of address in Portugal (rental contract)
- Criminal record certificate (apostilled) — required by some registries, not all. Check with your specific Conservatória.
- Divorce certificate if previously married — apostilled and translated.
- Death certificate of previous spouse if widowed — apostilled and translated.
The Process Step by Step
Step 1: Choose your registry office
Marriages are conducted at the Conservatória do Registo Civil covering the address where at least one partner is resident. In Porto, the main office is on Rua de Camões. You can also choose to marry in a different location (a quinta, garden, or other venue) — some registry offices offer off-site ceremonies for an additional fee. Confirm this option directly with your registry office.
Step 2: Gather and apostille your documents
Start this step 3–4 months before your intended wedding date. The Certificate of No Impediment / Freedom to Marry is the most time-sensitive document — in the UK it requires a 28-day waiting period after application before it can be issued. Apply early.
Once you have all documents apostilled, engage a certified translator (tradutor juramentado) in Portugal for any documents not in Portuguese. The Conservatória may have a list of approved translators or you can find certified translators through the Ordem dos Tradutores e Intérpretes.
Step 3: Submit your application to the Conservatória
Book an appointment at the Conservatória do Registo Civil and attend together (both parties must be present for the initial submission). Submit all documents. The registry officer will review them and either accept the application or request additional documents.
Step 4: Publication of banns
Once your documents are accepted, the Conservatória publishes banns (publicação de proclamas) — a public notice that you intend to marry. This period lasts approximately 30 days, during which any legal impediment to the marriage can be raised. After the 30 days, you are cleared to schedule the ceremony.
Step 5: Book and attend the ceremony
The civil ceremony at the Conservatória itself is brief — typically 20–30 minutes. It is conducted in Portuguese by the registry officer (conservador). The officiant reads the legal declaration of marriage; you and your witnesses respond. Two witnesses are required (Portuguese nationals or legal residents with ID). You sign the marriage register and receive a marriage certificate.
If you want an off-site ceremony (at a quinta, garden, or other venue), this is arranged with the registry office and typically costs an additional €150–€500 depending on the distance and day. Weekend ceremonies may also carry a surcharge.
The Ceremony Is in Portuguese — What to Know
The legal ceremony is conducted in Portuguese — this is a legal requirement, not a preference. The officiant reads the legal text of the marriage declaration in Portuguese, and you respond. If neither partner speaks Portuguese, the registry may require a certified interpreter to be present. Some registry offices have English-speaking staff who can guide you through the ceremony informally, but the official ceremony is legally required to be in Portuguese.
Many couples choose to have a bilingual celebration — the legal civil ceremony in Portuguese at the registry office, followed by a separate celebrant-led ceremony in English (or both languages) at their reception venue. The celebrant ceremony is not the legal ceremony but allows for personalised vows, readings, and the emotional experience of a ceremony in your own language.
Is Your Portuguese Marriage Recognised at Home?
A civil marriage conducted in Portugal is legally recognised in the UK, Ireland, US, Australia, Canada, and most countries that recognise Portuguese civil law marriages — which is almost all of them. You typically need to register the marriage in your home country or at your home country’s embassy in Portugal. In the UK, you do not need to register a foreign marriage — your Portuguese marriage certificate (apostilled) is sufficient evidence. Check your specific country’s requirements.

Using a Lawyer or Wedding Coordinator
Not strictly necessary, but strongly recommended for the document gathering phase — particularly for getting the Certificate of No Impediment right and ensuring translations are certified correctly. A Portuguese lawyer with experience in family law or a specialist expat wedding coordinator can manage the entire administrative process, leaving you to focus on the celebration. Cost: €300–€800 for the administrative support, separate from any wedding planning services.
