In the Netherlands, a new law allows parents to give their children a combined surname, but only with mutual consent. Recent data reveals that 6% of babies born this year have received such names. However, the requirement for both parents’ agreement has led to legal challenges, particularly among divorced parents. Women’s rights organizations argue that the law is discriminatory, as it disproportionately affects mothers who wish to add their surname but are denied by their ex-partners. Calls for legal reform and an extension of the transition period are increasing.
