Does anyone know anything about that? I've been told that I should look into it, but I have no idea how to even start. My dad was gone all of my life until a month before I turned 18, and expected me to be his best friend.. which I'm NOT wanting to do. But anyways, back to the money he owes me. Can a child sue a parent for not paid child support when they're an adult? I'm 19, in case that matters. Thanks in advance for the input.
