If you can’t book a marriage registry office in Portugal, you may still be able to start your marriage process in person: registry offices provide attendance with or without an appointment. You can also start the process at any Civil Registry Office (Conservatória do Registo Civil), although the ceremony date and place must be agreed with the registrar. Here’s how to choose your next step.

Can you attend without an appointment?

In-person attendance at registry offices is available both with and without an appointment. That means a missing online booking does not automatically prevent you from asking to start the marriage process at a counter. You can use the Siga appointment platform or its app to book, but an appointment is not the only way to attend in person.

Attending without a booking and having a confirmed appointment are different arrangements. If you are planning a visit, check what you need to present and whether the office can deal with the step you want to take. The marriage process itself begins with a declaration of intent, and the registry office examines the file before authorising the marriage.

You can also make an appointment through the Siga platform or app. If you choose the online marriage process instead, the appointment is only marked once the registry office sends confirmation. Submitting an online request is therefore not, by itself, proof that a booking or ceremony date has been secured.

Important: Do not treat an online request as a confirmed appointment. Wait for confirmation from the registry office before making arrangements that depend on a booked appointment, and remember that the ceremony date is agreed separately with the registrar.

Can another registry office help?

The marriage process can be started at any Civil Registry Office, not only the office closest to your home or the place where you hope to marry. If one office has no appointment that suits you, you can consider asking another registry office to receive the initial declaration. This gives you another location to approach, while the file remains subject to the registry office’s examination.

Starting the file and choosing where the ceremony takes place are related, but they are not identical choices. When you make the declaration, you indicate the intended venue, and the ceremony’s date, time and place are agreed with the registrar. If you approach a different office, explain where you hope to marry and ask how it will handle the proposed arrangements.

Think about the whole journey before choosing an office. If you and your partner live in different areas, a more distant counter may mean additional travel for appointments or document checks. If your preferred ceremony venue is elsewhere, clarify the venue with the registry office before paying for travel, accommodation or other arrangements.

Where the administrative route is unclear, legal support can help you compare the available options, review the information in your file and prepare a clear request to the relevant office. My view is that changing offices should be based on practical needs, such as location or access, rather than an assumption about how the process will be handled.

Online or in person: which route fits?

The online route may be available when both people meet the stated eligibility conditions: they must be over 18, be Portuguese citizens or Brazilian citizens with general equality of rights and duties, and have a Citizen Card. One partner starts the request and enters the couple’s and ceremony details; the other partner then authenticates and confirms it.

Both partners need to complete their part of the online request. After the second partner confirms, the request is sent to the selected registry office, and the couple is informed about the process. The appointment is only marked after the office confirms it, so do not treat the online submission as a confirmed booking or as authorisation to marry.

If you do not meet the online conditions, or if you need to present a prenuptial agreement, the in-person route may be more suitable. Prenuptial agreements cannot be completed online; they must be handled at a registry office or notary’s office. A paper process also allows you to present the documents required for a foreign partner’s file.

Choose the route based on what you need to submit, not only on convenience. If one partner is foreign, check the identification, birth certificate and matrimonial-capacity documents before attending. A lawyer can review whether the route you intend to use fits the couple’s circumstances and help prepare the application documents.

What happens when you start the process?

The process begins with a declaration that you intend to marry. You must indicate whether the ceremony will be civil, Catholic or civil in religious form, the intended place and the matrimonial property regime. These choices matter because they define what the registry office reviews and help shape the arrangements for the ceremony.

The couple can submit the declaration themselves, or use a representative with special powers. A parish priest or minister of a religious community established in Portugal can also initiate the process by submitting a signed request. Whichever route you choose, the registry office examines whether there are impediments before authorising the marriage.

If the registry office authorises the marriage, the ceremony must take place within six months of that authorisation. If it does not authorise the marriage, the couple is notified personally or by registered letter. Anyone who knows of an impediment may report it to the registry office before the wedding, so the file is examined before the ceremony is authorised.

For a ceremony on a particular date, start the process at least one month beforehand. This is the minimum lead time for starting the file, not a promise that the office will authorise it by a particular day. Leave room in your plans for the registry office to examine the documents and for you to provide anything else it requires.

Documents for a foreign partner

When one or both partners are foreign nationals, prepare the documents required to establish identity and eligibility to marry. The foreign partner must present a passport or residence permit, a birth certificate issued under the law of their country, and a certificate of matrimonial capacity if their country issues one. The certificate must be less than six months old.

If the partner’s country does not issue a certificate of matrimonial capacity, the required alternative is a declaration stating that the certificate is not issued. This distinction can affect how you prepare the file: requesting a document that does not exist may waste time, while arriving without the required declaration may leave the registry office without the information it needs to assess the application.

Foreign-language documents need attention before the appointment. Birth certificates and other documents that are not in English, French or Spanish must be accompanied by a certified translation into Portuguese. If the foreign partner does not understand Portuguese and the registry official does not speak the partner’s language, an interpreter is appointed for the marriage process.

Additional documents may be required if they are necessary to assess the file. For that reason, build a checklist around each partner’s nationality and personal circumstances, rather than assuming that one standard set of papers will fit every couple. My professional view is that document review before submission is especially useful when certificates must be obtained abroad or translated. If the registry office rejects your documents, read my guide on what to do when marriage documents are rejected in Portugal.

Dates, venues and marriage costs

The date, time and place of the civil ceremony are agreed with the registrar. You can marry at a registry office during its normal opening hours, or agree to a different venue or time in advance. A date that works for your venue or guests still needs to be agreed with the registrar, so a venue booking alone does not settle the civil ceremony arrangements.

The standard process and marriage registration cost €120. A non-urgent ceremony costs €200 if it takes place outside the registry office, outside normal opening hours, on a Saturday or Sunday, or on a public holiday. When the ceremony is held outside the office, the couple must also provide transport or pay the registrar’s travel costs.

A prenuptial agreement can add to the total. Making one that uses a regime provided for in the Civil Code costs an additional €100; making an agreement for a different, couple-defined regime costs €160. If the agreement or an amendment is registered after being made outside a registry office, the registration cost is €30.

The figures below separate the basic registration from common additional costs. They do not include the registrar’s travel costs for an off-site ceremony, because those depend on the arrangements. Confirm the planned venue, timing and property regime before making financial commitments based on the standard €120 fee.

If one partner cannot attend

One partner may be represented by a proxy, but this is not an informal arrangement. The registry office requires a power of attorney, which can be an authenticated document, a public instrument prepared by a notary or Portuguese consular official, or a document signed by the represented partner with their signature formally witnessed.

The power of attorney must identify the other partner by name, age, place of birth, habitual residence and parentage. It must also state the matrimonial property regime and the form of the ceremony. If any of these details is missing or inconsistent with the marriage declaration, the registry office may not have the information required to proceed with the file.

Before relying on a proxy, make sure the wording reflects the choices you are actually making. The representative’s authority needs to cover the relevant marriage details; a generic document should not be assumed to meet those requirements. This is particularly relevant when one partner lives abroad and travelling to Portugal is difficult to arrange.

Legal assistance can help review the power of attorney and compare it with the marriage declaration before the document is signed. That preparation does not guarantee authorisation, but it can help avoid a mismatch that requires a corrected document. Our legal support for marriage in Portugal can include document review and assistance with preparation of the file.

Two examples of choosing a route

Imagine a British partner and a Portuguese partner who want to marry in Lisbon, but cannot book a counter appointment at their preferred office. They can consider attending a registry office without an appointment or starting the process at another registry office. They will still need to agree the ceremony’s date, time and place with the registrar.

The British partner’s file must include the required foreign-national documents: identification, a birth certificate and a certificate of matrimonial capacity if the country issues one. The certificate must be less than six months old. If it is not in English, French or Spanish, it needs a certified Portuguese translation. The standard registration costs €120; a qualifying non-urgent weekend or off-site ceremony costs €200.

Now imagine two foreign nationals who are visiting Portugal and hope to marry during their stay. They should prepare the required foreign-national documents and begin the process at least one month before the intended date. If the registry office authorises the marriage, the ceremony must take place within six months of that authorisation.

For either couple, the practical decision is whether to approach another registry office, attend without an appointment or use the online route if eligible. The document requirements and ceremony arrangements still need to be addressed, regardless of which office receives the initial declaration. Fees depend on the ceremony arrangements and any prenuptial agreement.

When the marriage process is delayed

A delay can arise at different points: you may be waiting to attend, waiting for confirmation of an online request, or waiting for the registry office to examine the marriage file. Identify which stage is holding up your plans before changing venues or making another booking. The next useful step depends on whether the issue concerns an appointment, documents or authorisation.

Keep the documents you submitted and any confirmation or correspondence together. If you have not received confirmation of an online appointment, the booking has not yet been marked. If you attended in person, record which office you visited and what it asked you to provide, so that any follow-up refers to the actual request made about your file.

Do not rely on an unconfirmed ceremony date when arranging flights, accommodation or a reception. The process has a minimum one-month lead time, and the six-month period to marry begins after authorisation. These are separate points in the process: submitting the declaration does not itself mean that the marriage has been authorised.

Where the file is complicated or communication has stalled, a lawyer can review the sequence of events, check the documents and help prepare a focused request about the next procedural step. Legal support can help you address the specific obstacle in the file and understand which action is available to you, without substituting for the registry office’s decision.

Practical next steps

First, decide whether you need to start the file, secure a confirmed appointment or agree a ceremony date. Those are different tasks, and knowing which one is outstanding helps you choose between attending without an appointment, approaching another registry office or using the online process if you qualify.

Next, check each partner’s documents and the intended property regime before submitting the declaration. If one partner cannot attend, review the power of attorney against the required details. If the ceremony will be outside normal hours or away from the registry office, agree the arrangement with the registrar and account for the applicable cost.

If appointment difficulties or a document issue are affecting your plans, legal assistance can help you assess the file and prepare the next steps. A lawyer can review the documents, clarify the available procedural options and assist with the preparation and follow-up of the marriage process.
