I do not know the law in most states and am not an attorney. But, in child custody and support matters, generally speaking the court becomes an advocate for the child and when my divorce from my son's father occurred, the law was, there was no bickering allowed about child support. It depended upon the total income of the two supporting parents, divided according the percentage of the total being provided by each parent. There was a chart that the state used, if the total income was a certain amount, then the support was a certain amount, with a specified percentage coming from each parent.

Now, having said this, if one parent provides things for the child, such as private school tuition, or airline fare for visitation, or other things that are out of the ordinary, those can be taken into consideration but they cannot be taken into consideration if the court doesn't know about them. Your BF needs to get himself into court so he can take an active part in what is happening to him.

Is he seeing his children at all? He needs to be proactive in this matter. How long does he plan to continue playing the victim?

How much longer do you plan to continue allowing him to do it? I hope you can figure out a way to get him to move on this and do so soon.
