Registering a Foreign Marriage in Portugal

If a Portuguese citizen marries abroad before a foreign authority, the marriage can be transcribed into the Portuguese civil registry.

This is called transcrição do casamento.

It is not a second marriage and it is not the same thing as getting married in Portugal.

The purpose is to create the Portuguese civil-registry record of a marriage that already legally took place abroad.

Who normally needs this?

The clearest case is:

a Portuguese citizen married abroad before foreign authorities.

The Portuguese spouse can request transcription through:

• a Portuguese consular post;
• a Civil Registry Office in Portugal.

If the marriage was celebrated abroad before Portuguese consular authorities, a separate transcription request is not needed.

Do two foreign spouses need Portuguese transcription?

Not automatically.

Two foreign nationals who married abroad generally use their foreign marriage certificate for the Portuguese procedure that needs proof of marriage.

That document may need authentication and translation.

Do not create a transcription process simply because the couple now lives in Portugal.

The right question is whether Portuguese law or the specific procedure requires a Portuguese civil-registry entry.

Why does transcription matter for a Portuguese citizen?

Portuguese civil status should reflect the marriage.

The registered marriage can also become relevant for later matters such as:

• residence of a foreign spouse;
• nationality by marriage;
• children and civil registration;
• inheritance;
• matrimonial-property questions;
• other Portuguese administrative procedures.

The exact downstream process may have its own requirements.

What documents does IRN list?

Current IRN guidance identifies:

• the foreign marriage certificate;
• an authenticated copy of the prenuptial agreement, if one was made;
• the birth certificate of a spouse who is foreign.

The actual file can require additional identification or supporting documents depending on the marriage and the country involved.

Does the foreign marriage certificate need an apostille?

It depends on where the certificate was issued.

EU public documents

Certain public documents issued by an EU Member State benefit from EU rules that remove the apostille requirement for matters including marriage and civil status.

A multilingual standard form can also simplify translation in some cases.

Hague Apostille countries

For a public marriage certificate from a Hague Apostille Convention country, apostille is commonly the authentication route.

Other countries

Consular legalisation or another recognised route may apply.

Do not assume every marriage certificate needs the same formalities.

Does it need Portuguese translation?

As a general rule, foreign-language documents used for Portuguese civil-registration acts should have a certified Portuguese translation.

IRN also recognises exceptions.

Translation may be dispensed with where the document is in English, French or Spanish and the competent registry officer understands that language.

EU multilingual forms can also affect the translation requirement.

Always check the actual document and receiving registry.

What if there was a prenuptial agreement?

If the couple signed a prenuptial agreement before the foreign marriage, it can be important to the Portuguese registration.

IRN specifically lists an authenticated copy of the prenuptial agreement where one exists.

International property regimes can be more complex than simply translating the name of the foreign regime.

If the couple has significant assets, property in several countries or a non-standard agreement, review the property consequences separately.

What if one spouse was previously divorced?

The civil-status chain must make sense.

If the previous marriage or divorce is not already reflected correctly in the relevant Portuguese record, additional work may be needed before the new foreign marriage can be transcribed.

The answer depends on:

• which spouse was previously married;
• where the divorce took place;
• whether it was judicial or administrative;
• whether EU recognition rules apply;
• whether Portuguese recognition or registration is still needed.

This is a common reason to review the file before ordering translations.

Can a lawyer handle the transcription?

Legal representation can be used for Portuguese civil-registry work where the required powers and documents are in place.

For clients abroad, this can avoid unnecessary travel for document preparation and registry follow-up.

The exact signing and representation requirements should be checked for the case.

How long does it take?

IRN does not publish one guaranteed processing time that applies to every foreign marriage transcription.

Timing depends on:

• registry workload;
• country of marriage;
• document quality;
• previous civil-status issues;
• matrimonial-property questions;
• requests for additional documents.

Be careful with anyone presenting one fixed processing time as if it were statutory.

Transcription and foreign-spouse residence

If the Portuguese citizen's spouse is non-EU and plans to live in Portugal, residence is a separate procedure.

The marriage record supports the family relationship.

AIMA still handles the residence-card process under the applicable family framework.

Transcription and nationality by marriage

Nationality is also separate.

Under the law in force from 19 May 2026, a foreign spouse can have a marriage-based nationality route after more than three years of marriage, subject to the applicable conditions.

The Portuguese marriage record can be important for that file, but transcription itself does not grant nationality.

Common mistakes

Treating transcription as another marriage ceremony

It is registration of an existing foreign marriage.

Assuming every foreign couple needs it

Two foreign spouses generally do not transcribe merely because they reside in Portugal.

Translating before checking authentication

The document route should be planned in the correct order.

Ignoring a foreign prenuptial agreement

It can be part of the Portuguese registration file.

Discovering an old divorce only after filing

Previous civil status can block or delay the transcription.
