The father of my daughter whom will be 3 in march is no longer paying child support or carrying medical insurance on her (hasn't been for 3 months now). It states in our decree that he must carry insurance and pay child support plus have life insurance on himself. Mean while i am to pay the first 250 of medical expenses then we both pay 50/50 of whats left. He's never paid me a dime to help with medical expenses and now he's not carrying insurance on her or paying child support. So my question is do i have to let him take her for his visitation thats also in our decree?? if so then why is there even a decree if he can get away with not helping support our daughter yet still gets to do as he pleases and takes her.
