How can you Request a marriage certificate?

The certificate may be online or issued in paper:

  • Online certificate - It is requested online, issued in electronic support and able to be consulted online for six months.
  • In paper - It may be requested in person and, usually, it has no validity term.

If the marriage registry is over 50 years old, before requesting the certificate, contact the registry office to know if the registry has already been sent to the district archive. If it has been sent to the district archive, you must request the certificate directly to the archive.

Request a certificate online

  1. Go to the Civil Online webpage.
  2. Pick one of the following options:
  • “Sign in with authentication”, if you hold a citizen card or a lawyer, notary or solicitor’s professional license
  • “Sign in without authentication”.
  1. Follow the instructions.
  2. When the certificate is available, you will receive an email or SMS with the code to consult the certificate.
  3. After becoming available, the certificate may be consulted for six months, through the access code sent. If any entity asks you for a marriage certificate, you may give them the access code (the online certificate has the same legal value as a paper certificate).

The online certificate always presents the information present in the marriage registry at its date of issue (that is, during the six months of validity, if there are any amendments to the registry, the certificate is not updated).

Request a certificate issued in paper

  1. Go to a service desk.
  2. Indicate all the data you are aware of from the marriage registry (registry number and year and registry office) or from the couple (such as the full name, date of marriage, parentage and place of birth).
  3. The certificate is issued in paper support and delivered in the moment.
