Hello- I'm a single mom with a son. My son's father has 6 kids and is crying broke for the modification I filed for 1/2 child care and 1/2 prescription costs (my son has existing medical conditions). I can't afford a lawyer so I have to prove my case at trial. How the heck do I do that? I know that I'm entitiled to the money, but I don't even know where to start.
