I have my daughter half the week and her mother has her the other half, yet she has full custody of my daughter and I have to pay 800 a month in child support and her mother gets to claim her on her taxes every year. How do I change this I believe since I have my daughter half the time anyway, we should have split custody and neither one of us needs to pay the other. Is this possible? last time we went to court the above is what the judge ordered. My fear is that all these years it is looking like I do not have my daughter but I do. What can I do? I dont think her mother will agree to split custody if she doesnt get all the child supprt she has been getting for years.
