This can be done in the case, for example, in which it is proved in the case that he has the necessary parental and educational qualities, as well as the relevant material conditions to raise and educate the child.
When it is proven that the child feels well in the way he was raised by the father for a long time (for example for two years during the actual separation between the parents) and nothing requires this way to be changed in the future.
If the mother also has the necessary parenting and upbringing qualities and cares equally for the welfare of the child, but it is proved that she can continue to participate only in his upbringing, through an extended regime of personal relations with him the court awards in favor. the father's parental rights in respect of their common child. In these measures regarding the exercise of parental rights, the mother should participate in the monthly maintenance, which corresponds to the child's need for maintenance and the material possibilities of the mother, taking into account the fact that the father will take immediate care of his upbringing.
It should be taken into account that in these cases the children have an interest in assigning parental rights to this parent, who, given his age, gender and level of development, is better able to provide adequate care not only for everyday life, but also for their good upbringing and development as adults, which is impossible to achieve without a full relationship with the other parent. When, during the de facto separation, with the consent of the parents or for objective reasons, the children are brought up with one parent for a long time, it is in their interest to continue to be brought up by the same parent if he has the necessary qualities and conditions. The most important among the personal qualities of the parent is to recognize and respect the interest of children to have a full relationship with the other parent. The age of the children also matters. When it is too low, they need daily maternal care and affection. An important indicator is whether children feel well in the conditions under which they were raised after the actual separation. Especially when the relations between the parents are intolerable, a new change in the way the children are brought up would in any case have an adverse effect on their already burdened psyche.
