My question involves a child custody case from the State of: Florida

My husband and I had children outside of our marriage then had a baby together. His ex has refused to let him see his daughter since August of 2009, right after the new baby was born. He pays an arm and a leg in child support, and we have not protested it yet even though we know she was lying about her monthly income. He has almost quit trying because it is so upsetting to him and to our children when we tell them they get to see their sister and then we get excuses or even sometimes nothing. She has recently married and I am worried about him. We can't afford an attorney and when I call around everyone is taking cases that involve dometic violence or they had to have been married. i continue to push him to keep calling and keep trying but it just ends up with us arguing. I can't imagine what he is going through since I have my two daughters with me night and day, and he on the other hand hasn't seen her in over a year. Please help us.
