Triplets and quadruplets will begin to be officially registered in California. Now participants in polyamorous unions will be able to register their relationships with the city administration and receive several additional rights, including the possibility to visit partners in hospitals and enjoy additional benefits when renting housing. According to the new rules, three or more people will be able to register a partnership by submitting an appropriate application to the municipal clerk. Among the mandatory conditions are mutual consent of all participants and the absence of family ties between them. The Californian family surpassed even the Swedish one.
