Registration of Marriage in the Population Information System

If you are a Finnish citizen and you get married abroad, you must notify the marriage to the Finnish Population System.

Ask the person conducting the marriage, what documents are needed when the ceremony is performed before a foreign public authority. A Finnish certificate of no impediment can be ordered in multiple languages from the Local Registry Office in your municipality of residence. Documents that are used abroad, must be legalised.

Some priests working among expatriate Finns, who are employed by Evangelical Lutheran Church of Finland, have the right to conduct marriages abroad. For further information, visit the website.

You cannot get married at an embassy of Finland.

Notify the marriage to the Local Register Office

When a Finnish citizen gets married outside Finland it must be notified to the Local Register Office. You can also leave the notification at a Finnish embassy or send it there to be posted to the Local Register Office for registration.

The original marriage certificate or a copy of it, authenticated at the mission of Finland, must be appended to the notification. The document must be legalised and if it has been issued in some other language than Finnish, Swedish or English, an authorised translation in one of these languages must be provided. Translations made abroad must be legalised. Translations made by an authorised translator in Finland are valid as such.

An Apostille stamp is not required for a marriage certificate, which is issued by an EU country authority and a translation of the certificate is not needed if a multilingual standard form is appended to the document.

Notifying of a marriage in Hong Kong

A Finnish citizen married in Hong Kong should notify the Local Register Office in Finland of the marriage with the following documents:


The notification form and all the appendices should be mailed to the Pietarsaari Unit of the Local Register Office of West Finland  (Address: Länsi-Suomen maistraatti, Pietarsaaren yksikkö, PL 26, 68601 Pietarsaari, Finland) or to the Consulate General of Finland in Hong Kong. Alternatively you can mail the form with its appendices to the Local Register Office of the municipality where the Finnish citizen was most recently a resident in Finland. All sections of the form must be carefully filled and both spouses must sign the form. If a spouse’s family name changes after the marriage, the change of name should also be announced in the form. You can find more information on the change of name as a result of a civil union at the Local Register Office website.
