i am a single parent trying to collect child support. the non custodial parent now married and he and his wife have a child. they decided it would be best for them that she works and he stays at home to take care of the kids. due to this he has very little to no income of his own. now child support enforcement in missouri says that i am responsible for about 80 percent of what they say it cost to raise a child. is there a law that goes off of household income in this situation or can they base it off of something else since he is able to work just choosing not to?
