The Parliament of Sweden has passed a new law prohibiting marriages between cousins and several categories of close relatives as part of broader efforts to address forced unions, honour-related abuse and domestic violence.
The legislation, which received unanimous approval from lawmakers, will prevent cousin marriages from being legally conducted within Sweden and will also restrict official recognition of such unions performed outside the country.
Under the new legal framework, marriages involving individuals closely connected through siblings, including certain extended family relationships, will also be prohibited. The law further bans unions between half-siblings and adopted siblings in a move authorities say is aimed at strengthening protections for vulnerable individuals.
Brandspur Politics reports that Swedish lawmakers introduced the reform amid increasing concerns over family pressure, cultural coercion and honour-based practices affecting women and young people in some communities.
Officials said the legislation is designed to safeguard personal freedom and ensure that marriage decisions are made voluntarily without intimidation or external influence from relatives or family networks.
The new marriage restrictions are scheduled to officially take effect across Sweden from July 1, 2026, as authorities prepare for implementation and enforcement of the updated family laws.
