nimenvaihdos

Nimenvaihdos, a Finnish term, refers to the legal process of changing one's given name or surname. This procedure is governed by Finnish law and typically requires an application to the Digital and Population Data Services Agency (Digi- ja väestötietovirasto).

Individuals can seek to change their name for various reasons. These may include personal preference, to align with their gender identity, to adopt a deceased relative's surname, to simplify a complicated name, or to sever ties with a family name due to negative associations. While there are many acceptable reasons, certain restrictions apply. Names that are offensive, could cause harm, or are exceptionally unusual might be rejected. Similarly, names that are already common among a large population, or names that are clearly surnames of another person (unless there is a strong justification), may also face difficulties.

The application process involves submitting a form along with supporting documentation, which may include a valid reason for the change. If the application is approved, the name change is registered in the Finnish population information system. This updated information then appears on official documents such as identification cards and passports. The change of name is a public record, though the specific reasons for the change are not always made public unless deemed necessary for the justification.
