The naming law in Sweden (Swedish: lag om personnamn)[1] is a Swedish law which requires the approval of the government agency for names to be given to Swedish children. The parents must submit the proposed name of a child within three months of birth. The current law was enacted in 2017, replacing a 1982 law. The Swedish Tax Agency administers the registration of names in Sweden. The law has been revised since originally enacted; in 1983, it was made possible for a man to adopt his wife's or partner's name, as well as for a woman to adopt her husband's name.
The 2017 law states, in part: "First names shall not be approved if they can lead to discomfort for the person bearing the name, or for any other reason is unsuitable as a name" (§ 28). This text applies both when parents name their children and when an adult wants to change their own name. Unlike the 1982 law, the 2017 law gives the Swedish Tax Agency the ability to charge a fee for requesting to change your name. The law states nothing about registering which name is used on a daily basis, but the tax authority can register that if requested.
