Questão jurídica principal
Whether sole parental custody should be awarded to the father instead of maintaining joint custody.
Decisão extraída
Joint parental custody should remain in place because the existing child-protection measures and support structures sufficiently mitigate the parents' conflict and the children's welfare would not be better protected by sole custody.
Fundamentação extraída
Sole custody is an exceptional measure under Swiss law and requires a serious, chronic conflict that significantly harms the child and is likely to improve through one-parent custody. Here, the children were not in either parent's care, regular contact with both parents continued, and the KESB and guardianship support already addressed the mother's deficiencies. Excluding the mother from decisions would likely intensify conflict rather than improve the situation.
