Motifs extraits
The parents were no longer able to cooperate on fundamental child-related decisions, as shown by their divergent requests and the mother's unilateral decisions on schooling and domicile. Applying the child's welfare criteria, the father was found slightly more available, equally fit educationally, and better able to foster contact with the other parent.
