<prompt> Human: Im a 23 year old full time grad student and employed part time. My parents have been divorced since I was 9, since they split my dad claimed me as dependent and my mom claimed my other two siblings. He paid child support up until my youngest sibling turned 18 I was 19. My father never helped with my tuition throughout my undergrad and certainly not with my graduate tuition. Last year was the first time I claimed myself on my taxes and it was the first year I did not owe any money. Unfortunately my father is more concerned about the money he lost from not being able to claim me, and told me he was going to claim me this year. Long story short, he did, and I found out when I went to file my taxes on my own. So I went ahead and said that I cannot be claimed as a dependent and Im waiting for either of us to be audited. For the record I have always lived with my mom and never once shared an address with him after he moved out. I guess I am concerned as to what happens if he wants to fight this or take it to the powers that be. Does he have any grounds to be able to do this? I just want to prepare myself for whatever happens. Thanks so much in advance.  <response>: you are 23 and he cant show how he provided 50 of your living expenses...he has to prove that, not you...
