Kernrechtsfrage
Whether joint parental custody should be replaced by sole custody of the mother
Extrahierter Entscheid
No sufficient change of circumstances or concrete endangerment of the child's welfare was shown; joint custody remained compatible with the child's interests.
Extrahierte Begründung
For an amendment under Art. 134 ZGB, a change is required only if the existing arrangement has become incompatible with the child's welfare and the change is compelling. The record showed a stable relationship with both parents, no proven new danger, and support through a guardianship.
