Key legal question
Whether joint parental custody should be replaced by sole custody of the mother
Extracted holding
No sufficient change of circumstances or concrete endangerment of the child's welfare was shown; joint custody remained compatible with the child's interests.
Extracted reasoning
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.
