Child-related budget and child benefit in co-parenting

Questioner

I am currently going through a divorce. We have 4 children. My (ex)wife does not work, so has no income. The judge has now determined in the order that the care and upbringing tasks must be divided equally between both parents, i.e. co-parenting. Because my (ex)wife had no income, it seemed most favorable to me that the children were registered with her. The judge therefore also included this in the order. However, I now read on the internet that with co-parenting both parents are entitled to half of KGB and KB. I have made some test calculations and they show that it is more beneficial to have 2 children registered with me and 2 with my (ex)wife. My question: Where is it legally established that KGB and KB must be divided in the case of co-parenting? Or is that incorrect? Can we decide for ourselves how this is arranged, whether 2 children are registered with each parent, or all four with a parent who transfers half of the KGB and KB to the other parent? Even if a statement about this has been made in the order? And if the other parent does not cooperate with this, keeps all the money from KGB and KB for themselves, what can I do about that?

Child benefit and child-related budget are received by the person at whose address the child in question is registered. However, you can jointly inform the Social Insurance Bank (SVB) to what extent the child benefit should be divided between you. If there is no consultation between the two, the determining factor is where the children have their main residence. The children must be registered with the municipality at that last address. The child-related budget is linked to the child benefit. In general, it is advantageous to divide the registration of the children between the two of you. In general, the child-related budget is higher for the person with a lower income. In order to find out exactly what is most advantageous for you, one or more maintenance calculations must be carried out. I notice that the amount of child support depends on the choice of dividing the children between the two of you.
