I believe that if there is a court order for child support then that should not change regardless of other child he decides to take care of. Any non-written or verbal agreements usually do not hold up in court. Since you do have a written court order of child support, I would think that you would be notified of any change or at least contacted in regards to any action taken to change it. KEEP all records of any payments he has and has NOT paid you so that you can take action to extract that money from him that he owes in child support. Do you have an attorney?

I don't have an attorney. I haven't really felt the need to get one yet. I have records of the money he's fallen behind on, the times he's been late, the times he doesn't show up, when he doesn't call/text to let me know he's not coming, etc. I know the verbal agreement won't hold up in court but I guess that's what I get for trusting him.
