TL;DR

Sweden will ban marriages between first cousins and other close relatives, according to a law taking effect July 1, 2026. The legislation targets consanguineous unions, which have been linked to higher risks of genetic disorders in offspring.

01 · THE DISPATCH

Sweden is set to become the latest European country to ban cousin marriages, with the law coming into force on July 1, 2026. The legislation prohibits marriages between first cousins and other close relatives, a practice that remains common in some immigrant communities. Swedish authorities cite increased risks of congenital disorders among children of consanguineous unions as the primary reason for the ban. The law will apply to all residents, with no exemptions for religious or cultural practices.
