Lag (1904:26 s.1) om vissa internationella rättsförhållanden rörande äktenskap och förmynderskap (1904: 2 - Act on certain international legal marriages and wardships)

This act contains relevant provisions regarding marriage recognition. In 2004, major restrictions were adopted in relation to child marriages and forced marriages that have been entered into abroad to discourage circumvention of Swedish law in cases of strong Swedish affiliation. According to the act, a marriage that has been entered into under foreign law is not recognized in Sweden:

1. if, at the time of the marriage, any of the parties was under the age of 18
2. if, at the time of the marriage, there would have been any other issue with the marriage under Swedish law, and at least one of the parties was at the time a Swedish citizen or was domiciled in Sweden
3. if it is likely that the marriage was forced, or
4. if the parties were not present at the same time during the marriage and at least one of them was at the time a Swedish citizen or was domiciled in Sweden.

The above does not apply if both parties are over the age of 18 and there are special reasons to recognize the marriage.
