Questão jurídica principal
Whether the divorce custody arrangement should be provisionally modified for the pending proceedings.
Decisão extraída
The custody arrangement had to be provisionally changed because the children's welfare was best served by placing the older two children with the father, while the youngest remained with the mother.
Fundamentação extraída
A material change of circumstances existed: the mother had left Switzerland with the youngest child and the children's situation had changed fundamentally. The KOFA report, the child representative, the guardian and the children's own statements supported a split arrangement based on welfare.
