So there is a question someone asked about getting retro support and I have my own questions with this topic but didn't want to thread steal or anything. I really don't know how this stuff works and if i dont this may help others too. So if a child was born two years ago could the childs mother file for support and get those years worth of support back? is that the idea of what retro support is? How far back can they go? can a pregnant woman get support? once support is set up and has been in force for years can mom go back to court for her retro support?
