Marriage concluded abroad
If you have got married abroad, please notify us following the instructions on this page. We will record the information about your marriage in the Finnish Population Information System to keep your personal data up to date. At the same time, we can record your surname if it changed when you got married. If you are a Finnish citizen, you have the obligation to notify any changes in your personal data to the Finnish Population Information System.
Recording a changed surname
If you changed your surname when you got married, we can also record your new surname. The change of surname should be indicated either in the marriage certificate or the proof of identity document.
However, if your new surname is not shown in the marriage certificate or your proof of identity document, we can register your new surname based on your notification under certain conditions. This is possible if you live in Finland or are a Finnish citizen and if your spouse consents to adopting his/her surname. We can also register your new surname based on a separate certificate.

Finnish citizens living in Sweden
The Swedish authorities will inform us of the marriage. If you are a citizen of both Finland and Sweden, Sweden considers you to be a Swedish citizen only and will not forward the information. Persons with dual citizenship therefore have to submit the notification themselves.
