V.S.
Hello S.. I can only answer the question about back child support because that's all I have experience with. No, you can NOT get back child support if there has never been an order for it. I know this because my daughter's father filed for child support when she briefly lived with him. I was livid because he never paid me a dime in the 10 years she lived with me, so I called the child support office and asked if I could counter act with child support for all the years he never paid me. Simply put, they said no, unless there had been a court oder for it that he did not abide by. Of course, there hadn't been, because we had both agreed when we split that we wouldn't go down that road, that whatever she needed, it would be provided by the parent who could do it at the time. Sorry :(
