Don't know if this adds anything to the discussion but I pay CS to my X. Of course I pay the court ordered amount (actually it's garnished from my pay) but I have to say it still irritates me that I have to pay. I have the higher income so I pay the support. I get that. We have 50-50 physical custody so the kids are in each of our households an equal amount of time. The reason it irritates me is be/c my X is fully educated and and qualified to get a job paying at least as much as I make but chooses not to. He chooses to work only part time and at a job that pays less than many others in his field. So because of his choices I have to pay money to him every month and it does not seem fair to me.
Did the court impute full-time income to him? If not, you may want to revisit child support with a different attorney.
