Ok understand that I am not telling you to grease the wheels for a D. Just that you should be prepared and know your rights. You can get a free consult with a D lawyer. Interview a few of them, see what you learn. Do not tell this to the H. You are doing this for you and your children. He is moving out, he needs to help with child support. The most important thing right now is not H. It is you and your children!
